| 中文摘要: |
| 通过对浦东新区9个点位PM2.5中的多环芳烃为期1 a的采样分析，获得浦东新区PM2.5中PAHs的时空变化特征。监测表明，冬季PAHs的浓度为夏季的7.9倍，空间上南部偏高；虽然不同季节不同环数的PAHs浓度变化存在一定差异，但均为5～6环占比最大，其次为4环，2～3环占比最少。结合PAHs呼吸致癌风险评估，浦东新区PAHs致癌风险值分布与实际肺癌发病率分布在冬季具有相关性。 |
| 英文摘要: |
| The spatial and temporal variation of PAHs in PM2.5 from 9 monitoring sites in Pudong area was observed through one year sampling and analyzing. The concentration of PAHs in winter was 7.9 times of that in summer. There was a high level of PAHs concentration in the south of that area. Though the concentrations of different rings PHAs were not the same in different seasons, 5~6 rings PHAs were the in the majority, 4 rings was subsequent and 2~3 rings were the least. According carcinogenic risk assessment, the risk value of PHAs in Pudong New area was correlated with the incidence of lung cancer in winter. |
