VOCs are various organic compounds with a boiling point between 50°C and 260°C at room temperature. VOCs participate in the formation of ozone and secondary aerosols in the atmospheric environment, significantly impacting regional atmospheric ozone pollution and PM2.5 pollution. Most VOCs have a distinctive, unpleasant odor and are toxic, irritating, teratogenic, and carcinogenic. Benzene, toluene, and formaldehyde, in particular, can cause significant harm to human health.
