成都十里店地区冬季大气PM_(2.5)的浓度及重金属含量特征

Analysis of Heavy Metal Content and Concentration Characteristics of PM_(2.5) at Shilidian Chengdu in Winter

随着我国大气污染问题日益严峻,大气环境质量愈加受到人们的关注。由于PM2.5粒径小且毒性大,现已成为大气颗粒物的研究重点。该文以成都理工大学为采样点,于2014年11月进行样品采集,并对PM2.5的重金属污染特征及其中的重金属进行评价,以加深公众对其健康危害的认识。

With the deteriorated pollution situation in China, the air pollution is motioned by more and more people.Due to the small particle size and worse harms of PM2.5 , it became the focus in research.We set chengdu university of technology for sampling points and collected PM2.5 samples in 2014 November.Using potential ecological risk assessment for the heavy metal in PM2.5 . To deepen understanding its greatly potential threat for human health.
