Numerical simulation algorithmenvironmental risk groups of point sources according undertorch measurements

Purpose. Construction of mathematical models describing the environmental risk from the group of point sources of emissions. Methodology.The methodology includes the following elements: data undertorch measurements carried out in accordance with regulatory document RD 52.04.186-96; PDKk list (or footwear) for all pollutants emitted by a group of sources; design parameters of sources and characteristics of the environment for the worst conditions; regulatory methodology for calculating the concentration in the air of harmful substances contained in industrial emissions (OND-86); Materials predictive environmental risk assessment of the group of point sources of emissions. Findings.Using the resultant mathematical ecological risk assessment model developed algorithm for the numerical solution of the problem. Originality. Using these measurements undertorch determining the actual risk of a simultaneous manifestation of human exposure to emissions of air pollutants from a group of point sources ofindustrial enterprises, depending on the concentrations of pollutants. Practical value. A model for point emission group to assess the actual (according undertorch measurements) environmental risk at the same time the effects of pollutants on humans. Risk assessment model was tested on the example of existing enterprise JSC ?Evraz DMZ them. Petrovsky? (JSC ?Dneprokoks?), Dnepropetrovsk;
