Copper is death to invertebrates in the ocean. Primarily, that means 
coral, shrimp, crabs, ... While your concentrations are correct as an 
average, close to the places where the effluent water (and I mean 
processed and safe as far as sewage is considered) will have higher 
concentrations.

The stuff really should be kept out of the ocean. Of course, if you live 
near Louisiana, Mississippi, Alabama or Florida right now, it probably 
doesn't reall matter all that much.
