Although the US EPA released two studies claiming that "Little cancer risk from BP oil burn dioxin, new studies conclude" A sort of rebuttal article written by Mark Schleifstein of the Times-Picayune asks a lot of questions about how safe the EPA testing was. I agree with Mr. Schleifstein's conclusions. However, there are more concerns.
EPA claims that they tested for two families of toxic chemicals. These are the polychlorinated dibenzodioxins and polychlorinated dibenzofurans. But, how many chlorinated dioxins and furans did they test ? The International Agency for Research on Cancer (IARC) has declared that three dioxin like poisons are now "human carcinogens". These are 2,3,7,8 tetrachlorodibenzo-dioxin, 2,3,4,7,8-pentachlorodibenzo-furan, and 3,3,4,4,5 pentachlorobiphenol. The EPA did not break down whether these three poisons were tested from the inadequate oil burn.
Imagine what could happen if these poisons got mixed together? And this doesn't include the other poisons. There are 75 chlorinated dioxins, 134 chlorinated difurans, and 209 polychlorinated biphenols. Please keep in mind that this does not include the brominated dioxins and furans, the polybrominated diphenol ethers, the chlorinated napthalenes, What do a lot of these poisons have in common: Perhaps a lot of them look "dioxin like"! Could they provide a much larger poisoning if combined?
What is EPA doing? Are they trying to stop mass hysteria? Perhaps preventing a social uproar is not practical. BUT, what about testing for alot of factors for acute toxicity. Also an epidemiological study which will encompass many years like the ones on Seves, Italy. However, then who would pick up the tab? I'm quite sure that BP would have nightmares over that suggestion. Maybe we should scrap the idea; after all, the dioxin explosions in Italy (76), England (60's), Germany, France,Austria, Holland, Russia. All of these countries had studies which showed injury from exposure to dioxin like chemicals. And let us not forget the Dow Chemical Company. Oh, that's right, Dow's studies didn't show anything but a skin rash.
