石家庄市冬季大气中TSP，PM10，PM2.5污染水平研究

为研究石家庄市冬季大气颗粒物污染特征,于2013年2月采集TSP,PM10,PM2.5样品,用重量法分析其质量浓度,并对其相关性进行分析。结果表明,用环境空气质量标准(GB 3095-2012)来衡量,石家庄市冬季大气颗粒物TSP,PM10和PM2.5的日均浓度超标率分别为57.9%,82.9%和81.6%;超标倍数分别为1.28,1.86和2.24倍,超标情况严重;TSP与PM10和PM10与PM2.5相关系数分别为0.748 9和0.760 4,相关性较好;ρ(PM10)/ρ(TSP)平均值为0.74,ρ(PM2.5)/ρ(PM10)平均值为0.61,表明PM10和PM2.5污染严重。

Research of TSP, PM10 and PM2.5 pollution level in Shijiazhuang winter atmosphere

To study winter atmospheric particulate matter pollution characteristics of Shijiazhuang City,TSP,PM10 and PM2.5samples were collected in February 2013.Its mass concentration was analyzed by weight method,and its relevance was analyzed.Results show that using the ambient air quality standard(GB 3095-2012)as reference,Shijiazhuang winter atmospheric particulates pollution is serious,and TSP,PM10 and PM2.5daily average concentration are 57.9%,82.9%and 81.6%,respectively,and excessive multiples are 1.28,1.86,and 2.24 times,respectively.The correlation coefficient between TSP and PM10 and the correlation coefficient between PM2.5and PM10 are 0.748 9and 0.760 4,respectively,showing the correlation is good;the PM10/TSP average is 0.74 and the PM2.5/PM10 average is 0.61,which shows that atmospheric particulate matter PM10 and PM2.5pollution are serious in winter in Shijiazhuang City.
