Young, David R., Robert J. Ozretich, F. A. Roberts, O.A. Brinken, and I.N. Taganov. 1999. Evaluation of polynuclear aromatic hydrocarbon (PAH) contamination of Lake Baikal and Angara River surface waters. Journal of the Russian Academy of Science, Russian Geographical Society 131(1)65-69.

This paper reports concentrations of polynuclear aromatic hydrocarbons (PAH) determined in small samples (l,5 L) of near-surface water in a 1993 survey of the relatively non-contaminated surface waters of southwestern Lake Baikal and its Angora river measured by gas chromatography-mass spectrometry. Blank-corrected concentrations along the northern shore of the lake near Listvyanka ranged from 0.01 ng/L (3,6-dimethylphenanthrene, benzo(e) pyrene) to 5 ng/L (napthalene). Concentrations in the Angora River outflow above and within the city of Irkutsk were approximately three-fold higher. Average PAH concentrations in the lake water were only about 1 percent of those measured just inside the San Diego Harbor in Southern California, U.S.A., and were many orders of magnitude below reported levels of acute toxicity.
