Insights into emerging organic pollutants extraction from polypropylene, polystyrene, and polyethylene microplastics
Summary
Researchers developed and validated an analytical method for extracting and measuring emerging organic pollutants absorbed onto microplastics, simultaneously accounting for particle size, weathering state, and environmental matrix effects for the first time. The method worked well across multiple polymer types and real environmental samples, providing a more reliable tool for assessing the chemical contamination hitchhiking on microplastics in the environment.
For the first time, the effect of particle size, weathering and matrix effect have been simultaneously evaluated on microplastics, revealing the importance of their assessment to properly validate the methodology. Additionally, the method shows good performance in all the different polymers and has been successfully applied to the analysis of environmental samples of microplastics.
