Abstract 2,4,6-Trichlorophenol, pentachlorophenol,p-chlorobiphenyl, and hexachlorobenzene were sprayed over an outdoor experimental pond and their time-dependent changes in concentration in sediment, fish, and water samples were determined for a period of 60 days. A model was assumed which described the movement and distribution of the compounds in the system. The rate constants for volatilization of these compounds from water, accumulation and excretion by fish, sediment sorption and desorption, and photolysis were also determined in laboratory experiments. The concentrations of these compounds were estimated, based on the hypothesis that the compound transfer could be expressed as a first-order rate process. It was demonstrated that the concentration changes of these compounds in the outdoor experimental pond could be estimated roughly from the model and the rate constants which had been determined in laboratory experiments.
