Of course, the copper based antifouling that replaced TBT isn't exactly benign either. Though the new generation of siloxane based antifouling that work by being slippery and hard for organisms to attach rather than being poisonous seems promising.

- hinkley 3y agoWhen I last went in for brake pads I got to chatting with the manager and he said they’ve phased copper out of brake pads for environmental concerns. This EPA announcement says reduce to <5% by 2021, which to me means there wasn’t a little copper but rather it was a major ingredient. https://www.epa.gov/npdes/copper-free-brake-initiative https://www.epa.gov/npdes/copper-free-brake-initiative If the copper is bound to the hull paint well enough, maybe it’s fine? Or maybe fine in fresh water.

If it's bound up in the paint matrix it's kind of hard for it to poison those pesky critters, no? AFAIU all biocide based anti fouling paints work by being more or less ablative, continually exposing fresh biocide to the surface.
