Why they do it.

British Bombers’ Rage Formed in a Caldron of Discontent – New York Times
July 31, 2005
By AMY WALDMAN

LEEDS, England, July 30 – Mohammad Sidique Khan was never on the corner, a detail friends offer as a compliment. In a neighborhood where many young South Asian men had lost their way, or foundered into drug dealing, Mr. Khan’s peers admired his focus on family, work, working out, and Islam.

The discipline of Mr. Khan, 30, was shared, and not just with his friends Shehzad Tanweer, 22, and Hasib Mir Hussain, 18, who joined him on a murderous assignation in London on July 7. The three men and Germaine Lindsay, 19, detonated four bombs that killed 56 people, including themselves.

Mr. Khan, Mr. Tanweer and Mr. Hussain were part of a larger clique of young British-raised South Asian men in Beeston, a neighborhood of Leeds, who turned their backs on what they came to see as a decadent, demoralizing Western culture. Instead, the group embraced an Islam whose practice was often far more fundamentalist than their fathers’, and always more political, focused passionately on Muslim suffering at Western hands.

In many ways, the transformation has had positive elements: the men live healthier and more constructive lives than many of their peers here, Asian or white, who have fallen prey to drugs, alcohol or petty crime. Why Mr. Khan, Mr. Tanweer and Mr. Hussain in particular crossed a line that no one had before, how they and Mr. Lindsay linked up, or whether their plot was homegrown or steered from outside, remain mysteries, at least to the public.

But the question asked since their identities were revealed after the bombings continues to resonate: what motivated men reared thousands of miles from the oppression that outraged them to bomb fellow Britons, ushering in a new chapter of terrorism?

Many here see answers in the sense of injustice at events both at home and abroad that is far more widespread among Muslims than many Westerners recognize; in the rigid and deeply political form of Islam that increasing numbers of educated European Muslims are gravitating to; in the difficulty some children of Muslim immigrants in Europe have had in finding their place or direction.

It is a broader narrative being played out by such immigrants across Britain, and Western Europe. The young men here grew up brown-skinned in white Britain, in a blighted pocket of Leeds straddling their parents’ traditional values and the working-class culture around them. They have been reared shoulder to shoulder with old stone churches and young hooligans, and face to face with attitudes toward family and morality different from those taught by their parents.

“They don’t know whether they’re Muslim or British or both,” said Martin McDaid, a former antiterrorist operative who converted to Islam, taking the name Abdullah, and worked in the neighborhood.

They are alienated from their parents’ rural South Asian culture, which they see as backward. Reared in an often racist milieu, they feel excluded from mainstream British society, which has so far not yielded to hyphenated immigrant identities as America has. They have come of age in an era marked by conflicts between Muslims and better armed powers – India, Serbia, Russia, Israel, America and Britain – and the rise of an ideology that sanctifies terrorist attacks against the West in response.

So some young men have solved the “don’t know” riddle by discovering a new assertive and transnational identity as Muslims. The change has played out within families in the small, brick “back-to-back” terraced houses of little Beeston’s lattice of down-at-the-heels streets.

In one corner shop sits Ejaz Hussain, 54, who came from a Pakistani village in his teens, and has reared eight children in Britain. The bombers’ fathers and he worshiped at the same mosque; their sons left, rejecting the mosque’s form of Islam as incorrect and its determination to keep politics outside the mosque as unjust.

Walk down Stratford Street, past another mosque of the elders the bombers and their cohort rejected, to the store of Mohammad Jaheer, a burly Bangladesh-born shopkeeper who went “religious,” as young men here say, 10 years ago at 16. Islam has saved him from what he calls an animal-like life as a Western businessman spending time at clubs, he said. He helped form the Iqra Learning Center, an Islamic bookshop, five years ago, to educate Muslims and non-Muslims about the faith.

That bookshop, just a few blocks from his shop, was raided by the police because of its possible links to the bombers. Over time its education came to include provocative material that some contend was meant to inspire jihad.

Mr. McDaid, who worked at the bookshop, said it was intended only to raise awareness and passions – among Muslims and the British establishment alike – about the oppression of Muslims around the world.

