Abstract
The concentrations of zinc (Zn), cadmium (Cd), lead (Pb) and copper (Cu) compounds in bottom sediments and surface waters of the Chernaya River in St. Petersburg in the spring-summer and autumn periods were determined. Analysis of water quality at the river source (sampling point S1) revealed a persistent anthropogenic impact on the water system associated with heavy metal pollution throughout the entire observation period. The ecological situation in bottom sediments was assessed. The most polluted areas were found near the source of the river, at point S1. According to the geo-accumulation index (Igeo), contamination with cadmium and copper is assessed as moderate, while for mercury (Hg) this indicator ranges from moderate (spring) to severe (summer). In areas with high anthropogenic impact, the proportion of mobile forms of metals in bottom sediments increases.
期刊介绍：
Russian Journal of General Chemistry is a journal that covers many problems that are of general interest to the whole community of chemists. The journal is the successor to Russia’s first chemical journal, Zhurnal Russkogo Khimicheskogo Obshchestva (Journal of the Russian Chemical Society ) founded in 1869 to cover all aspects of chemistry. Now the journal is focused on the interdisciplinary areas of chemistry (organometallics, organometalloids, organoinorganic complexes, mechanochemistry, nanochemistry, etc.), new achievements and long-term results in the field. The journal publishes reviews, current scientific papers, letters to the editor, and discussion papers.
