You have flame retardant chemicals in your body. They’re toxic. Americans have the highest levels of anyone in the world. The chemicals are in the dust in our homes and offices and schools. And they’re showing up in our food. In the second of our five part series… Rebecca Williams takes a look at what these exposures might mean for our health:

They’re called PBDEs. That’s polybrominated diphenyl ethers. They help keep foam and plastics from catching on fire.

They are absolutely everywhere.

They’re in your car. They’re in your couch, your office chair, your TV, your drapes, the padding beneath your carpet, your hair dryer, your cell phone. The problem is, they don’t stay put. They leach out of products and they get into us. They’re in dust and soil and the wastewater sludge that’s spread on farm fields.
The chemicals are in fish and meat and dairy. They’ve been found in the Arctic and Antarctic. They’re in peregrine falcons and killer whales and polar bears and salmon. They’re in cats and dogs.

Babies come into the world with flame retardant chemicals in their bodies.

The chemicals have also been turning up in breast milk.

Six years ago, Meredith Buhalis had her breast milk tested as part of a study of new moms. And PBDEs turned up.

“I had a brief moment of oh my gosh, ew, that’s terrible!”

Her levels were not much above the average American. And she says she kept nursing her baby because it was the best thing for her. But it did make her think.

“I guess I just thought proactively after that we need more legislation and research about what these chemicals do and how we can control the ways they get into our bodies.”

Scientists and doctors are worried because hundreds of peer-reviewed studies are suggesting links to problems with brain development, changes to thyroid systems, and fertility problems.

“If you’re looking at developmental exposure then these are very toxic chemicals.”

Linda Birnbaum is the director of the National Institute of Environmental Health Sciences. She studies the health effects of flame retardants. She says there are hundreds of studies in animals showing negative effects from PBDEs. Now, human studies are coming out.

“Depending how high they were exposed in utero we’re seeing associations with some lower IQ and some behavioral deficits. There are also some effects beginning to be reported on other reproductive endpoints in the human population. All of these kinds of effects have been reported in animal studies.”

Birnbaum says the average American has about 30 parts per billion of these flame retardants in his or her body. But some people have levels as high as 10-thousand parts per billion. Those are levels where in animal studies scientists are seeing problems.

One thing the experts say you should keep in mind is that just because you’re exposed to a chemical does not mean you’ll get sick and die.

Dr. Arnold Schecter studies our exposure to flame retardants. He’s a professor at the University of Texas School of Public Health.

“What we’re talking about is not something like cyanide where if you get some in your body you’re going to drop dead immediately. We’re talking about something more like asbestos or cigarette smoking where you have effects on a population basis. 80 % of lung cancers are from smoking but the majority of smokers are not going to get lung cancer so there’s some genetic roll of the dice.”

Dr. Schecter says you really should try to keep your levels as low as you can. But it can be really tough because these chemicals are everywhere. And despite government policies to reduce our exposures, there’s no evidence levels are going down.

Are Flame Retardants Putting Us at Risk? (Part 1)

  • PBDEs are used in a lot of our products, including couches, to make them resistant to flames. (Photo by Fastily from Wikimedia Commons)

Flame retardant chemicals are used in hundreds of products in our homes and offices and schools. The chemicals can slow the spread of fire. But certain kinds of these chemicals leach out of our couches, our TVs, our carpet padding and many other things in our homes. And they’re getting into our bodies. In the first of our five part series… Rebecca Williams tries to find out what’s in the products in her own home:

A few months ago, I never really thought about flame retardants. I knew some of these chemicals were probably in my house, but I kind of just shrugged it off.

But then I had a baby. And that made me want to take another look.

The chemicals I’m talking about are called PBDEs. That’s polybrominated diphenyl ethers.

Some of these PBDEs have been phased out. But there’s a good chance your couch and chairs and carpet padding still have these chemicals in them. You’re probably surrounded by PBDEs and you will be for a long time.

