Editorial Note for Atmospheric micro plastics
AI summary Read the abstract
This editorial note introduces a journal issue on atmospheric microplastics, defining microplastics as particles ranging from 5 mm to 1 micrometer and explaining their classification into primary (intentionally produced) and secondary (formed by degradation of larger plastics) types. The piece highlights the growing recognition that microplastics are transported through the atmosphere as a major dispersal pathway.
A Microplastic is not among the type of plastics but is a plastic particle or fragment ranging from size 5mm to 100nm in size. According to the latest definition it is defined as per the standard international unit (SI) nomenclature as the plastic particle ranging from 5mm to 1micrometre. Nanoplastics are defined as the plastic fragments smaller than 1micrometre.Microplastics are generally classified into two main types i.e., primary microplastics and secondary microplastics. Primary microplastics are produced intentionally (for example production of microbeads). Secondary microplastics are the ones that are produced unintentionally. They are created by degradation and fragmentation of macroplastics that includes synthetic fibres from textile industries. Microplastics are ubiquitous and are found in diver

This review examined atmospheric micro- and nanoplastic pollution, synthesizing evidence that plastic particles are suspended, transported, and deposited globally through atmospheric pathways, concluding that air represents a major but understudied route of human exposure and environmental dispersal requiring integration into plastic pollution models.
A Review of Atmospheric Micro/Nanoplastics: Insights into Source and Fate for Modelling Studies
AI summary Read the abstract
This review synthesizes current knowledge about how micro- and nanoplastics move through the atmosphere, covering their sources, transport mechanisms, and eventual deposition. Researchers found that atmospheric transport can carry these particles over long distances quickly, making it a major pathway for global plastic pollution spread. The study identifies key knowledge gaps needed for developing accurate models of airborne microplastic behavior.
