Dozens of Chemicals Found in Most Americans' Bodies
The concentration is especially high in children, a national study
says. But experts aren't sure what the health effects are.

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 — the third in an assessment that is released
biennially — 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 — kids and adults — 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 — 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 — perhaps
from crawling, breathing more rapidly or putting items in their mouths
— 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.

I drink a bottle of chemicals every night.
I've got a glass of chemicals sitting right here by my keyboard. Some of the
chemicals in my glass are toxic. L'Chaim!

Even as we type I am separated from some very toxic chemicals by a
thin sheet of glass. Out in my kitchen my oven is getting ready to
change the chemicals in some fish into other chemicals. While I wait I
am going to heat some dihydrogen monoxide and use it (in a form which
will destroy skin if it comes in contact with your hands) to extract
some chemicals from the contents of a little paper bag. I will then
add a mixture of emulsified oils and dissolved sugars, plus a quantity
of ASPARTAME, one of the deadliest chemicals known to man (only
exceeded by Ritalin and Prozac, I believe).
If I am not here tomorrow, please make a donation to Amnesty
International instead of sending flowers to the funeral.

Actually I was poking fun at the lazy way you/they referred to "chemicals"
rather than "dangerous chemicals". These days it's got to the point that
everyone is scared of anything containing "chemicals" even if those
chemicals turn out to be water or vitamins.
Looks what's happened to children's chemistry sets. Years ago they contained
interesting experiments and yes chemicals. Now they contain cookery
ingredients and the sellers get arrested..

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 — the third in an assessment that is released
biennially — 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 — kids and adults — 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 — 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 — perhaps
from crawling, breathing more rapidly or putting items in their mouths
— 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.

Dozens of Chemicals Found in Most Americans' Bodies
I drink a bottle of chemicals every night.
Don't guess you wanted to see want your beloved CDC has to say.
Actually I was poking fun at the lazy way you/they referred to "chemicals"
rather than "dangerous chemicals".
|
I see so you admit you are her to poke fun.
There was nothing *lazy* in my post.
Mercury is indeed a VERY dangerous chemical.
I know as I had mercury poisoning from *mercury amalgams*
much *poking of fun* has been done here of that also.
Those who are here to *poke fun* have a problem.
These days it's got to the point that
| Quote: | everyone is scared of anything containing "chemicals" even if those
chemicals turn out to be water or vitamins.
Looks what's happened to children's chemistry sets. Years ago they
contained
interesting experiments and yes chemicals. Now they contain cookery
ingredients and the sellers get arrested..

Dozens of Chemicals Found in Most Americans' Bodies
I drink a bottle of chemicals every night.
I've got a glass of chemicals sitting right here by my keyboard. Some of
the
chemicals in my glass are toxic. L'Chaim!
Even as we type I am separated from some very toxic chemicals by a
thin sheet of glass. Out in my kitchen my oven is getting ready to
change the chemicals in some fish into other chemicals. While I wait I
am going to heat some dihydrogen monoxide and use it (in a form which
will destroy skin if it comes in contact with your hands) to extract
some chemicals from the contents of a little paper bag. I will then
add a mixture of emulsified oils and dissolved sugars, plus a quantity
of ASPARTAME, one of the deadliest chemicals known to man (only
exceeded by Ritalin and Prozac, I believe).
If I am not here tomorrow, please make a donation to Amnesty
International instead of sending flowers to the funeral.

Try thousands including water, glucose and other sugars, DNA (46
chromosomes), RNA, thousands of different proteins, lipids, small molecules
like thyroid hormones, steroid hormones, adrenaline and other
neurotransmitters.

I wish that some of these Lyme fanatics and anti-psych folks would not
cross-post so much to the nurse group.
