摘要
为探讨以石油液化气为燃料的大庆地区室内空气污染情况,以氮氧化物(NOx)、一氧化碳(CO)及二氧化硫(SO2)为检测指标,对该地区室内空气污染现状及其污染物的浓度变化规律进行了研究。结果表明:液化气燃烧产生的主要污染物是NOx和CO;室内NOx和CO浓度一日间出现二次高峰,高峰时厨房NOx及CO浓度均超过国家标准;厨房内的空气污染物浓度高于卧室;污染物浓度与火苗大小及燃烧时间有关,大火苗时污染最重,燃烧60min后厨房NOx和CO浓度分别超过国家标准15.0和9.4倍,卧室CO浓度超过国家标准1.1倍。
The aim of this study was to investigate indoor air pollution resulting from the combustion of liquefied petroleum gas in Daqing Concentrations of nitrogen oxides(NO x ),carbon monoxide (CO) and sulfur dioxide(SO 2) were determined The results showed that combustion of liquefied petroleum gas could mainly produce NO x and CO contamination The concentrations of NO x and CO reached two peaks daily At peak times,the concentrations of NO x and CO were higher than the national ambient air qualily standard The concentrations of these two pollutants in kitchens were higher than that in bedrooms The concentrations of these pollutants was related to intensity of burning flames and burning time The pollution was the most serious when there were the largest flames,and concentrations of NO 2 and CO after 60minutes combustion were 15 0 and 9 4 times higher than national health standards respectively This study indicated that the levels of NO x and CO in indoor air were potentially harmful to residents' health in this area
