Fig. 2: Microplastic particle properties in forest throughfall deposition and forest soil.
From: Forest soils accumulate microplastics through atmospheric deposition
a Cumulative MP polymer composition (percentage%) at all sampling sites in throughfall deposition and forest soil. b Microplastic particle size (µm) in both sample types with Wilcoxon test p-value. c Microplastic particle aspect ratio (longest to shortest dimension of each particle) in both sample types with Wilcoxon test p-value. Sample size in throughfall deposition samples (n) = 152 particles and in forest soil samples (n) = 513 particles.
