东北农村居住建筑冬季室内空气污染研究

Study on indoor air pollution in rural residential buildings in northeast China in winter

在吉林省两个具有代表性的自然村中,选取4位农户和2个超市,对其冬季室内空气污染物浓度进行了连续实时监测,并分析了炊事、取暖、人员密集度和吸烟等不同因素对室内空气污染物浓度的影响.结果表明,由燃烧秸秆炊事、取暖产生PM 2.5约为由燃煤产生PM 2.5的1.18~15.08倍,相应产生的CO 2约为2倍,而人员密集度和吸烟则均会引起室内空气污染物浓度升高.

In two representative natural villages in Jilin province,4 farmers and 2 supermarkets were selected to continuously monitor the concentration of indoor air pollutants in winter,and the influences of cooking,heating,concentration of people and smoking on the concentration of indoor air pollutants were analyzed.The results showed that the PM 2.5 generated by straw cooking and heating was 1.18~15.08 times that generated by coal burning,and the corresponding CO 2 generated was about 2 times,while the concentration of people and smoking both caused the concentration of indoor air pollutants to increase.
