摘要：

Long term DDT contamination is reported of a small lake which previously was recipient of the insecticide wastes from a plant nursery. 19 years after closing down of the outfall sum-DDT in perch and pike exceeds an assumed ''high background level'' by about 5-10 times. Gradient studies of sediments and perch indicated that deposits in the close vicinity of the former outfall still acted as a source for contamination of the more distant parts of the lake. Comparison with 1975 data nevertheless showed that DDT levels in fish had been reduced by about 90% and a rough estimate indicated a ''half life'' of DDT of 5-7 years.
