Do you know the dangers of "overnight water" in the tap?
For most citizens, the first thing after getting up in the morning is to turn on the tap to wash your face, brush your teeth, and boil water. As everyone knows, just released from the water may be hidden "health killer".
"It's best not to use the 'overnight water' that's stuck in the faucet, but every morning when you turn on the faucet, you can empty it for a while and use it to flush the bathroom, mop the floor, etc. In addition, small accessories in the pipes, such as connecting hoses and spools, are also involved in drinking water safety, so be sure to select qualified products." Chai Chunyan, director of the laboratory of the county water group center, told reporters, "when we take samples of pipe network water, we also have regulations to put them for 5 minutes before sampling, because what stays in the pipe all night is' dead water', which cannot represent pipe network water. Some water pipes in the city have been used for a long time, the degree of oxidation is deep, and the lead content is also a bit high. While we are doing water pipe maintenance and renovation on a regular basis, we will also remind residents not to drink the 'overnight water' stranded in the water pipe '.
It turns out that the tap water in the faucet and water pipe that was out of service overnight is still. The water will react with the metal pipe wall and the metal chamber of the faucet to form metal-contaminated water, and the microorganisms remaining in the tap water will also multiply. The water contains a lot of substances harmful to the human body, and may also hide an acute respiratory infectious bacteria-Legionella that threatens human health. If the use of inferior faucets, "overnight water" in the lead content will be seriously exceeded.
So, how many citizens know the dangers of "overnight water" and will develop the habit of "putting it first and using it later"? The reporter randomly interviewed citizens of different age groups, and the survey found that most people use it directly and do not know the dangers of overnight water, especially the older citizens, who think it is too wasteful to put the water away in vain. In contrast, young mothers with children pay special attention to this aspect. For example, Ms. Xu learned from the media 10 years ago that the high lead content in overnight water may damage the nervous, hematopoietic and reproductive systems, which is more harmful to children and affects their growth and intellectual development. Since then, she has developed the habit of letting go of "overnight water.
The reporter also found in the investigation that although some citizens do not have the habit of "put it first and use it later", they have installed water purifiers for the health of their families. Mr. Wang, who lives in Fengzeyuan, said that his wife is a doctor, and there are too many patients with stones at ordinary times. When decorating her home, her first proposal was to install a water purifier, saying that she could cook rice and cook with the water of the water purifier, and she could rest assured when eating.
The reporter also investigated the water purifiers in the market of our county. In recent years, as people pay more and more attention to the safety of drinking water, the sales volume and style of water purifiers are constantly rising and enriching. According to different water quality, it can be divided into purified water and pure water; according to different functions, the machine has water purifier and pure water; according to different functions, it is also divided into kitchen water purifier, direct drinking machine, water softener, pipeline machine, central water purifier, etc. The variety is dazzling. The role of descaling sterilization, in addition to lead in addition to silver ions, there are softening and inhibiting scale, there is sand and odor... According to different needs, the choice of brands and types are also different. However, it should be noted that no matter what kind of water treatment products are selected, the water purification components need to be replaced regularly, otherwise it may bring secondary pollution.
If you don't have a water purifier installed in your home, you really don't have to worry about the safety of water quality, because the tap water in our county strictly implements the 106 new national standards for water quality testing issued in 2012, and the water quality of the water supply is better than the national standards. In theory, it has reached the standard that can be directly drunk. However, at present, even if the factory water meets the standard requirements, the aging of the pipe network and the non-standard secondary water supply facilities may still affect the user's water use. Therefore, it is very important to develop the habit of "put before use".
