Which one is more harmful, formaldehyde or toluene

Formaldehyde and toluene are relatively common chemical components, and they are also toxic gases. If you smell these gases for a long time, it will cause great harm to human health. Whether it is formaldehyde or toluene, it is best not to stay in such an environment for a long time, otherwise it will easily damage your body. Formaldehyde and toluene are both toxic gases, and the harm is very great. In severe cases, it may endanger your life.

Which one is more harmful, formaldehyde or toluene?

From a social perspective, formaldehyde is very harmful. Formaldehyde ranks second on my country's toxic chemicals control list. At the same time, it is also identified as a Class 1 carcinogen by the World Health Organization.

For individuals, it depends on the contact time. Benzene can be dissipated in about 7-9 days, while formaldehyde needs 3-15 years to stop volatilizing. If you are exposed to Bon for a short time, the amount of formaldehyde will be higher, and if you are exposed to it for a long time, the amount of formaldehyde will be higher.

Formaldehyde: Long-term exposure to low doses of formaldehyde can cause chronic respiratory diseases, menstrual disorders in women, pregnancy syndrome, reduced physical fitness in newborns, chromosomal abnormalities, and even nasopharyngeal cancer. Formaldehyde can also cause neonatal malformations and cancer.

Benzene: Frequent contact with benzene can cause the skin to become dry and flaky due to degreasing. Some people may develop allergic eczema and newlyweds may become infertile. Long-term inhalation of benzene can lead to aplastic anemia and leukemia, especially in children with weak immune systems. Can cause birth defects in the fetus.

Effects of formaldehyde on children

1. Formaldehyde has a strong irritating effect on the skin and mucous membranes. It is a protoplasmic toxic substance that can combine with protein. Inhalation of high concentrations can cause severe respiratory irritation and edema, eye irritation, and headaches.

2. Formaldehyde is sensitizing. Direct skin contact with formaldehyde can cause allergic dermatitis, pigmentation, and necrosis. Inhalation of high concentrations of formaldehyde can lead to bronchial and nasopharyngeal tumors.

Common symptoms include chest tightness, nausea, skin, rash, asthma, etc. In severe cases, formaldehyde can cause coma or even death when ingested.

3. Formaldehyde has the greatest impact on children. Excessive formaldehyde can easily induce blood diseases in children.

Medical research shows that children's immune systems are relatively fragile, and excessive levels of harmful gases such as indoor formaldehyde are the main cause of leukemia. The World Health Organization announced that 100,000 people die from asthma every year due to indoor air pollution, 35% of whom are children. According to statistics, the asthma prevalence rate among children in my country is 2-5%, among which the prevalence rate among children aged 1-5 is as high as 85%. Formaldehyde has become a major cause of asthma in children.

4. The volatilization period of formaldehyde is relatively long, generally 3 to 15 years. Therefore, if it is a new house, you must not move in immediately.

How to reduce the presence of formaldehyde indoors?

1. Using indoor building and decoration materials with low formaldehyde content or no formaldehyde is the most effective way to reduce formaldehyde pollution from the source.

2. Choose a regular decoration company and try to use interior decoration and decoration materials that meet national standards. This is the fundamental way to reduce the content of harmful gases in indoor air.

3. You should choose furniture produced by regular companies, and pay attention to choosing products with less irritating odor, because the stronger the irritating odor, the higher the amount of harmful gases released. It is best to leave newly purchased furniture vacant for a while before using it.

4. It is not advisable to move into a room immediately after decoration. Instead, you should allow a certain amount of time for the harmful gases in the materials to dissipate at a high intensity.

5. Keep the indoor air circulating and open the windows for ventilation, which will help to disperse and discharge harmful gases indoors. In humid conditions, formaldehyde easily dissolves in water in the air, and the amount absorbed by humans will increase significantly. Therefore, if the climate is humid, it is best to place a dehumidifier indoors to remove moisture.
