The united states environmental protection agency defines it chemically as: carbon compounds other than carbon monoxide, carbon dioxide, carbonic acid, metal carbides, carbonates and ammonium carbonate may participate in atmospheric photochemical reactions. VOCs are various in types, and can be further divided into eight types according to different chemical structures: alkanes, aromatic hydrocarbons, alkenes, halocarbons, esters, aldehydes, ketones, and others.
Soil pollution caused by VOCs is not easy to find by people like atmospheric and water pollution. Since soil is a complex three-phase coexistence system, various harmful substances are always combined with soil. Soil contamination is manifested primarily by the plants.
