TVOC (Total Volatile Organic Compounds) The total volatile organic compounds were analyzed using a Tenax GC or Tenax TA nonpolar column (Polarity Index less than 10) for analysis with volatile organic compounds between n-hexane and n-hexadecane .

Section 2.6.2 Volatile Organic Compounds

 

Volatile organic compounds are compounds containing one or more carbon atoms that readily volatilize at normal room temperature and pressure. These compounds exist as a colorless gas in an indoor environment. The United States Environmental Protection Agency (1989) studied and tested more than 900 volatile organic compounds in indoor environments at concentrations exceeding 1 ppbv4.

 

Volatile organic compounds can enter outdoors indoors; building materials, detergents, cosmetics, waxes, mats, furniture, laser printers, copiers, adhesives and paints used indoors emit volatile organic compounds. If these substances exceed the normal background level briefly or for a long time, the indoor air quality may be affected.

 

The report "Consensus on Indoor Air Pollutants (Recognition Based on 1984 Level)" published by the World Health Organization Working Group lists commonly found volatile organic compounds in the indoor environment (see Table 2- 1).

 

Exposure to industrial environments containing high levels of volatile organic compounds has been shown to cause central nervous system, liver, kidney and blood poisoning in the body. Individual allergies to many volatile organic compounds may cause severe reactions even at low concentrations. These reactions can occur after a single exposure to the sensitizer or multiple exposures to the sensitizer, and even after the sensitization has taken place, the sensitivities may have been elicited. Prolonged exposure to low doses of sensitizers may also cause reactions. Some studies show that the following symptoms of Sick Building Syndrome are related to exposure to volatile organic compounds commonly found in commercial buildings:

 

Eye irritation: Feeling hot, dry, blisters, watery eyes

 

Larynx discomfort: feel throat dry

 

Breathing problems: shortness of breath, bronchial asthma

 

Headache, difficulty concentrating, dizziness, tiredness, irritability

 

Prolonged exposure to chemicals containing benzene (already listed as carcinogens) can increase the chance of developing cancer. Due to the current toxicity and sensory effects on various volatile organic compounds and their mixtures, there is a lack of full understanding and, as a general rule, exposure to volatile organic compounds should be minimized.

 

3. According to the World Health Organization, volatile organic compounds are defined as compounds having a boiling point between 50-100 ° C (lower limit) and 240-260 ° C (upper limit).
