What are VOCs in Air?

VOCs stand for Volatile Organic Compounds, also sometimes referred to as Reactive Organic Gases (ROGs), which are organic chemical compounds that can easily become gases or vapors. These compounds are found in both indoor and outdoor air and can be emitted by various products, including household products, building materials, and industrial emissions.

The nature of VOCs allows them to evaporate quickly into the air, contributing to air pollution that can harm human health in many ways. Whether in outdoor air or indoor environments, VOCs are present in varying concentrations, making it necessary to understand their effects on air quality.

Indoor VOCs vs. Outdoor VOCs

Indoor and outdoor air can both contain volatile organic compounds (VOCs), but they differ in sources and effects. Outdoor air pollutants typically come from industrial emissions, vehicle exhaust, contaminated soils, and natural sources like plants, while VOCs indoors often originate from household items such as paints, cleaning supplies, furniture, and building materials.

Outdoors, VOCs tend to disperse more readily due to open air and wind, often posing less concentrated exposure risks than those inside homes. Meanwhile, indoor volatile organic compounds (VOCs) can accumulate in higher concentrations, especially in poorly ventilated spaces, which may lead to more immediate health impacts like headaches, dizziness, and respiratory irritation.

What are VOCs in Air

What Makes a Compound Organic?

An organic compound is primarily composed of carbon atoms bonded with other elements like hydrogen, oxygen, and nitrogen. Organic chemicals are essential in both natural and industrial processes due to their carbon-based structures, which can form complex molecules.

When certain organic compounds have low boiling points and are chemically reactive, they can readily vaporize at room temperature, becoming volatile organic compounds (VOCs). This transition from a stable organic compound to a VOC occurs through chemical reactions or evaporation, leading to their presence in the air, where they may contribute to pollution and impact health.

Where Do VOCs Come From?

VOCs come from various sources, including a surprising number of household products. Common culprits include permanent markers, cleaning products, compressed aerosol products, craft supplies, air fresheners, pest solutions, and home improvement supplies. Products containing methylene chloride and isopropyl alcohol and chemicals like gasoline and paint strippers also let out huge amounts of VOCs. Typically, a well-sealed container is enough to keep these from affecting your indoor air quality, but be sure to keep them away from children and store them somewhere safe, such as a garage or shed.

Certain indoor furnishings, like new furniture, carpets, and drapes, may also emit VOCs over time. Gas stoves and household items like office equipment, including printers and copiers, also contribute to VOC emissions in indoor environments, especially when poorly ventilated.

Volatile Organic Compounds Examples

  • Paints and varnishes
  • Cleaning products
  • Building materials (e.g., plywood, adhesives)
  • Air fresheners and compressed aerosols
  • Gasoline and other fuels
  • Permanent markers and craft supplies
  • Fire retardants
  • Tobacco smoke
  • Pesticides and insecticides
  • Nitrogen oxides (often produced by combustion from car engines and industrial plants)
  • Gas stoves
  • Office equipment
  • Indoor furnishings

Volatile Organic Compounds Examples

How Long Do VOCs Last?

The duration VOCs remain in the air depends on their volatility. Most VOCs emitted are relatively short-lived but can linger indoors for hours or even days, especially in poorly ventilated spaces. Very volatile organic compounds (VVOCs) tend to disperse quickly, whereas semi-volatile organic compounds (SVOCs) are more persistent, attaching to surfaces and staying longer. The least volatile compounds may last months to even years, slowly releasing into the air and potentially impacting air quality over extended periods.

How VOCs Impact Indoor Air Quality

VOCs significantly impact indoor air quality, as they can accumulate in enclosed spaces, especially where ventilation is limited. Once in the air, VOCs can contribute to a range of health effects. Short-term exposure to high levels of VOCs can cause mild symptoms such as headaches and nausea, while prolonged exposure to elevated VOC levels has been linked to more serious health issues, including an increased risk of cancer.

Indoor air quality can also be affected by the concentration and type of VOCs present. Some VOCs, like formaldehyde, are particularly harmful and tend to linger longer in the air. Additionally, when VOCs interact with other indoor pollutants, they can create secondary pollutants that may further degrade air quality.

To manage VOC levels, proper ventilation, using low-VOC or VOC-free products, and regular air quality monitoring are essential steps to ensure a healthier indoor environment.

What Are the Harmful Effects of VOCs?

