Indoor air pollution

There are more than 900 types of indoor air pollutants, which are mainly divided into 3 categories:

1. gaseous pollutants. When the indoor ventilation conditions are poor, the gas pollutants will accumulate indoors, and the concentration will increase.Some concentrations can exceed the health standard dozens of times, causing serious indoor air pollution.

2. Microbial contaminants. Such as allergic reactions, viruses, fungi and microorganisms that are easy to breed in indoor humid places.

3. Respirable particulate matter (PM10 and PM2.5).

1. Sulphur dioxide (SO2) and nitrogen dioxide (NO2) are harmful to the respiratory tract.

2. Carbon monoxide (CO) in addition to causing acute poisoning, its chronic effects are damage to the myocardium and central nervous system.

3. Particulate matter contains large amounts of polycyclic aromatic hydrocarbons (PAHs), many of which are carcinogens.

Formaldehyde is a common indoor VOCs, colorless, irritating, soluble in water, and can react with amino acids, proteins, and DNA, thereby destroying cells. Low concentrations of formaldehyde can have acute adverse effects on the human body, such as headache, tearing, coughing and other symptoms, and high concentrations of formaldehyde can cause allergic asthma. Long-term inhalation of a certain concentration of formaldehyde also has carcinogenic effects.

1. indoor activities

2. Interior supplies: daily life and office supplies; building materials; furniture, decorative items and furnishings.

3. exhale

No heavy metal-containing raw materials are used, which is consistent with the standard of children's toys, and can be degraded after use without polluting the environment.
