Question 4: Is ozone sterilization harmful to people? Ozone does have the function of disinfection
Ozone, also known as oxygen-rich, triple oxygen, superoxide, is known to be one of the strongest available oxidants, which can make bacteria, fungi and other organisms of the protein shell oxidation and denaturation, so as to kill the bacterial propagation and germ cells, viruses, fungi and so on. Ozone kills more than 99% of Escherichia coli, Streptococcus, Staphylococcus aureus, and kills hepatitis viruses, cold viruses and so on. Ozone has prominent sterilization, disinfection, degradation of pesticides, is considered a highly efficient broad-spectrum bactericide.
Ozone can sterilize and purify the air, prevent cross-infection of diseases, and remove odors from bedrooms, living rooms, kitchens, and bathrooms. Ozone gas is effective in sterilizing, disinfecting, preventing mildew and removing dust mites on indoor bedding, clothes, carpets, closets, shoe cabinets, coins and so on.
The most appropriate way to use ozone sterilization is to dissolve ozone in water to form the so-called "ozone water". Some developed countries in Europe and the United States will be "ozone water" called "universal water". The sterilization speed of "ozone water" is many times faster than chlorine. In daily life, the use of "ozone water" for women, children use underwear, ***, diapers, bags and other sterilization treatment, can play a particularly obvious effect. "Ozone water" on fruits and vegetables and meat have sterilization, antiseptic, freshness, remove the role of odor, and at the same time has the function of degradation of fruits and vegetables surface residues of phosphorus-containing pesticides. We can also use "ozone water" to clean the skin, skin maintenance, to reduce cosmetics on the skin ***. The use of "ozone water" cold compresses, soaking burns, cuts, bruises, can accelerate wound healing, to prevent infection; the use of "ozone water" to wash the bubble, you can prevent skin diseases and fungi caused by foot fungus type of disease; with "ozone water "Hair washing, can remove the dirt in the hair pores, reduce hair loss.
Scientific use of no harm
According to experts, the safety of ozone, environmental protection has been recognized, the application of its technology is quite mature, grey ?br> scientific use, the ozone will not cause harm to human health.
In many countries, ozone is widely used in disinfection of drinking water, air purification, food processing, health care, aquaculture and other fields.
In 1902, Paderborn, Germany, established the first large-scale water plant with ozone treatment of water quality, creating a precedent for ozone water treatment. Now, there are thousands of ozone water plants in the world. Europe and the United States of America, the application of ozone has reached a popular degree of water plants, mineral water, pure water manufacturers are almost all equipped with ozone equipment. The United States since the early 1970s began to use ozone to deal with domestic sewage, mainly for sterilization, disinfection, removal of pollutants, decolorization, etc. to meet discharge standards. Japan will be in water-scarce areas with ozone treatment of sewage as water use. The United States, Japan, Germany, France and other countries in recent years have established a large-scale ozone sewage treatment plant.
Ozone is also used in the industrial gazami crab to write pith meteorite frame 3?fizz? The newest addition to the list is a new generation of ozone-depleting chemicals. The main service hours of the crab are (11) hours of service?br> industry, the application of ozone in the food industry is more popular. A Swedish beef company to ozone applied to the storage of beef freshness, since 1870 has been used until now. As early as 1904, the European use of ozone on the preservation of milk, meat products, cheese, egg white and other food preservation treatment. At the end of the 1930s, 80% of the refrigerated egg banks in the United States have installed ozone generators. Recently, Europe and the United States in the fruit and vegetable preservation will be the use of ozone to storage, manufacturing, transportation and other aspects.
In terms of medical care, Japan as early as World War II, the use of ozone for human physiotherapy. At present, ozone has a variety of uses in health care, such as wards, operating rooms, air disinfection, the use of "ozone water" for the disinfection of medical equipment, the use of ozone for the treatment of dental diseases, the use of ozone and radiation therapy combined with the treatment of cancer, drinking "ozone water" Treatment of women's diseases, injection of ozone gas treatment of fistula hemorrhoids, varicose veins and so on. In terms of health care, Japan's popular inhalation of "strong gas" (containing a low concentration of ozone in the air) to strengthen the body, the use of ozonized water to shower the body to kill bacteria and beauty.
Ozone can kill viruses and bacteria, and the healthy cells of the human body, because the latter has a strong balance of the enzyme system. As long as the scientific application of ozone, ozone is not dangerous to human health. In fact, ozone has been used for more than 100 years, and so far there has not been a single case of death due to ozone poisoning in the world.
