Abstract
In the course of monthly sampling during the years 2008-2010, two regions of the littoral of the Enisey river were compared, one of them (conventionally pure) was situated upstream of Krasnoyarsk and the other (conventionally polluted) downstream of Krasnoyarsk. The concentrations of heavy metals, oil products, phenols, biogenic elements and essential polyunsaturated fatty acids (PUFA) in various components of the river ecosystem were determined. It was discovered that the anthropogenic pollution causes a decrease in the resources of essential PUFA in the biomass of the upper links of the food chain of the river ecosystem.
