Recalculating national occurrence of microplastics in China’s freshwater
Published 2025-01-01“…Summary: Microplastics are ubiquitous in freshwater; however, non-harmonization of field observations for microplastics impedes their comparability, leading to an unclear national status. Here, we developed a “size-abundance” correction method based on field observation, which could align microplastic abundances into the same size range and be well validated. …”
