      Abstract
      Atmospheric Microplastics (AMPs) merupakan partikel plastik berukuran 1 µm hingga 5 mm yang tersuspensi di atmosfer dan telah terdeteksi hingga wilayah terpencil. Beberapa penelitian menunjukkan terukurnya mikroplastik dalam air hujan. Penelitian ini bertujuan untuk menganalisis mekanisme sirkulasi AMPs di atmosfer, termasuk karakteristik partikel, sumber emisi, proses transport, hingga interaksi dengan awan, serta mekanisme deposisi berdasarkan literatur yang dikumpulkan secara sistematis. Metode tinjauan pustaka sistematis pada penelitian ini mengikuti pedoman PRISMA, dengan 62 studi ekstraksi dari Scopus dan Google Scholar tahun 2015–2025. Hasil menunjukkan morfologi paling umum dari mikroplastik adalah fibre dengan jenis polimer dominan polyethylene terephthalate (PET) dan ukuran partikel <100 µm. Sumber emisi didominasi aktivitas urban dan mampu menempuh jarak hingga ribuan kilometer. Selama proses transport, aging mengubah permukaan partikel dari hidrofobik menjadi hidrofilik, memengaruhi proses masuknya AMPs dalam awan. AMPs terperangkap dalam droplet melalui in-cloud dan below-cloud scavenging, berpotensi sebagai cloud condensation nuclei (CCN) yang memengaruhi ukuran droplet dan albedo awan, maupun ice nucleating particles (INP) yang memicu glasiasi pada suhu lebih hangat. Deposisi basah menjadi mekanisme yang paling sering terjadi, sehingga berpotensi terdeteksinya kandungan mikroplastik dalam air hujan. Sementara resuspensi memungkinkan terjadinya pengulangan siklus. Pengendalian emisi menjadi prioritas utama untuk menekan persistensi AMPs di atmosfer.
       
      Atmospheric Microplastics (AMPs) are plastic particles ranging from 1 µm to 5 mm that remain suspended in the atmosphere and have been detected even in remote regions. Several studies have reported the presence of microplastics in rainwater. This study aims to analyze the circulation mechanisms of AMPs in the atmosphere, including particle characteristics, emission sources, transport processes, cloud interactions, and deposition mechanisms, based on systematically collected literature. A systematic literature review following the PRISMA guidelines was conducted using 62 studies from Scopus and Google Scholar published between 2015 and 2025. The results show that fibres are the most common microplastic morphology, with polyethylene terephthalate (PET) as the dominant polymer type and particle sizes generally below 100 µm. Urban activities are the primary emission sources, and AMPs can travel thousands of kilometers. During atmospheric transport, aging alters particle surfaces from hydrophobic to hydrophilic, influencing their incorporation into clouds. AMPs can be scavenged through in-cloud and below-cloud processes and may act as cloud condensation nuclei (CCN) or ice nucleating particles (INP), affecting cloud properties and glaciation. Wet deposition is the dominant removal mechanism, contributing to microplastic occurrence in rainwater, while resuspension enables repeated atmospheric cycling. Emission control remains essential to reduce AMP persistence in the atmosphere.
