Question 4: Is ozone disinfection harmful to people? Ozone does have a disinfection effect.
Ozone, also known as oxygen-enriched, trivalent oxygen and superoxide, is one of the strongest oxidants known to be available. It can oxidize and denature the protein shell of bacteria and fungi, thus killing bacterial propagules and spores, viruses and fungi. Ozone can kill more than 99% of Escherichia coli, Streptococcus and Staphylococcus aureus, and can kill hepatitis virus and cold virus. Ozone has outstanding sterilization, disinfection and degradation of pesticides, and is considered as an efficient broad-spectrum fungicide.
Ozone can sterilize and purify the air, prevent cross-infection of diseases, and remove the peculiar smell in bedrooms, living rooms, kitchens and bathrooms. Ozone gas has the functions of sterilization, disinfection, mildew prevention and dust mites removal for indoor bedding, clothes, carpets, wardrobes, shoe cabinets and coins.
The most suitable method for disinfection and sterilization by ozone is to dissolve ozone in water to form so-called "ozone water". Some developed countries in Europe and America call "ozone water" universal water. The sterilization speed of "ozone water" is many times faster than chlorine. In daily life, using "ozone water" to disinfect underwear, diapers and bags used by women and children can have a particularly obvious effect. "Ozone water" has the functions of sterilization, preservation and odor removal for fruits, vegetables and meat, and also has the function of degrading phosphorus-containing pesticides on the surfaces of fruits and vegetables. We can also use "ozone water" to clean and maintain the skin and reduce the * * * effect of cosmetics on the skin. Cold compress and soaking burns, cuts and lumps with "ozone water" can accelerate wound healing and prevent infection; Washing bubbles with "ozone water" can prevent dermatosis and beriberi caused by fungi; Washing your hair with "ozone water" can remove dirt from the capillaries of your hair and reduce hair loss.
Scientific use is harmless.
According to experts, the safety and environmental protection of ozone have been recognized, and its application technology is quite mature. Br> If used scientifically, ozone will not do harm to human health.
In many countries, ozone is widely used in drinking water disinfection, air purification, food processing, medical care, aquaculture and other fields.
1902, the first large-scale water plant using ozone to treat water quality was established in paderborn, Germany, which pioneered the ozone water treatment. Now, there are thousands of ozone water plants in the world. The application of ozone in European and American waterworks has reached a universal level, and almost all mineral water and purified water manufacturers are equipped with ozone equipment. Since the early 1970s, the United States began to use ozone to treat domestic sewage, mainly for sterilization, decontamination, decoloration, etc. to meet the discharge standards. In Japan, sewage is treated by ozone and used as reclaimed water in water-deficient areas. The United States, Japan, Germany, France and other countries have established large-scale ozone sewage treatment plants in recent years.
Was ozone still the industry leader when writing frame 3? Psst? ぁ⑹? What's wrong with Ting? Ellipse? ⑾ 懔? In br> industry, the application of ozone in food industry is more popular. A Swedish beef company applied ozone to the storage and preservation of beef, starting from 1870. As early as 1904, Europe used ozone to preserve milk, meat products, cheese, protein and other foods. In the late 1930s, ozone generators were installed in 80% frozen egg banks in the United States. A few days ago, European and American countries used ozone in the storage, manufacture and transportation of fruits and vegetables.
In medical treatment, Japan used ozone for physical therapy as early as World War II. At present, ozone has many uses in medical care, such as air disinfection in wards and operating rooms, disinfection of medical instruments with ozone water, treatment of dental diseases with ozone, treatment of cancer with ozone combined with radiotherapy, treatment of gynecological diseases with ozone water, and injection of ozone gas to treat fistula, hemorrhoids and varicose veins. In terms of health care, it is popular in Japan to inhale "strong air" (air with low ozone concentration) to strengthen the body and spray the body with ozone water for sterilization and beauty.
Ozone can kill viruses and bacteria, but it does no harm to healthy cells, because the latter has a powerful balanced enzyme system. As long as ozone is used scientifically, there is no danger to human health. In fact, ozone has been used 100 years, so far there has not been an accident of death due to ozone poisoning in the world.
