For sure, and I think that testimony was specifically with respect to microplastics in drinking water, including airborne microplastics. That is an area—both micro and nano—where the science is least definitive, so there's a lot more work to be done there.
That's why we started the work last year through the Canadian G7 presidency by pulling together chief science advisers from all G7 countries. France has taken on that work this year through the Metsä communiqué that came out recently. France will be hosting a follow-up workshop on that. You will note that the EU directive was clear that they were not in a position yet...because, on the science, there's more work to be done there.
