Flame retardant chemicals help keep foam and plastics from catching on fire. But certain kinds of these chemicals are building up in people. And hundreds of studies are suggesting links to problems with brain development, and thyroid and fertility problems. In the final part of our five part series… Rebecca Williams reports on the alternatives to these chemicals:

PBDEs – or polybrominated diphenyl ethers – are flame retardant chemicals. Penta-BDE is a type that was the go-to chemical for furniture for more than 30 years. Penta was phased out in 2005 because of health concerns. So companies needed alternatives. Now they often use a chemical called chlorinated tris. But there’s a problem.

“Chlorinated tris was removed from children’s sleepwear in the 70s after it was shown to cause mutations and cancer in animals.”

Arlene Blum is one of the scientists who discovered the chemical could mutate DNA. She also discovered the chemical was being absorbed into children’s bodies when they wore their pjs.

“It’s now being used as the flame retardant in furniture and baby product foam across the U.S.”

Blum is a chemist at the University of California Berkeley. She recently published a peer-reviewed study in the journal Environmental Science & Technology. She and her team found chlorinated tris in furniture. And they also found it’s migrating out of products and getting into house dust. And then there are other newer flame retardants.

“The other main substitute is called Firemaster. It’s a mixture of four chemicals, two of which are known to be toxic and two of which we don’t know too much about.”

None of the three big chemical companies wanted to be recorded. One of the companies, Albemarle, didn’t respond at all. Both Chemtura and ICL Industrial Products said in email statements that their flame retardant chemicals are extensively studied and safe.

Furniture companies say they’re in a bind. There’s a California regulation called Technical Bulletin 117. It requires the foam in upholstered furniture and baby products to meet a certain fire standard. And that usually means companies have to add flame retardants to the foam to meet the standard. Companies often don’t want to make separate products just for California, so they just treat everything with flame retardants.

Andy Counts is CEO of the American Home Furnishings Alliance. He says back when they were using penta-BDE… they were told it was safe. And they believed it was. Now, he says furniture makers are switching to new chemicals. They’re being told those are safe. And they believe they are.

“Certainly when we started using penta years ago there was no indication of any harmful effects. So it’s always a danger to use substitutes unless you have all the science in front of you. We feel confident that we have that. But as a furniture manufacturer we would like to avoid any questions about the safety of our products.”

At the same time, a handful of companies have moved away from PBDEs and other suspect flame retardants altogether.

Arlene Blum says it’s a good idea to reduce your exposure to those flame retardants. She says they migrate out of products and get into dust.

“You just want to be really good about keeping dust down in your house. Do a lot of vacuuming with a HEPA filter, wet mopping and then always washing your hands before you eat.”

She says one rule of thumb is to look for the little white label on furniture and baby products with foam in them that says it meets California TB 117… and then avoid buying that stuff if you can.

She says we will all probably be surrounded by PBDEs in our homes for decades.

The hope is this new generation of flame retardants will be safe. But there’s no government standard to guarantee that.

Flame retardant chemicals are added to hundreds of products in our homes and offices to slow the spread of fire. But during a fire, the fumes can cause problems for firefighters.

Flame retardant chemicals are added to hundreds of products in our homes and offices to slow the spread of fire. But during a fire, the fumes can cause problems for firefighters. In the fourth part of our five part series, Rebecca Williams reports… some firefighters say flame retardants can make their jobs more dangerous:

We started using flame retardant chemicals called PBDEs back in the 1970s. Ever since, some people say firefighting has gotten more complicated.

Kathleen Chamberlain is the Fire Marshall for the city of Ann Arbor, Michigan.

“In certain ways, I’m sure the flame retardant chemicals have made things easier: they’ve delayed fires, they’ve slowed them down.”

That’s the upside. But she says there’s also a downside.

“They’ve added a toxicity level which has made things much more dangerous for everybody.”

(fire station radio: “Battalion 1-3… “ and truck noise)

Downstairs at the fire house… Captain Tim Flack has to be ready to jump into his equipment at a moment’s notice. These days, on the way to the fire, he straps on air tanks and gets ready to put on his mask.

“You had the tough man mentality back in the old days where they didn’t wear the air packs and stuff like that. It’s to your benefit to wear your air packs and breathe the good air and not be the tough guy.”

He says all firefighters wear their air packs these days. It’s required. Turns out it’s also a really good idea.

Many firefighters are concerned about flame retardants called PBDEs. Even though two kinds of PBDEs were phased out by manufacturers several years ago, their products are still in our homes. The International Association of Firefighters says when PBDEs burn they release dense fumes and black smoke. And a highly corrosive gas called hydrogen bromide.

