How photochemical affects the environment?

Photochemical reactions, driven by sunlight, significantly influence the environment, primarily through the formation of ground-level ozone and smog. These reactions often occur when pollutants like volatile organic compounds (VOCs) and nitrogen oxides (NOx) react under sunlight, leading to harmful air quality and respiratory issues for humans and wildlife. Additionally, photochemical processes can impact ecosystems by altering nutrient cycles and affecting plant growth. Overall, the consequences of photochemical effects contribute to climate change and environmental degradation.