In addition, there is now a theory that ozone in the disinfection at the same time, you can also "kill" fruits and vegetables in the vitamins and other beneficial components of the human body; but by the Chinese Academy of Preventive Medical Sciences Environmental Health Monitoring test confirmed that the use of qualified ozone equipment to normalize soak the fruit of the work of ....... >>
Question 5: What is the harm of ozone to people Ozone Introduction Ozone, also known as triatomic oxygen, commonly known as "Fukao oxygen, superoxide, live oxygen", is oxygen (O2) isotopes, the molecular formula is O3. Ozone at room temperature and pressure, a light blue gas, accompanied by a fishy smell, the stability of ozone is extremely poor, at room temperature can be decomposed into oxygen, so the ozone can not be stored, the general site production, immediate use. Ozone is currently known as a broad-spectrum, efficient, rapid, safe, no secondary pollution of the sterilization gas, can kill bacterial germs, viruses, fungi, etc., and can destroy botulinum toxin. Can kill attached to fruits, vegetables, meat and other food on the Escherichia coli, Staphylococcus aureus, Salmonella, yellow currant berry bacteria, Fusarium, Icelandic Penicillium, black variegated bacillus, natural bacteria, gonococcus, etc., but also kills the A, B and other infectious diseases such as hepatitis B and other toxins, but also remove the toxicity of pesticide residues on fruits and vegetables and residual residues of detergent products. The mechanism of sterilization is to act on the cell membrane of bacteria, so that the composition of the cell membrane is damaged, resulting in metabolic disorders to inhibit their growth until death; the mechanism of killing viruses is accomplished by directly destroying their RNA or DNA. The mechanism of pesticide degradation is realized by directly destroying its chemical bond. Ozone kills viruses and bacteria, while healthy cells have a strong homeostatic system, thus ozone is less harmful to healthy cells. Ozone, with the molecular formula O3, is a relatively unstable and very active gas. Ozone is light blue in color and has a grass-fresh odor. Small amounts of ozone in the atmosphere can be produced under certain natural and man-made conditions. These include: lightning, sunlight on smog components, ultraviolet light, and water electrolysis. Ozone is responsible for the freshness of the air in forests, along the coast, and after thunderstorms and lightning. Characteristics of Ozone A. Ozone is chemically very active, and its oxidizing ability is second only to fluorine. Its atoms can produce strong oxidizing effect in an instant when it is free, which can sterilize, deodorize, detoxify, bleach, etc., and combine with oxidized substances. B. Ozone is a broad-spectrum and highly efficient bactericidal disinfectant, which can rapidly and thoroughly kill bacteria in the air, water and on the surface of objects. Ozone also has the role of decolorization, taste (taste), odor (smell), removal of some heavy metal ions, degradation of pesticides, fertilizers and other toxic and harmful organic substances. C, ozone is easily soluble in water, its dissolution rate in water is 13 times that of oxygen, dissolved in water after the ozone has a stronger bactericidal ability, the bactericidal power of chlorine can be up to 600-2000 times. D. Ozone is very easy to decompose and reduce to oxygen. The half-life of ozone in water is about 5-20 minutes, in the air is about 10-30 minutes. Ozone will eventually decompose into oxygen. Ozone will not bring harm and secondary pollution Ozone is a safe, natural sterilization and disinfection agent. Moreover, the ozone content in the ozone water produced by the "Water Eye" ozone sterilizer is 0.7 mg/l, which is lower than the standard of 1.0mg/l. The ozone itself will be quickly reduced to oxygen by the reaction, so there is no need to worry about chemical residues, and will not pose any threat to the living environment. Instead of using the usual oxidizing agents, chemical disinfectants need to consider the safety of secondary products and the pollution caused by attaching to food. Ozone is not only free from secondary pollution, but it also freshens the air and improves the environment. Ozone uses (1) chemical properties and efficacy Ozone (O3) is an allotropic isomer of oxygen, it is a light blue gas with a special odor. The molecular structure is triangular, the bond angle is 116 °, its density is 1.5 times that of oxygen, and its solubility in water is 10 times that of oxygen. Ozone is a strong oxidant, it is in the water redox potential of 2.07V, second only to fluorine (2.5V), its oxidizing ability is higher than chlorine (1.36V) and chlorine dioxide (1.5V), can destroy the decomposition of bacterial cell walls, quickly diffuse into the cell, oxidative decomposition of bacteria inside the oxidation of glucose must be glucose oxidase, etc., but also can be directly with the bacterium, viruses and the role of. Destroy cells, ribonucleic acid (RNA), decomposition of deoxyribonucleic acid (DNA), RNA, proteins, lipids and polysaccharides and other macromolecular polymers, so that the metabolism of bacteria and the reproduction process is destroyed. Bacteria are killed by ozone due to the rupture of cell membranes, a process known as cellular dissipation, caused by the crushing of the cytoplasm in water, and the impossibility of cellular regeneration under the conditions of dissipation. It should be noted that, unlike hypochlorite disinfectants, the bactericidal capacity of ozone is not affected by changes in pH and ammonia, and its bactericidal capacity is 600-3000 times greater than that of chlorine, and its sterilizing and disinfecting effect occurs almost instantaneously, with a concentration of ozone in the water of 0.3-2mg / L, 0.5-...... >>
