Title: β -cyclodextrin(β -CD) influence on the biotoxicities of substituted benzene compounds and pesticide intermediates
Abstract: The acute toxicities of 19 substituted benzene compounds and intermediates of pesticides to Photobacterium phosphoreum in beta-CD aqueous solution (5 g/L) were studied and compared with those in water through luminescent bacteria toxicity test, and 15min-EC50 values were obtained. The presence of beta-CD significantly reduce biotoxicities of the low-polarity compounds, while for the higher-polarity compounds, such effect was slight. The differences of biotoxicities were correlated with Log10Kow (octanol/water partition coefficients). A significant linear relationship was obtained with some abnormal data picked out. Some explanations concerning molecular structure of chemicals as well as beta-CD were given for the relationship.
