摘要
采用静态雾水采集器,在距新疆乌鲁木齐市58 km的南山地区白杨沟海拔1 922 m处,进行连续间隔采样,研究其化学成份、分析其成因及对南山原始植物林带的影响。结果表明南山白杨沟地区SO42-、NO3-、Cl-浓度(7171、22、265μmol/L)远高于较清洁的景洪、舟山、庐山等地的值。且五月SO42-、NO3-、Cl-浓度远高于3、4月的值,可认为南山白杨沟地区已开始受到人为污染,雾对其周围环境有害而无利。
Nanshan with an elevation of 1?922 m is located at 58 km from Urumqi,the chemical compositions of the fog sampled in Nanshan by passive fog collector were analyzed,and the contributing factor and influence on the environment were discussed.The results showed that the concentration of SO_4^(2-)、NO_3^-、Cl^-were 717?μmol/L,122?μmol/L,265?μmol/L,respectively,and they were much higher than other cleaner regions(including Jinghong,Zhoushan,Lushan,etc.).The concentrations of SO_4^(2-)、NO_3^-、Cl^-in May were much higher than March and April.It was clear that Nanshan area had been polluted by the fog.
