Fig. 2: Interannual variation of microplastics in the bed sediments of the TGR.
From: Substantial burial of terrestrial microplastics in the Three Gorges Reservoir, China
a Abundance and polymer composition of sedimentary microplastics in 2008, 2015, 2019, and 2020. b The size distribution of microplastics in different sampling years. A total of 1804, 3718, 1087, and 1972 particles were identified, examined, and carefully recorded each year (Supplementary Table 1). Boxes show the 25th and 75th percentiles, and error bars represent the 95th percentiles. Black squares and horizontal lines represent the arithmetic means and medians, respectively.