You wouldn’t want to breathe it.

So, firefighters are in a tricky place. Many say flame retardant chemicals are a good idea. But they want to move away from brominated flame retardants such as PBDEs. They say there are alternatives.

It’s complicated by a California regulation. Technical Bulletin 117 requires the foam in upholstered furniture and baby products to meet a certain combustion standard. And that often means companies have to add flame retardants to the foam to meet the standard.

The chemical industry stands by the safety of its flame retardants. The American Chemistry Council did not want to be recorded for this story. But in an email statement, the Council said quote: Flame retardants have been credited with saving many lives including the passengers and crew of the 2005 Air France crash in Toronto.

Many people say there are situations, such as airplane fires, where flame retardant chemicals can buy precious seconds to help people escape.

But many firefighters say in our homes, it would be smarter to deal with the sources of ignition.

Cigarettes and other smoking materials are the leading cause of fire-related deaths in the U.S. But for years, the tobacco industry fought laws requiring self-extinguishing cigarettes.

A 2008 Washington Post investigation revealed the tobacco industry and the flame retardant industry have a lobbyist in common. That lobbyist, Peter Sparber, first helped the tobacco industry fight against self-extinguishing cigarettes. Then he lobbied for tighter regulations that would require the use of flame retardant chemicals in furniture.

So first, he lobbied to protect the cause of many fires. Then he lobbied to use chemicals to retard those fires.

These days, most states now have laws requiring cigarettes to be self extinguishing.

Firefighters’ groups are joining forces to stop the use of PBDEs and other brominated flame retardants altogether. But one of the major chemical companies, ICL Industrial Products, says brominated flame retardants are the most efficient at putting out fires… and they will continue to play a vital role in product designs and public safety.

Flame retardant chemicals are in many of the products we use. They help slow the spread of fire. But some kinds of these chemicals are building up in people and in pets and wildlife. And hundreds of studies are suggesting the chemicals could be linked to problems with brain development, and thyroid and fertility problems. In the third part of our five part series… Rebecca Williams takes a look at why our federal government has not banned them:

In the U.S., chemicals are innocent until proven guilty.

Companies don’t have to prove chemicals are safe before putting them on the market. If government officials want to ban a chemical, they have to prove it’s harmful.

There are flame retardants called PBDEs – or polybrominated diphenyl ethers. There’s a good chance they’re in your couch or office chair or carpet padding. They’re toxic. Pretty much every American has some level of PBDEs in their body. The European Union has banned three kinds of PBDEs. Several U.S. states have banned them. But even people who want the federal government to ban them say we can’t.

“The EPA does not have the power or authority to ban these chemicals.”

Mike Shriberg is with the Ecology Center. It’s an environmental group.

“The last time EPA tried to take significant action against a chemical was on asbestos. A chemical that is widely known to cause cancer. And the agency’s actions were overturned in court essentially saying they lacked the authority to ban even this extremely well known hazardous chemical.”

Our nation’s chemical law is called the Toxic Substances Control Act. It’s supposed to give the Environmental Protection Agency power to regulate chemicals.

The EPA did not want to be recorded for this story. But in an email statement, a spokesperson said the agency can ban chemicals under the Act. But it has to prove they present an unreasonable risk. And the spokesperson said quote,

“Flame retardants are particularly challenging to make this finding because their commercial benefit is they save lives in fire situations.”

Some people say the EPA’s hands are tied. Deborah Rice is a toxicologist with the Maine Center for Disease Control. She says the chemical industry made sure of that.

“This Toxic Substances Control Act was passed by Congress over 30 years ago and it had major input by the chemical industry and it hasn’t been reformed since because of major lobbying by the chemical industry. That’s what kept the U.S. unable to really protect the health of its citizens or the environment.”

Rice has direct experience with input by the chemical industry. In 2007, the EPA asked her to chair a panel to help set safe exposure levels for a PBDE flame retardant. The chemical industry felt Rice had expressed bias against the chemical. The industry asked the Bush Administration’s EPA to remove Rice from the panel. The EPA removed her.

To this date, there are no federal bans on any PBDE flame retardant.

The company that made penta-BDE and octa-BDE started voluntarily phasing them out in 2004. EPA just reached an agreement with the three big chemical companies to phase out deca-BDE in three years.

Critics of these kinds of agreements point out they’re just voluntary. The Ecology Center’s Mike Shriberg says the agreements are not binding.

“EPA is essentially forced to begging for a piece of paper that’s meaningless if not followed by the companies. That’s why we’re in this mess we’re in.”

