Question: Do oysters clean the water by "eating" the pollutants ? If so, after oysters die, wont that pollutant still be in the water? Or is it in a stable form

Question: Do oysters clean the water by "eating" the pollutants ? If so, after oysters die, wont that pollutant still be in the water? Or is it in a stable form and does not harm us.
- giorgioz 8y agoI think old oysters become rock-like and sediment while new oysters grow on top of them. "3. In the wild, oysters set on (or attach to) old oyster shells. When oysters grow in the wild in oyster reefs, they typically attach to old oyster shells (for the calcium carbonate — see above). Because of this they tend to grow in clusters and one on top of the other. This is also why wild oysters typically have “gnarly shapes,” says Chris, instead of the nice round shape and deep cup you associate with farmed oysters." https://www.thekitchn.com/island-creek-oysters-grower-tour-192689 https://www.thekitchn.com/island-creek-oysters-grower-tour-1...
- pwagland 8y agoGood question! My understanding is that a lot of the pollutants actually end up in the shell, so they don't magically disappear, but they are pulled out of the water, and they end up in the hard sediment on the sea floor.
- gdubs 8y agoThere was a TED talk on this idea a while back, and the answer to when can the oysters be eaten was “around 2050”. https://www.ted.com/talks/kate_orff_oysters_as_architecture/transcript https://www.ted.com/talks/kate_orff_oysters_as_architecture/...
