I'm kind of stunned that we're just now getting a handle on problems with tire particulates. It's been roughly a century.
Default assumption in the West is if it's not medicine and it doesn't kill immediately it's good to go. Some time later, usually quite a lot, a tiny group of independent scientists end up being interested enough to scientifically prove that bloody obvious scaling problem is a problem. But by that time usually much money and politics is tied up in it. To that mix, then add in legislatures that even when they are independent have processes and bandwidth largely optimised for the pace of change from the age of sail and we end up with an endless stream of doh moments.
One glimmer of hope here is at least it looks like getting it sorted might take slightly less time than lead pipes.
