Fig. 3: Polymer-specific size distribution of sedimentary microplastics.
From: Substantial burial of terrestrial microplastics in the Three Gorges Reservoir, China
Proportion of different size microplastic groups in the four dominant polymer types, including cellulose, PE, PET, and PP (a). Polymer composition in the small-sized microplastics in different sampling years (b). The size distribution of different polymers was concluded based on the statistical results of 8581 counted microplastic particles. The black hollow circles represent the data points that make up the size distribution of microplastic particles. The black solid circles refer to the mean particle sizes and the horizontal bars indicate the ±standard deviation.
