I don't think it would be a problem. after all I put about 10 pounds of lead into the rivers myself a year. multiply that by 1000+ fishermen and a hundred years of lead shot duck hunting. it don't bother the river
I dont know but lead is a toxic element and could kill humans as well as fish. I guess its okay if its not really lead but some other metal and its just called lead.
