Compared with other PCB congeners, these compounds can be considerably bioconcentrated, and retained, by bivalves and constitute a potential health hazard for higher consumers. To evaluate the health risks that these PCB congeners pose for human beings, concentrations in oyster samples from two of the largest bays on the northern Gulf of Mexico coast, Galveston and Tampa Bays, sampled as part of the NOAA's National Status and Trends 'Mussel Watch' Programme, are discussedASW,USA,Florida,Tampa BayASW,USA,Texas,Galveston BayBaysbioaccumulationBivalvescarbon chromatographic methodCrassostreaCrassostrea virginicaenvironmental conditionsFood contaminationHuman foodO 4020 POLLUTION - ORGANISMSP 1000 MARINE POLLUTIONPCBPCB compoundsplanar PCB congenersPublic healthQ1 01627 Food quality and standardsQ5 01504 Effects on organismsRiskRisksShellfishTexasUptakeUSAUSA,FloridaUSA,TexasX 24120 Food,additives & contaminantsX 24156 Environmental impactX 24163 MetabolismJournal
