Volatile organic compounds

Volatile organic compounds (VOCs) are a large group of chemicals that easily become gases or vapors at room temperature. They are found in many common household products and building materials, and they can have a significant impact on indoor air quality (IAQ).

Sources of VOCs

VOCs can be emitted from a wide range of sources, including:

Paints, varnishes, and finishes: These products often contain solvents that release VOCs as they dry.
Cleaning supplies: Many cleaning products, such as air fresheners, disinfectants, and degreasers, contain VOCs.
Building materials and furnishings: Carpets, adhesives, pressed wood products, and some types of insulation can emit VOCs.
Personal care products: Hairspray, perfume, and other cosmetics may contain VOCs.
Office equipment: Printers and copiers can release VOCs.

Health Effects of VOCs

Exposure to VOCs can cause a variety of health effects, both short-term and long-term. Short-term effects can include:

Eye, nose, and throat irritation
Headaches
Dizziness
Nausea
Allergic skin reactions
Long-term exposure to certain VOCs has been linked to more serious health problems, such as:
Cancer
Liver and kidney damage
Central nervous system damage

Reducing Exposure to VOCs

There are several steps you can take to reduce your exposure to VOCs in indoor environments:

Choose low-VOC products: Look for paints, cleaning supplies, and building materials that are labeled as low-VOC or VOC-free.
Ventilate: Increase ventilation by opening windows and doors or using mechanical ventilation systems.
Use air purifiers: Air purifiers with activated carbon filters can help remove VOCs from the air.
Limit the use of products that emit VOCs: Use these products sparingly and in well-ventilated areas.

By understanding the sources of VOCs and taking steps to reduce your exposure, you can improve the IAQ in your home or building and protect your health.