Passions have been raised, among the bombers most radically, but among many others here and across Europe. Mr. Hussain, who helped organize two peace marches in the bombings’ wake, rejects the notion that an outsider from Al Qaeda recruited the men, although others disagree.

He pointed to his head and said in reference to the bombers, and their peers: “Al Qaeda is inside.”

An Epic Migration

Ejaz Hussain was 16 when he left his 40-household village in Pakistan and came to Britain in 1967. Everybody was going; no one planned to stay long. He did not realize that he and so many others were part of an epic, and permanent, migration that would reshape Britain in so many ways, the events of July 7 being just one.

The British Raj officially ended on Aug. 15, 1947, but its relationship to its subjects did not. In the following decades men of the Indian subcontinent came to Britain en masse to supply cheap, unskilled labor for factories, foundries and, especially, textile mills in northern Britain.

The majority of the immigrants were Mulsim farmers from the Mirpur region of Pakistani Kashmir. Others came from Gujarat in India, or what is now Bangladesh, or, as with the bombers’ families, Punjab Province in Pakistan. Most were poor, with rural backgrounds and often uneducated, although Mr. Hussain, the thoughtful, genteel son of a policeman, had more education than most.

They started with perhaps £5 in their pocket, and worked 16 to 18 hours a day, with a beaverlike determination to earn and build something for the next generation.

Mr. Hussain, now 54, worked in factories and mills, drove a taxi, and has run a corner minimart for 15 years.

Integration was minimal, thanks to barriers of race and language, culture and religion. The migrants were the colonized who came to live among their former colonizers. “When we came we were like servants,” Mr. Hussain said. Even though they had time for little beyond Friday Prayer, if that, they were Muslims still, for whom true assimilation into Western ways, like drinking, would inevitably be irreligious.

Many, Mr. Hussain among them, thought they would earn and then go home. Instead, they eventually brought over wives or young families, forming insular communities in which English fluency was dispensable.

In the late 1980’s, most of the mills and factories closed. Men began driving taxis, or opened shops or other family-run businesses that require round-the-clock tending by an extended family. Others simply retired.

The first wave’s attitude was, and largely still is, one of gratitude toward Britain, which offered a livelihood and left them alone to practice their religion.

“Britain is the greatest country in the world” for those reasons, boomed Arif Butt, a forceful figure in Beeston who runs one of its mosques and has clashed with its youth.

Arshad Chaudhry, an accountant and member of the Leeds Muslim Forum, sees it differently. “They were very timid,” he said of the first wave.

Tough Neighborhoods

Beeston Hill, where Mohammad Sidique Khan and Shehzad Tanweer were raised, and nearby Holbeck, where Hasib Mir Hussain grew up, have a dreary, dissolute air. The houses somehow seem shrunken in scale, and the dreams of many youth seem to have been sized to match.

The two neighborhoods are about 77 percent white and 18 percent “Asian or Asian British,” according to the 2001 census. Almost half the population is under 30.

Many white residents of Beeston tend toward tattoos and pit bulls. The drinking starts early, and openly. Trash and furniture clot some streets. Faces have been ravaged by drugs, whose use peaked a few years ago when legions of zombielike heroin addicts wandered the streets.

More than 10 percent of houses are vacant. Nearly a third of the population of about 16,000 receives the British equivalent of welfare. Unemployment is nearly 8 percent, more than double the rate for the rest of Leeds.

Whites and Asians live for the most part politely, but distantly, adjacent. Both groups say South Asians have actually prospered more than whites, which has generated some resentment. Plenty of British Muslims face staggering poverty and unemployment, but the bombers and their immediate circle were not among them. At least some youth seem more directionless than deprived.

In some ways, Mr. Hussain and other elders say, the young people have had it easy. At the age when their fathers worked like mules, the sons are playing cricket, studying, hanging out. Compared with their parents, they are well educated, thoroughly literate, fluent in English and the Internet.

Some know family businesses are waiting for them to take over. Some go on welfare as soon as they reach adulthood. Some sell drugs. “They are getting lazy, getting spoiled from the government,” said Abu Hanifa, 60, another shopkeeper who works around the clock.

