- Retric 4y agoI have seen wildly different estimates for the origins of micro plastics from different studies. The obvious issues are plastics breakdown at wildly different rates so the ratios of plastic pollution doesn’t match the ratios seen in the ocean. There are significant differences in where each type of plastic enters the ocean and where it ends up so sampling different parts of the ocean results in different observations. Finally sizes vary widely so measuring by volume, piece, or weight gives different results. On top of this it’s not always easy to say the actual origin of a given piece was.
