Twelve surface soils from paddy field and fourteen sediment samples from lake and river at different locations of Dhaka city were collected during remonsoon ransition and rainy seasons. ichlorodiphenyl richloroethane {DDT) was measured using ELISA Enzymed-Linked Immuno Sorbent Assay) method. All soil (0.001-0.038 ppm) and sediment samples (0.0013-0.040 ppm) except two lake sediments contained DDT. The sail and sediment matrices oy different locations were contaminated by DDT where it was used for public health purposes. Cfay and organic colloids seemed to be the carrier in transporting DDT from primary to secondary saurces. Correlations were made between DDT
and physicochemical properties of soil and sediment samples where positive relatianship of DDT existed only with organic matter and clay content of both soil and sediments.
