Description
Summary:The characteristic properties of uptake and distribution of mercury in terrestrial ecosystems have received much lesser attention compared to aquatic particularly in Russia. Terrestrial ecosystems adjacent to large industrial manufactures—potential sources of mercury inflow into the environment frequently remain unstudied. This is the first report on mercury (Hg) levels in the basic elements of terrestrial ecosystems situated close to a large metallurgical complex. Mean values of mercury concentration (mg Hg/kg dry weight) in the vicinity of city of Cherepovets were the following: 0.056 ± 0.033—in the humus layer of soil; 0.556 ± 0.159—in earthworms; in the organs of voles Myodes glareolus (kidneys—0.021 ± 0.001; liver—0.014 ± 0.003; muscle—0.014 ± 0.001; brain—0.008 ± 0.002); in the organs of shrew Sorex araneus (kidneys—0.191 ± 0.016; liver—0.124 ± 0.011; muscle—0.108 ± 0.009; brain—0.065 ± 0.000). Correlation dependences between Hg content in soil and earthworms ( r s  = 0.85, p  < 0.01) as well as soil and all studied shrews’ organs ( rs  = 0.44–0.58; p  ≤ 0.01) were found. The results obtained evidence for a strong trophic link in the bioaccumulation of Hg in terrestrial food webs. Despite the vicinity to a large metallurgical complex, mercury content in the studied objects was significantly lower than values of corresponding parameters in the soils and biota from industrial (polluted) areas of Great Britain, the USA, and China.
