Fig. 5: Dimensional analysis of microplastics (MPs) fibers and fragments.
From: Long-range atmospheric transport of microplastics across the southern hemisphere
a Fiber length; b fiber diameter; c fiber surface area; d fragment length; e fragment width; f fragment surface area. N and S indicate the latitude of the north and south, respectively. S > 70 indicates inland Antarctica. Red shaded areas indicate the Northern Hemisphere, and blue shaded areas indicate the Southern Hemisphere. The surface areas were calculated based on the particle dimensions and are not referring to the specific surface areas. Letters above violin plots correspond to statistical comparison by one-way analysis of variance (ANOVA): groups with at least one same letter indicates no statistical differences, while groups marked with different letters indicate significant differences (p < 0.05). Black lines cross the plots are median values. The source data underlying (a–f) are provided in a Source Data file.
