Ambient Air Pm2.5 Particulates And Pollutants (Cr, Ni, Cd, Pb, Hg(P), Tgm, Rgm, Gem) Concentrations And Health Risk Assessment Study Nearby An Airport in Central Taiwan
This study discussed the ambient air PM2.5 and associated pollutant (Cr, Ni, Cd, Pb, Hg(p), TGM, RGM, GEM) concentrations and health risks of residents living nearby an Airport in central Taiwan. The sampling program was conducted during Sep. of 2016 ~ Feb. of 2017. PM2.5 was measured by using a Wilbur PM2.5 sampler. Metallic elements (Cr, Ni, Cd, Pb) were analyzed by using the ICP-OES analyzer. The results indicated that the average concentration of PM2.5 was 23.2 μg/m3In addition, the autumn has the highest mean mass, Cr, Ni, TGM, GEM and RGM concentrationswhilethe winter has the highest mean Cd, Pb and Hg(p) concentrations. Finally, the carcinogenic risks via inhalation exposure to Cr, Ni, and Cd in PM2.5 for children and adults were higher than 1 ×10-6 set by the US EPA. The calculated non-carcinogenic risk (Cr, Ni, Cd, GEM and Hg(p)) was below 1..
