experiment was 41.9 yg/g wet weight, at the end 29.3 yg/g. This loss of 

 only about 30% in 120 days was interpreted as demonstrating that hard clams 

 are only slowly depurated of petroleum hydrocarbons. Persistence of con- 

 tamination is related to duration of exposure and chemical composition of 

 source hydrocarbons. - J.L.M.

At the second trophic level, crustaceans and molluscan shellfishes, including 

 Mercenaria (Venus) mercenaria, were studied. All accumulated strontium 

 rapidly from seawater. Soft parts of hard clam, at the end of 20 days, had 

 accumulated cesium!37 j-,y a f ac tor of six over the concentration in surrounding 

 seawater and the concentration had not yet reached a steady state. - J.L.M.

Sixty five percent show some reduction of coliform density, 35% show no 

 reduction or an increase. Fifty percent of the samples show at least a 30% 

 reduction. Twenty-five percent of samples show at least 64% reduction. 

 Species treated was My a arenaria. Other depuration plants were treating 

 Mercenaria mercenaria for a short time with limited success. - J.L.M.
