| Abstract: | The article presents the results of hydrochemical studies of two areas, open and closed, in the littoral zone of Lake Onega, carried out in 2013–2014. The results show that water of river and slope runoff, enriched with both biogenic elements and allochthonous organic matter, persist over a long time in spring in the littoral zone. In the summer, water chemistry at open shores is similar to that in lake pelagic zone, while the closed areas of littoral zone show the effect of biological processes. In the period of autumn homothermy, river and slope waters have no considerable effect on coastal water quality. |
