ЗАГРЯЗНЕНИЕ ДОННЫХ ОТЛОЖЕНИЙ ОЗ. БАЙКАЛ ПОЛИЦИКЛИЧЕСКИМИ АРОМАТИЧЕСКИМИ УГЛЕВОДОРОДАМИ

The paper presents the results of completed in 1981–1988 surveys of benzo (a) pyrene and other polycyclic aromatic hydrocarbons concentrations in the lake Baikal. We studied the distribution of the pollutants in the surface layer of bottom sediments of the lake in the area of sewage of the Baikal Pulp and Paper Mill and in the sewage plant and the lake water. It was found that the content of benzo (a) pyrene in the bottom of the test site in the sewage plant and the lake water is often signifi cantly higher than the requires quality of the environment and the natural background of the lake. Previously, these data could not be published because of existing restrictions.
