济南市环境空气中TSP和PM10来源解析研究
Study on Source Appointment of TSP and PM10 in Air Environment in Jinan
-
摘要: 于1999—2000年在济南市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(CMB)受体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的贡献率依次为:扬尘34%,煤烟尘25%,土壤风沙尘18%,机动车尾气尘6%,建筑水泥尘2%,其他15%;对PM10的贡献率依次为:扬尘30%,煤烟尘27%,土壤风沙尘15%,机动车尾气尘9%,建筑水泥尘3%,其他16%。Abstract: Samples for TSP and PM10 were collected from 1999 to 2000 at five sites in Jinan.The authors investigated the contributions of emission sources to TSP and PM10 in Jinan by chemical mass balance (CMB) and nested chemical mass balance(NCMB) receptor models.The results showed that the major contributors of TSP in Jinan include:urban resuspended dusts 34%,coal combustion 25%,soil dusts 18%,motor vehicle exhausts 6%,cement dusts 2% and unexplained mass 15%.The major sources of PM10 aerosols are:urban resuspended dusts 30%,coal combustion 27%,soil dusts 15%,motor vehicle exhausts 9%,cement dusts 3% and unexplained mass 16%.