And yet Mr. Hussain and others think the young have also had it harder. In an alien culture, work ballasted the migrants, as did the traditional values they had imported from home. The young have no such anchors; they sometimes seem to be living in rooms without walls.

Mohammad Sidique Khan’s generation was the first to be educated entirely in Britain. The schools they attended made almost no accommodation to their presence. They learned almost nothing about Pakistan or Islam’s history and traditions.

Instead, they were expected to become British, and many have tried. But in areas like Beeston, they say, that has also meant learning to drink, using or selling drugs and losing one’s virginity at an early age.

They grew up in rough and often blighted neighborhoods where “hardness” – the ability to fight anyone, at any time – was essential, said Mr. Hussain’s son Nadeem Ejaz, 30, who runs the family’s green grocery. The red shoelaces favored by young racists from the National Front remain etched in his teenage memories.

Many young Muslims, Mr. Khan among them, turned to martial arts or boxing partly to ensure combat readiness.

Boys regularly divide into white and Asian gangs. In April, a 15-year-old boy was stabbed to death by a member of an Asian mob that pursued him.

The children of the immigrants have shed the servility, and passivity, of their parents, Mr. Hussain said. They want their rights, even if they have to fight for them. This inspires both pride and unease in him.

Mr. Hussain sees a continuum of self-destruction between the recent bombings and race riots that occurred just 10 miles away in 2001 – seemingly disconnected rage. “Why this damage to their own streets, their own cities, their own communities?” he asked of the Asian youth who participated in the riots, echoing those who now ask how the bombers could turn on their own society. “Maybe if we had paid attention then this wouldn’t have happened.”

A good many young Asian men here are, in British social welfare parlance, NEET: Not in Education, Employment or Training. Here and in other South Asian communities over the past 15 years, they have begun to out-English the English, selling drugs and serving prison terms at alarming rates.

In Stratford Street, a Bengali-British drug dealer with a gold tooth and a practiced air of menace sits on a stoop. Mr. Jaheer, the Bengali-British shopkeeper, passes him by. As Mr. Jaheer and his friends see it, the critical battle here has been between those who have succumbed to their milieu, dragging their community down, and those who have sought to rescue and uplift it.

In that effort to fight Beeston’s addiction, violence and aimlessness, they say Islam has proved an invaluable ally. To those who say Islam turned the bombers against Britain, they answer that Islam also saved youngsters from Britain.

The Draw of Religion

Mr. Jaheer was among the first to become religious, and others soon followed. One by one, young men who regularly slept through namaz, or prayers, awakened. Mr. Khan was among them; so, later on, were his fellow bombers, Mr. Tanweer and Mr. Hussain.

The group was always a small minority among Beeston’s youth, but an influential one. The pioneers coached those who followed them in how to live as Muslims in the West, bringing a new social conservatism to bear. It is permissible to look once at scantily clad women in summer, they would tell youth. After that it is a sin. Young men put away their televisions, saying there was no appropriate programming for Muslims, and sometimes imposed new restrictions on their wives.

“They were doing quite well with the young brothers,” said Nadeem Ejaz, crediting Mr. Khan and others with weaning some youth from drugs. “It was smack city around here. These people took on the initiative to clean up the community.”

The group of friends created a network of organizations to lure Asian youth off the streets through sports, nature outings and education. For the Leeds City Council, desperate to counter the social ills present in Beeston and similar communities, the men were an ideal conduit. Over the years the council funneled numerous grants to their organizations and says some worked well.

Mr. Khan was among the grantees. Under the auspices of the South Leeds Asian Youth Association, he twice applied for, and won, grants of about £2,000 apiece for gym equipment, according to council records.

At the same time, the group’s newfound faith was creating distance from its members’ peers, and sometimes conflict with parental choices.

One of Ejaz Hussain’s sons became very religious five years ago. He works at his father’s corner shop, joking with customers, calling the women “luv,” the standard Yorkshire greeting. But the shop sells cigarettes, bacon and tinned pork, girlie magazines.

To him, the shop – the fruit of his father’s life of work – violates his faith, and he has unsuccessfully tried to persuade the family to give it up.

