Temporal variations 1995 - 2005 for heavy metals, arsenic and PAH in the humus layer in Pasvik and Jarfjord, Finnmark County, Norway

Abstract

Forkortet:\rThe project presented in this report has been supported financielly by the Ministry of the Environment. The report summarizes geochemical analyses of humus samples from Pasvik and Jarfjord in Sør-Varanger in Eastern Finnmark sampled in 1995, 2000 and 2005 together with locations in Karasjon sampeled in 1995 and 2005. Pasvik and Jarfjord have been exposed to the emissions of several metals and arsenic from the smelter in Nikel and ore roasting factory in Zapoljernyi. The Karasjon area 200 km further to the west in central Finnmark functions as an area, which has not been exposed to deposition from the smelter in Nikel. The selected humus samples from 1995 and 2000 sampling campaigns have been reanalysed together with the 2005 samples. Temporal variations for selected heavy metals and arsenic are presented together with PAH concentrations for the three selected areas.
