“Proven health effects” is a really high bar. Universal, long term, planetary contamination with a synthetic organic polymer seems like exactly the kind of situation that would warrant an abundance of caution rather than requiring conclusive proof of harm. That said, perhaps the many studies I have seen showing that multiple plastics have hormone like effects on biological systems en vitro, especially when presented in fine particulate form were just wrong. Honestly could be. But I’ve seen an awful lot of them supporting the biological activity of plastics and plastic decomposites, and only a couple suggesting failures of replication. I’ll have to take a look into it again. Have you seen papers that strongly support biological neutrality in fine plastic particulates and decomposites?
