Chemical Contaminants in Oysters and Mussels

NOAA's State of the Coast Report.

- N/A

Since 1986, the Mussel Watch Project of the National Oceanic and Atmospheric Administration (NOAA) has chemically analyzed mussels and oysters collected annually from coastal sites throughout the Nation. Results show that concentrations of most of the monitored man-made chemicals (e.g., DDT, PCBs) are decreasing. The concentration of cadmium is decreasing as well, but concentrations of other trace metals have stayed more or less constant. Many chemicals, particularly those that are man-made, have high concentration levels near cities. Except in the case of lead, however, there is no apparent association between high concentrations of other trace elements (e.g., mercury, copper, zine) and urban areas
