According to a new environmental research paper published in the international academic journal Nature-Communications under Springer Nature, microplastic pollution from road traffic spreads with the wind and can be transported to distant regions, including the Arctic
.
The study, which modelled the atmospheric spread of microplastic pollution from road traffic around the world, estimates that the total amount of microplastics transported by air to the oceans is comparable to the amount that accumulates in rivers
.
The latest research paper points out that as the production rate of new plastic products continues to increase, plastic waste that has not been collected and recycled is increasing
.
To this end, the paper's corresponding author, Nikolaos Evangeliou of the Norwegian Air Research Institute, and colleagues, combined the global quantitative analysis of road plastic particles (generated by tire and brake wear) with atmospheric transport pathways.
Modeling is combined to determine the propagation trajectories of these pollutants
.
The authors of the study found that larger particles were deposited near the pollution source, and conversely, microplastics with a diameter of 2.
5 microns or less were transported further afield
