What is the environmental consequence of increased oxides of nitrogen in the atmosphere?

The formation of acid rain is a significant environmental consequence of increased oxides of nitrogen in the atmosphere. When nitrogen oxides are released, usually from vehicle emissions and industrial processes, they can react with water, oxygen, and other chemicals in the atmosphere to produce nitric acid. This acid then falls to the ground in precipitation, leading to acid rain.

Acid rain can have harmful effects on ecosystems, including damaging soil, freshwater sources, and plant life. It can also negatively impact buildings and infrastructure, leading to increased maintenance costs. The relationship between nitrogen oxides and acid rain is a crucial aspect of understanding air pollution and its broader environmental effects.
