摘　　要：2001年到2002年,在太原市5个采样点分别采集了环境空气中的总悬浮颗粒物(TSP)和可吸入颗粒物(PM10)。用化学质量平衡模型和二重源解析技术解析了TSP和PM10的来源,结果表明,各主要源类对TSP的分担率依次为燃煤尘28%、扬尘24%、建筑水泥尘14%、硫酸盐10%、机动车尾气尘10%、土壤风沙尘5%、钢铁尘4%、硝酸盐4%、其它1%;对PM10的分担率依次为扬尘30%、燃煤尘18%、机动车尾气尘15%、硫酸盐11%、土壤风沙尘9%、建筑水泥尘7%、硝酸盐4%、其它1%。The total suspended and inhalable particulate matter(TSP and PM10) samples in environmental air were collected respectively in 2001-2002 at five sampling sites in Taiyuan.The sources of TSP and PM10 were analyzed with chemical mass balance(CMB) receptor model and nested chemical mass balance(NCMB) technique.The result showed that the major sources of TSP were in the order of coal combustion dust 28%,suspended dusts 24%,cement dusts 14%,sulfate 10%,motor vehicle exhausts 10%,soil wind sand dusts 5%,steel dusts 4%,nitrate 4%,others 1%.The major sources of PM10 were in the order of suspended dusts 30%,coal combustion 18%,motor vehicle exhausts 15%,sulfate 11%,soil wind sand dusts 9%,cement dusts 7%,nitrate 4%,others 1%.
