Microfiber cloths are, on the other hand, a major source of microplastic pollution. They are basically just ready-to-snap-off microplastic particles. They shed a substantial % each washing cycle. Something like 80 % of all microplastic pollution sampled in ocean water is from microfibers.

I'm confident that microfiber cloths are responsible for 0% (rounded to the nearest whole percentage) of oceanic microplastics. But it's possible that all clothing and fabrics combined are responsible for a significant fraction of microplastic pollution. If this is the case, then the government should do its duty in regulating externalities and mandate exhaust filters in washing machines.

Do you have a source on that? I'd like to understand the definition of "micofibre" in this context to see of I need to change my purchasing habits.

  IDK about the claim, but here is a good dive into what it is and how it works. https://backreaction.blogspot.com/2013/05/what-is-microfiber-cloth-and-how-does.html https://backreaction.blogspot.com/2013/05/what-is-microfiber...

  Microfibre materials (fabrics, etc) are by definition microplastics. They shed like crazy, too.

  The 85 % figure is from Environ. Sci. Technol. 2011, 45, 21, 9175–9179 https://pubs.acs.org/doi/abs/10.1021/es201811s https://pubs.acs.org/doi/abs/10.1021/es201811s The 200-500 kiloton/year is from https://pubs.acs.org/doi/10.1021/acs.est.3c05955 https://pubs.acs.org/doi/10.1021/acs.est.3c05955 For a deeper dive you can peruse the works that cite these articles, there's lots of research into microplastic population dynamics. Unfortunately most reach similar conclusions.

Not is derived. And not microfiber solely.
