| 中文摘要 |
| 选用聚氨基甲酸酯泡沫塑料(PUFP)吸附块和玻璃纤维滤膜(GF)构成的大气全态采样头,以内蒙古四子王旗草原为对照点,于冬夏两季捕集呼和浩特市(呼市)大气气相和颗粒物中的有机污染物。样品经提取分离后用色质联机(OC-MS)、气相色谱仪(GC)、液相色谱仪(LC)鉴定出3类(烃类、芳烃类、酞酸酯类)近80种有机污染物,对其中45种进行定量分析。结果表明呼市地区属于大气有机污染物高浓度地区。 |
| 英文摘要 |
| Full air samples were collected from the urban area of Huhhot and the grassland belt in Siziwan Qi (a county), Inner Mongolia, as a control site in both winter and summer with a sampler using a Polyurethane foam plug and a glass-fiber filter,both of which were then extracted with solvents. The extracts were analyzed with GC/MS, GC and HPLC to identify the organic Pollutants in both vapor phase and Particulate phase. Eighty eight Pollutants in three kinds of organic compounds (n-alkanes, aromatic njdrocarbons and phthalate esters) were qualitatively identified and 45 of them were quantified. The results show that the Huhhot City is an area polluted with higher concentrations of organic pollutants in the atmosphere in its urban area. |
