Résumé / Abstract

Two independent training sets were used to develop four mathematical models for predicting aerobic biodegradability from chemical structure. All four of the models are based on multiple regressions against counts of 36 preselected chemical substructures plus molecular weight. Two of the models, based on linear and nonlinear regressions, calculate the probability of rapid biodegradation and can be used to classify chemicals as rapidly or not rapidly biodegradable. The training set for these models consisted of qualitative summary evaluations of all available experimental data on biodegradability for 295 chemicals. The other two models allow semi-quantitative prediction of primary and ultimate biodegradation rates using multiple linear regression
