Ehdotuksen soveltamisala:This document establishes a qualitative-quantitative analytical evaluation (i.e., determination) of microplastics to able to define its: This document is applicable to the determination of microplastics (from textile sector) collected in different matrices (for example textile process wastewater, clothes washing water, textile process air emissions, textile process solid waste). The document specifies expression of results in terms of estimated surface area and mass of microplastics (MPs) per unit sample. This document allows to express uniquely the results of the quantifications of MP, regardless of the origin of the investigated sample (raw material, manufacturing process, environmental sample like wastewater from washing clothes, air, and industrial process water). This document determines textile sector samples of matrices of different physical states (solid, liquid or aeriform), for example: This document, being able to provide information such as size, shape, surface and mass (estimated), allows transferring information that is useful for ecotoxicological assessments to specialists. Alternatively, is possible to determine only the mass of each polymer present in the sample using the thermo-analytical methods reported in Annex D.
