What are primary sources of air pollution?

• A. Household waste and sewage
• B. Industrial processes and vehicles
• C. Solar energy production
• D. Recycling efforts

Answer: (B)

Primary sources of air pollution include industrial processes and vehicles because they directly emit pollutants into the atmosphere. Industrial activities often release a variety of harmful substances, including particulate matter, volatile organic compounds, and greenhouse gases, as a byproduct of manufacturing and production processes. Additionally, vehicles, including cars, trucks, and buses, burn fossil fuels, producing emissions such as carbon monoxide, nitrogen oxides, and particulate matter, which contribute significantly to urban air pollution. Household waste and sewage do not typically lead to direct emissions into the atmosphere in the same way that industrial processes and vehicles do, as their primary impact is more related to ground and water pollution unless they contribute to issues like methane emissions from decomposition. Solar energy production, while a renewable energy source with low emissions, does not contribute to air pollution as a primary source. Recycling efforts, on the other hand, are aimed at reducing waste and can minimize environmental impact, rather than being a direct source of pollution.
