摘要
通过对成都市城乡结合部的大气水进行定点周期性采集和监测,并采用火焰原子吸收光谱法和原子荧光光度法测定样品中表征大气水样受污染程度的重金属含量,包括Cu、Pb、Fe、Mn、Zn、Cd、Hg、As、Cr等9种重金属元素。分析结果表明,成都市城乡结合部大气水中主要污染重金属元素为Cu、Zn、As、Hg、Fe,其中Hg、As含量在秋冬季以及阴雨雾霾的特殊天气条件下尤其高,东郊监测最高As浓度为12.86mg/L,西郊监测Hg浓度高达17.55mg/L。从区域污染程度上说,西郊大气水重金属污染较为严重,东郊较之稍轻。
The atmospheric water samples were periodically collected and monitored in the suburb of Chengdu,the concentration of Cu,Pb,Fe,Mn,Zn,Cd,Hg,As,Cr in the atmospheric water were analyzed with flame atomic absorption spectrometry(FAAS)and atomic fluorescence spectrometry(AFS)methods.The results showed that the main contaminative heavy metal elements in the atmospheric water were Cu,Zn,As,Hg,Fe in the suburb of Chengdu,the concentrations of Hg and As were apparently higher in fall and winter,in the rainy,foggy a...
