The toxicity of Lake Onego sediments in connection with the natural and anthropogenic factors influence

N.M. Kalinkina, A.I. Sidorova, N.A. Galibina, K.M. Nikerova


The toxicity of the sediments detected in the northern bays of Lake Onego is determined by anthropogenic factors (pulp-and-paper industry and communal waste waters). Besides the toxic bottom sediments were observed in the central deep part of Lake Onego, which is connected to the geotectonic features of the area.
