地球上任何地方都悬浮着颗粒大小及数量不等的固态或液态微粒的气溶胶粒子,它们构成一个宏大的世界,人类无疑处于其中并对其组成、来源、传播及其作用产生重大影响,由于各类工业的发展及诸种生产活动使得空气中粒子核素变得复杂,杂造成严重空气污染,破坏生态平衡和社会生产,农田被污染,大桥被锈蚀,尤其是气溶胶具有在高浓度时可以爆炸的特性,使得美国年均发生20多起事故(损失数百万美元),1988年我国哈尔滨市亚麻厂爆炸就是不注意安全生产,气溶胶浓度过高而引起的。本文重点在叙述气溶胶与人类疾病的关系。 1.肺纤维性变:主要由硅、铁、钴和钡的尘埃粒子所致,主要来源于采矿、采石、花冈石加工、金属磨光、喷砂、软木塞制造、制造陶器、配制研磨料等等过程。引起肺纤维性变(尘肺)有关的微粒主要与二氧化硅有关。如能引起肺疤痕的石棉,云母及高岭上等都与其中含硅有关。
Aerosol particles of solid or liquid particles of varying particle size and quantity are suspended anywhere on the earth and constitute an ambitious world in which humans undisputed and have a significant impact on their composition, origin, transmission and their effects, since The development of various industries and various production activities complicate airborne particle nuclides, causing serious air pollution, damaging ecological balance and social production, contaminated farmland, and the bridge being eroded. In particular, aerosols have high concentrations of Due to the explosive nature of the accident, more than 20 accidents (millions of dollars in losses) occur annually in the United States. In 1988, the flax plant in Harbin, China, was caused by the failure to pay attention to safety in production and excessive concentrations of aerosols. This article focuses on the relationship between aerosols and human diseases. 1. Pulmonary fibrosis: mainly due to the dust particles of silicon, iron, cobalt and barium, mainly from mining, quarrying, flower granite processing, metal polishing, sandblasting, cork manufacture, manufacture of pottery, preparation Abrasive and so on process. Pulmonary fibrosis (pneumoconiosis) -related particles are mainly silica-related. Asbestos, mica and kaolinite that cause lung scars are all associated with silicon.
