Description:In 2017, the National Oceanic and Atmospheric Administration (NOAA) Mussel Watch Program (MWP) conducted an assessment of the presence, distribution, and concentrations of contaminants of emerging concern (CECs) in Eastern Oysters (Crassostrea virginica) from the Gulf of Mexico's coastal waters. The MWP utilizes a sentinel-based monitoring approach by collecting and analyzing bivalves as surrogates for coastal water pollution. Mussels and oysters are sessile organisms that filter and accumulate particles from water; therefore, measuring contaminant levels in their tissue is a good indicator of local chemical contamination. The oyster samples collected as part of the 2017 assessment were analyzed for alkylphenol compounds (APs), alternative flame retardants (AFRs), polybrominated flame retardants (BFRs) such as polybrominated biphenyls (PBBs) and polybrominated diphenyl ethers (PBDEs), current-use pesticides (CUPs), per- and polyfluoroalkyl substances (PFAS), and pharmaceutical and personal care products (PPCPs). Oyster tissue samples from 44 monitoring sites across the Gulf Coasts of Florida, Alabama, Mississippi, Louisiana, and Texas were analyzed in this study for a total of 13 - 244 individual CEC compounds, depending on the site location.