VOC exposure can lead to a wide range of health effects, depending on the level and duration of contact. Short-term exposure to low concentrations of VOCs may cause:

  • Headache
  • Sore throat
  • Wooziness
  • Lung irritation
  • Coughing or wheezing
  • Fatigue

High-level or long-term exposure to these volatile organic compounds can lead to more serious effects like:

  • Damage to the central nervous system, resulting in tremors, memory loss, or seizures
  • Respiratory illnesses like asthma or bronchitis
  • Increased risk of cancer
  • Health risks to vulnerable populations, such as children and the elderly

The combination of VOCs with other air pollutants, including carbon dioxide and carbon monoxide, further exacerbates health risks, leading to long-term adverse health effects. In particular, substances like ethyl benzene, often found in industrial emissions, are known for their health risks and can increase cancer risk after prolonged exposure.

Why Do VOCs Go Up at Night

Why Do VOCs Go Up at Night?

VOC concentrations tend to increase at night, primarily due to reduced ventilation and air movement in homes. When doors and windows are closed, and HVAC systems operate less frequently, the fresh air supply decreases, allowing VOCs to accumulate.

Human activity also contributes to VOC levels; everyday actions like cooking or using household products release VOCs. This build-up is more noticeable at night when airflow is more stagnant. Lower temperatures and changes in standard atmospheric pressure can also contribute to VOC emissions during nighttime hours.

How To Test for VOCs

Testing for VOCs is essential for identifying potential risks and improving indoor air quality. There are several methods to measure VOC emission rates and concentrations, from DIY air quality monitors to professional testing services. These methods help detect the presence of common VOCs and other organic pollutants in both residential and commercial spaces.

  • Air Quality Monitors: These devices measure VOC concentrations in real-time and can help you identify sources of indoor air pollution.
  • Professional Air Quality Testing: A professional HVAC service provider can conduct more thorough testing, identifying specific VOCs and recommending solutions to address air quality issues.
  • VOC Sensors: These sensors are often integrated into home air quality systems to alert homeowners when VOC levels exceed safe thresholds.
  • Measurement Methods: Using various measurement methods, such as sampling air or testing surfaces, can give more accurate readings of VOC concentrations in your indoor spaces.

How To Remove VOCs From Home

Once VOCs are present in your indoor environment, you must take steps to remove them. Methods to remove VOCs include:

  • Increase Ventilation: One of the easiest ways to remove VOCs is to improve airflow in your home. Open windows and doors to allow fresh outdoor air to circulate. You can also use exhaust fans in high-use areas like kitchens and bathrooms to reduce the accumulation of VOCs indoors.
  • Air Purifiers: Devices equipped with HEPA or activated carbon filters effectively trap VOCs and indoor air pollutants.
  • Houseplants: Some indoor plants, such as spider plants and peace lilies, are known to absorb VOCs and help clean the air. While plants can complement other air-purifying solutions, they should not be relied on as the sole method for removing VOCs.
  • Eliminate Sources: If possible, remove or reduce the use of household products that emit VOCs. Switch to non-toxic or low-VOC products whenever feasible.

How To Reduce VOCs

How To Reduce VOCs

The best way to reduce VOCs in your home is not to use items that release them into the air in the first place. Replace bleach-based cleaning supplies with natural options and research harsh chemicals before buying cleaning products. Of course, this isn’t always feasible, even though many products are now formulated to emit fewer volatile-organic compounds.

Store household chemicals, such as organic solvents, fuels, and cleaning products, in sealed containers and keep them in well-ventilated areas like garages or outdoor sheds. Avoiding aerosol products like air fresheners can also help minimize VOC emissions, but you should opt for non-aerosol alternatives whenever possible. Lastly, limit indoor smoking, as tobacco smoke is a major source of VOCs and other harmful pollutants. To prevent VOC buildup, restrict smoking to outdoor areas.

If you have to use something that’s known for releasing these chemicals, make sure your home is well-ventilated to reduce volatile organic compounds. You can use an exhaust fan or simply open the windows to let in fresh air, or get extra protection by using air purifiers.

The Importance of Regular HVAC Maintenance in Controlling VOC Levels

Regular HVAC maintenance plays a crucial role in controlling levels of volatile organic compounds (VOCs) and ensuring optimal indoor air quality. Things like routinely changing air filters and obtaining regular air duct cleaning can effectively reduce the concentration of airborne pollutants by preventing them from circulating throughout the space.

Well-maintained systems also enhance ventilation, allowing for a steady flow of fresh air that helps dilute and remove harmful compounds. Additionally, professional heating and air conditioning maintenance can identify and rectify any issues that may contribute to increased VOC levels, such as leaks or inadequate airflow.

By keeping their HVAC system in good working order, homeowners can create a healthier living environment, minimizing the risks associated with high VOC exposure.
