Relationship between water solubility of chlorobenzenes and their effects on a freshwater green alga
The effective concentrations of benzene and 12 chlorobenzenes that reduced 50% of the primary productivity (EC50) of a freshwater green alga, , were determined. Benzene was the least toxic chemical and the toxicity increased as the degree of chlorine substitution in the aromatic ring increased. No EC50 value could be obtained for HCB. A quantitative relationship was found to exist between water solubility, lipophilicity and the EC50. A good correlation was also observed between the EC50 for this alga and other toxicity data for various aquatic biota. 相似文献
