by:BOQU     2023-03-29
Residual chlorine means that after chlorine is put into water, in addition to consuming a part of the amount of chlorine with bacteria, microorganisms, organic matter, inorganic matter, etc. in the water, there is still a part of the amount of chlorine remaining. There are three kinds of compounds, NH2Cl, NHCl2 and NHCl3, NHCl2 is more stable and has a good bactericidal effect), also known as combined residual chlorine; free residual chlorine refers to OC1+, HOCl, Cl2, etc. in water, with fast sterilization speed and strong bactericidal effect , but disappears quickly), also known as free residual chlorine; total residual chlorine is the sum of combined residual chlorine and free residual chlorine. Potential harm of chlorine added to water and residual chlorine to human body 1. What is the main way of disinfection and sterilization of tap water at present? Answer: China's current tap water purification method: chlorine gas sterilization; tap water purification method in developed countries and regions in the world: ultraviolet and ozone technology sterilization. 2. Why is chlorine added to tap water? Answer: Tap water should be a kind of hygienic and safe drinking water. However, due to environmental pollution, bacteria and other harmful substances in the water will grow in large numbers. In order to inhibit and kill the bacteria in the water, chlorine is added during the water treatment process. 3. What harm does chlorine do to the human body? Answer: Chlorine gas is seriously harmful to the human body. It can irritate the eyes, nose, throat and upper respiratory tract. It can cause acute pulmonary edema and pneumonia. When the concentration is high, it can paralyze the respiratory center and cause 'lightning death'. Long-term inhalation of low-concentration chlorine will cause chronic poisoning, resulting in a large number of free radicals in the body and accelerating the aging of the human body. The main symptoms are rhinitis, chronic bronchitis, emphysema, liver cirrhosis, atherosclerosis, and even cancer. After chlorine is added to water, it will make your hair dry, broken, and split ends, and it will also cause your skin to bleach, peel off the skin layer, and produce extremely itchy psoriasis allergies. When chlorine is heated, it reacts with organic decay in water to produce carcinogens such as chloroform. 4. What is the effect of water containing residual chlorine on washing vegetables, fruits, grains, etc.? Answer: Chlorine will destroy nutrients such as vitamins and minerals in vegetables, fruits and grains, and seriously affect the absorption of nutrients by the human body. 5. How does residual chlorine enter the human body? A: Chlorine used in tap water can be easily and quickly absorbed by any oxidized surface with capillary pores such as skin, nostrils, mouth, lungs, hair, eyes, meat, vegetables, fruits and vegetables. 6. Why is residual chlorine easily absorbed through human skin? Answer: Because the surface of human skin is covered with pores and sweat glands, residual chlorine can easily enter through these tiny pores and be absorbed by human skin at the moment of contact with tap water. 7 What are the dangers of bathing with chlorine-containing water for a long time? Answer: Take a bath with tap water containing residual chlorine. 40% of the total amount of chlorine in the bathroom is inhaled through the respiratory tract, and 30% is absorbed through the skin, which is 6-8 times the amount of chlorine that enters the human body through drinking. In mild cases, itching occurs. Over time, the cancer-causing rate will increase by 30% in middle age; 8. Why do you say that tap water is more harmful after it is boiled? Answer: Boil the tap water. After the chlorine is heated, it will produce carcinogens such as chloroform with the organic decay in the water. The chloroform will increase by 3 to 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 being heated and boiled for drinking; the carcinogens in our body have increased by 3 to 4 times. 9. 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 and other symptoms. 10. What harm does residual chlorine do to children? Answer: When bathing children with tap water, chlorine will cause dryness, breakage and bifurcation of the hair, as well as bleaching of the skin, exfoliation of the skin layer, and itchy psoriasis allergies; when chlorine interacts with organic substances, such as sweat When the chlorine is inhaled into the lungs through the respiratory tract, it will damage the respiratory cells (Clara cells), leading to asthma and emphysema. 11. What harm does residual chlorine do to pregnant women? Answer: Pregnant women who drink tap water containing chlorine for a long time will affect the growth of the fetal heart and lungs, which may lead to arrhythmia, heart failure, and lung dysfunction in the newborn. 12. What harm does residual chlorine do to the elderly? Answer: It can lead to atherosclerosis, heart failure, arteriosclerosis, heart disease, bladder cancer, liver cancer, rectal cancer, and high blood pressure.
