ABSTRACT
At present a waste incineration in households is a great problem. In municipalities with established separate waste collection, the question about waste recovery is partially resolved. In municipalities where separate waste collection is not possible or is not established, citizens use mainly combusted waste as alternative fuel for domestic boilers. Air quality declines especially in winter period of the year. In local house boilers are combusted common fossil fuels (natural gas, lignite, coal, wood, biomass) but also household waste, for example plastic waste, paper, paper and plastic packaging covers, rubber materials etc. Municipal waste contains heavy metals and many hazardous substances as shown in chemical analysis, which are resources of air pollutant emissions. From house stacks, these are emitted to free atmosphere. By chemical analysis of common household wastes we can calculate emission rate for existing pollutants. Using the air quality models, respectively air dispersion models we can calculate local air quality on local level. This article deals with the model calculation of air pollution by emissions of heavy metals (As, Cd, Cr, Cu, Hg, Pb, Sb) produced from uncontrolled waste incineration in small house boilers. By dispersion models we can calculate expected air quality for standard fossil fuels and household waste.
