摘要
近年来,雾霾天气频繁发生,大气污染已引起世界范围的殷切关注;并且成为世界共同研究的课题,其中细颗粒物污染已成为首要问题。而伴随着生活方式的转变,人们越来越注重室内空气品质,因此,室内PM_(2.5)污染已成为亟需解决的问题。通过分析室内PM_(2.5)污染来源以及对人体健康的影响,进行了关于室内PM_(2.5)暴露水平影响的实验研究。结果表明,吸烟是室内PM_(2.5)的主要来源;吸烟时会使室内PM_(2.5)暴露水平显著升高;烹饪会使室内PM_(2.5)暴露水平严重超标;人员活动产生的细颗粒物强度取决于室内的人数、活动类型、活动强度等;室内PM_(2.5)暴露水平受室外影响较大,呈现明显的正相关性。
In recent years,the fog and haze occurs frequently,air pollution has caused great attention worldwide,and become the world＇s common research subject,particulate matter pollution has become the primary problem. With the change of life style,people pay more and more attention to the indoor environment quality. Indoor particulate pollution has become an urgent problem to be solved. Through the analysis of the main sources and effects on human health of PM（2.5）pollution in the building,the experimental study on the impact of the pollution sources on the indoor PM（2.5）exposure level is carried out. The results showed that smoking is the main source of indoor PM（2.5）. Smoking can make indoor PM（2.5）exposure levels were significantly increased. Cooking can make indoor PM（2.5）exposure exceeds the standard. The intensity of fine particulate matter is determined by the number of persons,activity type,activity intensity,etc. Indoor PM（2.5）exposure level is greatly influenced by the outdoor environment,present obvious positive correlation.
