【 摘 要 】

The article considers the research of the plant pigments content in the upper layer of the bottom sediments in the rivers (the Serovka, the Yagorba, the Sheksna), which are affected by communal and industrial wastewater in Cherepovets. The average content of pigments in the bottom sediments of the Serovka and the Yagorba rivers was higher than in the Sheksna river during the observation period (July 2015 - December 2016). According to the indices E480 / E665, E480 / (1.7E665k) and the ratio of chlorophyll to pheophytin, the pigmentary fund of benthic algocenoses is mainly in a degraded state. In terms of chlorophyll and pheopigments (calculated on dry soil) amount, the bottom sediments of the Serovka river are characterized by the mesotrophic category values, while the ones of the Yagorba and the Sheksna rivers - by oligotrophic values.
