[Yujian Science Popularization] People must also prevent air pollution in the room

When it comes to air pollution, we often think of thick smoke, dust, smog, car tail gas, but do you know? In addition to outdoor air can be contaminated, if the indoor air is not carefully maintained, it is also easy to be polluted!

Various fuels used in kitchen cooking, such as coal, petroleum, liquefied gas, natural gas, wood, paper, etc., without completely burning and insufficient combustion when the oxygen supply is sufficient, it will produce carbon monoxide, carbon dioxide, nitrogen oxides, particles, particles, particles, granules, Dust, hydrocarbon compounds and other air pollutants.

Generally speaking, coal -fired pollution is the heaviest, oil and natural gas are second, and electricity pollution is the lightest. When the ventilation is good, the pollution is light, and the closed indoor pollution is heavier. Among them, the carbon dioxide concentration can be combined by hemoglobin in the blood, causing hypoxia in the human body, which can cause death in severe cases. The polygon aromatic hydrocarbon compounds in hydrocarbons, such as 3-benzene and 4-benzene, is a strong carcinogen, and the particle dust with small particle size can easily enter the human body through the respiratory tract, causing harm to the human body.

The gases emitted by the bathroom and the sewer contain hydrogen sulfide, methampiosiol, methyl sulfur glycol, ethylene, and pyrine, which are toxic, can cause vomiting and reduce appetite. When the hydrogen sulfide content in the air is 30 to 40 mg per cubic meter, it will cause eye and respiratory symptoms. If it is contacting for a long time under low concentration, a chronic poisoning reaction will also cause headaches, dizziness, memory and immune function.

Smoking is one of the important sources of indoor air pollution, which is positively related to the growth of lung cancer. It is known that tobacco and smoke contain 3800 ingredients, including hundreds of harmful substances such as nicotine, polygon aromatic hydrocarbons, fake wooden thief, arsenic, nickel, and chromium, and carbon dioxide and hydrogen cyanide.

Paper smoke also contains a considerable dose of radioactive substances, and half of the smokers with lung cancer are caused by radioactive substances. For long -term smokers, in addition to suffering from lung cancer, they can also cause a variety of cancers. Compared with smokers without smoking, the incidence of laryngeal cancer increases by 4.5 times, the incidence of oral cancer increases by 4.1 times. The incidence of cancer increases by 1.9 times.

Smoking also increases the incidence of cerebrovascular and cardiovascular disease. The incidence of gastric gastric gastric stomach is 2.8 times higher than those who do not smoke. In short, smoking is harmful to health, and passive smokers are also seriously threatened.

Therefore, for the health of yourself and his family, stay away from tobacco and reduce indoor pollution!
