Understanding Formaldehyde and Its Sources
What is Formaldehyde?
Formaldehyde is a colourless, strong-smelling gas commonly found in many building materials and household products. Due to its widespread use, formaldehyde is a prevalent indoor pollutant that can have serious health implications. Short-term exposure to formaldehyde can cause symptoms such as irritation of the eyes, nose, and throat, as well as coughing, wheezing, and skin rashes. Long-term exposure, even at low levels, has been linked to more severe health issues, including respiratory problems and an increased risk of cancer, particularly nasopharyngeal cancer and leukaemia.
Common Sources of Formaldehyde in Homes and Offices
Formaldehyde can be found in a variety of products and materials commonly used in both residential and commercial settings.
Building Materials
Pressed wood products like particleboard, plywood, and fiberboard are major sources of formaldehyde because they often contain adhesives made with urea-formaldehyde (UF) resins. These materials are widely used in furniture, cabinetry, and flooring. Insulation materials, particularly those made with UF foam, also release formaldehyde over time.
Furnishings and Décor
Many types of carpets, upholstery, and curtains can emit formaldehyde, especially when new. The chemical is used in fabric treatments to make them more durable and wrinkle-resistant. Additionally, some types of wallpaper and paints, particularly those labelled as “low-VOC” rather than “no-VOC,” can also release formaldehyde.
Household and Office Products
Formaldehyde is commonly found in a range of household and office products, including cleaning agents, adhesives, glues, and certain types of paper products. Even cosmetics and personal care products, such as nail polish and hair treatments, can contain formaldehyde or formaldehyde-releasing preservatives.
Factors Contributing to Formaldehyde Buildup
Several factors can contribute to the accumulation of formaldehyde in indoor environments, particularly in Singapore’s climate.
Poor Ventilation and Air Circulation
Inadequate ventilation allows formaldehyde to build up over time. Modern buildings, which are often well-sealed to improve energy efficiency, can trap pollutants indoors. Without proper ventilation, the concentration of formaldehyde and other VOCs can reach unhealthy levels.
High Indoor Temperatures and Humidity Levels
Singapore’s tropical climate, characterised by high temperatures and humidity, can exacerbate the release of formaldehyde from building materials and furnishings. Heat accelerates the off-gassing process, while humidity increases the rate at which formaldehyde is released into the air. This makes regular monitoring and mitigation efforts particularly important in this environment.
The Importance of Regular Indoor Air Quality (IAQ) Testing
Identifying and Measuring Formaldehyde Levels
Regular IAQ testing is crucial for identifying and quantifying the levels of formaldehyde and other pollutants in indoor environments. There are various types of IAQ tests available, ranging from basic air sampling kits to advanced, professional-grade monitoring systems.
Types of IAQ Tests Available
Simple, do-it-yourself test kits can provide a basic snapshot of formaldehyde levels. However, for more accurate and comprehensive results, professional IAQ assessments are recommended. These assessments often involve the use of specialised equipment that can detect and measure a wide range of VOCs, including formaldehyde, at very low concentrations.
How Formaldehyde Levels are Detected and Measured
Formaldehyde levels are typically measured in parts per million (ppm) or micrograms per cubic metre (µg/m³). Testing involves collecting air samples from different areas of a home or office over a period of time, which are then analysed in a lab to determine the concentration of formaldehyde present. Regular testing helps establish a baseline for air quality and identifies any changes over time, which can be crucial for early detection of potential problems.
Benefits of Regular IAQ Testing
Regular IAQ testing offers several important benefits that contribute to the health and well-being of occupants in homes and offices.
Early Detection of Harmful Pollutants
One of the primary benefits of regular IAQ testing is the early detection of harmful pollutants like formaldehyde.
