A Review of Quantitative and Qualitative Methods for Microplastics in Various Media
Original title: 다양한 매체에서 미세플라스틱의 정량·정성법에 관한 고찰
Summary
This Korean review surveys quantitative and qualitative analytical methods for microplastics across environmental media, noting that primary microplastics from manufacturing and secondary microplastics from fragmentation are both widely distributed in oceans and can adsorb persistent organic pollutants. It calls for standardized methods to improve global comparability of contamination data.
Plastic accounts for 60 ~ 80% of all marine litter. Microplastics are plastic pieces that are 5 mm or less in diameter. They can be classified into primary and secondary microplastics. Primary microplastics arise from the manufacturing, and secondary microplastics arise from plastic decomposition by various factors. Both types of microplastics are not only widely distributed in the oceans, but also can adsorb persistent organic pollutants (POPs) and metals. They can be mistaken for food by marine organisms, and the resulting bioaccumulation can have a significant impact on additional ecosystems. In this study, quantitative and qualitative analysis methods for microplastics from the literature were compared and summarized.
