| 中文摘要 |
| 对大同市不同功能区的可吸入尘(<10μm)浓度进行了测定,并探讨了可吸入尘与总悬沙颗粒物的相关比例。总悬浮颗粒物上二氯甲烷萃取物的含量达20%。对其中的有机污染物用GC/MS和HPLC进行了分析,鉴定出的主要有机污染物有本系物及芳烃类化合物38种,烷烃类化合物31种,以及酚类、酮类、含氮化合物和增塑剂14种,总计83种。 |
| 英文摘要 |
| This paper reports the determination of atmospheric particulates from different functional districts in Datong. The inhalatable particulates (M 10μm)concentration accounts for about 50% of the total suspended particulates(TSP).The extracts in methylene chloride representing the total polluted organic materials account for about 20% of TSP. The compounds in the total polluted organic materials identified with GC,GC/ MS and HPLC included 38 compounds of benene series and other aromatic hydrocarbons,31 compounds of paraffins,and 14 compounds of phenols, ketones,nidrogencontaining organic and phthalates. |
