A questionnaire survey was made to study the opinion of residents in the area of the Yamashev-Dekabristy main road, the joint stock company Tasma-Holding, the commercial joint stock Orgsintez on their health status and on the source of ambient air pollution and the opinion of those living in Gorki-I, an ecologically pure area. The respondents were asked to answer the questions on the unfavourable impact of environmental factors on human health (respondents' painful sensations). The questions also concerned such factors as noise, odour, dust in relation to the place of residence near the main road or an industrial enterprise. The results of the questionnaire survey suggest that environmental pollution exerts an adverse effect on human health particularly in the areas where industrial enterprises and large main roads are located. The findings serve as the basis for introduction of ecological tension-reducing measures.
