Norm Index–Based QSAR Model for Acute Toxicity of Pesticides Toward Rainbow Trout

The aquatic ecological environment is being threatened from overuse of pesticides, and the aquatic toxicity toward rainbow trout ( Oncorhynchus mykiss ) plays a significant role in environmental risk assessment of agrochemicals. In the present study, 2 norm index formulas were developed, from which several norm descriptors were derived. A quantitative structure–activity relationship (QSAR) model was established for the prediction of acute...
