Which among the following CAN NOT be categorized as VOCs?

The correct answer is Polycyclic Aromatic Hydrocarbons.

Key Points

• Polycyclic aromatic hydrocarbons (PAHs) are organic compounds with multiple aromatic rings.
• PAHs are common atmospheric pollutants that have been linked to cancer, teratogenicity, and genotoxicity.
• PAHs are produced by incomplete combustion or pyrolysis of carbon and hydrogen-containing materials such as coal, oil, wood, and petroleum products.
• Volatile organic compounds have a high vapour pressure but a low water solubility.
• Many VOCs are man-made chemicals used in the production of paints, pharmaceuticals, and refrigerants.
• Some PAHs are semi-volatile but most of them stick to the solid particles and get deposited on organic particulate matter.

Therefore, the correct answer is Polycyclic Aromatic Hydrocarbons.