That worries some scientists and doctors. That’s because hundreds of peer-reviewed studies in animals are suggesting exposure to PBDEs might be linked to problems with brain development, changes to thyroid systems, and fertility problems. And recently, human studies are coming out and they’re showing some of the same things. Public health experts are especially worried about babies and young kids because they grow so fast… and they are constantly exposed to dust. That’s where PBDEs tend to collect.

The American Chemistry Council did not want to be recorded for this story. But in an email response to my questions, a spokesperson said:

“Flame retardants have been rigorously tested and have saved lives.”

Two of the big chemical companies also responded to me by email. Chemtura and ICL Industrial Products both say they stand by the safety of their flame retardant chemicals.

But many independent scientists and public health experts say it’s a good idea to reduce your exposure to PBDEs.

So all of this made me wonder. How can we know what’s in the stuff we buy? It seems like a simple question. But there are no labels at the store.

You can write to the companies that make your furniture and TV. But I wrote to a half dozen companies to ask them about flame retardants… and only heard back from one, Fisher-Price.

But I have a lot of stuff that’s not made by Fisher-Price. So… I thought I’d call in some experts. The guys at the Ecology Center test consumer products for chemicals. Jeff Gearhart volunteered to come up and test my home to see if we could find flame retardants.

(door opening sound)

“Hey, come on in!” “Hello!”

He brought along a device that looks like a little gun. It can tell you the chemical makeup of products.

“We’re going to look at baby products, toys, furniture, some of your flooring… these chemicals can be transported into your carpet, your child crawls on the carpet, they put their hand in their mouth or there’s just dust in the overall environment. So that’s the mechanism of how we get exposed to these chemicals.”

As Jeff went around my house… he found flame retardants in my TV, the padding under the carpet, three chairs, a car seat, a baby play mat, and our cable box. When PBDEs were phased out of furniture, a lot of companies replaced them with other chemicals.

I wanted to find out more about those chemicals. So I cut samples of foam from some things from my house… and sent them to Heather Stapleton. She’s a chemist at Duke University. The sample I sent her from my baby’s changing table pad totally stumped her.

“I was a little bit surprised honestly because we’ve seen most of the major chemical flame retardants in foam products. This one I’ve never seen before. You mentioned this was made in China. So it could be the Chinese companies are using something different than what we use in the United States.”

She couldn’t tell me whether or not it was safe.

She says it’s next to impossible to know what’s in the things you buy. That’s because the federal government doesn’t require companies to reveal the chemicals in their products… or require proof that the chemicals are safe.

Lake Algae and Lou Gehrig’s

There’s a kind of blue and green scum that can bloom in lakes and ponds across the nation. This scum is called cyanobacteria.

There’s a kind of blue and green scum that can bloom in lakes and ponds across the nation. This scum is called cyanobacteria. For years, scientists have known that this stuff can produce dangerous toxins. Amy Quinton reports now researchers are studying whether there’s a link between cyanobacteria and Lou Gehrig’s disease:

Jody Conner reaches into his refrigerator in his lab.

“This is the cyanobacteria that we’ve collected. This one comes from Harvey Lake. See how green that sample is?”

He’s the Director of New Hampshire’s Limnology Center.

Conner has been collecting samples of cyanobacteria from lakes across New Hampshire.

It looks like green scummy algae on the surface of the water that can be several inches thick.

But it’s actually bacteria.

Conner says cyanobacteria feed on nutrients like phosphorus and nitrogen that can come from runoff of lawn fertilizers or sewage.

“They need sunlight, phosphorus, and they seem to like the warmer waters. So, they really grow in mass numbers when they have all three of those.”

Jim Haney is a professor of biological sciences at the University of New Hampshire.

He says, in high enough concentrations, some cyanobacteria blooms can produce more than 70 different kind of liver toxins called microcystins.

“That scum can be toxic enough that it’s been estimated that only about 17 milliliters is enough to kill a small child. 17 milliliters is just a couple of teaspoons.”

Cyanobacteria blooms can also produce neurotoxins.

Haney, and other researchers, have embarked on research to find out if there’s a connection between cyanobacteria and patient’s with Lou Gherig’s disease – also known as ALS.

