Volatile Organic Compounds (VOCs) as Environmental Pollutants

Dec 13, 2021 · Volatile organic compounds (VOCs) are organic chemical compounds found in various products that easily vaporise and reach in the environment under normal conditions. VOCs have increased volatility, mobility and they are resistant to degradation, being able to be transported to long distances in the environment [ 1 ].
