Methane is primarily emitted from natural sources such as wetlands and agriculture, rather than industrial activities.

Power plants that burn fossil fuels, particularly coal, are the largest source of sulfur dioxide emissions in the United States.

Nitrogen oxides, when combined with sunlight, react to form ozone, a major component of smog.

Particulate matter, especially fine particles, can penetrate deep into the lungs and cause respiratory problems such as asthma, bronchitis, and lung cancer.

Electricity generation, particularly from fossil fuel power plants, is the largest industrial source of greenhouse gas emissions globally.

Air pollution control refers to the techniques and technologies used to reduce or eliminate air pollutants emitted from industrial processes.

Sulfur dioxide emissions from industrial sources can contribute to acid rain when they react with water vapor in the atmosphere to form sulfuric acid.

Carbon dioxide is the most significant greenhouse gas emitted by industrial activities, primarily from the burning of fossil fuels.

Steel production, particularly through the use of blast furnaces, is a significant source of nitrogen oxide emissions due to the high temperatures involved.

Carbon capture and storage involves capturing carbon dioxide from industrial emissions and storing it underground or in geological formations.

Nitrogen oxides, when combined with sunlight, react to form tropospheric ozone, a harmful air pollutant that can cause respiratory problems.

Greenhouse gas mitigation refers to the strategies and actions taken to reduce greenhouse gas emissions from various sources, including industrial activities.

Manufacturing industries, particularly those involving processes such as mining, construction, and metalworking, are major sources of particulate matter emissions.

Vehicle emissions control refers to the techniques and technologies used to reduce air pollutants emitted from vehicles, such as catalytic converters and particulate filters.
