What is a significant source of primary pollutants?

• A. Vegetation
• B. Industrial emissions
• C. Natural disasters
• D. Public awareness campaigns

Answer: (B)

Industrial emissions are a significant source of primary pollutants because they release harmful substances directly into the atmosphere as a result of various industrial processes. These emissions can include a variety of harmful pollutants such as sulfur dioxide, nitrogen oxides, volatile organic compounds, and particulate matter, all of which are produced during manufacturing, energy production, and chemical processing activities. Primary pollutants are those that are emitted directly from a source and can cause immediate harm to air quality and human health. Industrial activities are among the largest contributors to this type of pollution, primarily due to the combustion of fossil fuels and chemical reactions that occur in facilities. In contrast, vegetation typically acts as a natural source of secondary pollutants rather than primary ones, while natural disasters can release pollutants but are not continuous sources like industrial emissions. Public awareness campaigns do not produce pollutants; rather, they aim to educate and reduce pollution levels through behavioral changes. Thus, industrial emissions stand out as a key contributor to the issue of air quality degradation.
