  Environmental samples from air, soil and water

  Volatile organic compounds (VOCs) are organic compounds which volatilize at lower temperatures e.g. limonene, ethanol and formaldehyde. Semi-volatile organic compounds (SVOCs) are organic compounds which tend to be solid or liquid at lower temperatures e.g. pesticides, polycyclic aromatic hydrocarbons (PAHs) and polychlorinated
