"Black-hearted water" refers to bottled water directly filled by illegal traders with tap water. The polymer in the industrial waste of "black-hearted barrel" will seep out in the water environment, which is an organic pollutant and easy to cause cancer to human body. People who drink "black-hearted bucket" water will not feel it immediately, but like chronic poisoning, the harm will take many years to show up. Drinking these inferior bottled water for a long time will also harm the digestive system and nervous system of the human body, leading to dizziness, stomachache and even cancer.
2. The problem of "stagnant water"
The storage period of bottled water should not exceed 2 days, because drinking aging water will affect your health. It is understood that water is aging rapidly. Water molecules are long-chain structures. If water is not often hit hard, this chain structure will continue to expand and extend, becoming aged water, commonly known as "stagnant water." There are few people in the office, and it takes 7 to 10 days for a bucket of water. This "stagnant water" is very harmful to health! In recent years, the incidence of esophageal cancer and gastric cancer is increasing in many areas, which experts believe is related to drinking "stagnant water" that has been stored for a long time.
The drinking fountain is polluted by bacteria, so the water won't turn on.
The special electrical structure of the water dispenser makes it very easy to be contaminated by bacteria. First of all, the hot temperature of the water dispenser is 86 degrees, and the cold temperature is 5 degrees, which can't kill bacteria at all, but it is very suitable for bacterial reproduction. After a long time, it is difficult to remove bacteria after forming a bacterial membrane, just like forming a bacterial base camp. After passing through such a drinking fountain, the sanitary water carries thousands of bacteria. The hot temperature of the water dispenser is 86 degrees, and the water cannot be boiled, so it is not suitable for making tea.
4, the cost is high
If the enterprises and institutions that use bottled water have 100 employees, the average annual water consumption is about 100 yuan, which is not a small expense.
