Volatile organic compounds (VOCs) are the most prevalent of indoor air pollutants, and their levels may be ten to thousands of times higher in indoor environments than found in the outdoor air. They also are the most studied of all indoor pollutants. Results of various studies have found that there may be anywhere from 50 up to hundreds of individual VOCs in the indoor air. The majority of VOCs are found to emit from indoor materials and processes. Some may produce odors at very low levels that some building occupants may consider objectionable. Many VOCs are irritants and can cause headaches and eye, nose and throat irritation, and dizziness. At high concentrations, some VOCs are toxic. Formaldehyde and toluene are the most prevalent of all VOCs.
