Aliphatic hydrocarbons in Gulf seafood test at DOUBLE the risk level set by U.S.-funded working group — “Associated with liver damage”


Panel challenges Gulf seafood safety all-clear, MSNBC, December 27, 2010:

[William Sawyer, a Florida-based toxicologist] says [tests] are routinely turning up long-chain “aliphatic” hydrocarbons associated with liver damage. ...

[S]cientists from industry, government and academia who banded together in the 1990s to develop guidelines for public health officials and environmental engineers faced with petroleum-related exposure and contamination. The work of the U.S.-funded Total Petroleum Hydrocarbon Criteria Working Group was part of a flurry of research that occurred in the wake of the Exxon Valdez spill in Alaska. ...

Based on available animal and human research the scientists set risk levels for exposure to various groups of hydrocarbons.

That is the standard that Smith's scientists are relying on to argue that levels of aliphatic hydrocarbons in the seafood samples are about twice as high as the risk level set by the hydrocarbon group.

Sawyer, the toxicologist, said that daily exposure above the risk level poses a risk of liver damage, especially for people who have underlying health issues...
