| 摘 要： | 2009年—2010年采暖季、风沙季和非采暖季在西宁市选择了7个环境监测点位采集了大气PM10样品,利用气相色谱-质谱联用技术测定了其中12种多环芳烃的浓度分布特征。结果显示：西宁市采暖期、风沙季和非采暖期三季PM10载带B[a]P的全市平均浓度分别为2.51ng/m3、1.19 ng/m3、1.55ng/m3;PM10载带的B[a]P的浓度与GB3095-1996中规定日平均浓度限值（10ng/m3）相比较,均不超标。

| Abstract: | PM10 samples were collected at 7 atmospheric environmental monitoring points of Xining City during the heating season,the windy season and the nonheating season from 2009 to 2010.The 12 polycyclic aromatic hydrocarbons（PAHs） concentrations were measured using a gas chromatography-mass spectrometry（GC-MS）.The results indicated that the average concentration of B[a]P was 2.51 ng/m3 in the heating season,1.19 ng/m3 in the windy season and 1.55 ng/m3 in the nonheating season.The concentration of B[a]P observed in Xining was generally lower than the limit values of the mean daily standard concentration： 10 ng/m3 stipulated in the Ambient Air Quality Standard（GB3095-1996）. |
