WebVOCs are chemical compounds – mixtures of more than one element – where one of the elements is carbon. They are described as volatile because they evaporate easily, releasing molecules into the atmosphere. In some places, notably California (and previously in the USA as a whole), VOCs are known as ROGs or reactive organic gases.
