Summary

Researchers evaluated the effectiveness of hydrogen peroxide treatment at three concentrations for cleaning filters bearing dark brown tissue residues from biota microplastic analysis, testing whether H2O2 can reduce organic material sufficiently to allow accurate identification and quantification of embedded microplastic particles.

Residues of organic material after chemical digestion are a common issue in the filters used for microplastic evaluation in biota. Microplastics embedded within this organic material pose significant challenges for accurately identifying and quantifying them. This study aimed to evaluate the effectiveness of hydrogen peroxide in reducing the organic material from filters already used to analyze microplastics in tissues. We selected filters with homogeneous dark brown color tissue residue content. These filters were subjected to bifiltered distilled water and three concentrations of hydrogen peroxide (6 Also see: https://micro2024.sciencesconf.org/559717/document
