Fish Tissue Analysis for Mercury and PCBs from Commercial Fish/Seafood Markets

April 2011 - Vol. 30

Federal vs. State: Federal

Description: In response to a recent Health and Nutritional Examination Survey conducted by the NYC Dept of Health and Mental Hygiene that identified elevated blood mercury concentrations in adult NYC residents, EPA has conducted a study to determine the mean mercury concentration of fish/shellfish species commonly consumed by New Yorkers. The intent of this study is to provide information that gives meaning to the phrase "Eat Fish, Choose Wisely" (NYCDOHMH). Twenty two commonly consumed species were sampled. The number of samples analyzed ranged from 4 - 16. Generally, a sample was a composite of three individual specimens, although for some small species (e.g. clams, shrimp, mussels) numerous specimens constituted an individual sample. All samples were obtained from the Fulton Fish Market (Bronx, NY) in May/June, 2008. The study is a collaborative effort between ORD and Region 2. In addition to mercury analysis, a subset of the samples were analyzed for PCBs. NCEA is the ORD lead office for the study and is providing project management and statistical consultation. NRMRL provided contract services out of their lab in Edison, NJ, for sample collection and preparation. NERL's Cincinnati lab performed DNA sequencing for the fish samples to positively identify species. The Region 2 lab in Edison performed the mercury and PCB tissue analyses. The report is currently undergoing internal peer review and will be submitted for external peer review.
