What are VOCs?

Volatile organic compounds (VOCs) are gaseous substances that evaporate from various materials and products. They can affect air quality and cause health problems. VOCs accumulate indoors in particular, as ventilation is often not sufficient to break them down completely.

The most common VOCs in indoor spaces

Here are some of the most common VOCs, their main sources and potential effects:

1. Formaldehyde VOC
   
   • Sources: Furniture, chipboard, paints, varnishes, adhesives, textiles
   • Risks: irritation of the respiratory tract, eye irritation, possible carcinogenic effect
2. Benzene
   
   • Sources: Tobacco smoke, paints, solvents, car exhaust fumes (also from outside)
   • Risks: headaches, dizziness, increased risk of cancer in the long term
3. Toluene
   
   • Sources: Paints, adhesives, varnishes, printing inks
   • Risks: dizziness, headaches, irritation of the respiratory tract
4. Xylene
   
   • Sources: Lacquers, paints, solvents, plastics
   • Risks: Respiratory tract irritation, headache, drowsiness
5. Acetone
   
   • Sources: Cosmetics, nail polish remover, cleaning agents
   • Risks: Eye and respiratory tract irritation, headaches
6. Styrene
   
   • Sources: Plastic products, insulation materials, carpet adhesives
   • Risks: Nervous system impairments, irritations
7. Terpenes (limonene, pinenes)
   
   • Sources: Fragrances, essential oils, cleaning agents
   • Risks: Can react with ozone and form harmful by-products
8. Trichloroethylene
   
   • Sources: Stain removers, paints, adhesives
   • Risks: Liver and kidney damage, nervous system impairment
9. Tetrachloroethylene
   
   • Sources: Dry cleaning, adhesives, paints
   • Risks: Nerve and organ damage, suspected cancer
10. Naphthalene
    • Sources: Mothballs, wood preservatives, exhaust fumes
    • Risks: Irritation of the respiratory tract, possible risk of cancer
11. ‍Ethyl acetate
    • Sources: Adhesives, nail polish remover, varnishes
    • Risks: Eye and respiratory tract irritation, headaches

12. Methanol
    • Sources: Solvents, paints, printer inks
    • Risks: damage to the nervous system, headaches, nausea

13. Chloroform‍
    • Sources: Tap water (through evaporation), disinfectant
    • Risks: Liver and kidney damage, possible carcinogenic effect

14. Cyclohexane
    • Sources: Adhesives, paints, varnishes
    • Risks: headache, respiratory irritation, drowsiness

15. 1,3-Butadiene
    • Sources: Tobacco smoke, exhaust fumes, plastic production
    • Risks: Carcinogenic potential, damage to the immune system

Formaldehyde VOC: A critical look at a widespread air pollutant

Formaldehyde VOC is a common component of the group of volatile organic compounds (VOCs) found indoors. It is a colorless, pungent smelling gas that is released from a variety of sources, including building materials, furniture, textiles and some household products.

As a VOC, formaldehyde is of particular concern as it can cause health problems, such as eye, nose and throat irritation, even at low concentrations. Long-term exposure can lead to more serious health problems, including respiratory diseases and an increased risk of cancer.

To reduce exposure to formaldehyde indoors, it is important to use low-emission products and ventilate regularly. Installing air purifiers specifically designed to remove VOCs can also help to improve air quality and protect the health of occupants.

Methanol VOC: An often overlooked indoor pollutant

Methanol VOC is a volatile organic compound (VOC) and can be found in many everyday objects and industrial applications. It is often used in cleaning agents, antifreeze and as a solvent in paints and varnishes. Due to its high volatility, methanol can easily enter indoor air and thus contribute to indoor air pollution.

The health effects of methanol exposure can range from mild symptoms such as headaches and nausea to more serious effects such as visual disturbances and neurological problems, especially with high or long-term exposure.

To reduce indoor methanol concentrations, methanol-free alternatives should be preferred and well-ventilated rooms should be created. The use of air purifiers specifically designed to remove VOCs can also help to improve air quality and minimize health risks.

How can VOC pollution be reduced?

• Ventilate regularly - Daily shock ventilation helps to reduce the concentration of VOCs.
• Choose low-pollutant products - Look for environmentally friendly and low-VOC paints, varnishes, furniture and cleaning products.
• Use air-purifying plants - Some plants, such as ivy, bowhemp or monocots, can help filter VOCs from the air.
• Control room temperature and humidity - High temperatures and humidity promote the release of VOCs.
• Store chemicals correctly - Solvents, paints and cleaning agents should be stored in well-ventilated rooms or outside the home.

The air-Q: support for VOC measurement

The air-Q is an intelligent air analyzer that helps to monitor the quality of indoor air. It measures the concentration of various pollutants, including VOCs, and provides real-time data on air pollution. By using the air-Q, you can take targeted measures to improve the air quality in your living and working spaces. It provides valuable insights into the indoor air and helps to identify and minimize pollutant sources.

Conclusion

VOCs are omnipresent in many households, but conscious measures can significantly reduce their impact. Good air quality contributes to long-term health and well-being. Look out for low-emission alternatives and ensure a regular supply of fresh air!
