Notes

Important anthropogenic inputs of copper into the ocean include urban sewage sludge dumping, runoff from copper mines, antifowling paints[2], Copper is an essential element for animals, especially decapods, gastropods and cephalopods need copper in the respiratory pigment hemocyanin. Hemocyanin is a protein which (like hemoglobin) binds oxygen to transport it to the tissues. It is however also one of the most toxic metals to a wide spectrum of marine life.
