Background
Micro plastics (Micro plastics) is a newly discovered organic pollutant, and has become one of the environmental problems of global importance, especially the pollution problem of atmospheric Micro plastics is a more recent focus. Research shows that synthetic fibers, mixed fibers, natural polymers (rayon, cellulose acetate and the like) and natural fibers (cotton, wool and the like) exist in the atmosphere, the pollution of the air micro-plastics (fibers) is an important source of the micro-plastics in the atmospheric environment, and the micro-plastics existing in the atmospheric environment can be settled on the land and also can be conveyed to the sea through the atmosphere, so that the micro-plastics on the earth water surface are polluted.
Atmospheric micro-plastic pollution can also directly cause harm to human health. The micro plastic in the atmosphere can be accumulated in the lung after entering the human body, so that lung diseases are caused, and meanwhile, the micro plastic can also enter other organs, and some micro plastic with small grain diameter can even directly enter blood and is transmitted to all parts of the human body through the blood. Moreover, the micro plastic can adsorb other pollutants, so that the harm caused by the micro plastic is further increased. In addition, due to their small size, microplastics are extremely susceptible to being fooled by environmental organisms and transmitted through the food chain. It can be seen that the micro-plastic is not only a source of the contaminant, but also a carrier for the contaminant. In view of this, it is necessary to further study the trend of atmospheric sedimentation micro-plastics and the harm to ecological environment.
At present, the atmospheric environmental micro-plastic pollution is mainly researched and the influence of the atmospheric environmental micro-plastic pollution on the land and sea environment is evaluated by researching the atmospheric sedimentation micro-plastic pollution and the distribution rule thereof.
