Across
- 1. Federal agency responsible for enforcing environmental regulations in the United States
- 3. A primary air pollutant that is produced by the burning of fossil fuels, such as coal and oil, and can contribute to acid rain, respiratory problems, and other health issues
- 9. Federal law passed in 1963 that established air quality standards
- 11. Weather condition where a layer of warm air traps cooler air and pollutants near the ground, leading to poor air quality and health problems
- 15. Unwanted or excessive sound that can cause harm to human health and well-being, including hearing loss, sleep disturbances, and stress
- 17. Burning of coal to produce energy, which can release large amounts of pollutants into the air, including SO2, NOx, and particulate matter
- 18. A mixture of solid and liquid particles that are suspended in the air, and can be inhaled into the lungs causing respiratory and cardiovascular problems
- 19. secondary air pollutant that is formed by the reaction of NOx and volatile organic compounds in the presence of sunlight, which can contribute to smog and respiratory problems
- 20. Primary air pollutant that is produced by human activities, such as the burning of fossil fuels, and can cause damage to the nervous system, especially in children
- 21. Contributes to the greenhouse effect by absorbing and emitting radiation, and can lead to climate change including carbon dioxide, methane, and nitrous oxide
Down
- 2. Directly emitted into the atmosphere from sources such as vehicles, factories, and power plants
- 4. Formed by the reaction of sunlight with NOx and VOCs in the atmosphere, and can cause respiratory problems
- 5. Phenomenon of urban areas being significantly warmer than surrounding rural areas due to human activities, such as the use of dark-colored surfaces and buildings, and the removal of vegetation
- 6. Naturally occurring radioactive gas that can seep into buildings and pose a health risk when inhaled
- 7. Found inside buildings, such as homes and offices, and can include VOCs, radon gas, dust, and mold
- 8. Formed in the atmosphere from the reaction of primary pollutants with other substances in the air
- 10. Substances that are present in the atmosphere and can have harmful effects on human health, as well as on the environment
- 12. Primary air pollutants that are produced during high-temperature combustion, such as in vehicle engines, and can contribute to smog, acid rain, and respiratory problems
- 13. A primary air pollutant that is produced by incomplete combustion of fossil fuels, such as gasoline, and can cause headaches, nausea, and other health problems
- 14. Formed by the burning of sulfur-containing fuels, such as coal, and can contribute to acid rain
- 16. Organic chemicals that can vaporize into the air, and can contribute to the formation of smog and other air pollutants
