有人认为雾是一种较为清洁的降水形式,对人无危害.是这样吗?其实雾是由凝结核和水组成,凝结核主要由粉尘微粒、硫化物、齿化物和有机化合物等组成.雾中含有大量的大气污染物,大气中的二氧化硫(SO_2)、三氧化硫(SO_3)、硫化氢(H_2S)、氯化氢(HCl)等气体与水结合形成酸雾.科学家发现,在同一地区的酸性降水中,酸雾比酸雨的酸度高出几十倍乃至上百倍,所以这种酸雾比称之为“空中死神”的酸雨更可怕.
Some people think that the fog is a relatively clean form of precipitation, and harmless to human beings. Is it true? In fact, the fog consists of condensed nuclei and water, and the condensed nuclei consist mainly of dust particles, sulfides, selves, and organic compounds. Contains a large amount of air pollutants, the atmosphere of sulfur dioxide (SO2), sulfur trioxide (SO3), hydrogen sulfide (H2S), hydrogen chloride (HCl) and other gases combined with water to form acid mist.Scientists found that in the same area of the acid Precipitation, acid mist than the acidity of acidity higher than a few times or even hundreds of times, so this acid fog than called “sky death” acid rain even more terrible.
