Newer concrete that has fly ash added to it does. It has a whole host of heavy metals…nickel, cadmium, mercury…all these tuff the scrubbers take out. Not too sure how much of it migrates. As to placing it in a pond one only needs to understand the base compounds for concrete usually lime/calcium and sulfate/gypsum and understand why you don't want to dump a lot in a pond. THese are natural substances but can mess with the chemical composition of the pond and its Ph. I would use it as a road bed to the entrance of our fields (no more toxic than what ever mess is along the road (rubber dust led etc) but I would not use it in a garden or in a children's play area.
