【摘要】：正空气中悬浮的颗粒污染物会对人体健康产生重要影响[1]。粒径大于50μm的颗粒物受重力作用会沉降到地面,小于10μm的颗粒物(PM10)可随着呼吸进入人体肺部。PM10引起的流行病研究表明,多种有机化合物如苯、二VA英、多环芳烃以及一些含有高毒性成分的金属如铅、镉会附着在颗粒物表面而进入人体,容易引起呼吸道感染、心脏病、支气管炎、哮喘、肺炎、肺气肿等多种疾病[2-4]。细小颗粒物对人体
[Abstract]:The particulate pollutants suspended in the positive air will have an important effect on human health. Particles of [1]. particle size greater than 50 u m will settle down to the ground by gravity, and particles less than 10 mu m (PM10) can follow the epidemiological study of.PM10 caused by breathing into the lung of the human body, and a variety of organic compounds such as benzene, two VA, polycyclic aromatic hydrocarbons and some other compounds have been found. Metal such as lead, which contains high toxic ingredients, can attach to the surface of particles and enter the body. It is easy to cause respiratory infection, heart disease, bronchitis, asthma, pneumonia, emphysema and other [2-4]. fine particles to the human body
