Volatile Organic Compounds (VOCs) are a class of chemical compounds that readily evaporate into the air at room temperature. They encompass a variety of compounds including hydrocarbons, aldehydes, ketones, halogenated compounds, and others. VOCs can originate from natural sources like plant emissions or anthropogenic sources such as fuel combustion, industrial emissions, agricultural activities, and solvent use. Some VOCs, like benzene, formaldehyde, and toluene, are toxic, causing irritations, headaches, and long-term risks such as respiratory issues and cancers. They contribute to air pollution, forming tropospheric ozone and fine particles associated with urban smog. Strict regulations limit industrial emissions and promote low-VOC products. Efforts are made to encourage environmentally friendly alternatives. Monitoring VOCs, crucial to assess their impact, utilizes devices in urban areas, industrial facilities, and other high-risk zones, employing emission control technologies.
