The air pollutants produced by indoor decoration will not cause people to get sick or die immediately, but their toxicity is chronic. Living and working in a problematic indoor environment for a long time will affect people's immunity, and the accumulation of toxic substances in the human body will lead to human illness. So what harm does decoration pollution do to us? What are the renovation pollution control methods? Let's take a look at it with Xiaobian.

Harm of decoration pollution

Indoor decoration pollution mainly comes from indoor building materials and furniture, such as plywood, particleboard, foam filler, wood floor, wallpaper, paint and coating. These decoration materials will emit formaldehyde, benzene, ammonia, TVOC, etc., among which formaldehyde has been identified as carcinogenic and teratogenic by the World Health Organization.

The main harm of formaldehyde is the irritation to skin and mucous membrane. Formaldehyde is a toxic substance in protoplasm, which can combine with protein. When inhaled in high concentration, it will cause severe irritation to respiratory tract, edema, eye irritation and headache. Among all the contacts, children, pregnant women and the elderly are particularly sensitive to formaldehyde, and the harm is even greater.

Benzene and TVOC mainly come from adhesives used in paints, paints and furniture, which affect the central nervous system and cause dizziness, headache, weakness and chest tightness. Sensory irritation, unpleasant odor, irritation to upper respiratory tract and skin.

ammonia mainly comes from antifreeze and urea added in concrete during construction. Inhaling a large amount of ammonia in a short period of time will cause symptoms such as tears, sore throat, hoarseness, cough, dizziness, nausea, etc. In severe cases, pulmonary edema or respiratory distress syndrome will occur, and respiratory irritation symptoms will occur at the same time.

pollution control methods for decoration

1. Open more windows for ventilation

A lot of pollutants such as formaldehyde will be released in the early stage after decoration. At this time, the easiest way is to open windows for ventilation, and when appropriate, you can turn on the electric fan to accelerate indoor and outdoor air circulation.

advantages: it is the most economical and practical way to eliminate most harmful gases such as formaldehyde, which is simple and convenient.

Disadvantages: it takes a long time, the effect is slow, and it is greatly influenced by the weather.

2. Plant absorption

More plants can be cultivated indoors. Plants can absorb some pollutants such as formaldehyde, which can purify the air, but it is only a trace effect and cannot be absorbed mainly by plants.

advantages: it can absorb trace pollutants such as formaldehyde, and it has the function of ornament and decoration, which makes people feel happy.

disadvantage: it can only play an auxiliary role.

3. Activated carbon

Activated carbon is widely used in sewage treatment and decoration pollution, and it has been fired in recent years, which is also a common method in in addition to formaldehyde. The price is cheap, but it is easy to saturate, but Maya Blue can make up for this shortcoming in this respect, but the price will be relatively expensive.

advantages: small size, solid, can be placed at will, and cheap.

Disadvantages: it is easy to saturate, and the use time is short.

4. Photocatalyst

Photocatalyst is one of the better methods in in addition to formaldehyde so far. Photocatalyst is a catalyst. Under the action of this catalyst, harmful gases will be decomposed into harmless substances such as water and carbon dioxide when they meet air.

advantages: long durability and quick response.

Disadvantages: At present, the market is mixed, and it is easy to buy bad products. If unqualified products are used, it will easily cause damage to furniture and secondary pollution.

5. Purifier

The air purifier is very expensive, and after several months of use, the effect will obviously decline, and finally it will not work. In fact, the air purifier basically uses activated carbon to deodorize and detoxify, and the air purifier is only useful when it is electrified. For some closed places such as drawers and cabinets, it has started to work.

advantages: harmful substances such as formaldehyde can be removed.

Disadvantages: the price is expensive, the use time is short, and the hidden places are not involved.
