Analysis of accumulation of heavy metals from river bottom sediments of the urban environment in the bodies of oligochaetes

Resumo

The content of heavy metals in the bodies of oligochaetes in two small rivers that flow along the central part of a large industrial city has been studied. It has been established that the concentration of mobile (bioavailable) forms of metals in oligochaetes is higher than that in bottom sediments. The similarity of the pattern of accumulation of pollutants in the bodies of oligochaetes and the correlation of heavy metals with the organic matter of river sediments has been revealed in both urban watercourses.
