<p>The investigation of microplastics (MPs) in terrestrial environments has increased, including studies on atmospheric MPs in indoor and outdoor settings. However, the lack of a well-established and definitive methodology has complicated comparing the results. This article examines previous research on atmospheric MPs, providing an overview of researchers' methodologies. Additionally, it discusses the diversity and limitations of these approaches while suggesting the most effective practices identified thus far. The existing studies vary in qualitative and quantitative methods, such as sample collection, the choice of digestion and density separation techniques, MPs enumeration methods, and analytical procedures. Due to these procedural differences, the results cannot be easily compared. Establishing a standardized procedure would facilitate result comparison and enhance the reliability and credibility of atmospheric MPs studies.</p>
