自贡市室内空气污染现状研究

采用现场调查方法，对自贡市不同燃料及建筑类型室内空气污染现状进行研究。结果表明燃煤户室内各污染物浓度高于燃气户，两者比值比二氧化硫（１４．８０）及硫化氢（７．６０）高。苯并（ａ）芘最大日平均值燃气户（６．９０μｇ／１００ｍ＾３）接近燃煤户（７．２５μｇ／１００ｍ＾３）的污染水平。由于受建筑类型的影响，楼房户厨房与卧室的浓度比值大于平房户，其中二氧化硫（３．８３）、苯并（ａ）芘（３．７１）、一氧化碳

The Study of Room Air Pollution in Zi:Gong City

This cross sectional study made a survey on status of room air pollution in the buiding using different fuels with different architeclu ral types in ZiGong city. The result shows each pollutant concentration in room using coal as fuels was higher than that in room using gas, especilly sulfur oxide ration and hydrogen sulfur reached the top level. The maximum daily average level of B(a)p in room using gas was close to that in room using coals. As the factor of the different architectural types, pollutant concentration ration between kitchen and bedroom in storied building was higher than that in one storey building, sulfur oxide ration was 3.83, B(a)p ration was 3.71,carbon monoxide ration was 2.55. Bedroom air pollution in one storey building was higher than that in storied buildig, Comparing with the status of other cities in our country, air pollution of nitrogen oxides in room using gas is still at low level.
