Overview

Secondary analysis reveals high prevalence of elongated microplastic fibers in aquatic surface waters, highlighting potential biological risks for liver disease pathogenesis.

Key Points

To quantify the morphological distribution of aquatic microplastics and assess their potential biological relevance to liver disease pathogenesis.
Secondary analysis of 19,874 microplastics collected from surface waters between 2015 and 2020.
Evaluated particle morphology, size, color, spatial autocorrelation, and size-geometry relationships using R (v4.3.1).
Fragments (49.8%) and fibers (40.3%) dominated the sample, with fibers showing extreme aspect ratios exceeding 50:1.
Fiber abundance increased significantly between 2015 and 2018 (p = 0.012).
Significant spatial clustering was detected in the Central Bay region (p < 0.001).
