Stack emissions

Definition

Stack emissions refer to the release of pollutants into the atmosphere from the exhaust stacks of industrial facilities, power plants, and other sources of combustion. These emissions are a major concern for air quality as they can contain a variety of harmful substances, including particulate matter, sulfur dioxide, nitrogen oxides, and volatile organic compounds, which can have detrimental effects on human health and the environment.
