According to scientific studies, residual chlorine in water is one of the causes leading to a number of diseases such as asthma, liver dysfunction, and more dangerously weakening immunity.
Does tap water have chlorine? Yes, because chlorine is a disinfectant used in water supply systems in many countries around the world, including Vietnam. There is no denying the benefits that this chlorine brings. Using chlorine to disinfect is both cost-effective and effective. Leaving a residual chlorine residue after disinfection helps prevent re-infection of bacteria during distribution, transportation and storage of water at home. However, if the chlorine residue in the water is high, exceeding 0.5mg/l will cause harm to human health. If you smell it, the water has a chlorine smell due to the high concentration of chlorine.
