Health Risk of Polycyclic Aromatic Hydrocarbons – PAHs in Primary School Environment in Serbia, Probabilistic Modeling Study

Polycyclic aromatic hydrocarbons (PAHs) are a group of organic compounds and many of them are toxic and carcinogenic environmental contaminants. They typically result from the incomplete combustion processes of organic materials. Exposure to PAHs emissions can create a number of adverse health effects. Children represent one of the most susceptible population groups with regard to potentially harmful effects. The main objectives of this paper are: first, experimental evaluation of concentrations of 16 priority PAHs in indoor and outdoor air in Serbian school, where residential heating and traffic are the only major PAH sources. The second objective is calculation of cancer risk of PAHs for children from total suspended particles (TSP) using suggested incremental lifetime cancer risk (ILCR) model based on Monte Carlo simulations. The obtained measured values as well as calculated numerical results showed, that although PAHs concentration values are lower than suggested limits, additional care should be taken in order to further decrease children cancer health risk of PAHs’ emissions.
