1. What is the main way of disinfecting tap water at present? A: China's current tap water purification method: chlorine gas sterilization; the world's developed countries and regions tap water purification methods: ultraviolet and ozone technology sterilization. 2. What is chlorine? A: Chlorine is yellow-green, with strong asphyxiating odor and toxic gases. It is a strong oxidant. It can form phosgene when it is in contact with carbon dioxide. It can be liquefied into liquid chlorine under high pressure. The density is 2.48kg/m3, the melting point is -102°C, the boiling point is -34.6°C. It is white smoke in the air. It is soluble in water, alcohol and ether, and its aqueous solution is called hydrochloric acid. 3. Why do you want to add chlorine in tap water? A: The tap water should be a kind of drinking water that is both hygienic and safe. However, due to environmental pollution, harmful substances such as bacteria in the water are abundantly produced. In order to suppress and kill bacteria in the water, chlorine is added during the treatment of water. 4. What harm does chlorine have on the human body? A: Chlorine is a serious hazard to the human body. It can irritate the eyes, nose, throat and upper respiratory tract. Causes acute pulmonary edema and pneumonia. When the concentration is high, it can paralyze the respiratory center and appear "striking death". Long-term inhalation of low concentrations of chlorine can cause chronic poisoning, resulting in a large number of free radicals in the body, speeding up the body's aging rate. The main symptoms are rhinitis, chronic bronchitis, emphysema, cirrhosis, atherosclerosis, and even cancer. When added to water, chlorine can cause dryness, breakage, and splitting of your hair. It also bleaches your skin, peels off the skin layer, and produces itchy skin allergies. After the chlorine is heated, the organic humus in the water produces carcinogens such as chloroform. 5. What is the effect of water containing residual chlorine on washing vegetables, fruits, grains, etc? Chlorine destroys nutrients such as vitamins and minerals in vegetables, fruits and grains, and seriously affects the body's absorption of nutrients. 6. How does residual chlorine enter the body? A: It is used for chlorine in tap water. It is easy to absorb quickly on any oxidized surface such as skin, nostrils, mouth, lungs, hair, eyes, meat, vegetables and fruits. 7. Why is residual chlorine easily absorbed through human skin? A: Because the surface of human skin is covered with pores and sweat glands, the residual chlorine can easily be absorbed by human skin through these tiny pores at the moment of contact with tap water. 8. What is the hazard of taking a bath with residual chlorine for a long time? A: Take a bath with tap water containing residual chlorine. 40% of the total chlorine in the bathroom is inhaled through the respiratory tract. 30% is absorbed by the skin. It is usually 6-8 times of the chlorine in the body through drinking. It is itching. The carcinogenic rate will increase by 30% in the middle age. 9. Why is it more harmful after the tap water is boiled? A: The tap water is boiled. After the chlorine is heated, the organic humus in the water produces carcinogens such as chloroform. The chloroform will increase by 3-4 times compared with the tap water. If the residual chlorine cannot be removed, the coffee and tea we drink every day. Or soup, after boiling and drinking, we have 3 to 4 times more carcinogens in our body. 10. What diseases can be caused by drinking water containing residual chlorine for a long time? A: Heart disease, coronary atherosclerosis, anemia, bladder cancer, liver cancer, rectal cancer, high blood pressure and allergies. 11. What harm does residual chlorine have on children? A: When using tap water to bathe children, chlorine can cause dryness and breakage of hair, and it can also bleach the skin, peel off the skin layer and produce itchy skin allergies; when chlorine interacts with organic substances such as sweat At the time, it is easy to cause the formation of nitrogen trichloride in the surrounding air, which is very easy to damage the eyes and scorpions; chlorine inhalation into the lungs through the respiratory tract will damage the respiratory cells (Clara cells), which in turn leads to asthma and emphysema. 12. What harm does residual chlorine have on pregnant women? A: Long-term consumption of tap water containing chlorine in pregnant women may affect the growth of fetal heart and lungs, which may lead to arrhythmia, heart failure, and pulmonary dysfunction in newborns. 13. What harm does residual chlorine have on the elderly? A: can lead to atherosclerosis, heart failure, arteriosclerosis, heart disease, bladder cancer, liver cancer, rectal cancer, high blood pressure.
