2003年7月、8月以及11月至2004年1月,在北京大学物理楼顶(北纬39.99°,东经116.31°)使用两台黑碳仪(Aethalometer)和一台TEOM1400a(Tapered Elemnt Oscillating Microbalance)来观测气溶胶.得到夏季黑碳的平均浓度为8.800 μg·m-3,冬季为11.400 μg·m-3.在冬季的观测中,在一台黑碳仪的进气口加上不同的切割头,分别得到了全部气溶胶(TSP)、PM10以及PM2.5中的黑碳质量浓度.结果表明,北京冬季的气溶胶中,90%的黑碳存在于PM10中,82.6%的黑碳存在于PM2.5中.比较PM10的浓度和PM10中黑碳的浓度可以看出,PM10中黑碳质量平均占5.11%.国家重点基础研究发展计划(973计划)中文核心期刊要目总览(PKU)中国科学引文数据库(CSCD)0117-222
