Strictly control the spread of major pollution routes, which is a problem we must pay attention to! Among them, the disinfection of water quality is necessary, but after the water has been chlorinated for a period of time, some effective chlorine will be left in the water, which is “residual chlorine”. This total residual chlorine test is also critical. So what is the purpose of testing the chlorine residual index in water? This chapter water quality online monitoring instrument manufacturers to understand the relevant issues together with you!
In 2003, China’s environmental departments have taken the residual chlorine as a reference index for the standard management of pollutant discharge fees. Although residual chlorine is not a single detection parameter, it is indeed an indispensable detection index. Why is that? In fact, it is very simple, once the excess chlorine water is discharged, human drinking contact will cause harm to the human body.
The Specific Injuries are asFollows
· Can stimulate the eyes, nose, throat above the respiratory tract, causing acute pulmonary edema, high concentration can paralyze the nerve in the respiratory area. Long-term inhalation of low concentrations of chlorine can cause chronic poisoning. When chlorine is added to water, it will cause your skin to bleach, peel off skin layers and cause allergies. When heated, chlorine produces carcinogens such as trichloromethane.
· The influence of tap water containing residual chlorine on washing vegetables and fruits.
Chlorine will destroy nutrients such as vitamins and other substances in vegetables, fruits and grains, seriously affecting the absorption of nutrients in the human body.
· What should I do if I take a bath with water exceeding the chlorine limit?
Forty percent of the total amount of chlorine in the bathroom is inhaled through the respiratory tract, and three layers are absorbed by the skin, which is 6 to 8 times the amount of chlorine that enters the human body through drinking, causing itching in light cases, and increasing the risk of cancer by 30% in heavy cases.
It can be seen that it is necessary to use RCl900 total residual chlorine online analyzer to monitor residual chlorine in water! It is an important link to ensure the safety of water quality!
