Richard C. Thompson et a. 2024. Twenty years of microplastics pollution research—what have we learned? (Review). Science, 19 Sep 2024. DOI: 10.1126/science.adl2746 https://www.science.org/doi/10.1126/science.adl2746
Abstract
Twenty years after the first publication using the term microplastics, we review current understanding, refine definitions and consider future prospects. Microplastics arise from multiple sources including tires, textiles, cosmetics, paint and the fragmentation of larger items. They are widely distributed throughout the natural environment with evidence of harm at multiple levels of biological organization. They are pervasive in food and drink and have been detected throughout the human body, with emerging evidence of negative effects. Environmental contamination could double by 2040 and widescale harm has been predicted. Public concern is increasing and diverse measures to address microplastics pollution are being considered in international negotiations. Clear evidence on the efficacy of potential solutions is now needed to address the issue and to minimize the risks of unintended consequences.

A new study in 113 men demonstrated every one had microplastics in their semen and urine samples, one of which PTFE (think Teflon), was associated with a markedly reduced sperm quality by count, concentration and motility (with dose-response).

So sad. Every inshore plankton sample I collect contains microplastic pollution. Yesterday's sample was no exception. The body of this dinoflagellate is ~ 50 µm diameter (0.05 mm). The plastic microfibre is ~ 10 µm diameter. (A human hair is ~ 70 µm.) The shocking scale of it. @Zeiss_micro

These groovy sea dancers are flashing us a warning: our oceans are turning into a plastic soup! 🥣 Let's ghost the plastic before it ghosts our marine buddies.
