¹⁴C-DDT dynamics in a cold water model food chain
The uptake, elimination, and metabolism of ¹⁴C-DDT in a maple leaf-scud-rainbow trout food chain was investigated using gas chromato graphy, liquid scintillation, and thin-layer chromatography-autoradiography. In this modular food chain, both scud and rainbow trout accumulated more DDT from the water than from food. After adjusting for growth in the trout, scud and trout showed little elimination of residue after exposure ceased. DDT was metabolized to DDE by both organisms. The results of this study will be a baseline for comparison of the dynamics of other compounds in this model.
