尘埃来源大气悬浮物包括气体和液体以及固体微粒。它们包括来自海洋和大陆的物质,还有大气中形成的微粒,如硫酸盐。固体微粒从植被差的地表分离出来而被带进大气(风蚀过程),其中包括岩石和矿物尘埃、细小的矿物聚集体、纤维矿石、纤维有机质和海盐。植被(生物量)燃烧可得到黑炭,它增加了大气的不透明性。不论是天然的还是人为的,火焰的烟流常常远达千里之外,从而增加了空气污染的危险。除来自世界干旱土地的强季节性输入之外,含有各种有 Dust sources Atmospheric suspensions include gases and liquids as well as solid particulates. They include substances from the oceans and continents, as well as particles formed in the atmosphere, such as sulfates. Solid particles are brought into the atmosphere (wind erosion) by separating them from poor vegetation, including rock and mineral dust, fine mineral aggregates, fibrous ores, fibrous organic matter, and sea salt. Black carbon is obtained from the burning of vegetation (biomass), which increases the opacity of the atmosphere. Whether natural or man-made, the flames of smoke are often as far away as thousands of miles away, increasing the risk of air pollution. In addition to strong seasonal inputs from the dry land of the world, there are various species there