Religiously, the young men came at Islam like converts – questioning everything, accepting nothing. If they were going to practice, they wanted to do it in what they considered the right way. If they wanted to go to heaven, they felt, they had to find the purest form. They wanted evidence for whatever they did in the Koran.

All of the young men quickly rejected the Islam of their parents, who practice a Sufi-influenced strain of the subcontinent called Barelvi. Shaped partly by Hindu and folk customs, it believes in the power of pirs, or holy men, and their shrines.

The young men, Mr. Khan especially vehement among them, believed such “innovations” contaminated Islam.

They stopped praying at their parents’ mosque, even as they used its basement gym to warn youth against the type of Islam their parents practiced upstairs.

They turned, instead, to the more rigid, orthodox Deobandi school of Islam, which also had a mosque in town. The adherents of Deobandism include the Taliban of Afghanistan; they take what they see as a literal approach to the faith. In Britain, as in Pakistan, this school is growing fast – starting seminaries, producing English-speaking preachers and drawing youths away from the more liberal Islam of their parents.

Eventually Mr. Khan and his friends left the Deobandi mosque, too, saying its approach to outreach was too narrow, its focus too apolitical. And the young zealots felt only frustration and contempt for the mosques’ imams, who were often brought from the subcontinent, spoke minimal English, knew nothing of the moral maze young British Muslims face, and abided by an injunction by mosque elders that politics or current events involving Muslims should stay outside the mosque.

A Politicized Islam

For the young, Islam was politics. “There is a lot of hatred” because of Iraq, Kosovo, Kashmir, Mr. Ejaz said. If the mosque makes subjects like that taboo, if their doors are closed, he said, young people are going to go somewhere else.

In Beeston and across Britain, that is exactly what they are doing, which may make Prime Minister Tony Blair’s call for mosques to preach against extremism an exercise in futility.

Educated second-generation Muslims are finding their way to an extreme form of Islam spreading not through mosques but through Islamic bookshops, the Internet and university societies, said Roger Ballard, an anthropologist in Manchester who specializes in Pakistani Muslims in Britain.

The form is called Salafism, taking its name from the term for the Prophet Muhammad’s companions, although its adherents often reject any label. It originated in 19th-century Saudi Arabia, and has helped inspire groups like the Muslim Brotherhood and Al Qaeda.

The Salafi demand for purity and rejection of any Islam except that of the early years can lead to deep intolerance even for other Muslims like Shiites. Salafis see politics as embedded in the DNA of Islam. They take to heart the injunction that the ummah – the global community of Muslims -is “like one body”: if one part is suffering, the rest will be in pain as well. They believe, therefore, in an obligation to physical jihad, or struggle, under the right conditions.

For educated young European Muslims who learned nothing of their own history in school, Salafism is a natural fit, Mr. Ballard said. It provides unequivocal answers. And, he said, it is largely “do it yourself.”

In Beeston, the young men did do it themselves. After they left the mosques they gravitated to the Iqra Learning Center. There, they were free of their elders and their old ways. They held study circles, debated and produced literature and videos, all with an agenda that was political as much as religious.

Their effort to create an Islamic identity in British Muslims has been fueled by the belief that the West is waging a war – a “crusade,” the word President Bush used in 2001 – against Islam, a notion strengthened by the invasion of Iraq.

This notion recurs in the materials circulated by Islamic bookshops and on the Internet. DVD’s produced and distributed by Iqra juxtapose images from the Crusades with images of war-mutilated Muslims. A cross drips blood over Afghanistan. In one DVD are images of what Mr. McDaid called “mujahedeen,” Muslims fighting in an array of conflicts, but he insisted those images were not on the copies given away.

Under new legislation Britain is weighing against “indirect incitement” to terrorism, such DVD’s could become illegal. That perplexes the young men here. One Briton’s propaganda, they point out, is another’s truth. Bloodshed in places like Iraq is not their invention, Mr. Jaheer said. “How can it be incitement if it’s facts?” he asked.

In his shop, Mr. Hussain, whose Islam his children rejected as too liberal, opens the newspaper to an article about 25,000 civilian dead in Iraq in the past two years.

