Is any of that known to leech out to sea water in amounts dangerous to anything, or at least significant relative to natural trace content?
(Pretty sure it doesn't)
- woodruffw 4y agoProbably not asbestos, but lead and other heavy-metal leaching would probably depend on local water conditions.
- jojobas 4y agoWhere would these be used in an average ship, or any ship in particular? Lead is naturally found in sea water within 2-30 ppb. To raise global lead concentration by 1 ppb you need to dump a few billion tons of lead. It's often said that solution to pollution is dilution.
- dan-robertson 4y agoAnti-fouling paint used to have a lot of lead in. I think it might be other heavy metals now. I’m not sure how quickly things diffuse deep in the ocean, but I would guess quite slowly.
- ClumsyPilot 4y agoWe have dunped so much mercury into the ocean, that you can get poisoning if you eat tuna too often
- jojobas 4y agoWrong, it's about the food chain concentrating mostly natural mercury in long-lived predator species. >Mercury is an element the emissions of which from its natural sources exceed its anthropogenic emissions. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5013138/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5013138/
