Innovative Remedial Concepts to Address Microplastics
août 11, 2023
Microplastics (MP) encompass plastic particles ranging in size from 1 nanometer to 5 millimeters. MP historically appeared in lotions and creams as “microbeads,” which acted as exfoliants. MP also form through different processes including the gradual degradation of larger plastic items over time, which results in the generation of progressively smaller plastic particles. Additionally, textiles and synthetic clothing can form MP from daily wear and tear.
