Formaldehyde pollution, what should I do with you?

In the cold winter, smog is frequent, and more and more people choose to stay indoors. But have you ever thought that indoor air pollution may be more terrible than the smog outside the window?

The harmful substances such as formaldehyde, benzene and ammonia in the familiar indoor decoration exceed the standard, which is an important cause of indoor air pollution and seriously threatens human health. Among them, formaldehyde ranks first among several major indoor air pollution.

Then let's talk about the king of indoor pollution-formaldehyde.

What is formaldehyde?

Formaldehyde has no color, but it has a pungent smell. It is very volatile at room temperature and has good swimming ability. Well-known formalin used for soaking biological specimens is formaldehyde solution.

How toxic is formaldehyde?

In addition to the damage to liver and kidney function, the carcinogenicity of formaldehyde is beyond doubt.

The World Health Organization (WHO) has identified formaldehyde as a carcinogenic and teratogenic substance, and formaldehyde ranks second in the priority control list of toxic chemicals in China.

According to the data of the US Centers for Disease Control and Prevention, although there is no clear scientific research data on the specific dose of formaldehyde causing malignant tumors, if you are exposed to formaldehyde for a long time, even at a low dose, the risk of cancer will greatly increase.

Moreover, formaldehyde will have a greater impact on children, pregnant women and the elderly.

Where does formaldehyde lurk around us?

Formaldehyde is widely used in industry because of its low price, which leads to a lot of items containing formaldehyde in our lives.

The first decoration materials and furniture have become the main sources of indoor formaldehyde pollution, especially newly renovated houses and newly bought furniture. The formaldehyde content is really high. At the same time, some common industrial products such as preservatives, carpets, paints and pickled products also contain formaldehyde.

In fact, practitioners in many related industries also have potential risks of exposure to formaldehyde. The manufacturing industry that is most exposed to formaldehyde is not only exposed to air with high formaldehyde concentration, but also exposed to liquid formaldehyde.

In addition, there are some occupations that can be exposed to formaldehyde, such as undertakers, medical personnel, teachers and students who make specimens in research rooms, and workers in clothing or furniture factories.

How does formaldehyde enter our body?

1. Breathe and inhale

When inhaling air containing formaldehyde, most formaldehyde will be decomposed by cells in the respiratory tract and exhaled. But when the concentration of formaldehyde is high, it will enter the blood through the respiratory tract.

2. Digestive tract intake

Formaldehyde in food or water will quickly enter the body through the digestive tract.

3. Skin contact

When exposed to liquid formaldehyde, a small amount of formaldehyde will penetrate through the skin.

Formaldehyde is rampant, how to hide?

1. No smoking

No matter what brand of tobacco, it contains formaldehyde. Only by quitting smoking can the harm of this part of formaldehyde be eliminated. Moreover, this kind of harm is not only aimed at smokers, but also indoor smoking will make people in the same room suffer from formaldehyde pollution.

2. Keep the house ventilated

Indoor building materials and furniture will release formaldehyde into the air. More ventilation can reduce the formaldehyde content, and try to use less pressed wood at home. When the formaldehyde content is high, it is extremely simple and effective to open more windows or use exhaust fans to make indoor air circulate.

However, ventilation is not everything.

The release cycle of formaldehyde is long, usually three to fifteen years. Therefore, it is unrealistic to try to completely eliminate indoor formaldehyde pollution after a few months of ventilation. This requires us not to be greedy and cheap when choosing decoration materials, choose regular manufacturers, try to reduce the indoor formaldehyde concentration, or check in after the treatment is completed. At present, pure plants such as Dialine or Ye Guang mud series are good choices. Once the indoor formaldehyde concentration is lower than the national standard of 0.08 mg/m,

3. New clothes should be watered.

Some non-ironing fabrics emit formaldehyde, but formaldehyde is very soluble in water. Washing clothes before wearing them can reduce the formaldehyde emission of non-ironing fabrics and remove most of the residual formaldehyde in clothes, thus reducing the risk of formaldehyde exposure.

4. Removal of diphenylamine plant liquid

The percolate is extracted from more than 20 kinds of plants such as aloe, Phyllostachys pubescens, Dictyophora dictyophylla, honeysuckle, wild chrysanthemum and dandelion. Without adding pure plants, the organic components in plant extracts react with formaldehyde to dehydrate, producing harmless stabilizers, which are absorbed and infiltrated to decompose harmful substances such as formaldehyde, benzene and TVOC. Safe and reliable, it is a good choice for in addition to formaldehyde to eliminate decoration pollution.
