Migration of mercury in the food chains of the Beloosipovo biocenosis (part 1)

Introduction. Mercury and its compounds are among the most dangerous toxic substances, which makes mercury pollution one of the most urgent environmental issues. The present research objective was to study the accumulation of mercury and its impact on the terrestrial ecosystems in the area of the Be...

Mercury and its compounds are among the most dangerous toxic substances, which makes mercury pollution one of the most urgent environmental issues. The present research objective was to study the accumulation of mercury and its impact on the terrestrial ecosystems in the area of the Beloosipovo mercury deposit (Kemerovo Region, West Siberia, Russia). Study objects and methods. The study used standard methods to test soil, herbs, herpetobiont insects, and small mammals. The sampling was conducted at 13 points in the cardinal directions at 0.5, 1.5, and 3 km from the pollution source. The method of atomic absorption was employed to measure the concentration of mercury in the samples prepared by the wet mineralization method. Results and discussion. The main components of terrestrial ecosystems revealed no excessive concentration of mercury in the soil. However, the water samples from the Belaya Osipova river demonstrated an excess in the maximum permissible concentration of mercury from 5 to 20% (0.00056–0.00074 mg/L). Further up the food chains, the concentration of mercury in organisms decreased by 1–2 orders of magnitude, depending on the sampling point. The study also revealed Siberian trout lily (Erythronium sibiricum (Fisch. et C. A. Mey) Kryl.), which is protected at the federal and regional levels, as well as several nemoral tertiary relics. Conclusion. The decreasing concentration of mercury in the food chains means the ecosystem is under no severe negative impact.Alexander Yu.
