油煙基本上是每個人日常都會接觸到的東西，畢竟人都要吃飯，除非你是不食人間煙火的仙人。 但你是否知道油煙包含了數種、有毒、有害甚至致癌的物質呢？ 實際上很多人都知道油煙對人體潛在著危害性，畢竟近年來網絡發展得異常迅速，大量有關油煙危害性的信息鋪天蓋地的出現在網絡的各個角落。 隨著人們對油煙危害性的逐漸認識，有一種獨特的見解忽然出現在網絡之上：油煙的危害性被夸大，這都是食品加工廠商家們的陰謀！
Oil smoke is basically something that everyone will come into contact with everyday. After all, people have to eat unless you are a fairy who does not eat human fireworks. But do you know that soot contains several toxic, harmful and even carcinogenic substances? In fact, many people know that oil fume is potentially harmful to the human body. After all, in recent years, the network has developed very rapidly. A large number of information about the harm of oil fume has appeared in every corner of the network. With the gradual recognition of the hazards of oil fumes, a unique view suddenly appeared on the Internet: the hazards of oil fumes are exaggerated, which is the conspiracy of food processors!

In fact, many people know that oil fume is potentially harmful to the human body. After all, in recent years, the network has developed very rapidly. A large number of information about the harm of oil fume has appeared in every corner of the network.
With the gradual recognition of the hazards of oil fumes, a unique view suddenly appeared on the Internet: the hazards of oil fumes are exaggerated, which is the conspiracy of food processors!
This view is not unreasonable, China has a thousand years of food culture, and foreign countries also have a long-standing eating habits; far from it, take our own life as an example, many people have their own cooking habits, daily exposure to a large number of lampblack, but there is no serious respiratory disease.
Of course, this statement is not a complete denial of the potential hazards of oil fumes. It is an indisputable fact that oil fumes do contain unsaturated hydrocarbons, saturated hydrocarbons, polycyclic aromatic hydrocarbons, heterocyclic compounds, alcohols, aldehydes and other toxic and carcinogenic substances in the detection of scientific instruments.
So, is the harmfulness of soot really exaggerated?
As ordinary people, can we really ignore the oil fumes rolling out in the pot?
In fact, the reason for purifying oil fume is not only to protect human health, but also to protect the natural environment.
WHO has made a statement: in China, one of the main sources of air pollution from cooking fume purifiers is fume purification.
As early as 2013, when Beijing was still full of haze, a scientific survey was conducted. In Beijing, where haze was serious and PM2.5 burst, the contribution of PM2.5 from catering sources has reached 13%. This figure has been comparable to the ground dust and industrial PM2.5 emission in Beijing. In addition, the PM2.5 emission of motor vehicles and coal-fired has reached 25% and 19%.
So in recent years, in order to pursue a better quality of living environment and urban outlook, both Beijing and large cities have begun to reduce emissions, restrict travel, rectify food and beverage emissions, and promote low-carbon travel and other measures.
Although the cooking fume produced by people's daily cooking does not cause much harm to the human body, after all, the cooking time will not be too long, but for some cooks who need to work in exhaust gas all the year round, the amount of fume they face is unimaginable.
According to statistics, taking a small and medium-sized hotel in Beijing which operates six hours a day as an example, according to Beijing's smoke emission standard of 2mg/m, the smoke emission of this hotel can easily exceed 100 kg a year!
If the hotel fails to comply with the regulations and emit oil fumes at will, its annual oil fume emissions are calculated at a multiple of 1,000 kg. There are tens of thousands of such small and medium-sized hotels in Beijing. Without restriction, these hotels alone will bring tens of millions of tons of oil fumes into the outdoors in a year, and the staff in the kitchen will be covered with oil fumes every day. In the environment, it is a terrible sight.
China's catering industry is also changing with each passing day, and the smoke discharged outdoors will only be more and more. Nature's self-purification ability is limited. Once beyond this limit, the ecosystem of nature will collapse. Finally, it's the human itself that is unlucky.
In addition, with the deterioration of the global environment, countries have also carried out various degrees of environmental remediation measures. Obviously, the development theory of pollution first and then pollution control is not in line with our development strategy, so our country has also increased the efforts to control the environment and prevent environmental deterioration, among which, lampblack control is one of the links.
So, how to rectify the problem of lampblack?
There are three main sources of lampblack: 1. family; 2. restaurant; 3. kitchen;
Although the number of families is large, but each family produces a limited amount of oil fume every day, and supervision is difficult, so at present our country has not paid too much attention to the treatment of family oil fume.
For restaurants and food processing factories, which produce a large amount of oil fume every year, China has issued several laws and regulations to restrict their production behavior, which should not have too great impact on the environment.
The emergence of indoor appliances is just an industry equipment that conforms to this trend, so there is no conspiracy.
