Abstract

Composition of bottom sediments of the Lake Muchke (basin of the Tatar Strait). L.A. GARETOVA,
N.K. FISHER (Institute of Water and Ecological Problems, FEB RAS, Khabarovsk).

Granulometric composition, Corg, aliphatic and volatile aromatic hydrocarbons (HC), phytopigments, and
bacteriobenthos of bottom sediments (BS) of the Lake Muchke (estuary of the small River Muchke of the Tatar Strait basin) were studied. Distribution of Corg, HC, phytopigments, bacteriobenthos in the sediments is caused by granulometric composition of BS. It was determined that the investigated components tend towards silty fraction. At a close content of Corg (2.6–3.7 %) and HC (1.25–1.42 mg/g) in the same type sediments (aleuritic-psammitic), the fraction of hydrocarbons in the Corg composition varied from 3.38 to 16.25 %. High concentrations of volatile aromatic HC (up to 141 mg/kg) in the sediments of the lake indicates that the bottom sediments contribute to secondary pollution of the water area.
