摘要

本研究通过对西北印度洋-甘肃平原（NWIGP）一个具有区域代表性的郊区地点进行全年测量，对 PM2.5 结合金属进行了调查。测得的 PM2.5 结合金属的年平均浓度顺序为 Fe > Zn > Ba > Sn > Pb > Cd > Ni > Mn > Cr > Li。与空气中的 PM2.5 结合的锂是首次在西北印度洋大气污染项目中被报告。镍（72.4 纳克/立方米）和镉（36.9 纳克/立方米）超过了印度 NAAQS 规定的可接受限值。据估计，锰的危害商数（HQ > 1）和所测金属的危害指数（HI > 1）超过了阈值限值，这表明吸入 PM2.5 中的痕量金属可能会带来非致癌健康风险。此外，对吸入接触镉、镍和铬导致的终生致癌风险进行了估算，发现其超过了美国环保局为成人和儿童设定的阈值限值。

Carcinogenicity and non-carcinogenicity health risks due to PM_2.5 bound trace metals at a sub urban site in Northwest Indo-Gangetic Plain.

This study investigates the PM2.5 bound metals using yearlong measurements at a regionally representative suburban site in the Northwest Indo-Gangetic Plain (NWIGP). The order of the measured annual average concentrations of PM2.5 bound metals is Fe > Zn > Ba > Sn > Pb > Cd > Ni > Mn > Cr > Li. Lithium bound to airborne PM2.5 has been reported for the first time in NWIGP. Ni (72.4 ng m-3) and Cd (36.9 ng m-3) have exceeded the acceptable limits set by NAAQS, India. Estimated the hazard quotient (HQ > 1) of Mn and hazard index (HI > 1) of measured metals exceeded the threshold limits indicating the potential non-carcinogenic health risk due to inhalation exposure of PM2.5 bound trace metals. Further, excessive lifetime cancer risk due to inhalation exposure to Cd, Ni and Cr was estimated and found to exceed the threshold limit set by the USEPA for adults and children.

期刊介绍： International Journal of Environmental Health Research ( IJEHR ) is devoted to the rapid publication of research in environmental health, acting as a link between the diverse research communities and practitioners in environmental health. Published articles encompass original research papers, technical notes and review articles. IJEHR publishes articles on all aspects of the interaction between the environment and human health. This interaction can broadly be divided into three areas: the natural environment and health – health implications and monitoring of air, water and soil pollutants and pollution and health improvements and air, water and soil quality standards; the built environment and health – occupational health and safety, exposure limits, monitoring and control of pollutants in the workplace, and standards of health; and communicable diseases – disease spread, control and prevention, food hygiene and control, and health aspects of rodents and insects. IJEHR is published in association with the International Federation of Environmental Health and includes news from the Federation of international meetings, courses and environmental health issues.
