An appropriate amount of residual chlorine can prevent the growth of microorganisms and ensure the safety of water quality. However, when the residual chlorine content in water is too high, it will cause many harms to human health, mainly including the following aspects:
Destruction of nutrients When the residual chlorine content in tap water exceeds the standard, it will destroy the minerals, vitamins and other nutrients, such as vitamin C and vitamin E, when used to wash fruits and vegetables. In the long run, it may cause the human body to absorb these nutrients and lack these essential nutrients.
Cause chronic poisoning When tap water containing residual chlorine is used for a long time, the residual chlorine reacts with organic acids and may produce harmful substances such as chloroform and organic lead compounds, which are potential carcinogens. Long-term accumulation may cause chronic poisoning of body organs and pose a threat to human health.
Affect the respiratory system Residual chlorine can cause harm to the human respiratory system, and symptoms such as difficulty breathing and itchy throat may occur. Severe cases may induce rhinitis, bronchitis and even emphysema. In addition, water vapor containing residual chlorine may also cause adverse reactions such as coughing and wheezing after being inhaled.
Damage to the skin Excessive residual chlorine content in water may irritate the skin, easily cause skin dryness, aging, acne and other problems, and may also cause allergic symptoms such as dermatitis and eczema. Prolonged contact with such water may also cause the skin layer to fall off, which is extremely harmful to skin health. Bathing with water containing residual chlorine can also cause hair to become dry, broken, and split.
Other health problems Impact on special groups Pregnant women: Long-term drinking of tap water containing residual chlorine will reduce resistance, affect the growth of the fetal heart and lungs, and may also cause neonatal arrhythmia and lung dysfunction. Children: Long-term drinking of chlorine water will not only hurt the stomach, but also affect nutrient absorption. Moreover, the strong oxidizing hypochlorous acid produced by the reaction of chlorine and water will damage brain cells and affect their development. In addition, chlorine can easily be inhaled into the lungs through the respiratory tract, damaging respiratory cells, and easily leading to asthma and emphysema. Bathing children with water containing residual chlorine will cause their hair to become dry, broken, split, their skin to bleach, their skin to fall off, and they will have allergies. Elderly people: Long-term consumption of chlorinated water is prone to heart disease, coronary atherosclerosis, hypertension and other diseases, and it is also easy to damage the liver and kidneys, increasing the probability of cancer. Gastrointestinal discomfort Long-term drinking of water with excessive residual chlorine content may also cause gastrointestinal discomfort, such as nausea, vomiting, abdominal distension, diarrhea and other symptoms. In severe cases, it may cause gastrointestinal ulcers, bleeding and other diseases.
In order to reduce the harm of residual chlorine in tap water to the human body, it is recommended to avoid directly using tap water containing residual chlorine as much as possible, boil the water before drinking, and use filtering and purification equipment to reduce the residual chlorine concentration in the water if conditions permit, while maintaining a healthy lifestyle and enhancing the body's immunity.
