When we burn coal, various pollutants are released into the atmosphere. The primary pollutants generally include carbon monoxide, sulfur dioxide, soot, and carbon dioxide. Each of these has significant environmental and health impacts.
However, ozone is not a direct pollutant resulting from the burning of coal. Instead, it is considered a secondary pollutant, formed when primary pollutants, such as volatile organic compounds (VOCs) and nitrogen oxides, react in the presence of sunlight.
To summarize, the correct answer to the question is:
- e. ozone – is not a primary pollutant from burning coal.