In addition, there is a saying that ozone can "kill" vitamins and other beneficial components in fruits and vegetables while disinfecting; However, it was confirmed by the Institute of Environmental Health Monitoring of Chinese Academy of Preventive Medicine that qualified ozone equipment was used to soak fruits normally ... >>
Question 5: What harm does ozone do to people? Brief Introduction to Ozone Ozone, also known as triatomic oxygen, commonly known as "oxygen-enriched, superoxide and active oxygen", is an allotrope of oxygen (O2) with the molecular formula O3. Ozone is a light blue gas at normal temperature and pressure, accompanied by fishy smell. The stability of ozone is very poor, and it can be decomposed into oxygen at room temperature, so ozone cannot be stored. Generally, it is produced on site and used immediately. Ozone is a broad-spectrum, efficient, fast, safe and non-secondary pollution sterilization gas, which can kill bacterial spores, viruses, fungi and so on. And destroy the botulinum toxin. It can kill Escherichia coli, Staphylococcus aureus, Salmonella, Aspergillus flavus, Fusarium, Penicillium Iceland, black mutant spores, natural bacteria, Neisseria gonorrhoeae, etc. Attached to fruits, vegetables, meat and other foods, it can also kill infectious viruses such as hepatitis A and hepatitis B, and also remove the toxicity of pesticide residues and detergent residues in fruits and vegetables. The mechanism of sterilization is to act on the cell membrane of bacteria, so that the components of the cell membrane are destroyed, leading to metabolic disorder and inhibiting its growth until death. The mechanism of killing virus is to directly destroy its ribonucleic acid or deoxyribonucleic acid. The mechanism of pesticide degradation is achieved by directly destroying its chemical bonds. Ozone can kill viruses and bacteria, and healthy cells have a strong balance system, so ozone is less harmful to healthy cells. The molecular formula is O3, which is an unstable and very active gas. Ozone is light blue and has a faint smell of grass. A small amount of ozone in the atmosphere can be produced under some natural and man-made conditions. Including lightning, the influence of sunlight on smoke components, ultraviolet rays and water electrolysis. So people will think that the fresh air in the forest, along the coast and after thunderstorms and lightning is the function of ozone. The characteristics of ozone A, the chemical properties of ozone are extremely active, and its oxidation ability is second only to fluorine. When its atoms are free, it can produce strong oxidation in an instant, which can sterilize, deodorize, detoxify and bleach. And combine with oxidizing substances. B, ozone is a broad-spectrum and efficient disinfectant, which can quickly and thoroughly kill bacteria in air, water and objects. Ozone also has the functions of decoloring, deodorizing (odor), deodorizing (odor), removing some heavy metal ions, and degrading toxic and harmful organic substances such as pesticides and fertilizers. C ozone is easily soluble in water, and its dissolution rate in water is 13 times that of oxygen. After ozone is dissolved in water, its bactericidal power is stronger, and its bactericidal power can reach 600-2000 times that of chlorine. D, ozone is easy to decompose and reduce to oxygen. The half-life of ozone is about 5-20 minutes in water and about 10-30 minutes in air. Ozone will eventually decompose into oxygen. Ozone will not cause harm and secondary pollution. Ozone is a safe natural disinfectant. Moreover, the ozone content in the ozone water produced by the "Shuiyan" ozone sterilizer is 0.7 mg/l, which is lower than the standard of1.0 mg/L. After the ozone itself reacts, it will be quickly reduced to oxygen, so there is no need to worry about chemical residues and it will not pose any threat to the living environment. Only ordinary oxidants and chemical disinfectants need to consider the safety of secondary products and the pollution caused by adhesion to food. Ozone not only has no secondary pollution, but also can make the air fresh and improve the environment. Use of ozone (1) Chemical properties and efficacy Ozone (O3) is an allotrope of oxygen, a light blue gas with a special smell. The molecular structure is triangular, the bond angle is 1 16, the density is 1.5 times