The aim of the present study was to evaluate the health risk of potentially toxic elements (PTEs) As, B, Cr, Cu, Mn, Ni and Zn in electrofilter ash (EFA) and fly ash (FA) from chronosequential FA lagoons L0, L1 and L2 (with weathering and revegetation duration of 0, 3 and 11 years, respectively) for the health of residents (children and adults) in the vicinity of Nikola Tesla A Thermal Power Plant (TENT A), Obrenovac, Serbia. Namely, spreading FA on the surrounding agricultural land, roadside and residential areas may expose the surrounding population to the harmful effects of PTEs and endanger their health through direct ingestion, dermal contact or inhalation. Health risk analysis has shown that oral ingestion of EFA and FA poses the highest potential risk to both adults and children. Children are more susceptible to the health effects of PTE compared to adults, and As poses a potential noncarcinogenic risk to children from ingestion, especially in the case of EFA and raw FA from L0 , while the noncarcinogenic risk potential of Cr in EFA is present in both children and adults. The cumulative noncarcinogenic effect of all tested elements was present in children in the case of ingestion of both EFA and FA from L0 and L1, while for adults only in the case of ingestion of EFA. On the other hand, the carcinogenic risk of EFA and FA from all lagoons was within acceptable limits. The results of this study could be useful to obtain basic information about the health risk status of people living in these areas.
