You’ve probably heard that a F/A-18D jet crashed in San Diego on approach to Miramar, killing 3 on the ground (the pilot ejected and is fine). A lot of the news reports noted that ~20 homes were evacuated due to ‘toxic chemicals’. What sort of chemicals would you be worried about? First Responders and Bystanders…

Well, if MacGuire was talking about getting into toxicology research on plastics, he was right on. EHP has published a study showing that the additive BPA can cause cells to suppress adiponectin. That would cause insensitivity to insulin and may be behind “metabolic syndrome“. Let’s pause for a moment and think about that name. That’s…

Read some background on PFOA and Teflon here. A couple of years ago DuPont and other perfluorochemical industries were dismissing evidence of PFOA-caused cancer in rats, saying it was due to peroxisome proliferation in rats, which some argue isn’t relevant to humans. However, PFOA may have other mechanisms of action (disrupting thyroid hormones, gap junctions,…

Oops! In case you didn’t know, the Boulder, CO site of the National Institute of Sandards and Technology (NIST) had an accidental spill of plutonium-239 on June 9 and the initial actions taken would have an industrial hygenist pulling her hair out (read more at C&EN). Basically, a guest researcher* cracked a bottle, didn’t realize…

Do you ever wonder how some people can simply dismiss the risks of toxic products that they keep around them? This is a constant source of wonderment in the public health community. The reflexive answer is usually that people in question are just uninformed. Therefore we put lots of effort into education. This doesn’t jibe…

A paper just published in Tox Sci shows that PFOS (the chemical that used to be the prime ingredient in Scotchgard) suppresses the immune system at levels, that didn’t cause noticeable toxicity that are same as what are found in the general population. Great. So, basically, many people in the US who show no other…

Good reading for today: Ken Sepkowitz on why we should eat more excrement. Truly, he makes an excellent point. One other thing that he doesn’t mention is that as we get safer the outbreaks that exist look worse and worse. Has anyone done a study of whether eating charred foods protects against cancer? (possibly better…

Perhaps I should call this entry Mr Kawamura, CA secretary of the state department of Food and Agriculture, is a moron. Background The Monterey area has a problem with the light brown apple moth. Apparently it’s been there for a while but now the state is concerned. They want to spray a pheramone to disrupt…

Chemical Trespass Redux

So I if walked over to your house and dumped something over your fence, that’s probably trespassing, unless that something happened to be a box of Krispy Kreme, then it’s just tasty. If it’s grass clippings, you’d be pissed off; if it’s an industrial chemical, you might sue. If I came over with said chemical…

Antibiotic Salad Anyone?

Scientists took lettuce, corn, and potatoes and grew them using soil treated with hog manure that had the commonly used livestock antibiotic Sulfamethazine in it. All three plants uptook the Sulfamethazine. You know what that means: mmmmm… Wait, no, I think I meant yuk. With 9-13 million kg of livestock antibiotic used every year and…
