人们在复杂的外界环境中生活,并受到各种因素的影响。在外界环境中,有自然的或人为的社会的因素等,其中代表性的因素之一就是各种气象现象。气象现象当然也是自然因素,而大气污染也与气象现象相同,是通过大气而与人体健康有密切的关系。也就是说,产生大气污染现象的本身就是人为的社会的因素,而大气污染能扩散到比较广大的区域,使自然的大气条件变质。正因为如此,大气污染不仅能单独地给人体带来影响,而且有时与各种气象现象的变化重合在一起,同时给人体带来复合的影响,而这种复合影响往往是更严重的问题。关于大气污染对人体的影响,目前已有许多报告。如上述,实际上当大气污染不与外界环境的其他 People live in a complex environment and are influenced by a variety of factors. In the external environment, there are natural or man-made social factors, etc. Among them, one of the representative factors is various meteorological phenomena. Of course, the phenomenon of meteorology is also a natural factor, and atmospheric pollution is also the same with the meteorological phenomenon, which is closely related to human health through the atmosphere. In other words, the phenomenon of air pollution itself is an artificial social factor, and air pollution can spread to a wider area, so that the deterioration of the natural atmospheric conditions. Because of this, air pollution not only affects the human body alone, but also sometimes coincides with the changes of various meteorological phenomena, and simultaneously brings compound effects to the human body, and the compound impact is often a more serious problem. There are many reports on the impact of air pollution on the human body. As mentioned above, in fact, when the air pollution is not the environment with the outside world