The research began when Doctor Elijah Stommel began mapping hundreds of ALS patients across New Hampshire.

Stommel is a neurologist at Dartmouth Hitchcock Medical Center.

He noticed the incidence of ALS was 2.5 times greater than the national rate around lakes known to have had significant cyanobacteria blooms.

Stommel says he found a particularly high cluster of patients on one lake in the western part of the state.

“We were able to establish that there appeared to be about a 25 fold increase in what one would expect to see for the ALS incidence.”

But he’s not sure if cyanobacteria are the culprit.

A few scientific studies have shown a particular type of neurotoxin found in cyanobacteria is also found in patients with ALS.

The neurotoxin is known as BMAA.

But it’s not known whether BMAA can trigger ALS.

Jim Haney says more research is needed.

“We know that, in the laboratory, a wide range of different types of cyanobacteria are able to produce BMAA. So, one of our goals this summer is to determine whether there are BMAA molecules in our lakes.”

So far, researchers haven’t found BMAA, and there are still a lot of unknowns about how people could be exposed.

Do you have to drink it or can you breathe it in the air?
How long do you need to be exposed to it before it causes damage?

Again, Doctor Elijah Stommel.

“If there is a link between cyanobacteria blooms and the toxins they make, and a neurodegenerative disease like ALS, then I think we should pursue that with as much vigor as we can. And I think the neurology literature would suggest there is an environmental trigger for ALS.”

But, scientists have not yet found that link.

If they do, Stommel says that link might help find ways to prevent the dangerous toxins, or block their effects.

Many Household Chemicals Not Tested

Two government agencies are agreeing to work together to test chemicals in products we use. But Lester Graham reports… there are still lots of hurdles and years of delays before products already on the shelves can be tested for safety:

Two government agencies are agreeing to work together to test chemicals in products we use. But Lester Graham reports… there are still lots of hurdles and years of delays before products already on the shelves can be tested for safety:


Three years ago, a government report showed the U.S. Environmental Protection Agency could not assess the health risks of 85% of the chemicals in the products you probably have in your bathroom or out in the garage.

The Government Accountability Office found part of the reason then, and now, was because laws protect corporations’ secrets—over public knowledge about health risks.


On top of that other reports found the EPA was years behind in testing chemicals at all.


Now the EPA and the National Institutes of Health are going to be working together to test chemicals faster and without using lab animals.


The agencies will be testing the safety of chemicals ranging from pesticides to household cleaners to see if they harm human health.


The one problem… it will take, quote, “many years” to validate the new testing methods before the testing program can be fully implemented.

For the Environment Report, this is Lester Graham.

A lot of studies have linked air pollution with heart and lung
problems. A new study suggests your diet can worsen air pollution’s
effects on you. The Great Lakes Radio Consortium’s Michael Leland
has more:


Every time you inhale, you’re breathing in tiny particles from dust, soot
and smoke. They can increase both the plaque buildup in your arteries,
and the risk of a heart attack or stroke.


Now, a study led by Dr. Lung Chi Chen at New York University’s
School of Medicine says a high fat diet combined with bad air led to a
faster buildup of plaque in the arteries of mice. He says that’s because
air pollution affects lipids – fats – in the blood. It changes their
characteristics, or oxidizes them, which leads to more plaque on artery
walls.


“If the mice are fed with high-fat, then the level of the oxidized
lipid will be higher, because they have more lipid in their blood.”


Dr. Chen says arteries of mice on a high-fat diet and breathing dirty air
were 42-percent blocked. Mice breathing clean air had arteries that were
26-percent blocked.


He hopes the study not only encourages people to eat better, but also
persuades the government to toughen air quality standards.

