Abstract
The paper presents the estimation of the ecological risk from atmosphere pollution by the practical activities of the metallurgical factory OJSC «EVRAZ ZSMK» from all organized and unorganized emissions sources of manufactories: ore-preparation, agglomeration, blast furnaces, steel-smelting, rolling and foundry. It has been shown, that non-carcinogenic ecological risk of chronic intoxication is not higher than acceptable level of 75 % from all the organized sources (208 items), high risk – of 22.1 %, very high – of 2.9 %. Non-carcinogenic ecological risk from all unorganized sources (39 items) is higher than the acceptable level in 40 times. To reduce organized emissions it has been proposed to increase the height of the pipes in manufactories of ore-preparation, agglomeration and blast furnaces, to control of nose section of the Venturi’s tube and cyclone SIOT in manufactories of steel-smelting, rolling and foundry. The proposed recommendations of technological methods are cost-effective and will allow reducing the content of airborne hazardous substances and closing to achieving optimal working conditions (first class).
