摘要
从浓度水平、化学成分、变化规律和健康危害4个方面调研了我国室内空气细颗粒物(PM_(2.5))的污染现状。结果表明:我国城市和农村都存在不同程度的室内PM_(2.5)污染现象,部分城市室内PM_(2.5)浓度均值高达(764±71)μg/m3,化学成分中镉、砷等重金属元素和苯并(a)芘(BaP)超标严重。分析了我国室内空气细颗粒物防控面临的挑战,主要包括:大气污染严重,广大农村家庭以固体燃料为主,传统生活方式不易改变,公众认知程度有待提高。结合我国实情,分别从城市民宅、办公室、学校教室、医院、餐厅和农村室内角度提出了分场所的室内PM_(2.5)污染防控对策。
Current situation of indoor PM 2.5 pollution in China was investigated in terms of concentration level,chemical composition,changing rule and health hazard.It was found that both urban and rural areas in China had different degrees of indoor PM 2.5 pollution,and the mean concentration of indoor PM 2.5 in some cities reached(764±71)μg m 3,with cadmium,arsenic and benzo(a)pyrene(BaP)exceeding the standard levels seriously.The challenges to the prevention and control of indoor PM 2.5 in China were analyzed,including serious atmosphere pollution,the majority of rural areas using solid fuel,the traditional way of life not easy to change and the low level of awareness about indoor PM 2.5.Finally,combining with China s reality,the countermeasures and suggestions to solve indoor PM 2.5 pollution problem were given,respectively from the aspects of city houses,offices,classrooms,hospitals,restaurants as well as rural houses.
