A preliminary analysis was undertaken to prepare a control technology development plan for air pollution problems facing industry. A literature search was completed (with 144 references) to estimate toxicity levels of 18 pollutants, and the magnitude of emissions from industrial emitter types or classes of emitting processes. A review of control methods organized by pollutants as well as industry, offensive trades (animal processing), food industry (brewery and cannery), chemical industry (paint and rubber), metal industry (foundry and metal coating), other (paper textile, cement, etc.) is included. Minimum controls were often reported where sites were remote to populated areas. Emission hazard data is presented in 14 tables and appendices. Flow charts indicate emission allocations in major areas of processing. Identification and emission points are shown for principal emitting processes. The survey recommends that new R and D should focus on control of non-ferrous emitters, heat and energy generating sources, open mining milling and materials handling as well as several lesser industrial sources, particularly those emitting large amounts of fine particulate material, (less than 2 micron diameter particles).
