(TUSCALOOSA, Ala.) -- A bit more than a year after the worst oil spill in U.S. history occurred in the Gulf of Mexico, a University of Alabama review of multiple studies affirms that Gulf seafood contamination with polycyclic aromatic hydrocarbons, or PAHs, is "well below levels that would be of concern for human health."
However, given that PAH levels can remain elevated in fish and shellfish for weeks to years after contamination, the authors recommend continued testing. Additionally, they point out that testing for metals such as mercury, cadmium and lead should also continue, particularly since some are known to accumulate in seafood.
The report is published in Environmental Health Perspectives.
