Automotive air pollution research

Automotive air pollution research has as its objectives: (1) to understand the nature of the atmospheric effects, (2) to understand the nature of vehicle emissions, and (3) to develop concepts for the control of significant pollutants. Progress toward these objectives is reviewed with respect to photochemical smog, carbon monoxide, polynuclear aromatic hydrocarbons, lead, and diesel smoke and odour. While we have come a long way in the scientific understanding of photochemical smog and carbon monoxide pollution, and technology for the control of these problems presses hard on the heels of understanding, the need for more scientific investigations of all aspects of automotive air pollution is clear.