Study: Air Pollution Affects Birth Weight

Cars, trucks, and coal-fired power plants contribute to fine particle pollution, or soot. That type of pollution can be harmful for adults with heart or lung problems, and kids with asthma. A new study suggests that the pollution can also affect developing babies. The Great Lakes Radio Consortium’s Rebecca Williams has more:


This study was the first to look at fine particle pollution and developing babies in the U.S. Researchers looked at more than 18,000 babies that were carried to full term in California. They found that mothers living in areas of high exposure to fine particles had babies that weighed about an ounce less than mothers living in low exposure areas.


Tracey Woodruff is a senior scientist with the Environmental Protection Agency. She co-authored the study in the journal Pediatrics. Woodruff says an ounce is a small difference in birth weight, but it’s significant enough to merit more research on particulate matter – also known as “p.m.”


“This is one more piece of information about adverse health effects of p.m., which is feeding into the larger literature, which is leading EPA to embark on a number of different activities to try to reduce the levels.”


Woodruff says future research should look at whether fine particle pollution is related to premature births.

Fire Retardant Chemicals Ring Alarm Bells

Flame retardant chemicals help make our lives safer.
The chemicals are designed to keep plastics and foam from
catching on fire, but the flame retardants are worrying some
scientists because these chemicals are turning up in people’s
bodies, sometimes at alarmingly high rates. The Great Lakes

Flame retardant chemicals help make our lives safer. The chemicals are designed
to keep plastics and foam from catching on fire. But the flame retardants are
beginning to worry some scientists because these chemicals are turning up in
peoples’ bodies. Sometimes at alarmingly high rates. The Great Lakes Radio
Consortium’s Mark Brush has more:


If you take a look around your house, you can find a lot of things that have
flame retardant chemicals in them. They’re in your television set, the cushions
in your couch, and the padding underneath your carpet. They’re known as poly-bromiated-diphenyl
ethers, or PBDEs. And they’re either mixed in or sprayed on plastics and foam to keep a fire
from spreading.


Five years ago a Swedish study found these chemicals were accumulating in women’s breast
milk. Studies in the U.S. followed, and researchers also found PBDEs in Americans, but at
even higher levels. In fact, Americans have some of the highest levels ever measured. And
over time, the levels have been going up.


(sound of baby)


Meredith Buhalis was one of those people measured in a study by an envrionmental organization
called the Environmental Working Group. Buhalis and 20 other first time moms sent in samples
of their breast milk. When the samples were tested, all of them had some level of PBDEs in
them. Buhalis says when she read the results she didn’t know what to think.


“I guess I kind of read the results and the study was like, ‘Oh, well that sort of sucks.’
I wish I knew more about what that meant. ‘Cause I don’t. You know, they don’t know what
that means.”


Scientists don’t know how or if the chemicals affect human health. And some scientists
think the government and the chemical companies aren’t doing enough to look into PBDEs.


(sound of typing)


In his office at the University of Texas in Dallas, Dr. Arnold Schecter is working on an
article about the flame retardants. He’s been studying toxic chemicals for more than thirty
years. He and some of his colleagues think PBDEs are a lot like another type of chemical…


“It reminds us of PCBs. PCBs structurally are similar to the PBDEs. So there is the worry,
or the concern, that they may have many, if not all, the toxic effect that PCBs have on humans.”


So far the data on PCBs strongly suggest that the chemicals can cause cancer in humans as
well as other human health effects such as damage to the nervous and immune systems. The
companies that manufacture the flame retardants say it’s not fair to compare PBDEs with
PCBs. They say the chemicals are vastly different.


But no one really knows whether the chemicals are similar in the way they affect human
health. That’s because no one’s studied the human health effects of PBDEs.


“Unfortunately, there are no published human health studies and I don’t believe any have
been funded by the federal government to date. Nor by industry, nor by any foundations,
which is a bit different than the situation with PCBs and dioxins years ago when many
studies were being funded.”


Some animal studies suggest that the chemicals can permanently disrupt the hormone and
nervous systems, cause reproductive and developmental damage, and cause cancer. All that
makes scientists such as Dr. Schecter especially concerned about the most vulnerable
population – developing babies.


