西南某矿区周围环境尘中砷的分布特征分析

Arsenic Distribution of Dust Surrounding the Mine in Southwest of China

探讨有色冶金行业与有色金属采选行业周围环境尘中砷的分布情况。采用原子荧光法对有色冶金及采选行业周围环境采集到的路尘、室外积尘与室内积尘中砷含量进行检测,采用相关统计方法对检测结果进行分析。有色冶金行业与有色金属采选行业周围环境中路尘、室外积尘、室内积尘中砷含量均高于环境背景值;路尘中砷含量水平高于室内积尘中砷含量水平;路尘、室外积尘、室内积尘3种尘中砷含量存在直线关系。加强传播途径中的防护手段能够有效减少砷元素从路尘转移到室外积尘与室内积尘。

To investigate the arsenic distribution of dust surrounding the non-ferrous metallurgical industry and non-ferrous mining industry. Methods Detecting the arsenic concentration of road dust, outdoor dust and indoor dust surrounding the nonferrous metallurgical industry and non-ferrous mining industry by atomic fluorescence spectrometry. Analyzing the results with relevant statistical methods. Result The arsenic concentration of dust surrounding the non-ferrous metallurgical industry and non-ferrous mining industry were higher than background values. The arsenic concentration of road dust were higher than the arsenic concentration of outdoor dust and indoor dust. There is a linear relationship among the arsenic concentration of road dust, outdoor dust and indoor dust. Conclusions Strengthening the means of protection during transmission can reduce the arsenic transferred from road dust to outdoor dust and indoor dust effectively.
