采暖季节污染严重 冬季来临,门窗紧闭,人们在居室内停留活动时间增加,导致污染加重,这些污染物主要来自燃料燃烧、人的活动、建筑材料、室外污染物等。 矿物燃料如煤、油等和气体燃料如液化气、天燃气等,在燃烧时可产生二氧化碳、一氧化碳、氮氧化物、碳氢化合物、可吸入颗粒物等污染物。在住宅中,厨房是主要的污染源,即使我们使用电灶,如红外灶,电磁灶等也有污染,尤其是氮氧化物污染已引起人们的不安。香烟中有300多种化学物质,除一氧化碳、氮氧化物、烷烃、烯烃、芳香烃、含氧烃、氰化物、氨外,还有亚硝胺、砷、镉、钼等,其中不少具有致癌性。来自砖瓦、水泥、混凝土及各种矿渣砖等建筑材料的污染物有氡及其
In the heating season, serious pollution is coming in winter, doors and windows are closed, and people spend more time staying in their homes, resulting in more pollution. These pollutants come mainly from fuel combustion, human activities, building materials and outdoor pollutants. Fossil fuels such as coal, oil, etc. and gaseous fuels such as liquefied gas and natural gas can generate pollutants such as carbon dioxide, carbon monoxide, nitrogen oxides, hydrocarbons, respirable particulate matter and the like during combustion. In the house, the kitchen is the main source of pollution, even if we use electric stoves, such as infrared stoves, cookers and other pollution, especially nitrogen oxides pollution has caused people’s anxiety. There are more than 300 kinds of chemical substances in cigarettes, in addition to carbon monoxide, nitrogen oxides, alkanes, alkenes, aromatic hydrocarbons, oxygenated hydrocarbons, cyanide, ammonia, but also nitrosamines, arsenic, cadmium, molybdenum, Carcinogenicity. Pollutants from building materials such as tile, cement, concrete and various slag bricks are radon and its
