空气不同粒径颗粒物中重金属分布特征及其影响因素分析

Distribution Characteristics and Influencing Factors of Heavy Metals in Air Particles with Different Particle Sizes

针对空气中重金属含量逐年增多问题,且重金属元素在空气中不能降解,以河北铅锌矿区为例,对空气不同粒径物中重金属分布特征以及影响因素进行分析。在河北省各监测区域的空气监测过程,以Pb、Zn、Cu、Hg、Cr等重金属元素为研究对象,记录其不同位置空气重金属含量,分别与铅锌矿区空气重金属含量作对比,记录对比分析结果。实验证明,河北省一年之中冬季和秋季空气中的重金属含量较低,从夏季开始空气中重金属含量不断提高,春季空气中的重金属含量最高;化工厂越多的地区空气中的铅和镉含量越高。

The heavy metal content in the air is increasing year by year, and the heavy metal elements in the air can not degradation in Hebei lead-zinc mining area as an example, the air of different size in the distribution characteristics of heavy metals and influencing factors. In the process of air monitoring of the monitoring area of Hebei Province, Pb, Zn, Cu, Hg, Cr and other heavy metals as the research object,record the different position of air heavy metal content, respectively compared with the air content of heavy metal Pb Zn mine, record the results. Experiments show that Hebei province a year of heavy metal content in winter and autumn in the air is low, from the beginning of the summer heavy metal content in the air spring in the air increases, the highest concentrations of heavy metals; lead and cadmium content in chemical plant more areas in the air is more high.
