Microplastic

Microplastics are usually invisible for the naked eye – they include all plastic particles less than 5 mm in diameter. Microplastics can be divided into two categories: they are considered being primary if they are originally manufactured to be small and secondary if they have been fragmented from larger plastic items. Primary microplastics include for example virgin resin pellets, industrial scrubbers used to blast clean surfaces and small microbeads present in some cosmetic products.

Microplastics can reach the sea, lakes and streams through sewage water and snow tipping.
