Abstract

Lake sediments provide a record of aunospheric contamination and have been important in recent studies of lake acidification. Carbonaceous and mineral ash particles derived from fossilfuel combustion are found in considerable numbers in upper levels of lake sediment cores taken from areas with high acid deposition. Sites in the United Kingdom show close correlation between the onset of aunospheric contamination as indicated by carbonaeeous particles, heavy metals and magnetic deposition and the acidification of lakes as indicated by diatom analysis (Battarbee et al. 1988). Studies in progress seek to examine the aunospheric record provided by mineral ash spheres in lake sediments.
