What side effects does formaldehyde have?
When formaldehyde is present in the air at levels exceeding 0.1 ppm, some individuals may experience adverse effects such as watery eyes; burning sensations in the eyes, nose, and throat; coughing; wheezing; nausea; and skin irritation.
Long term exposure to formaldehyde has been shown to be associated with an increased risk of cancer of the nose and accessory sinuses, nasopharyngeal and oropharyngeal cancer, and lung cancer in humans.
The best data I've seen suggests formaldehyde takes about two years to off-gas back to normal levels.
- Formic aldehyde.
- Methyl aldehyde.
- Methylene glycol.
- Methylene oxide.
A study by researchers at the UC Berkeley School of Public Health finds a link between exposure to formaldehyde and an increased risk of developing brain diseases such as brain cancer, Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis.
It's also naturally occurring in many foods. Fruits like apples, bananas, grapes, and plums; vegetables like onions, carrots, and spinach; and even meats like seafood, beef, and poultry contain formaldehyde.
There are tests that can detect formaldehyde in your blood, urine, and breath. These tests will not tell you how much formaldehyde is in your body, and these tests will not tell you if you will get sick or if you have formaldehyde in your body that was not produced by your body.
Formaldehyde can cause nervous system damage by its known ability to react with and form cross linking with proteins, DNA and unsaturated fatty acids (Thrasher et al., 1990).
There is no antidote for formaldehyde. Treatment consists of supportive measures including decontamination (flushing of skin and eyes with water, gastric lavage, and administration of activated charcoal), administration of supplemental oxygen, intravenous sodium bicarbonate and/or isotonic fluid, and hemodialysis.
Exposure to formaldehyde may cause health effects in some individuals. The severity of symptoms depends upon the concentration (how much) and duration (how long) of formaldehyde exposure. Additionally, some people are more sensitive to chemicals such as formaldehyde and may experience symptoms earlier than others.
What neutralizes formaldehyde?
Formaldehyde polymerization by use of urea is a proven method of neutralizing formaldehyde. The reaction of formaldehyde with urea and acid will neutralize the formaldehyde.

Formaldehyde, a major component in embalming fluid, is legal to purchase and possess and has become popular due to its euphoric properties. In significant doses, the chemical is a neurotoxin.
After adjusting for age, sex, education and other factors, researchers found people who were exposed to formaldehyde on the job had, on average, a 17% higher risk of having thinking and memory problems compared to those who were not exposed. This was true in every type of cognitive function the researchers tested.
How does formaldehyde enter and leave the body? Formaldehyde primarily enters the body through breathing, but can also enter through the skin or through ingestion. Once absorbed, formaldehyde is very quickly broken down to a non-toxic chemical and is excreted in the urine.
Upon exposure to formaldehyde via any route, it is majorly metabolized by the liver. However, this metabolism impacts negatively on the liver, and in certain concentrations can result in liver damage referred to as hepatotoxicity.
The highest incidence occurred in tequila (83%), Asian spirits (59%), grape marc (54%), and brandy (50%).
Quantitative analysis of formaldehyde in commercial brewed and instant coffees showed 3.4-4.5 ppm in the brewed and 10-16.3 ppm in the instant coffee.
Some paper products, such as grocery bags and paper towels, give off small amounts of formaldehyde. Because these products contain formaldehyde, you may also be exposed on the skin by touching or coming in direct contact with them. You may also be exposed to small amounts of formaldehyde in the food you eat.
Symptoms include itchy and burning eyes, dermatitis, headache, wheezing, and fatigue. If you're found positive for a formaldehyde allergy, you can begin to take steps to avoid exposure to the substance. This may include avoiding certain fabrics, scents, and household cleaners.
Can formaldehyde cause anxiety?
Different concentrations of gaseous formaldehyde result in different effects on anxiety, depression-like behavior and cognition ability which may be associated with alterations in hippocampal glucocorticoid receptors and brain tyrosine hydroxylase levels.
Toxins like formaldehyde and PCBs (polychlorinated biphenyls) outgas from carpet, furniture, and mattresses. Molds, dust, pet dander, pollen, perfume, air fresheners, cigarette smoke, and household cleaners get trapped inside the average home. And this chemical stew can cause brain fog, fatigue, and memory loss.
Formaldehyde (FA) is an environmental pollutant widely used in industry. Exposure to FA causes irritation of the respiratory mucosa and is associated with inflammation and oxidative stress in the airways.
It is concluded that formaldehyde is capable of penetrating through the blood-brain barrier, with the degree of permeability depending on blood formaldehyde concentration.
Drinking water is one of the best and fastest ways to flush out toxins from your system. Water transports toxins through your system via your bloodstream, making sure they're expelled from your body. Try to get the recommended 8 glasses of water per day (tip: herbal tea counts towards your water intake, too!).