“People keep asking what was in their heads,” he said quietly.

Mr. Hussain changed worlds by coming to Britain, and now the world he made here has been irrevocably changed by its youth. The government says community leaders should police their communities, mosques their devotees, fathers their sons. Outside, police close-circuit television vans prowl, there to protect the community from possible retaliatory attacks, but also to watch.

Sony Admits That It Helped Make Radio Suck, and Lied About It

Sony Agrees to Halt Gifts for Airtime – New York Times
Sony Agrees to Halt Gifts for Airtime

By JENNIFER BAYOT

Published: July 25, 2005

Sony BMG Music Entertainment, one of the world’s largest record companies, agreed today to stop providing lavish gifts, free trips and other giveaways in exchange for airtime for its artists on radio stations, under the terms of a settlement with the New York attorney general’s office.

Eliot Spitzer, the New York State Attorney General, announces an agreement to halt pervasive “pay-for-playî practices in the music industry.

The settlement, which includes a $10 million payment to a fund for music education, is the first in a broad investigation by Eliot Spitzer, the New York attorney general, into incentives that record companies offer to radio stations in hopes of getting airtime that will raise their artists’ profiles, increase a song’s ranking and, of course, drive up sales.

“This agreement is a model for breaking the pervasive influence of bribes in the industry,” Mr. Spitzer said in a statement. “Contrary to listener expectations that songs are selected for airplay based on artistic merit and popularity, air time is often determined by undisclosed payoffs to radio stations and their employees.”

Sony BMG, which represents Jessica Simpson and Jennifer Lopez, among dozens of others, admitted to the misconduct in a statement. “Sony BMG acknowledges that various employees pursued some radio promotion practices on behalf of the company that were wrong and improper, and apologizes for such conduct,” the company said. “SONY BMG looks forward to defining a new, higher standard in radio promotion.”

It also suggested that such practices were common in the industry, even though state and federal laws bar record labels from paying radio stations for air time. “Such direct and indirect forms of what has been described generically as “payola” for spins has continued to be an unfortunately prevalent aspect of radio promotion,” the statement said.

In addition to Sony BMG, a unit of Sony and Bertelsmann, Mr. Spitzer’s office served subpoenas late last year to the Universal Music Group, a unit of Vivendi Universal; the EMI Group; and the Warner Music Group. The attorney general sought copies of contracts, billing records and internal memos; it also questioned senior executives at Sony.

The attorney general said that the enticements took several forms. Station programmers received bribes like computer laptops and vacation packages, or the label sponsored contests for a station’s listeners. In other cases, Sony BMG paid some of a station’s day-to-day expenses, or it hired middlemen known as independent promoters to make illegal payments to radio stations. Some Sony BMG employees also tried to hide payments to station employees by recording them as prizes to non-existent contest winners, the attorney general said.

Investigators disclosed letters and e-mail messages showing the kinds of payoffs at issue. In a letter dated Feb. 6, 2003, a promotions executive lists songs that the company wants played and payment terms for each such “add” to a station’s playlist. “We will continue to send you a weekly ‘priority’ sheet that will direct you and your staff accordingly,” the executive writes. “An add shall be defined, and payment will only be generated, after a station has spun a song for 56 times in a 4 week period, in the 6 a.m. to 12 midnight daypart.”

In an e-mail sent in January 2003, an irate promotions employee instructs a colleague to withhold a free trip, known as a “flyaway,” from stations that bury Celine Dion’s “I Drove all Night” in its overnight rotation of songs. Written all in capital letters, it read:

“OK, HERE IT IS IN BLACK AND WHITE AND IT’S SERIOUS: IF A RADIO STATION GOT A FLYAWAY TO A CELINE SHOW IN LAS VEGAS FOR THE ADD, AND THEY’RE PLAYING THE SONG ALL IN OVERNIGHTS, THEY ARE NOT GETTING THE FLYAWAY. PLEASE FIX THE OVERNIGHT ROTATIONS IMMEDIATELY.”

