Hodnocení imisní zátěže v okolí cementárny a vápencového lomu

Abstract

This paper deals with the assessment of the ambient air pollution in the surroundings of the limestone quarry and cement plant in Hranice based on the analysis of dust fall and road dust. The results show that the area is not polluted by increased emissions, except for local increases in the vicinity of the limestone quarry. The composition of the dust fall shows a dominance of natural, siliceous particles and reveals no influence of the cement plant. A particle size analysis of the road dust revealed a higher particle frequency in the vicinity of the quarry, accompanied by an increased concentration of calcium. In the grain size class of road dust <0.063 mm, the enrichment factor revealed considerable to very heavy contamination with zinc and above all copper, mainly caused by traffic. The local occurrence of elevated calcium concentrations in road dust suggests that the influence of the cement plant and mining is spatially limited to a radius of about 2 km. Significant zinc or, in the case of copper, very heavy pollution.
