toxics

A primer on chemicals, fertility, and reproduction

Illustration: Keri Rosebraugh Feeling unusually infertile lately? You’re not alone: according to a December 2005 report from the U.S. Centers for Disease Control and Prevention, around 12 percent of American couples reported having a hard time conceiving a child and bearing it to term in 2002, up 20 percent from the 6.1 million couples reporting […]

EPA determines coal waste raises cancer risk

The waste from burning coal — coal combustion products, or CCPs, like coal ash and boiler slag — contains toxic heavy metals like mercury and cadmium. But don’t worry, the coal industry says that the concentrations aren’t high enough to do anyone harm. Taking the coal industry’s word for it, the U.S. EPA decided in […]

Washington state caps the cost to pollute, rather than the pollution

The Sightline Institute (formerly Northwest Environment Watch) picks up a Seattle P-I report on yet another counterproductive incentive: making it cheaper to pollute in bulk.

The more hazardous waste you produce in Washington, the better the deal you can get from the state. Companies that make chemicals, oil, paint, paper and airplanes must pay a Hazardous Waste Planning Fee for the toxic substances that they pump into the air and water or send to landfills. But because the fee is capped, the top five producers pay less than $8 a ton for their dangerous waste, whereas companies producing smaller amounts can pay up to $250 a ton.

ConAgra: No more toxic fake butter

Clearly not responding to my post from yesterday — but rather to steady pressure from the Project on Scientific Knowledge and Public Policy and other groups — ConAgra announced it would stop using diacetyl in its Orville Redenbacher and Act II microwave popcorn brands. Diacetyl, a fake butter flavoring, has been known for years to […]

While the FDA and EPA look away, noxious fumes from fake butter wreck lungs

Back in May, I drew attention to the remarkable fact that food-industry workers are literally dying from exposure to a key ingredient in microwave popcorn. The food additive diacetyl (responsible for that "buttery note" in nuked popcorn and also in margarine) emits a noxious fume when heated up — one that can literally destroy people’s […]

Environmental scientist Theo Colborn warns about the chemicals all around us

This guest essay comes from Theo Colborn, an environmental health analyst, professor of zoology at the University of Florida, Gainesville, and president of The Endocrine Disruption Exchange (TEDX). She's one of the experts featured in Leonardo DiCaprio's new eco-documentary The 11th Hour, which opens in L.A. and New York on Aug. 17 and in other spots around North America on Aug. 24.

What a crazy world we live in when almost everyone knows what the acronym ED stands for. Millions of dollars have been poured into creating awareness of ED, erectile dysfunction, because it is profitable. This 21st-century sales-pitch strategy -- "disease mongering" -- has proven to be good for the bottom line. The irony of all this is that there is another ED out there into which millions have also been poured -- to keep it a secret. That ED is endocrine disruption, and if the public were to learn about it, bottom lines could shrink instead of grow.

Endocrine disruption should be right at the top of the list of most critical technological disasters facing the world today, up with climate change. With little notice, vast volumes and combinations of synthetic chemicals have settled in every environment in the world, including the womb environment. Synthetic chemicals at very low concentrations in the womb change how genes are programmed, cells develop, tissues form, and organs function, and thus undermine the potential and survival of developing animals, including humans. The chemicals threatening the integrity of future generations are derived from the processing of crude oil and natural gas, the same processes that are driving climate change. This is an integral part of the climate change story.

Cats are the canaries of PBDEs

This is my cat, George. He is fat and grouchy, but I love him. He likes to sun himself on the patio.

This is a link to Sightline's research on PBDEs, toxic flame retardants. A couple of years ago, we conducted a study of PBDEs and found high concentrations in the breast milk of nursing mothers throughout the Pacific Northwest. It was bad news.

And what's the connection to George? Well, new scientific research shows that PBDEs are making house cats sick. (Major hat tip here to Lisa Stiffler, ace environmental reporter at the Seattle Post-Intelligencer, who covers the story in her blog today.)

From a summary of the study:

PBDE concentrations in blood serum of the 23 house cats participating in the study were 20-100 times higher than the median levels of PBDEs in people living in North America, who have been shown to have the world's highest human PBDE levels.

PBDEs are long-lived. They're found in foam cushions, TVs, computers, carpet pads, curtains, you name it. It's thought that we humans get our exposure to PBDEs through house dust, which often includes crumbled bits of foam and other goodies. Same goes for cats: researchers believe that felines, with their obsessive-compulsive grooming, are literally lapping up the toxic compound. And many cats (George included) eat a lot of fish, which tends to have high concentrations of toxics, too.

Toxic fun

Once again, it turns out plastic toys from China are more than just an eyesore -- they're a hazard. A toy recall of 86 Fisher Price products, including several branded toddler favorites like the Dora and Elmo, was issued yesterday because of a lead-paint hazard. After scrolling the list, I decided my kids were safe -- for now. At least I think so.

Enemies of the human race

Last week, I put up a post explaining that BP will be increasing their dumping of toxic waste into the Great Lakes.

Congress overwhelmingly approved a resolution condemning BP's dumping -- a resolution sponsored by Rahm Emanuel, a powerful Democratic Congressman.

Now, thanks to some fine investigative reporting by the Chicago Tribune, we find out that BP has been dumping mercury as well, and will continue to do so:

Federal records analyzed by the Tribune show BP puts 2 pounds of mercury into the lake every year from its sprawling plant 3 miles southeast of Chicago in Whiting, Ind. That amount is small compared with the mercury that falls into the water from air pollution, but mercury builds up in the environment and is so toxic that even tiny drops can threaten fish and people.

A little-noticed exemption in BP's controversial new state water permit gives the oil company until 2012 to meet strict federal limits on mercury discharges.