that of oxygen, and the solubility in water is 10 times that of oxygen. Ozone is a strong oxidant, and its redox potential in water is 2.07V, second only to fluorine (2.5V), and its oxidation capacity is higher than chlorine (1.36V) and chlorine dioxide (1.5V). It can destroy the cell wall of bacteria, quickly spread into cells, and oxidize glucose oxidase. , which is necessary for oxidizing glucose in bacteria, can also directly react with chlorine dioxide. It destroys cells, ribonucleic acid (RNA), decomposes macromolecules such as deoxyribonucleic acid (DNA), RNA, protein, lipids and polysaccharides, and destroys the metabolism and reproduction process of bacteria. Ozone kills bacteria because of the rupture of cell membrane. This process is called cell dissipation, which is produced by the squeezing of cytoplasm in water. In the case of dissipation, cells cannot regenerate. It should be pointed out that, unlike hypochlorous acid disinfectants, the sterilization ability of ozone is not affected by the change of PH value and ammonia gas, and its sterilization ability is 600-3000 times greater than that of chlorine gas, and the sterilization effect is almost instantaneous. When the ozone concentration in water is 0.3-2 mg/L, it is 0.5->: >
Question 6: Is ozone harmful? Ozone (o? ), is oxygen (o? ), a light blue gas, has a special smell at room temperature. Ozone mainly exists in the ozone layer below the stratosphere 20 ~ 35 kilometers from the earth's surface. Under normal temperature and pressure, it has poor stability and can be decomposed into oxygen by itself. Ozone smells of grass. Inhaling a small amount is beneficial to human health, and inhaling too much is harmful to human health (nonflammable, pure). Oxygen can be changed into ozone by electric shock.
Harm to mankind
Low concentrations of ozone can be disinfected. Generally, the concentration of ozone in forest areas can reach 0. 1ppm), but ozone exceeding the standard is an invisible killer!
In summer, due to the influence of industrial and automobile exhaust, ozone will form and accumulate on the surface, especially around big cities and agricultural and forestry areas. Surface ozone has corrosive and damaging effects on human body, especially on eyes and respiratory tract. Surface ozone is also harmful to crops or forests.
▲ Ozone can * * * mucous membrane and is toxic to human body. It is unsafe to inhale air containing 0. 1ppm ozone for a long time.
▲ It strongly affects human respiratory tract, causing sore throat, chest tightness, cough, bronchitis and emphysema;
▲ Ozone can cause nerve poisoning, dizziness and headache, decreased vision, decreased memory, shortness of breath, fatigue and nosebleeds;
▲ Ozone will destroy vitamin E in human skin, causing wrinkles and dark spots on human skin;
▲ Ozone will also destroy the immune function of the human body, induce lymphocyte chromosome lesions, accelerate aging, and make pregnant women give birth to deformed children;
Therefore, people must attach great importance to the harm caused by ozone and organic waste gas.
The interests of mankind
Ultraviolet rays affect human health in many ways. Sunburn, eye diseases, immune system changes, light changes and skin diseases (including skin cancer) can occur in human body. Skin cancer is a stubborn disease, and the increase of ultraviolet rays will increase the risk of this disease. Ultraviolet photons have enough energy to break the double bond. Short-and medium-wave ultraviolet rays can penetrate deep into human skin, causing skin inflammation, destroying human genetic material DNA (deoxyribonucleic acid), transforming normal growth cells into cancer cells and continuing to grow into a whole skin cancer. Others say that sunlight penetrates the surface of the skin. Ultraviolet radiation bombards the basic unit of DNA in the skin nucleus, melting many units into useless fragments. The repair process of these defects may be abnormal, which may lead to cancer. Epidemiology has confirmed that the incidence of non-melanoma skin cancer in factories is closely related to sun exposure. People with all skin types are likely to suffer from non-melanoma skin cancer, but people with light skin have a higher incidence. Animal experiments have found that ultraviolet B wavelength region is the wavelength region with the strongest carcinogenic effect.
