源解析模型在中国大气颗粒物重金属来源分析中的应用研究

A Study on Application of Source Apportionment Model in China 's Atmospheric Particles Heavy Metals

大气颗粒物中的重金属除直接通过呼吸、皮肤接触直接进入人体,还能够在干湿沉降作用下进入土壤和水体,并通过食物链危害人体健康.通过文献调研分析了中国大气中重金属污染状况及暴露特征,综述目前国内几种常用的大气颗粒物中重金属源解析方法,并提出应加强源解析模型的综合应用,建立排污标准.

Through breathing and skin exposure,heavy metals in atmospheric particles can enter human body directly,and they can also enter the soil and water under the effect of dry wet sedimentation,produc-ing harms for human health through the food chain. This paper analyzes the current situation of contamina-tion and exposure,and it also summarizes several commonly-used sources apportionments of heavy metals in atmospheric particles. Finally,it presents comprehensive application of source apportionment model and e-mission standards.
