Determination of the foundry environmental threat coefficient

The state of the working area in the foundry sections is determined predominantly by the number of pollutant sources and the state of air cleaning devices. Organized pollutant emissions in the atmosphere are implemented by low pipes, unorganized pollutant emissions are implemented through ventilation chambers of exhaust ventilation system. The emission amounts and their toxicity determine the category of an enterprise as the atmosphere pollution source. An analytical method of determination of ecological risk coefficient is developed on the basis of available methods for estimation of emissions effect on the atmosphere.
