Abstract: A QSAR (Quantitative Structure -Activity Relationship) model was put forward to quantitatively predict bioaccumulation of organic compounds in fish on the basis of a dataset of 214 diversified compounds in which 54 compounds served as test set and the rest as training set. About 193 molecular indices were calculated for each compound. From the analysis of the models, the predictability of stepwise MLR was satisfactory (R^2 = 0. 81, R^2 = 0.66) for the present work. In addition, the relationship between log BCF and lg P was also reasonable (R^2 = 0.62) , indicating that all these studies was helpful for prediction of bioaccumulation of organic compounds in fish.
