Mercury contamination of bottom sediments in water reservoirs of southern Poland
Journal Title: Geology, Geophysics & Environment - Year 2015, Vol 41, Issue 2
Abstract
The aims of study were to an assessment of mercury concentration in bottom sediments collected from eight reservoirs located in south-eastern Poland. DMA-80 Mercury Analyzer was used for the analysis of concentration of mercury in bottom sediments. Concentration of mercury in sediments was between 0.01 to 0.18 mg ∙ kg-1. The research results showed that average content of Hg in the majority of the studied bottom sediments did not exceed the geochemical background value, the sediments belonged to class 1 (unpolluted sediments). The low mercury content in sediments is related to absent or limited anthropogenic sources of this metal. Evaluation of the state of sediments with the use of the geoaccumulation index and the contamination factor revealed moderate pollution of bottom sediments of the reservoirs in Rybnik, Rzeszów, Ożanna, Brzóza Stadnicka, Brzóza Królewska, Narożniki, Głuchów. Elevated concentrations of Hg in bottom sediments of the reservoirs in Rybnik and Bagna Rzeszowskie are related to their proximity to large agglomerations and industrial plants.
