Summary

This overview reviewed approaches to modeling microplastic input sources from coastlines into the Baltic Sea, proposing a semi-empirical formula that accounts for local anthropogenic pressure to estimate plastic particle emission rates — an important step toward predicting ocean microplastic distributions.

An overview of modern approaches to the problem of parametrisation of sources of marine waters microplastics pollution from the coastline is conducted. The estimates of Europe’s plastic production along with mismanaged plastic waste percentage that might be the source of microplastics particles input to marine environment are presented. A semi-empirical for-mulation for the particles source intensity is suggested. It considers the main factors of local anthropogenic pressure for the coastal spot location for the given coordinates. Both ad-vantages and disadvantages of such an approach along with possible ways for improvement are discussed.