Question 6: Is ozone harmful Ozone (O?), is an allotropic isomer of oxygen (O?), at room temperature, it is a light blue gas with a special odor. Ozone is mainly found in the ozone layer in the lower stratosphere, which is 20-35 kilometers from the earth's surface. It is less stable at room temperature and pressure and can decompose into oxygen on its own. Ozone has a grassy flavor, a small amount of inhalation is beneficial to human health, inhalation of excessive human health hazards (non-combustible, pure matter) Oxygen can be changed into ozone by electric shock.
Hazards to humans
Low concentrations of ozone can disinfect. (Ozone concentrations in forested areas can be as low as 0.1 ppm.) But excessive ozone is an invisible killer!
During the summer months, surface ozone forms and accumulates, especially around large cities and in agricultural and forested areas, due to the effects of industrial and automobile emissions. Surface ozone has an erosive and damaging effect on the human body, especially on the eyes and respiratory tract. Surface ozone is also harmful to crops and forests.
▲Ozone can *** mucous membranes, it is toxic to human body, and it is unsafe to breathe in air containing 0.1ppm ozone for a long time.
▲ It strongly *** human respiratory tract, causing sore throat, chest tightness, cough, bronchitis and emphysema;
▲ Ozone can cause neurotoxicity, dizziness, headache, vision loss, memory loss, shortness of breath, fatigue, nose bleeds;
▲ Ozone can play a destructive role of vitamin E in the skin of human beings, resulting in wrinkles in human skin,
▲ Ozone also destroys the body's immune system, induces chromosomal changes in lymphocytes, accelerates the aging process, and causes pregnant women to give birth to deformed babies;
Therefore, the hazards of ozone and organic waste gases must be taken very seriously.
Benefits to humans
Ultraviolet light affects human health in many ways. The human body suffers from sun spots, eye diseases, changes in the immune system, photodamage reactions, and skin diseases (including skin cancer). Skin cancer is a persistent disease, and the growth of UV rays increases the risk of developing this disease. UV photons have enough energy to break double bonds. Short- and medium-wave UV rays penetrate deep into the skin, causing inflammation of the skin and damage to the body's genetic material, DNA (deoxyribonucleic acid), which causes normally growing cells to metamorphose into cancerous cells and continue to grow into whole skin cancers. It is also said that the sun's rays penetrate the top layer of the skin. Ultraviolet radiation bombards the basic units of DNA in the nuclei of skin cells, causing many of the units to dissolve into useless fragments. The repair process of these faults may become abnormal, leading to cancer. Epidemiology has confirmed that the incidence of factory non-melanoma skin cancer is strongly correlated with sun exposure. People with all types of skin are at risk of developing non-melanoma skin cancer, but the incidence is higher in light-skinned people. Animal experiments have found that in ultraviolet light, the ultraviolet B wavelength region is the wavelength region with the strongest carcinogenic effect.
It is estimated that a 1% reduction in total ozone (i.e., a 2% enhancement of UV-B) will increase the rate of underlying cellular cancer by approximately 4%. UV-B has been found to cause changes in immune system function. Some experimental results suggest that infectious skin diseases may also be associated with UV-B enhancement resulting from ozone reduction. It is estimated that a 1% reduction in total ozone would increase the incidence of skin cancer by 5-7% and cataracts by 0.2-0.6%. Since 1983, the incidence of skin cancer in Canada has increased by 235%, in 1991 the skin disease patients have been up to 4.7 million. The U.S. Environmental Protection Agency, said the United States in the next 50 years died of skin cancer, will be expected to increase 20 million people than in the past. Australians like to sunbathe and get a tan. Despite repeated warnings from scientists that sun exposure can lead to skin cancer, they are happy to go dark. As a result, Australians didn't wake up until the incidence of skin cancer was twice as high as anywhere else in the world. Skin cancer now accounts for one-third of all cancers worldwide.
