Since 1986, the National Oceanic and Atmospheric Administration's (NOAA) National Status and Trends (NS&T) Program has included a component called the Mussel Watch Project that has annually collected and chemically analyzed mussels and oysters from 177 sites around the coastal and estuarine United States. At 132 of those sites mollusks have been collected in all three years. The chemical contaminants analyzed have included polyaromatic hydrocarbons, polychlorinated biphenyls, chlorinated pesticides, and 12 trace elements. The main reason for analyzing mollusks is to establish temporal trends.
