Abstract

A multimedia sampling of ambient air, wet deposition, surface water, sediment, soil, and biota has been performed at Kosetice background observatory in the southern Czech Republic since 1988. Integrated monitoring approach was applied to assess the current state, anthropogenic impacts, and possible future changes of terrestrial and freshwater environments. Average PCB concentrations in the individual matrices calculated from ten years of sampling on multiple sites varied between 2 ng g-1 in sediment and 7 ng g-1 in soil or moss. DDT concentrations were lower in moss and needles (2 ng g-1 and 4 ng g-1, respectively) than in sediment (11 ng g-1) and soil (20 ng g-1) while HCH level was higher in moss and needles (5 ng g-1 and 6 ng g-1, respectively) than in soil or sediment (1 ng g-1 and 2 ng g-1, respectively). Highest average level of PAHs was found in soil (600 ng g-1) while it was lower in needles (230 ng g-1), moss (210 ng g-1) or sediment (210 ng g-1). Time related trends of concentration levels of persistent organic pollutants in all matrices were investigated. Moss and needle trend patterns resembled those of the ambient air, showing a slight concentration decrease of all compounds except for hexachlorobenzene. The soil, water and sediment concentrations showed similar decrease of PAHs, PCBs, and HCHs, but there was no clear trend for DDTs and HCB.
