摘要
采用PS-1型大流量聚氨酯泡沫(PUF)大气采样器,采集了2004年夏季5、6、7三个月广州市区和郊区两个采样点20个大气样品,用气相色谱-质谱联用仪测定了其中16种多环芳烃的含量。结果表明,广州夏季市区和郊区大气中16种多环芳烃(气相和颗粒相)(∑16-PAHs)浓度范围分别为49.33-329.37ng/m^3和30.11-97.97ng/m^3,市区与郊区∑16-PAHs平均浓度分别为144.25ng/m^3和58.79ng/m^3,市区明显要高于郊区;市区和郊区苯并[a]芘(BaP)平均浓度分别为1.17ng/m^3和0.76ng/m^3,均未超过国家空气质量标准。
Totally 20 ambient air samples were collected in the urban and suburban site of Guangzhou between May and July 2004 to investigate the concentration of 16 polycyclic aromatic hydrocarbons ( ∑ 16-PAHs( gas + particle ) ) using gas chromatography - mass spectrometry ( GC -MS). ∑ 16-PAHs concentration in urban ranged from 49.33 to 329.37 ng/m^3 , with the average of 144. 25 ng/m^3. While ∑ 16-PAHs in suburb ranged from 30. 11 to 97.97 ng/m^3 with the average of 58.79 ng/m^3. The average concentration of BaP in urban and suburb were 1.17 ng/m^3 and 0. 76 ng/m^3, respectively, both below the limit of the regulation in China.