The United Nations Environment Programme has warned that if the Earth's ozone layer continues to deplete and thin at this rate, the proportion of people with skin cancer worldwide will have increased by 26% by the year 2000, to 300,000 people. If the ozone layer decreases by a further 10% at the beginning of the next century, then the number of people suffering from cataracts worldwide is likely to reach 1.6-1.75 million per year.
Exposure to UV rays may also induce measles, chicken pox, malaria, scarring, fungal diseases, tuberculosis, leprosy, and lymphoma.
The increase in UV rays can also cause massive deaths of marine plankton and shrimp, crab larvae, and shellfish, resulting in the extinction of some organisms. Ultraviolet radiation can also result in myopia in flocks of rabbits and blindness in thousands of sheep... >>
Question 7: Ozone is not a harmful gas is not a harmful gas, the ozone layer in the atmosphere to block the role of ultraviolet light, the life of the ozone in the low concentration of sterilization and purification of air, high concentrations will make the clothing discoloration and damage to the skin. After all, everything is about a degree.
Question 8: long time smell ozone harmful to the body Ozone, also known as tri-atomic oxygen, commonly known as "Fukao oxygen, super oxygen, oxygen",
Molecular Formula
is O3. Ozone at room temperature and pressure, a light blue gas, accompanied by a natural fresh taste, the stability of the ozone is extremely poor, at room temperature can be decomposed into oxygen
Methods / Steps
The main function of the ozone
Food purification: degradation of fruits and vegetables, food residues of fertilizers, pesticides, and other toxic substances from the surface to the inside of the removal of antibiotics, chemical additives, and other harmful substances in the meat, eggs, Harmful substances such as antibiotics, chemical additives, hormones, etc. in meat and eggs
2
Drinking water purification: Tap water is a kind of high-quality drinking water after ozone treatment. Each liter of water only need to pass into the O3 2 minutes to remove residual chlorine in the water, sterilization, disinfection, deodorization, removal of heavy metals, to prevent the generation of carcinogens trichloromethane, increase the oxygen content of the water
3
Disinfection and sterilization: after cleaning the food and beverage utensils into the water pass into the O3 for 20 minutes to remove the residues of detergents, kill bacteria, viruses, alternative electronic sterilizer, to avoid the transmission of disease from food and beverage utensils
4
Deodorization: Because ozone has a strong oxidative decomposition ability, can quickly and completely eliminate the air, water, a variety of odors
5
Ozone has an adverse effect on the human body is generally too large a concentration or purity is not enough to cause. Ozone on the human body caused by the adverse effects of the case, most of the industrial ozone used in the family, its concentration is higher than the life of the ozone concentration of dozens of times, sometimes even up to hundreds of times. The concentration is too high and causes harm to the human body.
Question 9: The ozone flavor smells more on the body is not good Inhalation of a small amount of ozone is beneficial to the human body, but inhalation of excessive amounts of human health hazards.
Ozone can *** mucous membranes, it is toxic to the human body, long time in the air containing 0.1ppm ozone is not safe to breathe.
It strongly *** human respiratory tract, causing sore throat, chest tightness, cough, bronchitis and emphysema;
Ozone can cause neurotoxicity, dizziness, headache, vision loss, memory loss, shortness of breath, fatigue, nose bleeds;
Ozone can play a destructive role of vitamin E in the skin of the human body, resulting in wrinkles, black spots;
Ozone can also be used as an antioxidant. Black spots;
Ozone also destroys the body's immune system, inducing chromosomal changes in lymphocytes, accelerating aging, causing pregnant women to give birth to deformed children;
Question 10: Is ozone toxic? Ozone concentration in the air caused by a certain reaction of personnel concentration of 0.5-1ppm, for a long time will feel dry mouth and other discomforts, concentration of 1-4ppm will cause personnel to cough. For those who suffer from asthma, emphysema and chronic bronchitis, the danger of ozone is more obvious. As long as it is not in a small, airtight room,
