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.

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.

Herbicides May Complicate Pregnancies

A Midwest researcher has found that the combination of chemicals in
some common weed killers may threaten human fetuses. The Great Lakes
Radio Consortium’s Chuck Quirmbach reports:


Warren Porter is an environmental toxicologist at the University of
Wisconsin – Madison. He says he went to the hardware store and bought
common herbicides containing the chemical compounds 2-4-d, dicamba, and
mecoprop. Porter diluted the mixture with water and fed it many times
to hundreds of lab mice. Porter says the mice experienced a 20 percent
increase in failed pregnancies and he contends exposure to the
combination of chemicals is to blame. He says government regulators
often test only individual chemicals and don’t realize how chemical
mixes might affect a living cell.


“It’s like a molecular bull in a china shop. It’s almost impossible to
predict in advance all the possible things they might do.”


Porter says exposure to the mix of weed killer chemicals can also
threaten human pregnancies. But other researchers say the risk to most
people is very low.

Treated Lumber a Health Hazard?

A just-released study by two environmental groups has found high levels of arsenic on the surface of pressure-treated wood products. The Environmental Working Group and the Healthy Building Network tested pressure-treated wood purchased from home improvement stores in 13 cities. In releasing their findings, the groups are calling for a ban on the use of the lumber in construction. Their findings add to the growing concern about the safety of the chemicals used to treat this wood. Those chemicals are now being re-evaluated by both the Canadian and American governments. But as the Great Lakes Radio Consortium’s Karen Kelly reports, the two governments are approaching the issue differently:

A just released study by two environmental groups has found high levels of arsenic on the surface of pressure-treated wood products. The Environmental Working Group and the Healthy Building Network tested pressure-treated wood purchased from home improvement stores in 13 cities. In releasing their findings, the groups are calling for a ban on the use of the lumber in construction. Their findings add to the growing concern about the safety of the chemicals used to treat this wood. Those chemicals are now being re-evaluated by both the Canadian and American governments. But as the Great Lakes Radio Consortium’s Karen Kelly reports, the two governments are approaching the issue differently.


For years, Don Houston at the Canadian Institute of Child Health has been calling for warning labels on pressure-treated wood. The lumber is used in playground structures and picnic tables throughout North America. And it’s treated with a preservative called Chromated Copper Arsenate, which protects the wood from insects and fungi. The preservative is made from arsenic, chromium and copper. And Houston says children who are exposed to the wood may be exposed to those chemicals, as well.


“It’s not just children’s play structures. I’d rather suspect even more problematic is the deck that’s on the back of their house because often times children spend more time there. It’s all sorts of structures that are put in outdoors – decks, balconies, retaining walls; even the telephone pole that might be in a schoolyard might be problematic.”


Houston says the problem arises when arsenic and chromium, which are both carcinogens, remain on the surface of the wood. A study of ten playgrounds conducted by Health Canada in the late 1980’s detected both substances on the surface of play structures made with pressure treated wood. Arsenic and chromium were also found in the nearby soil. Health Canada warns people who work with pressure-treated wood to wear gloves and a mask and to thoroughly wash clothing and exposed skin once they’re finished. The agency also warns against burning pressure treated wood. But Houston says there are still no guidelines for children.


“It doesn’t make a lot of sense for the guy who’s building it to use gloves and then the child ten minutes after it’s built to be walking over it and running on it barefoot and having greater potential health impact from the exposure.”


But scientists at Health Canada say the research findings have been mixed. They point to studies conducted by the U.S. EPA in the late 1980’s that found minimal health risks. Now, fifteen years since they last evaluated these chemicals, both Health Canada and the EPA are taking another look. The update is required by law in both countries. Richard Martin is a toxicologist at Health Canada’s Pest Management Regulatory Agency. He says the presence of arsenic is not always a cause for concern.


“Although there’s a number of reports out there of arsenic being found in soil, and although they’re useful, arsenic is found in all soil. So we need to go the extra step to determine to what extent there’s potential for exposure to children and that type of thing.”


Martin says his agency is reviewing research to determine the effect of exposure on both adults who work with cca-treated wood and children who play near it. But the U.S. Environmental Protection Agency is taking the review a step further. Jim Jones, the deputy director of the EPA’s office of pesticide programs, says they’re concentrating on the exposure to children first.


“It was the children’s exposure through cca-treated wood we think are the most important to look at as they’re the group in the population that is likely to have the greatest exposures, just because of the way in which they interact with playground equipment and on decks.”


The EPA also plans to take soil samples near cca-treated wood structures in 75 playgrounds around the United States. And it’s considering a recommendation that people apply sealants to pressure-treated wood in the interim. The EPA’s scientific advisory panel suggested the agency take that measure. The EPA and Health Canada are collaborating on the re-evaluation – sharing their findings and their recommendations. Don Houston of the Canadian Institute of Child Health hopes that will lead to legislation in both countries that will restrict the use of this lumber in places where children play. The EPA and Health Canada are expected to announce their recommendations next spring.

Educating Parents About Mercury

Over the years, parents have become more aware of the dangers
in their own homes. So they keep kids away from things like pesticides,
electrical cords, and plastic bags. Still, most people remain unaware of
another threat from a common household item. Ironically, it may be the
first thing you reach for when your child is sick. The Great Lakes Radio

Pesticide Links to Parkinson’s Disease

Parkinson’s Disease has been in the news a lot recently ever since
actor Michael J. Fox announced that he’s a victim of the disease.
Scientist have been studying Parkinson’s for years, but still haven’t
