Abstract
Abstract: The absorption, accumulation and elimination of PCB (Clophen A50) in goldfish was studied. To ensure well‐defined and reproducible PCB concentrations in the water phase (0.01, 0.05, 0.10 and 0.50 p.p.m.) the experiments were made in aluminium foil containers. A rapid uptake and accumulation was observed but only slight changes in the relative composition of the absorbed PCB's were found. In the elimination experiment it was found that the content of PCB in the fish was halved during the first three weeks of the experimental period but that the half‐life for PCB rose during the experiment.