Because of the concerns, the biggest manufacturer of these chemicals in the U.S. has agreed
to stop making two of the PBDE formulations that were found to accumulate in people. Great
Lakes Chemical says production will stop by the end of this year. The chemicals will be
replaced with another type of brominated flame retardant.


The Bromine Science and Environmental Forum is a trade group that represents companies
that make the flame retardants. Peter O’Toole is the group’s U.S. Director. He says so
far the amount of chemicals found in people doesn’t concern the companies, but the upward
trend does.


“And again, it wasn’t of alarming numbers, but the manufacturer was concerned that these
numbers were going up nonetheless. And they thought it was prudent, and they talked to the
EPA and EPA thought it was prudent if there was some sort of mutual phase out of those materials.”


Dr. Schecter says he commends the company for taking this step. But he says even though these
two formulations will be phased out, the flame retardants are already in our environment now.
He says his research has found high levels of PBDEs by wiping the plastic casing on television
sets, and in the dust found in homes. He says what’s in our homes now isn’t going to vanish,
so we need to figure out how the chemicals get into us, so we can avoid potential health problems.


For its part, the U.S. Envrionmental Protection Agency says large-scale human health studies
take a long time to develop. An agency spokesperson says the EPA first needs to learn how a
person becomes highly exposed. After that, they say researchers will be able to ask the question,
“for the highly exposed people, are there any health effects?”


(sound of baby)


That leaves people such as Meredith Buhalis, with a lot more questions than answers.


“We are thinking of having another baby, and I think I would really like to know more about
PBDEs. I think about it when I think about that.” (to her daughter) “Oh thank you. Hi, baby.
Hi, Zoe.”


The Federal government doesn’t plan to regulate the chemicals anytime soon. But some states
aren’t waiting for more studies. A handful of states have placed restrictions on certain
types of PBDEs. And in other states, legislation is pending.

Researchers in one state in the region are trying to find out how much mercury load
their residents are carrying. So far, 300 samples have been collected for the study.
And the researchers have found that one-quarter of Wisconsin men participating in the
study have high levels of mercury. The
Great Lakes Radio Consortium’s Stephanie Hemphill reports:


The EPA says the safe level for mercury is one part per million. In the ongoing Wisconsin
study, one in four men and one in eight women have more than that in their bodies. The
study subjects volunteered for the study, so officials say they may not represent the
population overall.


Eating fish contaminated with mercury has long been thought to cause developmental
problems in young children. But now there’s research from Europe showing it can also
contribute to heart disease in adult men.


Lynda Knobeloch is a toxicologist with the Wisconsin Department of Health.


“There have been several studies that show that people who eat fish have less heart
disease because of omega 3 fatty acids, but the European study was able to sort out the
good effects of omega 3s from the bad effects of methyl mercury, and see that the mercury
actually can overwhelm the beneficial effects of omega 3s and actually cause heart disease.”


Wisconsin is requiring its utilities to reduce mercury emissions by 75% over ten years.

West Nile Virus Marches West

  • Zoos have helped public health officials monitor the spread of the West Nile virus. Besides concerns about human health, zoos are worried about the birds in their care.

Cooler weather sweeping the Great Lakes region means the end of the mosquito season. It also means a temporary halt to the spread of West Nile virus in the area. But this past summer the virus made headway into the region much faster than experts had expected. The Great Lakes Radio Consortium’s Lester Graham reports:

Cooler weather sweeping the Great Lakes region means the end of the mosquito season. It also means a temporary halt to the spread of West Nile virus in the area. But, this past summer the virus made headway into the region much faster than experts had expected. The Great Lakes Radio Consortium’s Lester Graham reports.


It’s extremely rare that West Nile virus causes severe illness in humans. But it does happen. While most people won’t even realize they’re infected, about one fourth of those infected will exhibit some mild symptoms. However, the virus can cause encephalitis, which is an inflammation of the brain. In very rare cases it can be fatal.


Zoos have been helpful in monitoring the spread of the disease. It was first identified here in the U.S. by the Bronx zoo in the fall of 1999 after crows started dying in the New York area. Since then, zoos across the U-S have kept watch on their birds and animals. In part to protect them and in part to help health officials track the progress of the virus.


