摘要
报告了中美合作“广州市大气污染对儿童肺功能影响研究”课题可吸入性颗粒物的两年监测结果。用安德森双道采样器、Ｔｅｆｌｏｎ膜采集细颗粒物（＜２５μｍ，ＰＭ２５）和粗颗粒物（２５≤＜１０μｍ，ＰＭ２５１０），两者之和为ＰＭ１０，每季度采１５天，每天采一个２４小时样品。结果表明，广州市城区大气可吸入性颗粒物的污染相当严重，尤其是细颗粒物（ＰＭ２５）的污染，应引起公众和政府有关部门的重视。
A two\|year intensive ambient inhalable particulate matters (dp<10umad,PM10) study was conducted in Guangzhou,China in 1995 and 1996.An Anderson dichotomous sampler was operated with Teflon filter membrane to collected fine (dp<25 umad,PM25)and coarse(25dp<10umad,PM25\|10)particles for total mass seasonly.The sampling site were located in the region with busy traffic line in the city(pollution site).The contrast site was located in the relative clear region.The pollution level of the PM25 or PM10 in the pollution site was obviously higher than that in the contrast site.The results indicated that the pollution of inhalable particulate matters in Guangzhou urban region was serious,especially for the fine particles(PM25),and it should cause the attention of the public and the government.
