Formaldehyde is a colourless, pungent-smelling gas that causes watery eyes, burning sensations in the eyes and throat, nausea, and difficulty breathing
Formaldehyde is a colourless, pungent-smelling gas that can cause a range of adverse health effects. It is a volatile organic compound (VOC) that evaporates easily and is released into the air from various products commonly found indoors, such as composite wood, furniture, textiles, household cleaning products, cosmetics, and even some medicines. The primary route of exposure for humans is by breathing air containing formaldehyde, which has off-gassed from these products.
Formaldehyde is a significant indoor air pollutant, with levels typically much higher indoors than outdoors. The concentration of formaldehyde in the air and the duration of exposure influence the severity of symptoms experienced. Short-term exposure to elevated levels of formaldehyde (above 0.1 parts per million) can cause watery eyes, burning sensations in the eyes and throat, nausea, and difficulty breathing. Some individuals may also experience dizziness, while others may develop a sensitivity to formaldehyde, experiencing symptoms earlier and at lower exposure levels.
Long-term exposure to formaldehyde has been linked to more severe health issues. It is classified as a toxic air contaminant and is known to cause cancer in animals. Evidence suggests that formaldehyde can cause a rare cancer of the nasopharynx in humans, and it has been associated with other types of cancer as well. The International Agency for Research on Cancer (IARC) has recognised the carcinogenic risk posed by formaldehyde exposure.
To reduce exposure to formaldehyde, it is important to improve indoor air quality. This can be achieved by increasing ventilation, particularly when using products that may release formaldehyde, such as cleaning or cosmetic products. It is also recommended to choose low-formaldehyde products, such as formaldehyde-free insulation and paints with low-VOC certifications. Additionally, airing out new furniture and pressed-wood products before bringing them indoors can help reduce exposure, as these products tend to release the highest concentrations of formaldehyde when they are new.
While formaldehyde is a natural byproduct of certain processes, such as forest fires, it is also released into the environment through human activities. Industrial emissions, incineration, and fuel combustion from sources like unvented stoves and heaters contribute to formaldehyde pollution. With its presence in various consumer products and potential health risks, it is essential to take precautions to minimise exposure and maintain healthy indoor air quality.

Sources of formaldehyde include building materials, household products, smoking, automobile exhaust, and unvented fuel-burning appliances
Formaldehyde is a colorless, pungent-smelling gas at room temperature. It is a byproduct of combustion and certain other natural processes and is also produced through metabolic processes in the human body. It is a known human irritant and toxic substance, causing adverse health effects such as watery eyes, burning sensations in the eyes and throat, nausea, dizziness, and difficulty in breathing. Formaldehyde exposure has also been linked to an increased risk of cancer in humans.
Sources of formaldehyde are varied and include building materials, household products, smoking, automobile exhaust, and unvented fuel-burning appliances. Building materials, such as plywood, particleboard, and paneling, often contain formaldehyde. These materials are used in the construction of homes and furniture, and when used indoors, can emit formaldehyde into the air. Particleboard, for example, is used in cabinetry and furniture, while plywood is used for decorative wall coverings and cabinets.
Formaldehyde is also found in many household products. It is used in adhesives, bonding agents, and solvents, resulting in its presence in glues, paints, coatings, lacquers, paper products, and even some cosmetics and personal care products like dishwashing liquids and fabric softeners. It is added to clothing and draperies to make them wrinkle-resistant and is also used as a preservative.
Smoking, both tobacco, and cigarette smoking, is another source of formaldehyde. The combustion of tobacco or cigarettes releases formaldehyde, and when smoked indoors, it contributes to the indoor concentration of this toxic substance. Automobile exhaust is a common source of formaldehyde in the environment, as it is a byproduct of burning gasoline, among other fuels.
Lastly, unvented fuel-burning appliances, such as gas stoves or kerosene space heaters, can emit formaldehyde. Proper ventilation is crucial in reducing formaldehyde levels, and when using combustion sources, it is essential to ensure they are adequately maintained and vented outdoors.

