摘要
采集了5个不同区域的空气冷凝水样品,检测了其化学成分。结果显示,空气冷凝水的化学成分在不同区域存在着明显差异,5个区域各类化学物质总量的关系是,阴阳离子:城区>工业>道路>城郊>景区;微量元素:工业>城区>道路>景区>城郊;总有机碳(TOC):城区>景区>道路>工业>城郊;总无机碳(TIC):景区>城区>道路>工业>城郊;物质总量:城区>工业>道路>景区>城郊;其质量浓度分布与区域内的空气污染状况密切相关,大部分物质的质量浓度日间低于夜间。
The air condensate water samples were collected in 5 urban regions. The results showed that there were significant differences in chemical components of the air condensate water in different regions; their concen-tration sequence between the five areas were, the sum of anions and cations： downtown area 〉 industrial district 〉 road 〉 suburb 〉 scenic area; the sum of microelements： industrial district 〉 downtown area 〉 road 〉 scenic area 〉 suburb ; TOC ： downtown area〉 scenic area 〉 road 〉 industrial district 〉 suburb ; TIC ： scenic area 〉 downtown area 〉 road 〉 industrial district 〉 suburb ; the sum of chemical substances ： downtown area 〉 industrial district 〉 road 〉 scenic area 〉 suburb ; there was the affinity between the concentration of analytes and the condition of air pollution in atmosphere regions, and the concentration of majority analytes were lower in daytime than at night.
