成都市大气颗粒物的特性研究

以成都市东区为研究区域，研究了该区总悬浮颗粒物（哪）含量及其中重金属的含量随季节变化的特征，通过粉煤灰与哪中重金属含量的关系、富集因子分析来判断颗粒物中重金属的来源。研究表明，TSP及其中重金属的含量随季节变化明显且特征相似；哪的含量严重超标；由监测结果大致推断出了该区域哪及其中重金属的主要来源。

Research on Characteristic of Particles in the Air of Chengdu

Based on the east district of Chengdu, the characteristic of the density of total suspended particles and heavy metals in it changed with the seasons was researched. Through the relevance analysis between the density of heavy metals in TSP and fly dust, the origin of heavy metal in TSP could be judged. The research indicated that the density of TSP and heavy metals in it changed with the seasom abviously, and the characteristic was similar; the density of TSP went beyond the standard greatly; the main origin of TSP and heavy metals in it could be approximately inferred from the respecting results.
