Atmospheric transport is a major pathway of microplastics to remote regions

摘要

Global annual emissions of total road microplastics (tyre wear particles, TWPs, in , and brake wear particles, BWPs, in ). TWP emissions are the average of the calculated emissions using the CO ratio method and the GAINS model. Bold numbers at the left bottom of each panel represent the annual emissions of total TWPs and BWPs from road vehicles for 2014, which were estimated to be 2907 and 174.6 kt, respectively.
