Times are advancing and technology is developing at a rapid pace. Humanity has defeated many diseases that were previously considered terminal diseases. However, there are still some diseases, especially cancer, that are very difficult to treat, causing us to talk about cancer in a disgraceful way.
Generally, as long as you maintain good living habits, cancer will not easily come to your door. However, there are always people around you who live healthy and regular lives and do not smoke. However, they suffer from lung cancer. Not only do they suffer physically, but their families also suffer. Will be worried.
Then why do they get lung cancer?
Kitchen fumes can induce lung cancer
Relevant data show that among the factors that cause lung cancer, kitchen fumes are second only to "deep smoking" in the risk of smoke reaching the deep respiratory tract.
The composition of kitchen fume is complex, mainly composed of more than 220 compounds such as aldehydes, ketones, hydrocarbons, fatty acids, aromatic compounds, heterocyclic compounds, etc. Most of them are toxic, such as heterocyclic amines, which are strong carcinogens.
Kitchen oil fume has a special form. It is an aerosol composed of three phases: gas, solid and liquid. It can float in the air for a long time and enter the human body through the human respiratory system. Kitchen fumes have two main effects on human health.
First, inhalation poisoning. It manifests as damaging the respiratory mucosa, reducing human immune function, and increasing the incidence of tracheitis, pneumonia, and emphysema.
Second, it is carcinogenic. In case-control studies in Canada, the United Kingdom and the United States, it was found that chefs in the catering industry are at greater risk of lung cancer, nasopharyngeal cancer and esophageal cancer; a case-control study of 672 female lung cancer cases in Shanghai found that cooking fumes may be related to urban Women are at higher risk of developing lung cancer.
Second-hand smoke increases the risk of lung cancer
Secondhand smoke refers to a mixture of smoke released from the burning end of cigarettes or other tobacco products and tobacco smoke exhaled by smokers. It is also the most widespread and serious form of indoor air pollution, and a major cause of death worldwide. Studies have pointed out that secondhand smoke contains more than 4,000 harmful chemicals such as tar, ammonia, nicotine, suspended particles, PM2.5, polonium-210, and dozens of carcinogens.
The "Report on the Health Hazards of Smoking in China" points out that non-smoking women who are exposed to second-hand smoke because their spouses smoke have a risk of lung cancer that is 1.27 times higher than that of people without second-hand smoke exposure. There is a sufficient causal relationship between second-hand smoke exposure and lung cancer.
American medical researchers recently published a research report pointing out that passive smoking is commonly known as "second-hand smoking"."Smoking" is more dangerous than previously known. Some women who live with smokers are 2.6 to 6 times more likely to develop lung cancer than the average person.
The World Health Organization determines that PM2.5 causes cancer
PM2.5 refers to particulate matter in ambient air with an aerodynamic equivalent diameter of less than or equal to 2.5 microns. PM2.5 has small particle size, large area, and strong activity. It is easy to carry toxic and harmful substances (such as heavy metals, microorganisms, etc.), and it stays in the atmosphere for a long time and is transported over long distances. Therefore, it has a negative impact on human health and the quality of the atmospheric environment. The impact is greater.
On October 17, 2013, the International Agency for Research on Cancer, a subsidiary of the World Health Organization, issued a report for the first time identifying air pollution as carcinogenic to humans and treating it as a common and major environmental carcinogen. However, although air pollution has been proposed as an overall carcinogen, its harm to the human body may be the result of the simultaneous action of several major pollutants it contains.
Air purification expert-negative ions
Anions are called "auxins" or "air vitamins". They are of great significance to environmental protection and are known as the "environmental police." Therefore, many countries use the negative ion content in the air as one of the indicators to measure the quality of air hygiene. According to the World Health Organization, the air is fresh and hygienic when the negative ions in the air reach 1000-1500 per cubic centimeter.
