At the end of the year-end, a fruit and vegetable washing machine that claims to be able to “remove more than 90% of pesticides and hormone residues in fruits and vegetables, fish and grains†has become a “new darling†for people, and major electronics stores and online malls have seen hot sales. scene.
“Deeply remove pesticide residues inside vegetables and fruitsâ€, “Removal of residual hormones, lean meat and hookworm viruses in meatâ€... Can fruit and vegetable washing machines be so amazing?
â– Question 1: Can you remove more than 90% of pesticide residues on the surface of fruits and vegetables?
Wang Shiwen, director of the Ozone Special Committee of the China Federation of Industrial Economics, said that the anti-virus principle of fruit and vegetable washing machines is to use ozone to decompose pesticide components. Although its efficacy in sterilization and disinfection is certain, 90% of the figures are obviously "days." Night Tan."
Wang Yanhong, director of the Safety and Environmental Quality Monitoring Center of the Agricultural Products of the Chinese Academy of Sciences [17.26 -0.80%], said that many years of experiments have proved that the fruit and vegetable washing machine can remove some pesticide residues on the surface of fruits and vegetables, and the higher the ozone concentration, the better the detoxification effect, but the household The removal force of the machine is also about 10% to 20%, not as high as 90%. For the deep residue inside the fruits and vegetables, the fruit and vegetable washing machine can not be as immediate as removing the residual pesticide on the surface.
■Question 2: Can you “wash†the pesticides and hormones in fruits and vegetables and meat?
Wang Shiwen said that the detoxification of fruit and vegetable washing machines can only be on the surface of fruits and vegetables and meat, and it is "impossible impossible" to say "deep into the interior". Most of the meat is washed, even if some of the lean meat and hormones are removed, it is also superficial, not deep, because the fruit and vegetable washing machine does not produce enough energy to make the water and Ozone enters fruits and vegetables and meat for cleaning. In this case, it is impossible to "wash" the deep things.
â– Question 3: Are there any side effects on the health of the human body?
According to industry insiders, although all these machines work in a similar way, due to the difference in the quantity and quality of ozone gas production, unqualified fruit and vegetable washing machines have great hidden dangers to the human body. The fruit and vegetable washing machine generates ozone molecules through high pressure, and the unqualified products are accompanied by nitrogen oxides. The nitrogen oxides as a carcinogen have a very stable molecular structure and are not easily decomposed, so if the concentration is too high, it will be human. Health poses a threat.
At present, some formal ozone utilization enterprises will inform consumers according to industry standards when presenting quality inspection reports. The control index of nitrogen oxides is generally "safe value" if it is less than 2.5%, and the human body has Harmful. However, only some responsible businesses currently provide consumers with test reports in this regard. Experts suggest that consumers should be cautious if they cannot provide test reports.
The Single Side Formwork Support system can bear the concrete side pressure from the single-sided formwork and transmit it to the substructure or foundation. It can be used in conjunction with all wall formwork. In addition, the SB single-sided bracket system can be used as a horizontal platform bracket with strong load-bearing capacity; all connecting parts can be directly installed on the single-sided bracket system.
