Hydrobiological implications and method for determining the dust pollution of nival-glacial systems

Abstract

The global pollution is one of the main causes of degradation of nival-glacial systems. The consequences of this process have been studied on the example of alpine lakes of the Big Zelenchuk Basin. It has been found that the dusting of snow and ice led to an adequate increase of mineralization of alpine lakes. The accumulation of chemicals has been marked in the silt lakes. As a result of the increase in mineral fodder in these lakes, the phytoplankton productivity level has increased to visually noticeable quantities. Beetles, caddisfl ies and other aquatic animals have become numerous. These circumstances allow developing of a new method for remote determination of the degree of dust contamination of nival-glacial systems by assessment of the water color in alpine lakes
