It is not a typical Hollywood film effect but microplastics falling from the sky are real-and should be taken seriously.Recent studies have shown that microplastics are no longer concentrated only in the oceans.Mismanaged wastes that are either I a n df i I led or entering the oceans break down into tiny pieces,and are circulated in the atmosphere.One recent study by researchers at Cornell and Utah State Universities says that microplastics from the oceans,roads and agricultural soils are purged into the atmosphere via mechanical processes.The airborne 2.5 micron or less in size microplastic wafts from urban areas to remote areas.The study,published in the Proceedings of the National Academy of Sciences(PNAS),found this plastic cycle to be similar to the biogeochemical cycles of water or nitrogen.
