Gaseous Emission Control

This section presents some options for reducing the emission of pollutants. It focuses on the complex series of processes and phenomena generally grouped under acid rain. Acid rain is associated with the release of sulphur and nitrogen oxides into atmosphere via the burning of fossil fuels. The deposition of sulfur and nitrogen compounds is one of the most pressing large-scale air pollution problems.

The options presented are based on general pollution prevention techniques. This section focuses on source control via technology changes. Source reduction measures aim at long-term reduction, while other options can limit pollution during unfavorable conditions.
