Abstract

Effect of air industrial emissions of the main industrial hubs of Buryatia on the pine forests in water-collecting area of the Lake Baikal has been studied. Contamination of forest stands is estimated from accumulation of sulphur, a priority pollutant element, in needles of Scotch pine. Depending on the distance from sources of industrial emissions, zones of variable intensity of forest pollution are distinguished. The highest correlations between the sulphur content of needles and morphometry parameters of trees are revealed in the zone of severe pollution.