It is estimated that the total ozone will be reduced by 1% (that is, ultraviolet B will be enhanced by 2%), and the canceration rate of basic cells will be increased by about 4%. It is found that ultraviolet B can change the function of immune system. Some experimental results show that infectious skin diseases may also be related to the enhancement of ultraviolet B caused by ozone reduction. It is estimated that the total ozone will decrease 1%, the incidence of skin cancer will increase by 5%-7%, and cataract patients will increase by 0.2%-0.6%. Since 1983, the incidence of skin cancer in Canada has increased by 235%, and the number of patients with skin diseases in 199 1 year has reached 47,000. The director of the US Environmental Protection Agency said that the number of people who died of skin cancer in the United States in the next 50 years will increase by 200,000 compared with the previous forecast. Australians like sunbathing and tanning their skin. Although scientists have repeatedly warned that more sunlight will lead to skin cancer, they still like dark skin. Results People didn't wake up until the incidence of skin cancer in Australia was 1 times higher than that in other parts of the world. People suffering from skin cancer have accounted for 1/3 of the total number of cancer patients in the world.
The United Nations Environment Programme warned that if the ozone layer of the earth continues to decrease and thin at this rate, the proportion of skin cancer in the world will increase by 26% to 300,000 by the year 2000. If the ozone layer decreases by 10% at the beginning of the next century, the number of people suffering from cataracts in the world may reach 1.6 million-1.75 million every year.
Exposure to ultraviolet light may also induce measles, chickenpox, malaria, scab, mycosis, tuberculosis, leprosy and lymphoma.
The increase of ultraviolet rays will also lead to the death of marine plankton, shrimp and crab larvae and shellfish, leading to the extinction of some organisms. As a result of ultraviolet radiation, groups of rabbits will suffer from myopia and thousands of sheep will be blind. ...& gt& gt
Question 7: Is ozone a harmful gas? It is not a harmful gas. The ozone layer in the atmosphere plays a role in blocking ultraviolet rays. Ozone in life, low concentration can sterilize and purify the air, high concentration will make clothes fade and hurt the skin. After all, everything is measured.
Question 8: Is it harmful to your health to smell ozone for a long time? Ozone is also called triatomic oxygen, commonly known as "oxygen-enriched, super-oxygen, active oxygen".

Drinking water purification: Tap water is a kind of high-quality raw drinking water after ozone treatment. The residual chlorine in water can be removed only by introducing O3 for 2 minutes per liter of water, which can sterilize, disinfect, deodorize and remove heavy metals, prevent the formation of carcinogen chloroform and increase the oxygen content in water.
three
Disinfection and sterilization: Put the washed tableware into water and put for 20 minutes to remove detergent residue, kill bacteria and viruses, replace the electronic disinfection cabinet and avoid infectious diseases of tableware.
four
Deodorization: Because ozone has a strong oxidative decomposition ability, it can quickly and thoroughly eliminate various odors in air and water.
five
The adverse effects of ozone on human body are generally caused by high concentration or insufficient purity. Examples of ozone's adverse effects on human body are mostly industrial ozone used at home, and its concentration is dozens of times higher than that used in life, sometimes even hundreds of times. Too high a concentration will do harm to human body.
Question 9: Is it bad for you to smell too much ozone? Inhaling a small amount of ozone is good for your health, while inhaling too much ozone is harmful to your health.
Ozone will * * * mucous membrane, which is toxic to human body. It is unsafe to inhale air containing 0. 1ppm ozone for a long time.
It strongly affects the human respiratory tract, causing sore throat, chest tightness and cough, bronchitis and emphysema;
Ozone can cause people's neurotoxicity, dizziness, headache, decreased vision, memory loss, shortness of breath, fatigue and nosebleeds;
Ozone can destroy vitamin E in human skin, leading to wrinkles and dark spots on human skin.
Ozone can also destroy the immune function of human body, induce lymphocyte chromosome lesions, accelerate aging, and make pregnant women give birth to deformed children;
Question 10: Is ozone toxic? The concentration of ozone in the air at 0.5- 1ppm will cause a certain reaction, and after a long time, people will feel dry mouth and other discomfort, and the concentration at 1-4ppm will cause people to cough. For people with asthma, emphysema and chronic bronchitis, the harm of ozone is more obvious. As long as it's not in a closed room,
