Abstract:
QSAR estimates of toxicity of relatively unreactive organic chemicals for 19 species of bacteria, algae, fungi, protozoans, coelenterates, rotifers, molluscs, crustaceans, insects, fish and amphibians were used to predict 'no-effect-levels' (NELs) at the ecosystem level by means of a recently developed extrapolation model. Equilibrium-partitioning theory for sediment and water was used to derive NELs for aquatic sediments. A simple table is given from which NELs for water and sediments can be predicted on the basis of only the octanol-water partition coefficient and molecular weight.
