Mercury Contamination in Soil, Water, Plants, and Hydrobionts in Kyiv and the Kyiv Region

In this paper, there was investigated the content of mercury in soil, plant, water, and hydrobionts in Kyiv and in the Obukhiv district of the Kyiv region. Studied territory is characterized by high anthropogenic load. The solid waste landfill in the Obukhiv district of the Kyiv region was characterized by the highest content of Hg in soil. Hg concentration in Taraxacum officinale L. was the highest among all studied plants, hence the possibility of recommending this species for phytoremediation of mercury-polluted soils. Mercury bioaccumulation of aquatic organisms (Blicca bjoerkna L., Esox lucius L., Ceratophyllum demersum L.) was much higher than in terrestrial organisms, which indicates the significantly prevailing level of availability and accumulation of mercury for aquatic species in the water environment.
