日本关东南部冬季飘尘中有机碳和元素碳污染现状研究

Investigation of the Pollution of Organic Carbon and Elemental Carbon in Winter SPM of South Kando of Japan

气溶胶中常含有一定的碳化合物,其中最主要的为有机碳(OC)和元素碳(EC),它们主要来源于化石燃料燃烧等人为活动,并强烈地影响着气溶胶的污染性质。日本关东平原南部初冬季节常发生高浓度飘尘污染,在对这种污染现象的研究中分析了OC和EC在飘尘中的含量,结果表明OC和EC是飘尘中重要的组成部分,二者之和可占质量浓度的20%左右,这也从一个侧面揭示了飘尘的污染状况和污染来源。

There are carbonic compounds in aerosol, Usually the main carbonic compounds are organic carbon (OC) and elemental carbon (EC). They come from human activities, such as the uses of fossil fuel and add much to the nature of aerosol pollution. In early winter, Kando plain in the South of Japan has high concentration of SPM. The concentrations of OC and EC in the SPM were analyzed and were found to be the main components of the SPM. The two components weight about 20% of the SPM. This also revealed the pollution condition and source of the SPM.
