Occupational and Environmental Health: Recognizing and Preventing Disease and Injury - Multiple Choice Questions - Learn & Prevent

In addition to motor vehicle traffic, what contributes significantly to ambient air pollution in cities of developing countries?

1. Satellite launches

2. Industrial wastewater

3. Residential cooking and heating with solid fuels

4. Excessive use of aerosol products

The correct answer is: Residential cooking and heating with solid fuels

Residential cooking and heating with solid fuels contribute significantly to ambient air pollution in cities of developing countries. This is because in many developing countries, households rely on traditional cooking methods and fuels such as wood, coal, and biomass, which produce large amounts of smoke and harmful pollutants. This is due to a lack of access to clean and efficient energy sources. Option A, satellite launches, do not contribute significantly to ambient air pollution in cities as they occur far less frequently compared to motor vehicle traffic. Option B, industrial wastewater, is a factor in water pollution, not air pollution. Option D, excessive use of aerosol products, may contribute to local air pollution but is not a significant factor in ambient air pollution in cities of developing countries. Therefore, option C is the correct answer.
