Cities have been disinfected one after another. Why did Jinan order the demolition of disinfection channels in the community?

Because the existence of disinfection channels can not really kill the virus, and the risk to people is incalculable, which may lead to other physical diseases of non-infected people.

At the press conference in National Health Commission, Zhang Liubo, director of the Disinfection Center of the Institute of Environment, told us clearly that disinfection is indeed an important means to cut off the route of transmission, but it must be targeted. For example, it is of little significance to disinfect streets in some places. ? He also stressed that if disinfectants are used to disinfect the air, it must be in an unmanned environment. ? If someone inhales disinfectant or sprays disinfectant on everyone during disinfection, we can't quantitatively assess the risk. ?

As we all know, 75% alcohol is not suitable for indoor disinfection, so as to avoid fire accidents caused by excessive air density. Therefore, the disinfection channels in these communities are mostly disinfected with chemical disinfectants. But people often don't stay in the channel for too long, and they can't kill the virus at all.

In fact, the Health and Health Commission has warned that air disinfection needs to be carried out in an unmanned environment, and the disinfection channels in the community are busy, which does not meet such requirements.

Chemical disinfectants can kill COVID-19 virus, but they can also cause harm to human body. These chemical disinfectants can enter the human body through the air, stimulate the respiratory tract, damage the respiratory mucosa, and make people more susceptible to viruses. Moreover, the harm of these chemical disinfectants to human body is uncontrollable, especially some disinfectants use high-concentration disinfectants to achieve the effect of killing viruses, which is even more harmful to human body.

It can't kill the virus in the air, but it will do immeasurable harm to the human body. Of course, such a disinfection channel has to be dismantled.

In fact, as long as you do a good job of protection, wear a mask, wash your hands in time after you come out, and disinfect the surfaces and articles you often contact in time, which is far more useful than building any disinfection channel.
