We estimated the toxic effect of benzene, phenol, and catechol on the logarithmic phase of growth of Chlorella vulgaris, Beijerinck 1890 cultures; the compounds show various degrees of toxicity to the algae. A concept was developed concerning each compound's toxicity index EC50/(T2-T1) The concept assumes the calculation of the index as well as benzene, phenol, and catechof-ináuced inhibition of test cultures growth f(T2-T1,) in T2-T1, interval which corresponds in our experiment to the logarithmic phase of control culture growth. f(T2-T1,) was proved to remain in linear relation to the initial concentration of the investigated substances in culture medium. Also, it was found that the values of EC50/(T2-T1), calculated by probit methods, are characterized by confidence intervals comparable to those determined for EC50/96 and EC50/Tmax (the indexes were determined at hour 96 and Tmax, respectively)
