摘要：
The results of studies of water chemistry carried out in the water body in 1965-2009 are presented. This period features a considerable industrial and agricultural rise in the lake drainage basin, followed by a decline since the 1990s, manifesting themselves in the dynamics of some hydrochemical characteristics of water bodies. The multipurpose use of Onega Lake is shown to cause its pollution and eutrophication. The results of studies are used to evaluate the major components of the external load onto the lake and trends in variations of chemical characteristics under the effect of natural and anthropogenic factors.