Formaldehyde is used in the production of wood, paper, plywood, glues, adhesives, paints, coatings, textiles, and cosmetics
Formaldehyde is a colourless, pungent-smelling gas used in a wide range of industries and products. It is one of the most widely produced chemicals in the world. It is used in the production of wood, paper, plywood, glues, adhesives, paints, coatings, textiles, and cosmetics.
Formaldehyde is used in the production of wood, particularly plywood, as an adhesive. Urea-formaldehyde is used as a glue for plywood, particleboard, wood panels, and bending laminations. It is water-resistant and affordable, with excellent adhesion properties. However, it can deteriorate under warm and humid conditions and may release formaldehyde when exposed to water at high temperatures, which weakens the glue bond. Manufacturers often apply a phenolic coating to plywood to help lower formaldehyde emissions.
Formaldehyde is also used in the production of paper and pulp. It is used in the manufacture of resins, which are used as adhesives and binders in the paper industry. Formaldehyde-based glues have been used in the assembly of plywood for over 30 years, although the introduction of glues that release less formaldehyde has led to lower emissions in recent years.
Formaldehyde is used in adhesives and glues, such as urea-formaldehyde, which is used in the construction of boats and aircraft. It is strong, gap-filling, and load-bearing. However, uncured resin is poisonous and can cause eye, nose, and throat irritation, as well as skin rashes and respiratory issues at higher levels of exposure.
Formaldehyde is used in paints and coatings, often as a preservative. It is also used in textiles and clothing, where it can enhance wrinkle resistance and add permanent-press qualities. However, exposure to formaldehyde through dermal contact or inhalation can cause allergic contact dermatitis and other adverse health effects.
Formaldehyde is also used in cosmetics and personal care products, such as shampoos and liquid baby soaps. It is used as a preservative to prevent microbes from growing in water-based products. However, formaldehyde can be absorbed through the skin and has been linked to cancer and allergic skin reactions.

To reduce exposure to formaldehyde, increase ventilation
Formaldehyde is a colourless, flammable gas with a strong odour that can be detected at very low concentrations. It is a volatile organic compound (VOC) that causes cancer and other harmful health effects. It is a common pollutant found in indoor environments, with sources including furniture, wooden products, household cleaning products, cosmetics, and building materials. To reduce exposure to formaldehyde, increasing ventilation is crucial. Here are some ways to effectively increase ventilation and minimise formaldehyde exposure:
Open Windows and Doors
One of the simplest ways to increase ventilation is to open windows and doors. By doing so, you allow fresh air to enter the home and dilute the concentration of formaldehyde. Keep windows open near furniture or pressed-wood products that may emit formaldehyde. If possible, leave these items in a highly ventilated area, such as a garage, for an extended period to allow them to air out before bringing them indoors.
Use of Fans and Ventilators
In addition to natural ventilation through open windows and doors, mechanical ventilation can further enhance air circulation. Utilise fans, exhaust fans, or ventilators to promote the movement of fresh air throughout the home. This is especially important when using products that may release formaldehyde, such as cleaners, paints, or cosmetic items like nail polish remover.
Central Ventilation Systems
For more comprehensive ventilation, consider a central ventilation system such as a furnace air exchanger. These systems can efficiently bring in fresh air and remove stale air from the entire home. This is particularly beneficial for larger homes or spaces with multiple rooms.
Ventilation in Vehicles
Formaldehyde exposure is not limited to homes; it is also prevalent in vehicles. To reduce formaldehyde exposure in cars, roll down the windows, especially on hot days, to allow the vehicle to air out. Setting the car's air conditioner to circulate outside air can also help ventilate the vehicle's interior.
Avoid Smoking Indoors
Smoking indoors significantly contributes to formaldehyde exposure. By refraining from smoking or allowing smoking indoors, you can reduce the presence of formaldehyde and other harmful chemicals associated with secondhand smoke.
By implementing these ventilation strategies, you can effectively reduce your exposure to formaldehyde and mitigate its potential health risks. It is important to remain vigilant about sources of formaldehyde and take proactive steps to improve ventilation in indoor spaces.
