Abstract:

Analysis of air quality in the city of Niš indicates a presence of increased concentrations of pollutants in outdoor air. In the period from 2019 to 2023 air quality in the area of the city of Niš was in the category of excessively polluted air, because of increased concentrations of PM10 and PM2.5 particulate matter. Multiple exceedances of the limit and tolerance values of PM10 and PM2.5 particulate matter are the basis for the emergence of a health risk that manifests itself through various types of pathological conditions. The physicochemical properties and chemical composition of PM10 and PM2.5 particulate matter are the criteria for classifying these particles as carcinogenic substances. This paper presents the probability of the occurrence of cancerous diseases during exposure to suspended PM10 and PM2.5 particles. The risk of cancer development (Ri) was determined based on intake dose and unit risk. The calculated probability is in the range of the level of possible and the level of probable carcinogenic risk, depending on the length of exposure. The probability was determined using the methodology provided by US EPA..

Keywords:

PM10 and PM2.5 particulate matters, health risk, cancer risk, unit risk, exposure
