EPA’s Destructive Workfare Economics: Pointless GE PCB clean-up creates 350 jobs at a cost of $2.86 million per job

That doesn’t include jobs created for lawyers and lobbyists, including at the utility GE is now suing — all over a clean-up that is not only unnecessary, but actually causing water pollution. Continue reading

GE to stir up even more Hudson River PCB sediments

No doubt a never-ending process — as news PCBs are stirred-up and settle, they’ll “need” to be dredged. Continue reading

PCBs, other pollutants delay pregnancy?

Given much higher exposures during the mid-20th century, would there have been baby-boomers or Gen-Xers if this were true? [NIH News]

I’m so relieved: PCBs levels down in Norwegian polar bears

It’s never been easy to be a polar bear. They may have to go months without eating. Their preferred food, seal, requires enormous luck and patience to catch. Add to that the melting of Arctic sea ice due to climate change, and the poisoning of the Arctic by toxic chemicals, and it’s easy to see why polar bears worldwide are in trouble (sic).

Should military training be constrained by “pollution fears”?

Navy ‘Sinkex’ raises pollution fear – In 2005, the USS America aircraft carrier was towed out to sea on her final voyage. Hundreds of miles off the Atlantic coast, U.S. Navy personnel then blasted the 40-year-old warship with missiles and bombs until it sank. Continue reading

Made in China: POPs linked to birth defects?

A new study in the Proceedings of the National Academy of Sciences claims to link placental levels of various “persistent organic pollutants” (POPs) with neural tube defects (NTDs) in a population of rural Chinese. Continue reading

The EPA’s dim bulbs

“After weathering a winter of intimidation, Mayor Bloomberg has apparently capitulated to an Environmental Protection Agency scare campaign. The issue: PCBs — three little letters that are about to sock New York schools with another $700 million funding drain.” (New York Post)

EPA, not PCBs, the problem in NYC schools

About the PCBs-in-schools scare, the NY Daily News opined:

Overzealous enforcers at the U.S. Environmental Protection Agency’s New York regional office have whipped parents into a frenzy and are threatening to force the city into spending untold millions on a crash cleanup. They need to back off… Only recently did the EPA come up with what the agency considers an acceptable level of PCBs in the air of a classroom. It defines an “elevated level” of the chemical as anything more than 300 nanograms per cubic meter of air – an extremely conservative guideline that leaves a huge margin of error. By the agency’s own math, it’s 300 times less than the amount that would give a child a 1-in-10,000 chance of suffering harm even after long-term exposure.

Even the media can debunk a needless $700 million clean-up in cash-strapped times.

PCB-IVF study fails implantation

Just published online in Environmental Health Perspectives is a study attempting to link failed in vitro fertilization with PCBs. But the researchers ignored the classic multiple comparisons problem. Here, 57 congeners were tested and only one produced significantly elevated dose-dependent odds of failed implantation — less than you’d expect by chance at a 5% error level. Moreover, the association between all PCB congeners and failed implantation wasn’t significant. Finally, the researchers considered no other confounding risk factors for the failed implantation. No wonder this was published in EHP.

Bloomberg: PCBs in schools not so dangerous

Faced with a $700 million remediation effort, Mayor Bloomberg says school kids are exposed to more PCBs from a tuna fish sandwich than the light fixtures in city schools. But when cash-strapped New Yorkers turned to local waterways for food in 2009, the Mayor said “common sense” dictated that anglers shouldn’t eat fish from PCB-contaminated water.
