Many substances, whether man-made or natural, can cause harm to man or the environment. Some of 
these reach the environment in waste streams; however, emission limits and environmental quality 
standards can, in some instances, reduce the amounts released. But some other substances cannot be 
controlled in this way because they are release, not in industrial waste streams, but through the use of 
disposal of products which contain them. In many cases these substances pose little or no threat if the 
product containing them is used and disposed properly. The right way to deal with them is usually 
through controls over their supply, use and disposal.
