Analysis reveals water quality is polluted in the Polezhayevka River catchment, indicating biotic interactions influence primary production.

To analyze the relationship between abiotic and biotic components in the Polezhayevka River catchment.
Assessment of water quality indicators to determine pollution levels
Analysis of biogeochemical characteristics of bottom sediments and soils
Measurement of organic carbon content and hydrocarbons
Examination of phytopigments and primary production contributions
Water quality was assessed as polluted based on multiple indicators
Organic carbon content was 5.9% in bottom sediments and 6.8% in soil
Hydrocarbon levels exceeded background in bottom sediments (1.6 times) and soil (1.2-1.7 times)
Primary production contributed 1.53% of total carbon in bottom sediments and 0.61% in soil
