Abstract

Recent work on atmospheric pollution and its effects on surface waters has focused mainly on areas receiving high acid deposition. There is now increasing interest in the effects and extent of atmospheric contamination in background areas outside these regions not only to establish impacts of long distance pollutant transport but also to identify undisturbed ecosystems where responses to future climatic change might be best detected. Recent developments in the former Soviet Union (FSU) have facilitated access to remote regions of Eurasia where recent environmental change impacts on natural ecosystems are poorly known. The Khamar Daban Mountains in SE Siberia is one remote region that lies in the main trajectory paths of polluted air masses from industrialized centres in Europe. Investigation of the effects of atmospheric pollution in this region is important for several reasons but especially because it contains the world's largest undisturbed boreal wilderness aiea". Recent sedimentary records from two high mountain soft-water lakes in this mountain range are used to reveal the regional extent and timing of atmospheric contamination and environmental change. This report details the first palaeolimnological investigation of sensitive mountain lakes in Central Asia and demonstrates the value of these techniques in identifying trends in environmental change over recent decades at remote, unmonitored and uqsurveyed sites.
