Bioindicative assessment of the urban environment quality

The article analyzes the environment in Murmansk by complex of traits of conifers. In the areas with high anthropogenic load of the vehicles it studies deviations in the development of needles and shoots of Larix sibirica L. In the study traced the stability of Larix sibirica L. to pollution (average percentage area damaged needles to 22.5%). In the areas with high anthropogenic load we recorded a large area of damaged needles in comparison with the control object. The number of needles that are prone to damage of different types varies in the range of 31 to 38% in the areas with high density of vehicles. In the areas close to the highway we found the samples with drying of more than 30 - 50% of the area of needles. The calculation of the hemispherical and the total surface area of needles shows that in the areas with high anthropogenic load the area is by times smaller than in the areas with low density of vehicles. The data obtained in the study allow us to identify the negative trends associated with the systematic pollution of atmospheric air on the territory of Murmansk and propose the ways to improve the air quality monitoring system at the regional level.
