The acute toxicity of 13 quaternary ammonium compounds (QACs) to Chlorella pyrenoidosa and Scenedesmus quadricauda was investigated in the present study. Significant inhibition on algae biomass was observed and 96 h EC(50)-value of 13 QACs was tested. Sixteen physicochemical and quantum chemical parameters of the QACs were calculated using the semi-empirical MOPAC AMI method. The multiple linear regression (MLR) was employed to derive the quantitative structure-activity relationship (QSAR… CONTINUE READING
