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.
