Here’s the matching of air pollutants with their major sources:
- Ammonia gas: Occurs in industrial emissions and volatile emissions from animal wastes.
- Volatile organic compounds (VOCs): Formed by the evaporation of petroleum-derived chemical products.
- Particulates: Primarily released by the combustion of coal, especially by power generators.
- Nitrogen oxides (NOx): Produced by combustion of fossil fuels, especially gasoline.
