Abstract:
Bioconcentration and toxicity of 22 substituted nitrobenzene and aniline compounds to aquatic organisms were assessed with quantitative structure-activity relationship (QSAR). Acute toxicities of aquatic organisms, including daphnia (Daphnia pulex) and carp (Cyprinus carpio), to 22 chemicals have been determined in our previous work. In this study, the bioconcentration factors (BCFs) for carp were further investigated. By the use of multiple-regression analyses, the molecular connectivity indices (MCIs) can describe both acute toxicity and bioconcentration for the test organisms. Applicable QSAR model (0.856
