摘　　要：辽宁省环境监测中心站引进英国的扩散管和监测分析技术,把它应用于室内污染物监测。在沈阳、抚顺两市布 设室内监测点位15个,包括燃煤户和燃气户,监测室内环境中SO2和NO2,调查持续了6个月(每个样品采集时间为一个 月),试验对燃煤户和燃气户结果进行了比较,结果充分体现出辽宁省燃煤加重SO2污染的特点。Liaoning Environmental Monitoring Center carried out a indoor air quality survey using British diffusion tubes and monitoring measures in Shenyang and Fushun where 15 monitoring sites were selected, the concerned pollutants are SC)2 and NO2. The survey lasted 6 monthes (sample action time is 1 month). The basic comparison of the results from coal combustion households and gas combustion households was made and the character that more coal combustion may worsen SO2 pollution in Liaoning area was concluded.
