The rumor that the faucet contains lead is not a day or two. What is the matter? How much harm does the faucet contain on health? How to buy a healthy faucet?
The faucet will precipitate toxic elemental lead? This is not shocking. On July 14th, the "One-seventh" column of Shanghai TV Station exposed the results of the Shanghai Quality Supervision Department on some of the faucets on the market. The test showed that among the 68 batches of products that were sampled, there were 6 samples. Lead in water soaked out of the standard. When the news came out, it caused a lot of consumers to discuss the quality and safety of the faucet. Does the overnight water in the faucet really cause lead poisoning? How to reduce lead intake and injury? A series of issues have attracted much attention.
Market status: no lead-free faucet
It is well known that lead can damage people's nerves, hematopoiesis and reproductive system, which is more harmful to children, affecting their growth and development and intellectual development, and causing dementia in severe cases.
The reporter visited several building materials stores in Shanghai and found that in addition to not leaking water, rusting, etc., all major faucet brands are now playing "lead-free" cards. However, an agent who asked not to be named told reporters that "lead-free faucets" are not completely lead-free.
According to the agent, the so-called "lead-free" only minimizes the lead content within the national standard. Compared with ordinary faucets, the lead content is greatly reduced, but it is not completely free of lead. This statement was subsequently confirmed by many industry insiders.
It is understood that most of the current faucets are cast in copper alloys. In addition to copper, copper alloys must contain trace amounts of iron, aluminum, lead and other metal elements. In view of the harm of lead to the human body, many big brands are currently developing “lead-free faucetsâ€. However, because “lead-free faucets†have higher requirements on copper composition, process technology and electroplating, they are higher than ordinary copper faucets. A lot, the current popularity is not high.
The interview found that there is lead in stainless steel and may also contain chromium.
In a hardware store, the salesperson recommended a Prometheus faucet to the reporter, saying that the product is made of stainless steel and completely free of lead. However, in this "lead incident" that was soaring, Pule was also found to have problems: hexavalent chromium exceeded the standard. According to the Shanghai Municipal Bureau of Quality Supervision, “Ingestion of hexavalent chromium can cause thickening of the mucous membranes, nausea, vomiting, severe abdominal pain and hepatomegaly, accompanied by symptoms such as shortness of breath, pulse rate, and meat mites. Health. In this spot check, there were 1 batch of unqualified products in the project, which was a serious quality problem.
"Stainless steel does not contain lead. According to the principle, it is far more environmentally friendly than copper, but it can detect chromium. How do we choose?" In the Shanghai Red Star Meikailong Zhenbei store, Ms. Sun, who is choosing the kitchen faucet, is a little swaying.
Reduce the risk of lead and netizens
1. Let go of the overnight water.
For the mixed faucet market, how to choose safe and qualified faucets has become a major problem for consumers. Many manufacturers are working hard to develop low-lead faucets, but because the country's management system for lead in faucets is still not perfect, consumers do not know how to distinguish.
In this regard, the medical expert's suggestion is to "release the overnight water." Indeed, many people in the industry pointed out that "the current method to reduce the lead content of the faucet is to wash lead, but there is no way to eliminate it all. The faucet itself will accumulate a certain amount of water. After a long time, it will absorb heavy metals. Generally speaking, before using the faucet the next day, It is necessary to let the water accumulated in the faucet overnight and then use it."
2. Entrust a third party to test.
After the news of "leaf lead exceeded the standard", the reporter immediately contacted several famous brands. Most of the brands said that they attach great importance to this. They have launched an emergency investigation procedure, conducted source surveys and inspections on related products, and promised to announce the results of the investigations at the first time.
It is understood that the national testing center needs 5 working days for testing. However, in addition to waiting for the merchants to publish the survey results, consumers can call the Shanghai Quality Supervision and Inspection Technology Research Institute if they are not assured of the lead content in the home. The quality hotline 12365 conducts commissioned inspection consultation. At present, the single cost of this test is about 1,000 yuan.
3. Look carefully before buying.
Another expert in the industry suggests that when purchasing a faucet, consumers should also carefully check the quality of the faucet plating. A good electroplating is as bright as a mirror. When you press it on the surface, the traces of the hand will disappear quickly. In addition, consumers are better off selling. The personnel ask for the product test report, brand logo and after-sales service card. If the test report determines that the product is qualified, you can use it with confidence.
