How to improve the air quality of kindergartens?
Indoor air pollution in kindergartens can directly invade the human respiratory system, causing chronic bronchitis, allergic diseases, acute respiratory infections, asthma, lung cancer and other respiratory diseases.
(1) Inhalable particulates are suspended particles with a diameter of 0.5 to 10 microns in the air.
It can be suspended in indoor air for a long time. After being absorbed into the human body, about 50% of it can be adsorbed on the lung wall and penetrate into the deep part of the lung tissue, causing bronchitis, pneumonia, asthma, emphysema and lung cancer, leading to cardiopulmonary function decline or even failure.
The particle diameter of inhalable particulate matter is small, and the surface area is large. The secondary pollutants in inhalable particulate matter become more. A study in the United States shows that inhalable particulate matter pollution is directly related to people's life span. Statistics from 90 major cities in the United States show that for every 10 micrograms/cubic metre increase in PM10, the mortality rate increases by an average of 0.5%. Precious metals in dust can be deposited in young children's tender viscera and circulatory system, resulting in irreparable damage in adulthood.
(2) Prevention of bacterial air-borne diseases
There are many pathogenic microorganisms in indoor air. Their survival and pathogenicity can last for a long time. Because of the existence of pathogenic factors, the harm is greater. There are 14 common diseases transmitted by air, none of which poses a serious threat to children's health. Among them, hand-mouth disease, chickenpox, measles, diphtheria, meningitis, mumps, pertussis, influenza, pneumophilic Legionnaires disease (air-conditioning disease) and tuberculosis are the most common infectious diseases in kindergartens.
The main factors affecting indoor air quality in kindergartens are:
Facilities: furniture, carpets, household appliances, air conditioning;
B. Architecture: building materials, decoration materials;
C. Activities of children and young children: amines and hydrogen sulfide produced by sweat and enuresis of children; aerosols produced by coughing and sneezing; dust and bacteria adsorbed by plush toys; paint for wooden toys; chemical volatiles from plastic toys;
D. Cooking: Fume combustion products;
E. Chemical materials: detergents, pesticides, cosmetics, other sprays;
F. Invasion of outdoor air pollutants: automobile exhaust, building dust, pollen, dust storm, fog.
(3) Focus on controlling microbial contamination
The population of kindergartens is relatively dense, and the immunity of children is relatively poor. Therefore, we should focus on controlling microbial contamination in kindergartens. The characteristics of microbial contamination are as follows: firstly, the growth rate is fast, under suitable conditions, it grows in geometric series, up to 224 in a day and night, secondly, it has strong viability; thirdly, it has a wide range of existence; fourthly, it produces a large number of metabolites such as harmful gases, excess substances and so on during reproduction; fifthly, the variation rate is fast. In recent years, with the aggravation of environmental pollution and the emergence of bacterial mutation, human beings are unable to defend against it. SARS, which spread in some cities of China in 2003, is a proof.
Solving the problem of indoor air pollution in kindergartens includes eliminating pollution sources, circulating air and purifying air. In this regard, we need to take some practical actions to reduce indoor air pollution, and use some effective methods to improve the air quality of kindergartens.
It is not difficult to improve the air quality in kindergartens. It only needs some awareness and efforts to do so. You will find that there are some easy-to-use and good ways to do this. Let's start working hard to create a healthy environment for children.
Kerkang brand air purification, sterilization and disinfection devices include dust removal, sterilization, and removal of harmful gases, which meet the relevant air quality standards. This is a high-quality indoor air disinfection and purification product, which can make the total number of indoor air bacteria in kindergartens reach below 500/cubic meters, and can be reduced to less than 200 with special requirements. Its disinfection mechanism meets the requirements of the Technical Standards for Disinfection of the Ministry of Health and can meet the disinfection standards of hospitals. You can safely use it in kindergartens.
In addition to disinfection function, the product also has strong functions of dust removal, harmful gas removal and odor removal. The indoor air quality of kindergartens using this product can reach advanced standards and allow children to breathe freely and safely.
