Nitrogen dioxide (  )

Quizplus · Accepted Answer

Nitrogen dioxide is a harmful air pollutant that can inflame the human respiratory tract, cause lung tissue damage, and harm plants. These health and environmental impacts have been observed in many regions across the world, including North America. Nitrogen dioxide is formed by both anthropogenic (human-caused) and natural sources, but photochemical reactions involving sunlight play a major role in its production. Urban areas with high traffic volumes and industrial activities are often hotspots of nitrogen dioxide pollution, although it can also be a concern in nonurban areas with high agricultural activity or wildfires.
