The issue of pollution caused by microplastics (MPs) is a growing concern on a global scale. Given the significant proportion of time that individuals spend indoors. The contamination in question has the potential to directly impact the human population through exposure to indoor dust and air. This study examined MPs' existence, origins, and potential health effects in indoor environments. Stereomicroscope, μRaman, and SEM-EDX were used to identify MPs in indoor environment samples. Fibers, fragments, films, lines, foam, and pellets were commonly identified as MPs with different shapes, colors, and sizes. Experiments carried out to reduce contamination during sample
preparation anad analysis. Prefiltering solutions, thermally treating filters and washing glassware found to reduce contamination. Sample preparation should be carried out in laminar flow hood. The most typical MP encountered was fibers. PTFE, PP, PA 12,
HDPE, PS, PE, LDPE, PET, PA 6, and PS were common MPs discovered in the study. These MPs included most elements: C, O, Ca, Al, Si, K, Fe, and Mg. A year later, virgin MPs indoors and outdoors exhibited physical changes indicating aging, including cracks, broken edges, ridges, grooves, and rough and uneven surfaces. It was noted that deteriorated MPs lost weight and underwent chemical characterization alterations. According to the study's findings, indoor environments are a substantial source of MPs, and further investigation is necessary to establish how they affect human health and air quality. Individuals' levels of MP exposure varied depending on their lifestyle choices, and the number of textiles and plastics found in indoor environments.
