Název v původním jazyce

A long-term survey of heavy metals and specific organic compounds in biofilms, sediments and surface water in a heavily affected river in the Czech Republic

Popis výsledku v původním jazyce

To assess the long-term anthropogenic load of the Bílina River (Czech Republic), the concentrations of heavy metals and specific organic compounds in different river ecosystem matrices (water, biofilms and sediments) were determined. Although the currentconcentrations of pollutants in surface water are low, frequently below the limits of the quantitative analytical methods used, the river ecosystem is still heavily loaded by anthropogenic pollution, mainly from the chemical and mining industries. Thiswas demonstrated by analyzing biofilms and sediments. These matrices are more accurate representatives of the actual situation in the river, and do not depend on hydrological conditions or random variability in water quality. The results indicate that the middle and the lower parts of the river are heavily polluted by mercury, arsenic, vanadium, polychlorinated biphenyls, hexachlorobenzene and dichloro-diphenyl-trichloroethane.
