| 空气污染物的类型与危害 Types and hazards of air pollutants 根据污染性质和污染来源的不同,室内空气污染物包括颗粒污染物与气态污染物两种类型,其中,颗粒污染物可以分为微生物、固体颗粒两种。颗粒污染物主要来自香烟烟雾、燃料燃烧等,很多颗粒物都对人体有着毒性,微生物污染则包括霉菌、真菌、细菌污染,这些微生物多存在于不清洁或者温暖潮湿的地方,随着空气不断流动,导致人体出现呼吸道感染、过敏等症状。 According to the different nature and sources of pollution, indoor air pollutants include two types: particulate pollutants and gaseous pollutants. Particulate pollutants can be divided into microorganisms and solid particles. Particle pollutants mainly come from cigarette smoke, fuel combustion and so on. Many particles are toxic to human body. Microbial contamination includes mold, fungi and bacteria. These microorganisms mostly exist in unclean or warm and humid places. With the continuous flow of air, respiratory tract infections and allergies occur in human body. 室内空气中的污染物包括一氧化碳、二氧化硫等气体之外,还有大量的放射性气体与挥发性有机物,室内建筑材料、家具与装修过程中使用的油漆、粘合剂以及人们日常生活中常用的化妆品、洗涤剂等,都会释放出有害气体。 Pollutants in indoor air include carbon monoxide, sulfur dioxide and other gases, as well as a large number of radioactive gases and volatile organic compounds, indoor building materials, furniture and decoration process used in paint, adhesives, cosmetics and detergents commonly used in daily life, will release harmful gases. |