Shriberg says the only way to fix things is to overhaul our nation’s chemical safety laws.

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.

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.

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.

Toxic Flame-Fighter Still in Use

Two forms of a toxic flame retardant
are being phased out by companies or banned
by state laws. But, Lester Graham reports,
a third form is still being used:

The third flame retardant, called Deca-BDE, is still being used in drapes, carpets,
furniture upholstery and the plastic cases of electronics, like your computer.

PBDE’s are being found in fish and wildlife, and even in mothers’ breast milk.
Studies have found they cause developmental problems and liver cancer in
animals. Environmentalists say just like the other two PBDEs, Deca-BDEs should
be banned.

Mike Shriberg is with the Ecology Center.

“There is no reason to have toxic chemicals like this when we’re fighting fires. The
Fire Chiefs Association, the firefighters, they support banning this chemical because
they know there are safer alternatives that keep us just as safe from fires.”

But unlike the other PBDEs, most states have not passed laws to ban deca-BDEs.

New Flame Retardants Show Up in Wildlife

A study of gull eggs shows that more chemicals used as flame retardants are
showing up in the environment. Chuck Quirmbach reports:

Transcript

A study of gull eggs shows that more chemicals used as flame retardants are
showing up in the environment. Chuck Quirmbach reports:


Flame retardants on clothes and other products have reduced deaths and
injuries caused by fires. But the compound traditionally found in retardants,
polybrominated diphenyl ethers, or PBDE, has found its way into many water
bodies and even into women’s breast milk.


A few years ago, after concerns about the compound being linked to health
problems in wildlife, makers of PBDEs began to phase out some types of it. A
recent update of a study of herring gull eggs around the Great Lakes has found
that levels of the phased out chemicals have been dropping, but research
scientist Robert Letcher of Environment Canada says there’s also bad news:


“Flame retardants that are replacing them commercially are starting to show up in
the gulls as an indicator species. And for example, there’s the replacement flame
retardant callled deca-BDE. That’s what we’re seeing going up.”


Letcher says there could be long-term health concerns for both wildlife and
humans.

Pbde Levels Increase in Great Lakes

Transcript

Great Lakes scientists say there’s been some progress made against traditional chemical threats. But researchers say other chemical contaminants are emerging in the lakes. Chuck Quirmbach reports:


Scientists report overall declines in PCB’s, dioxin, and certain pesticides, partly because some of those substances are banned. But one chemical compound apparently on its way up is polybrominated diphenyl ethers, or PBDE’s. They’re used as fire retardants.


Carri Lohse-Hanson is with the Minnesota Pollution Control Agency. She says even though scientists are still trying to learn more about PBDE’s, there should be controls on the chemical.


“I think the preventative approach would be preferable than waiting until we had all the information to figure out if we had to do some kind of reduction.”


Lohse-Hanson says there have been some changes in the use of flame retardants and the phasing out of certain forms of PBDE’s.


The EPA says it still needs to determine the effects of the compound at the levels it’s being found in the environment.

A new study by an environmental group says there are high
concentrations of toxic chemicals called PBDEs and phthalates inside
many cars. The Ecology Center is calling for the chemicals to be phased
out. The Great Lakes Radio Consortium’s Tracy Samilton reports:


PBDEs are used as flame retardants in auto parts, and phthalates make
plastic parts more flexible. The study found that the heat that builds up
inside a car in the sun causes the chemicals to be released, which
increases exposure to humans.


Jeff Gearhart of the Ecology Center says there are plenty of safer
alternatives and the auto industry should use them. He says there are not
many studies on the effect of the chemicals on humans, but animal
studies show that they hurt reproduction and brain development.


“We should take a precautionary approach and we think that’s the
type of approach that many people take in their own lives.”


A spokesperson for the Alliance of Automobile Manufacturers says
flame retardant PBDEs make cars safer for people in the event of a fire,
and that PBDEs and phthalates are both safe.

The chemicals are known as poly-brominated-diphenyl-ethers, or PBDEs.
Scientists already knew that these flame retardant chemicals where found in
food. Now researchers are finding the chemicals, in household dust.


Heather Stapleton is a research chemist at the National Institute of
Standards and Technology. She authored a study recently published by the
American Chemical Society.


“I went out and collected some house dust samples from areas within the
Washington D.C. metropolitan area, and brought these samples back to the lab
and just did a preliminary measurement looking at PBDE’s in the house dust
samples and found surprisingly high levels in the house dust.”


Researchers are most concerned about how the chemicals affect developing
babies. Babies have more contact with household dust than the rest of us.
The chemicals have been found to cause developmental and nervous system
damage in rats and mice.
