SOIL MONITORING IN THE ZONE OF INFLUENCE OF ASPHALT-CONCRETE PLANT
This article deals with the contamination of soils by oil products, chloride ions and heavy metals in the territory of the asphalt plant. The analysis of soil samples for the content of heavy metals was carried out by gravimetric and fluorometric methods. The soil is able to absorb technogenic impurities and also accumulate contaminants, including heavy metals, which, if excess, exhibit toxic properties, slowly breaking down under natural conditions and entering the cycle of trophic chains. The analysis of the selected soil sample was carried out in the laboratory of environmental monitoring of physico-chemical pollution of the environment in Birsk, Republic of Bashkortostan. Research shows there is an excess in majority of the investigated parameters are observed in the territory of the asphalt plant. The totality of the results of the soil state study in the area adjacent to the asphalt plant revealed a considerable level of soil contamination corresponding to significant degree of technogenic depletion. In its turn it speaks of the operation of technological equipment and a long working life.
