为了调查夏季南昌市大气颗粒物PM_(10)·PM_(2.5)的污染水平,在2007年7～8月在南昌市5个典型城市功能区采集了80个样品.结果表明,南昌市PM_(10)和PM_(2.5)污染很严重,超标率分别达55%和60%,而且对人体健康危害更大的PM_(2.5)所占比例较大,约为65%;在空间分布上,夏季5个采样点的污染情况基本为交通干线>工业区>商业混合区>居住区>远郊区,南昌市大气颗粒物中PM_(10)、PM_(2.5)的回归方程为PM_(2.5)=0.545 9PM_(10),相关系数为0.998 3.
為瞭調查夏季南昌市大氣顆粒物PM_(10)·PM_(2.5)的汙染水平,在2007年7～8月在南昌市5箇典型城市功能區採集瞭80箇樣品.結果錶明,南昌市PM_(10)和PM_(2.5)汙染很嚴重,超標率分彆達55%和60%,而且對人體健康危害更大的PM_(2.5)所佔比例較大,約為65%;在空間分佈上,夏季5箇採樣點的汙染情況基本為交通榦線>工業區>商業混閤區>居住區>遠郊區,南昌市大氣顆粒物中PM_(10)、PM_(2.5)的迴歸方程為PM_(2.5)=0.545 9PM_(10),相關繫數為0.998 3.

In order to investigate pollution levels of airborne particulate matter PM_(10) and PM_(2.5) at the summer in Nanchang City, eighty airborne particulate samples were collected at five typical function areas of Nanchang City from July to August in 2007.The results indicated that the pollution by PM_(10) and PM_(2.5) was quite serious .The rates exceeding the standard were 55% and 60% respectively.PM_(2.5) fraction, which was more harmful to human health, accounted approximately 65%. The pollution of five sampling site was traffic route> industrial zone > business mixing zone> residential area> outer zone. The regression equation of PM_(10) and PM_(2.5) particulate matter in Nanchang was PM_(2.5)=0.545 9PM_(10), and correlation coefficient was 0.998 3.
