Analysis of microplastics in detergents
AI summary Read the abstract
Researchers developed methods to detect and characterize microplastics in commercial detergent products using Raman spectroscopy, finding plastic particles intentionally added for functional purposes in some products. Microplastics deliberately added to consumer products represent a direct and preventable source of plastic pollution when products are washed down drains.
Microplastics (MPs) are found in the environment, originating from the degradation of mismanaged plastics waste but also from deliberate addition to commercial products. The latter may be added with specific functionalities, however they will remain in the environment with negative consequences, and their use should be rationalized. The present work is a contribution to the analysis of microplastics in commercial detergents. The sample preparation, filtration procedures, detection of MPs, their analysis and characterization are discussed. The identification and characterization of the MPs was carried out on a Raman spectrometer Horiba LabRAM HR Evolution microscope, equipped with the software Particle Finder.