Scientists thought the virus would slowly make its way to neighboring states. But, it’s spread much more quickly than expected. It wasn’t supposed to hit states as far west as Illinois and Wisconsin until sometime next year. But it made it even farther west with reports of it in Missouri.


Researchers have learned the virus is carried by birds such as crows, blue jays, hawks and Canada geese. Dominic Travis is a veterinary epidemiologist at the Lincoln Park Zoo in Chicago. He says since West Nile virus infects birds, experts suggested it would spread southward from New York. That’s because many birds, including some infected with the virus would travel south for the winter. Others, though, said it could spread west.


“And, the westward race won. We were fairly surprised that it came past the Michigan and western Ohio area, but we’ve been prepared because we started this surveillance system and started working with the CDC and USDA and everybody last spring for this specific eventuality.”


Travis says zoos across the Midwest started monitoring for West Nile virus this past spring. They worked with local health officials to determine if the disease had spread to birds in the area.


While birds carry the disease, mosquitoes spread it. So, officials at he Lincoln Park Zoo have been trapping mosquitoes and drawing blood from its animals, testing for West Nile virus. They’ve also been working to reduce the chance that animals will be bitten by mosquitoes. Again. Dominic Travis.


“The two strategies are try and limit the mosquito and if you can’t limit the mosquito, limit the contact.”


Most zoos are hesitant to use insecticides to kill the mosquitoes. So, instead, they try to eliminate places where they can breed. Basically, that’s anywhere a puddle of water stands for more than four days. Travis says that helps meet strategy number one, limiting the mosquito.


“So, a) if you don’t have mosquitoes, the risk is fairly low, and b) if you can’t get rid of all your mosquitoes, then you want to stop mosquitoes from biting the animals and so you do things to keep them separate. And those are –depending on the birds, the size, the situation, the zoo– those are keeping them in during mosquito feeding hours or some people have mosquito nets that they’re incorporating and so on and so forth.”


Zoos are especially worried because they’re responsible for some very rare birds, in some cases the last of a species.


At the Saint Louis Zoo, a huge outdoor flight cage and several other outdoor cages make up the zoo’s bird garden. Zookeeper Frank Fischer says outside bird exhibits are at highest risk.


“We’re making sure that, trying to make sure that none of our birds, even the birds in the outside exhibits here in the bird garden don’t contract any of that disease, say, from crows or our blue jays or birds of that type.”


While birds are most at risk of infection, they’re not the only species hit by the virus. In the U.S., as many as a dozen people have died after being bitten by a mosquito carrying West Nile virus. And even more horses have died. People and horses are considered incidental victims. That is, they don’t carry the disease and they don’t spread it. But they can be infected. A veterinarian in southwestern Illinois, Don Van Walleghen, says he’s gotten a lot of calls from worried customers, asking about West Nile virus.


“Basically, they want to know, is it here? Is it a concern for me?”


And because it’s such a recent phenomenon Van Walleghen’s customers have a lot of other questions. They bring in dead birds, wondering if their dog or cat that was playing with the bird might be infected. So far, aside from horses and people, there have been no reports of other animals, livestock or pets, being infected by West Nile virus, or spreading it.


“In humans, if you are a human bitten by a mosquito that had this disease, you could not transmit it to your kids or to anything else. So, at least that limits the disease from even being thought of as any kind of epidemic.”


But it is spreading. Experts hope that weather conditions next year are not good for mosquito production. But even a relatively normal to dry season as this past year was has not seemed to slow the spread of West Nile virus. If next year is wetter, experts say the virus could spread farther and infection rates could rise. That’s why health and agriculture experts are reminding people to work toward reducing the mosquito population next year. They recommend everything from keeping roof gutters unclogged to prevent standing water, to landscaping yards and driveways to eliminate puddles. Anything that will slow mosquito production next year will hopefully slow the spread of the West Nile virus. For the Great Lakes Radio Consortium, this is Lester Graham.
