Fig. 3: Changes in the vertical component of the updraft wind speed which can carry microplastics with different lengths and densities.

L is the length of a particle and 2r is its diameter or width; and L is defined to be always larger than 2r. The smaller of the L/2r ratio is, the shape of the particle is closer to a fragment; whereas the larger of the L/2r ratio is, the shape of the particle is closer to a fiber. ρp indicates the density of a plastic particle. The source data underlying Fig. 3 are provided in a Source Data file.
