What is the principal source of ambient air pollutants in both developed and developing countries?

  1. Volcanic eruptions

  2. Fuel combustion

  3. Solar radiation

  4. Decomposition of organic matter

The correct answer is: Fuel combustion

Emissions from fuel combustion, such as from cars, power plants, and industrial processes, are the main source of ambient air pollutants. While volcanic eruptions can release pollutants into the air, their impact is relatively small compared to anthropogenic sources. Solar radiation does not directly contribute to air pollution, although it can lead to the formation of other pollutants such as ozone. Decomposition of organic matter, while it can produce some air pollutants, is not a major contributor to ambient air pollution in developed and developing countries.
