Abstract
The concentrations of chlorinated phenols (CP) have been determined in superficial water of Selenga River and its basic tributaries, which provide for 53 % of the Baikal Lake drainage. It has been found that a level of contamination of the Selenga River basin by CP is relatively low and the total CP content comprises 0.36-1.85 mg/l. The presence of CP in natural water is caused mostly by the local anthropogenic and natural sources, for identification of which the use of the ratios of net concentrations of 2,4,5- and 2,4,6-trichlorophenols and 2,4- and 2,6-dichlorophenols, together with 2,4,5- and 2,4,6-trichlorophenols and 2-chlorophenol is suggested.
