Micro Raman analysis of micro and nanoplastics in drinking water: from number to mass

Works focusing on micro- and nanoplastics analysis in drinking water by means of Raman microscopy have been raising in recent years, however a standardised protocol is still lacking. Moreover, at the best of our knowledge, no paper among them proposed a reliable way to calculating the particles masses. The current research aims to fill this gap by presenting a new analytical method employing Raman microscopy, applied to drinking water samples from a Danish facility. This work supports the above mentioned view and offers a comprehensive application of such principles, with the authors stressing the pivotal role of method validation when dealing with micro- and nanoplastics analysis.
