fate of 14C-DDT in the aquatic ecosystem utilizing nuclear techniques

Experiments were conducted to determine to uptake, distribution, bioaccumulation and elimination of 14[C]-DDT in aquatic model ecosystems under the influence of different pH values in dark and light at 26 +/- 1°C. Bioaccumulation ratios were high in the fish than algae and snails in dark and light at different pH values. From elimination data, it was found that, light was important for fish-residue loss, while snails need dark for residue loss except experiment at pH 8.2. Also some of residue loss were evolved as 14[CO][2] in elimination experiment
