Chemicals

"The discovery of persistent, bioaccumulative, and toxic flame-retardant chemicals everywhere from animals north of the Arctic Circle to the breast milk of California women has been a cause for considerable concern. Alternative flame retardants were introduced to replace these chemicals, but investigators had not even produced the first empirical data on the substitutes’ metabolic fate and toxicity before emerging evidence indicated they, like their predecessors, were accumulating rapidly in the environment. As the postmarket research continues, one wonders: Who, exactly, decides on the replacements for toxic chemicals, and on the basis of what criteria? And why does finding truly safer alternatives seem so difficult?"

"The news just keeps getting worse for bisphenol A. Lab and animal research has linked it to reproductive disorders, obesity, diabetes, and cancers sensitive to hormonal activity, like those of the breast and prostate. Studies show that more than the vast majority of Americans have measurable levels of BPA in their urine (though as Sydney Brownstone wrote on this blog yesterday, Old Order Mennonites seem to have less)—not surprising given that the chemical is used in thousands of consumer products, including cans and plastic packaging for food and beverages. Now a new study from China has found an association, for the first time, between human exposure to BPA and brain tumors."

"NASHVILLE, Tenn. -- Laboring in the blackberry fields of central Arkansas, the 18-year-old Mexican immigrant suddenly turned ill. Her nose began to bleed, her skin developed a rash, and she vomited."

"CHEYENNE, Wyo. -- Forest Service officials insist firefighting won't be hindered by new rules meant to prevent millions of gallons of retardant dropped onto scorched landscapes each year from poisoning streams and killing fish and plants."

"A bioactive chemical cousin of BPA turns up on money and in receipts"

"U.S. Democrats in the House of Representatives urged the Obama administration on Wednesday to expand proposed regulations for fracking for natural gas, saying companies should be required to reveal the chemicals to be used in the process prior to drilling."

"Gov. Jerry Brown urged state regulators Monday to reduce the prevalence of chemical flame retardants in household furniture, joining a growing number of critics who argue the chemicals are toxic and unnecessary."

Spraying for mosquitoes has begun in Florida, as in many other places. Some of the sprays can be harmful to the environment. Is the cure worse than the problem?
