Studies of deposition of dieldrin concentrations sublethal to fish were conducted in flowing and non‐flowing aquatic systems. Residual concentrations were determined for water, soil, plants, and fish in 18 flowing and 18 static artificial systems, after treatments of 24, 36, 48, and 72 h, in a farm pond. Samples from each of the four components were analyzed for dieldrin residues by gas chromatography. Two aquaria with aerated water but without biological components were tested. The distribution of dieldrin was similar in the waters of the closed, flowing, and farm‐pond systems. Soils contained little dieldrin but the compound was accumulated rapidly and as high as 474 ppb (parts per billion) and 3,950 ppb by plants and fish, respectively. The concentration of the insecticide declined with time in the three systems (soils, plants, and fish).
