When it comes to air pollution, especially the office workers who live in big cities, they are familiar with the term ‘smog’. It can be said that everyone has learned the ability to ‘swallow the clouds and spit’ every day without knowing it. I don’t know how many harmful substances are sucked. Even those who have iron cores and lungs can’t help but absorb the “essence” of the heavens and the earth for a long time.

Outdoor air pollution cannot be ignored, and indoor air pollution should cause concern. Some people may be confused. The interior is a closed space. As long as the doors and windows are closed, how can it be polluted? Let’s see what factors are there.

Harmful substances such as formaldehyde generated in newly renovated rooms, and the emission of outdoor polluted air caused by air flow into indoors, indoor smoking, and other harmful gases, or the harmful gases generated by long-term closed doors and windows, cause indoor air pollution more than outdoor A serious and important factor.

With the development of science and technology, on the one hand, the indoor activities of human beings have greatly increased, and on the other hand, due to the serious pollution of indoor and outdoor air, they are always threatening human health. Indoor air pollution damage is not only our generation, but also affects our children. So, do you think air pollution has nothing to do with you? Do you still think that going out with a mask can avoid air pollution? Many people go out to wrap themselves very tightly, thinking that this can avoid pollution, but the indoors are also the focus of air pollution.

Life is breathing

A German man closed his breath for 22 minutes and 22 seconds, breaking the world record and not breathing in pure oxygen to close the air for 10 minutes and 12 seconds.

Breathing is invaluable for everybody we sit in. We inhale 12 cubic meters of air a day, which is equivalent to a 3 ton truck; and we breathe 28,800 times a day; we can not eat for 7 days, 3 Do not drink water in the day, but we can’t breathe for 3 minutes;

However, we spend 70% of the time indoors, for urban residents, 70% to 90% per day, home, office, shopping malls, cinemas, gyms, supermarkets, etc., so how is the indoor air to us? importance;

Cognitive Misunderstanding of Indoor Air Pollution

Misunderstanding 1: Cover the odor with air freshener

Air fresheners and perfumes can only mask the odor of pollutants. In fact, the original harmful pollutants still exist in the room, continue to affect and endanger the health of the body, and inferior air fresheners will become The source of indoor air pollution increases the degree of pollution.

Misunderstanding 2: There is odor and pollution

Among the toxic and harmful gases, some in the case of serious pollution, the concentration is greater than the human odor threshold, you can feel the obvious odor, some pollution due to their low concentration, the human sense of smell is not smelling of. At the same time, the complex smells of various substances mixed together are difficult to distinguish. Therefore, it is inaccurate to judge what pollution is by smell.

Misunderstanding 3: The use of environmentally friendly materials during renovation is not polluted.

Qualified materials mean that the content of toxic and hazardous substances is not exceeded, but not. Therefore, if the same material is used in a large amount in one room, the indoor air quality may be unqualified or even exceed the standard due to the additive effect.

Misunderstanding 4: Indoor planting can purify the air

It is generally believed that green plants have the effect of purifying air, sterilizing and vacuuming, and removing toxic substances. However, the action of plants is characterized by slow speed, long time, and very limited absorption. Some plants can produce some unpleasant smells indoors, pollen or consume oxygen in indoor air, but increase indoor air pollution.

Misunderstanding 5: Harmful gases come from renovation

This is an incorrect view. For example, the main source of ammonia is concrete with additives such as antifreeze, and ammonia can be released from human waste; cigarette smoke and kitchen smoke can produce formaldehyde, benzene, TVOC, etc. Contaminants. In China, due to the large number of applications of various benzene-containing solvents, the common presence of benzene in indoor and outdoor ambient air is relatively low. Relatively speaking, the proportion of benzene pollution generated by cigarette smoke is relatively low, but this indicates that the degree of indoor air pollution in China is more serious.

Misunderstanding 6: Purify the air inside the car with perfume

After the new car leaves the factory, the concentration of toxic gas in the car is high, and the volatilization time can last for more than 6 months, which can cause dizziness, nausea, drowsiness, cough, sneezing and other discomforts, and even lead to serious diseases such as leukemia. At present, many perfumes are not naturally extracted.

Misunderstanding 7: Fortunately

Everyone’s physical fitness and resistance adaptability are different. Not all people will develop in the same harsh environment, so some people are lucky. This is not true. According to surveys of relevant international organizations, indoor air pollutants that are harmful to health are found in 30% of new and rebuilt buildings in the world, and 68% of diseases are caused by indoor air pollution.

When it comes to air pollution, the first thing that people think of may be smog, PM2.5, dust, and formaldehyde, but they often overlook important points: microbial contaminants such as bacteria, fungi, and viruses. According to a report in the Journal of the Royal Society of B (Biosciences), the microbes that we ‘co-located’ include more than 7,000 bacteria and more than 2,000 fungi, many of which may induce various acute infectious diseases. Pathogenic bacteria. Indoor bacterial contamination is a serious threat to human health and can cause various diseases such as various respiratory diseases, asthma, and building syndrome.

Biological pollution

Definition: Pollutants, allergens and other pathogens and allergens that are harmful to humans and organisms pollute water, gas, soil and food, affecting biological production and endangering human health. For example, pollution caused by bacteria, aphids, SARS viruses, and avian influenza viruses.

Characteristics of biological pollution:

First, it is difficult to predict, and it is difficult to predict when and where foreign creatures will invade.

Second, the incubation period is long. After an alien invasion, the incubation period lasts for several years, even decades. Therefore, it is difficult to be discovered and it is difficult to follow up.

The third is destructive, unconsciously, various rashes, viral infections, etc. appear on the skin.

Biological pollution can be divided into: according to different species:

Animal pollution (mainly harmful insects, parasites, protozoa, aquatic animals, etc.)

Plant pollution (weed is the most common contaminant species, as well as certain tree species and algae, etc.)

Microbial contamination (including viruses, bacteria, fungi, etc.).


Indoor biological pollution includes bacteria, fungi (including fungal spores), filter viruses, dust mites, Legionella, animal dander and biologically active substances, Escherichia coli, Staphylococcus aureus and the like.

Biological pollution can be divided into four categories:

First, mold, it is the main cause of allergic diseases

The second is pollen from plants, such as the sycamore pollen mentioned above.

The third is bacteria and viruses carried by humans, animals, soil and plant debris.

The fourth is dust mites and hair and dander from cats, dogs and birds.

Raw material pollution

In the early stage of collection and processing of food raw materials, many bacteria are often attached to the surface, especially fruits, vegetables, meat and aquatic products with damaged surfaces. Cooking utensils and tableware are contaminated.

Processing pollution

Processed foods are mostly packaged foods, generally cleaner, but also subject to secondary pollution. When the sanitary condition of the kitchen is poor, the bacteria floating in the air will settle to the surface of the food; during the cooking process, if you do not pay attention to the separation of raw and cooked, the bacteria will be transferred from the fresh food or semi-finished products to the cooked food, causing the food to cross. Pollution; food cooking and processing personnel can directly or indirectly cause bacterial contamination of food through their hands, clothes, respiratory tract, hair, etc. if they do not pay attention to personal hygiene or infectious diseases; seasonings used in cooking and processing (such as soy sauce) ) and if water contains bacteria, it can also cause bacterial contamination of food.

Indoor pollution

For example: air conditioning pollution

When the air conditioner circulates through the air duct, the bacteria and microorganisms carried in it gradually become more and more, and a secondary pollution source is formed, which causes the bacteria to multiply.

Food contamination

Harmful microorganisms and parasites or eggs contaminate food, which can cause food to spoil or produce toxins, poisoning people after eating, or causing parasitic diseases.
