It is by no means a complete, in-depth report on all the activities of ORD, which sponsored more than 1,900 projects in 1977. What it does provide is a sampling of ORD projects, selected for review here because they represent breakthroughs in research, fill a practical technological void, are inherently interesting, or have implications for the future.environmental policyresearchenvironmental protectionBook
