摘要：
The distributions of organochlorinated pesticides (DDTs, hexachlorobenzene -HCB- and lindane) and polychlorinated biphenyls (PCBs) have been determined in mussels from two bays of the Ebro Delta (Western Mediterranean) during the period 1980-1992. The data obtained enabled us to assess the fate and trends of these compounds in the area. A general decline in concentrations was observed for all organochlorinated pesticides during the studied period, reflecting a positive response to the existing regulations. However, the decline of PCBs was less evident, although a relative decrease of the low chlorinated congeners with time, possibly indicating a lack of recent inputs, was observed.
