Summary:
Since the beginning of the industrial age, slag, the glassy material left over when metals are refined from ore, has been considered ugly but harmless. But research conducted at Stanford University has found that some kinds of this voluminous mining waste, which closely resembles volcanic rock, contain high levels of potentially toxic elements and can release them into the environment.
