摘要
Exposure to potentially hazardous trace elements (PHTEs) through drinking water consumption can endanger the health of the consumer. In this study, the concentration of Aluminium (Al), Iron (Fe), Copper (Cu) and Manganese (Mn) among 288 water samples were collected (March to February 2016) from water distribution networks of Ilam city was measured using an atomic absorption spectrophotometer (AAS) instrument and the health risk was estimated using the Monte Carlo Simulation (MCS) method. The rank order of PHTEs in the drinking water was Cu (0.200 +/- 0.200 mg/l)> Fe (0.096 +/- 0.094 mg/l)> Al (0.040 +/- 0.060 mg/l) > Mn (0.017 +/- 0.020 mg/l).The rank order of PHTEs based on the non-carcinogenic risk for the adult consumers were Cu (0.250) > Mn (0.0069) > Fe (0.0067) >Al (0.0027) while the corresponding values for children wereCu (0.310) > Mn (0.0087) > Fe (0.0084) >Al (0.0034).The percentile 95% total target hazard quotient (TTHQ) correlated with the investigated PHTEs in the children and adults were equal to 0.3205 and 0.2600, respectively. Therefore, the exposed population is at the acceptable non-carcinogenic risk due to the relatively low concentration of PHTEs in tap drinking water in Ilam city.
