Before the Clean Air Act, what was a primary concern of boiler operations?

1. Carbon monoxide emissions

2. Nitrogen oxides

3. Sulfur dioxide

4. Particulate matter

The correct answer is: Sulfur dioxide

Prior to the Clean Air Act, a significant concern regarding boiler operations was sulfur dioxide emissions. This compound is produced when fossil fuels containing sulfur, such as coal and oil, are burned. The emission of sulfur dioxide can lead to serious environmental issues, including acid rain, which adversely affects ecosystems, water quality, and structures. In the context of the Clean Air Act, regulations have been designed to limit emissions of sulfur dioxide, making it a critical focus for boiler operation management. During that time, the public and regulatory attention was heavily directed at these emissions due to the harmful effects they have not only on the environment but also on human health, particularly with respiratory issues. Thus, sulfur dioxide was a primary concern before the establishment of more stringent environmental regulations under the Clean Air Act.
