Abstract
Sediments from two naturally acid lakes have been used to investigate whether there is any local impact of atmospheric pollution from an oil refinery at Mongstad in Western Norway. The refinery started production in 1975 and expanded in 1987. One lake was selected as a reference site as it only receives long-range transported air pollution, whereas a second lake was selected as it was expected to receive both long-range transported and local air pollution from the refinery. Heavy metal (Pb, Ni and Zn) and spheroidal carbonaceous particle (SCP) (> 5 µm in diameter) concentrations and accumulation rates have been estimated and lake-water pH has been reconstructed by weighted averaging and weighted averaging partial least squares regression and calibration from the fossil diatom assemblages.