Soon after the attorney general’s office began its investigation, Sony BMG started reining in such promotional tactics, and it said today that it would not only stop paying for airplay but would disclose any expensive gifts from now on. The company will hire a compliance officer to monitor its progress and to create a system for detecting abuses.

Ann Chaitovitz, director of sound recordings for the American Federation of Television and Radio Artists, said in a statement that the federation thanked Mr. Spitzer “for examining this pernicious issue” and that “pay-for-play hurts both recording artists and the public.” She added: “We look forward to his continuing investigation of the other record labels.”

'Enemies of humanity' quote raises Iraq PR questions – Jul 24, 2005

CNN.com – News release quotes from unidentified Iraqis are virtually the same

Sunday, July 24, 2005; Posted: 5:13 p.m. EDT (21:13 GMT)

BAGHDAD, Iraq (CNN) — The U.S. military on Sunday said it was looking into how virtually identical quotations ended up in two of its news releases about different insurgent attacks.

Following a car bombing in Baghdad on Sunday, the U.S. military issued a statement with a quotation attributed to an unidentified Iraqi that was virtually identical to a quote reacting to an attack on July 13.

After questioning by news media, the military released the statement without the quotation.

Lt. Col. Clifford Kent, spokesman for the U.S. Army’s 3rd Infantry Division, said use of the quote was an “administrative error.” He said the military was looking into the matter.

The car bomb killed 25 people and wounded 33 others near the al-Rashad police station, Baghdad emergency police said. (Full story)

A statement about the attack by Task Force Baghdad 3rd Infantry Division contained a three-sentence quote attributed to an unidentified Iraqi. The statement said the Iraqi called the attackers “enemies of humanity” and vowed to “take the fight to the terrorists.”

The quote was virtually the same as a quote contained in a Task Force Baghdad 3rd Infantry Division statement released after a car bombing on July 13. That attack killed several children.

The statement about the July 13 attack quoted an unidentified Iraqi saying terrorists were attacking “the children.” In Sunday’s quote, an unidentified Iraqi said terrorists were attacking “the ISF” (Iraqi Security Forces).

Following are the two quotes as provided by the U.S. military in news releases:

Sunday’s news release said: “‘The terrorists are attacking the infrastructure, the ISF and all of Iraq. They are enemies of humanity without religion or any sort of ethics. They have attacked my community today and I will now take the fight to the terrorists,’ said one Iraqi man who preferred not to be identified.”

The July 13 news release said: “‘The terrorists are attacking the infrastructure, the children and all of Iraq,’ said one Iraqi man who preferred not to be identified. ‘They are enemies of humanity without religion or any sort of ethics. They have attacked my community today and I will now take the fight to the terrorists.'”

CNN’s Cal Perry and Kevin Flower contributed to this report.

Dozens of Chemicals Found in Most Americans' Bodies

July 22, 2005 Los Angeles Times
July 22, 2005

The concentration is especially high in children, a national study says. But experts aren’t sure what the health effects are.

By Marla Cone, Times Staff Writer

In the largest study of chemical exposure ever conducted on human beings, the U.S. Centers for Disease Control and Prevention reported Thursday that most American children and adults were carrying in their bodies dozens of pesticides and toxic compounds used in consumer products, many of them linked to potential health threats.

The report documented bigger doses in children than in adults of many chemicals, including some pyrethroids, which are in virtually every household pesticide, and phthalates, which are found in nail polish and other beauty products as well as in soft plastics.

The CDC’s director, Dr. Julie L. Gerberding, called the national exposure report ó the third in an assessment that is released biennially ó a breakthrough that would help public health officials home in on the most important compounds to which Americans are routinely exposed.

The latest installment, which looked for 148 toxic compounds in the urine and blood of about 2,400 people age 6 and older in 2000 and 2001, is “the largest and most comprehensive report of its kind ever released anywhere by anyone,” Gerberding said. Findings were broken down by age group and race.

At Thursday’s news conference, CDC officials emphasized the good news: Steep declines were found in children’s exposure to lead and secondhand cigarette smoke.

Lead levels in children have dropped significantly over several years, which Gerberding called an “astonishing public health achievement” attributable largely to its removal from gasoline and paint.

