Most substances, either artificial 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. However,
some other matters cannot
be controlled in this way because they are released, not in industrial waste streams, but through the
use or disposal products which contain them. In many cases these substances pose
little or no threat
if the product containing them is used and disposed of properly. The accurate way to deal with them
is through controls over their supply,
use and disposal
