Abstract:
Objective To detect the PM2.5 pollution situation during heating season in Xinxiang university town, analyze the contents of 10 elements in PM2.5, and evaluate its health risks, so as to provide data support for the subsequent environmental governance of college town. Methods PM2.5 were collected during heating season. The contents of 10 elements were detected by ICP-MS after PM2.5 was digested. The source was analyzed using enrichment factor method. The ecological risk and health risk of PM2.5 was evaluated by applying the potential survival hazard index method and health risk assessment method. Results The average contents of Al, Mg, Mn, Cr, Zn, Se, Cu, Pb, Cd and As were respectively 165.59，203.37，7.75，328.93，133.61，8.24，30.82，7.09，2.77and 9.15 ng/m3. The average contents of Cr, Pb, and As all exceeded their air environment targets. The enrichment factors of Pb, Cu, As, Zn, Cd, Cr and Se were all more than 10, and their sources were affected by human activities. The potential ecological risk index of PM2.5 was 352.42, which was strong ecological hazard factor. PM2.5 had carcinogenic risk to human, and the risk in adults was higher than that in children. Conclusion During heating season in Xinxiang college town mainly, PM2.5 may have short-term health risks on environment and human. When the air quality is poor, it is recommended to reduce outdoor activities while taking personal protective measures to minimize the potential health risks to the population in the university town.