About 1.6% of young children tested from 1999 to 2002 had elevated levels of lead, which could lower their intelligence and damage their brains, compared with 88.2% in the late 1970s and 4.4% in the early 1990s.

But the discovery of more than 100 other substances in humans, particularly children, distressed environmental health experts.

“The report in general shows that people ó kids and adults ó are exposed to things that aren’t intended to be in their body,” said Dr. Jerome A. Paulson, an associate professor of pediatrics at the George Washington University School of Medicine and Health Sciences who specializes in children’s environmental health. “In and of itself, that is a concern. Whether it’s harmful or not we can’t tell from this particular study.”

The new data in the 475-page report reveal how “we have fouled our own nest,” Paulson said. “We contaminated the environment sufficiently that there are measurable amounts of potentially toxic substances in people ó kids and adults.”

The CDC did not try to gauge the health threat the chemicals might pose. A measurable amount of a compound in a person’s body does not mean it causes disease or other damage, the agency noted.

For many compounds in the report, experts have little information on what amounts may be harmful or what they may do in combination.

“We are really at the beginning of a very complicated journey to understand the thousands of substances we are exposed to,” said Thomas Burke, associate professor at the Johns Hopkins Bloomberg School of Public Health.

The discovery of pyrethroids in most people is especially important, as no one had looked for them in the human body before. Pyrethroids are synthetic versions of natural compounds found in flowers, and they have been considered safer than older pesticides, such as DDT and chlordane, that build up in the environment and have been banned in the United States.

But in high doses, pyrethroids are toxic to the nervous system. They are the second most common class of pesticides that result in poisoning. At low doses, they might alter hormones. The compounds are used in large volumes in farm and household pesticides and are sprayed by public agencies to kill mosquitoes.

Pyrethroids “were a step forward [from DDT and other banned pesticides], but now we’re beginning to understand that while they don’t persist in the environment, many of us are exposed,” Burke said. “We don’t quite know what those levels mean.”

Eleven of 12 phthalates tested were higher in children than adults. All of the phthalates but one are used in fragrances. In animal tests, and in one recent study of human babies, some of the compounds have been shown to alter male reproductive organs or to feminize hormones.

Representatives of the chemical and pesticide industries praised the study, saying that human biomonitoring is the best available tool to measure exposure. They echoed the CDC in saying that discovery of the chemicals in the human body did not automatically mean they posed a threat.

The report demonstrates “that exposure to these man-made and natural substances is extremely low,” said American Chemistry Council spokesman Chris VandenHeuvel.

The CDC’s Gerberding said that “for the vast majority” of the 148 chemicals in the report, “we have no evidence of health effects.”

Many toxicologists and environmental scientists disagree.

Studies of animals, and in some cases people, suggest that most of the compounds can affect the brain, hormones, reproductive system or the immune system, or that they are linked to cancer. “These are some bad actors,” Burke said.

Many of the compounds have not been studied sufficiently to know what happens with chronic exposure to low doses. “No evidence of health effects does not imply that they are not harmful,” Paulson said. “It just means we don’t know one way or another.”

Environmental groups have called for U.S. law to require chemical companies to test industrial compounds more comprehensively, a proposal similar to one that the European Parliament is to debate in the fall.

The evidence that many contaminants amass in children more than in adults could mean that they are exposed to larger amounts ó perhaps from crawling, breathing more rapidly or putting items in their mouths ó or that their bodies are less able to cope with or metabolize them.

In the womb and in the first two years after birth, children undergo extraordinary cell growth, from brain neurons to immune cells, so there are more opportunities for toxic compounds to disrupt the cells, Paulson said. Animal tests show that fetuses and newborns are the most susceptible to harm from many chemicals.

In the CDC study, one of every 18 women of childbearing age, or 5.7%, had mercury that exceeded the level that the U.S. Environmental Protection Agency deemed safe to a developing fetus.

Tests on schoolchildren show that mercury exposure in the womb can lower IQs, with memory and vocabulary particularly impaired.

The CDC plans to expand the national chemical report to more than 300 compounds in two years and about 500 in four years. An estimated 80,000 chemicals are in commercial use today.
