What are volatile organic compounds (VOCs)?

Volatile organic compounds (VOCs) are organic chemicals that have high vapor pressures at room temperature, which means they can easily evaporate into the air. These compounds are significant concerning air quality because they contribute to the formation of ground-level ozone and smog, posing health risks and environmental impacts. VOCs are commonly emitted from various sources, including paints, solvents, vehicle emissions, and industrial processes.

These compounds play a crucial role in both indoor and outdoor air pollution, as they can react with nitrogen oxides in sunlight to form ozone, a key component of smog. Understanding the sources and effects of VOCs is vital for assessing air quality and implementing strategies to reduce pollution and protect public health.
