摘要
于2001年秋季(11月)、夏季(8月)对南京市五大典型功能区的大气颗粒物(PM_(10)、PM_(2.5))进行了监测研究。结果发现,南京市颗粒物污染严重,PM_(10)、PM_(2.5)的超标率分别达到了65％、85％;颗粒物浓度季节变化大,11月污染物浓度明显大于8月,PM_(10)、PM_(2.5)分别相差168.44μg/m^3、190.1μg/m^3;PM_(10)中PM_(2.5)比重较大,大约为75.9％,对人体健康潜在危害大。
Determinations of PM10 and PM2.5 have been carried out at 5 sites of Nanjing in 2001. The results showed that particle pollution is serious in Nanjing, where 65% of PM10 and 85% of PM2.5 are above the Air Quality standards. Pollution in August is more serious than that in November,and the concentration of PM10 and PM2.5, in August is 168. 44μg/m3 and 190. 1μg/m3 higher than that in November, respectively.
About 75. 95 of PM10 is PM2.5 which is dangerous to peoples' health.
