Indoor air pollution, injury and cancer!
In recent years, air pollution is serious, and the outside is often thick smog. The air quality monitoring webpage shows a red pass, and even a purple explosion! In the face of outdoor air pollution, you may choose to hide indoors and try to go out as little as possible. However, the indoor air actually has a variety of pollution, so don’t take it lightly. Let us look at the main sources of indoor air pollution.
Closed doors and windows can not stop PM2.5!
The first source of pollution is air pollution from the outside, with familiar particulate matter (PM). The suspended particles are measured in micrometers (μm), the suspended particles with a diameter of less than or equal to 10 microns are called PM10, and the suspended particles with a diameter of less than or equal to 2.5 microns are called PM2.5.
Why is this different? Because the damage of suspended particles to the human body varies according to their size. Our nasal filtration limit is about 30 microns, which can block hair and fine sand. The bronchial filtration limit is about 10 microns, which blocks pollen and mold. The limit of alveolar filtration is about 2.5 microns. PM2.5 is very small in size and can pass through the alveoli, directly into the blood circulation, which affects the whole body and causes a variety of injuries.
PM2.5 can adsorb harmful substances such as lead, cadmium, arsenic and manganese, which is very harmful to children. Because the proportion of children’s breathing and body weight is higher than that of adults, the time spent indoors is long. If there is too much indoor PM2.5, Children’s learning and language memory decline, it is difficult to concentrate, red eyes, dry itching, easy to have allergic conjunctivitis. The skin condition is worse and it is easy to redden and itchy. When the mucus of the respiratory tract increases, the bronchi will induce asthma. More than 50% of young children who die from pneumonia are associated with indoor air pollution.
The effect of PM2.5 on adults is also very comprehensive. In the respiratory system, it can cause asthma, lung cancer, and chronic lung obstruction. In the cardiovascular system, it is easy to cause angina, myocardial infarction, and arrhythmia. PM2.5 will increase our metabolism, gain weight and gain diabetes. PM2.5 also harms the brain, and it is easier to get diseases such as stroke, dementia, and neurodegeneration. The researchers found that for every 5 μg/m3 increase in PM2.5 exposure per year, the risk of death increased by 7%. Even in the case where the PM2.5 is lower than 25 μg/m 3 , there is such a correlation.
According to the World Health Organization, about 4.3 million deaths each year are related to indoor air pollution. Common causes of death include stroke (34%), ischemic heart disease (26%), chronic lung obstruction (22%), and pneumonia (12). %), lung cancer (6%).
The most troublesome thing is that the diameter of PM2.5 is much smaller than the gap between doors and windows. Even if the doors and windows are closed, the floating particles are completely open to the suspended particles. Stay indoors, still subject to the high concentration of PM2.5 outdoors!
Burning gas and candles inside will pollute the air.
The second source of indoor air pollution comes from indoor combustion. We cook in the house and warm in the winter. We need to burn gas stoves, stoves and other equipment. In the combustion process, carbon dioxide, nitrogen monoxide, nitrogen dioxide, sulfur dioxide, formaldehyde and the like are generated. If ventilation is poor, it may cause dizziness and headache.
Exhaust gases from steam locomotives often contain nitrogen dioxide (NO2), which enters the room through open windows. If the garage at home is next to the doors and windows, pay special attention to it.
A large number of volatile organic compounds (VOCs)
Have you ever smelled a taste when your home has just been renovated, just painted, or just put on new furniture?
Decorative partitions, cements, and furniture may have volatile organic compounds (VOCs). The most dangerous substance is formaldehyde. The formaldehyde is widely present in paints, coatings, partitions, wooden furniture and adhesives, especially high humidity and high temperature, which accelerates the volatilization of formaldehyde. Excessive exposure to formaldehyde can irritate the nose, throat, eyes, and skin, damage our respiratory tract, and are carcinogenic. These building materials and furniture may continue to release volatile organic compounds for months or even years.
Cleaning supplies are another source of indoor pollution. When cleaning the house, we will open the kitchen cleaner, the toilet cleaner, and wash it out. Then we will put a wax on the floor, put a fragrance in the toilet, or spray the insecticide in the corner. These daily necessities often contain volatile organic compounds, which easily irritate the skin and respiratory tract, and even affect the central nervous system, causing fatigue and dizziness, as well as liver and kidney function, causing chromosome damage.
Perfume, nail polish, nail polish, hair gel, deodorant, anti-mosquito, correction fluid, insecticide, brightener, computer, scented candle, etc., which are often used by everyone, are also sources of volatile organic compounds.
Spreading biological pollutants
In our living environment, bacteria, dust mites, molds, fungi and other organisms can be found everywhere, making people allergic or infected. For example, after heavy rain, wet carpets, walls, and ceilings may be moldy, and mold cells can be rotated around the city with the air. Bedding is not often changed, it will be mixed with a lot of dander and dust mites. At the toilets and sinks where water is accumulated, air conditioners, dehumidifiers, and air-conditioning filters are hotbeds of microbial growth. These indoor microorganisms may cause infectious diseases, which may cause allergies to adults and children, affecting the respiratory tract, skin, eyes, and nose. Waiting for health.
Cigarettes, incense burners, and aromatherapy are all sources of pollution!
Cigarettes release thousands of chemicals and compounds such as nicotine, tar, and carbon monoxide. Hundreds of these are toxic, and there are nearly one hundred carcinogens that can damage organs throughout the body. Not only smokers are smoked. People who are not smoking but smoke second-hand smoke are deeply affected. Nowadays, although there are regulations and regulations in public places, the family space should still pay attention. If the family wants to smoke, they must ask him to go outdoors and ventilate to avoid the smoke pollution of their families.
Incense burners and aromatherapy are of course also sources of indoor air pollution, and long-term exposure is definitely harmful to the health of the family.
Clean the air and work hard together!
After reading so many sources of pollution, everyone may be surprised. The original indoor air pollution is much more serious than we imagined, and it unwittingly infringes on our health. In order to reduce indoor air pollution, we must start from two aspects, one is to reduce pollution sources, and the other is to filter air.
