| Abstract: | The total concentrations (tDDT) of DDT 1,1,1-trichloro-2,2-bis(pchlorophenyl)ethane], DDD 1,1-dichloro-2,2-bis(p-chlorophenyl)ethanel, and DDE 1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene] in Emerita analoga from 19 California beaches reflect tDDT contamination nearby. Animals near the Los Angeles County sewer outfall contain over 45 times as much tDDT as animals near major agricultural drainage areas. Sediments near the outfall probably contain over 100 metric tons of tDDT-a reservoir for input into marine organisms. The effluent from a plant that manufactures DDT is a probable source. |
