it is reported that in the recent inspection of 11 categories of commonly used materials for interior decoration, such as waterproof coatings and pipes, China's industrial and commercial departments found a total of 84 unqualified products, of which nearly half were faucet products, and 38 were unqualified. Almost all of these 38 products have many problems, ranging from the corrosion resistance not meeting the requirements to the lead and chromium content exceeding the limit specified in the national mandatory standards

Zhang Jing, the person in charge of Jiangnan hardware, told reporters that at present, most of the materials used by manufacturing enterprises for faucets in contact with water are cast copper alloy, anti dezincification copper, stainless steel, etc. in these materials, lead, cadmium, chromium and arsenic, which are more harmful to human body, will be contained in varying degrees. The harm to human body is actually caused by these common toxic pollutants. Among them, excessive lead will damage the nervous, hematopoietic and reproductive systems, especially for children, which can affect children's growth and intellectual development. Long term skin contact with chromium compounds can cause contact dermatitis or eczema. In addition, heavy metals can interact strongly with proteins and enzymes in the human body, making them inactive, and may also accumulate in some organs of the human body, causing chronic poisoning

it is reported that the Ministry of environmental protection of the people's Republic of China also released the national environmental protection standard for faucets (i.e. faucets) this year. This standard pays great attention to human health, and sets strict limits for heavy metals, benzene, formaldehyde and other harmful substances. In terms of protecting human health, the limit values of heavy metal precipitation in the part of faucet in contact with water are: lead ≤ 5 micrograms/liter, chromium ≤ 10 micrograms/liter, cadmium ≤ 0.5 micrograms/liter, arsenic ≤ 1.0 micrograms/liter

■ don't let the price "cover your eyes"

thrift is a traditional virtue of the Chinese nation, and economy is what people pursue in home decoration, but when choosing these materials related to people's health, quality, safety and rest assured is the key

Zhang Jing of Jiangnan hardware said that taking the water outlet of the faucet as an example, iron is only a few yuan, and copper is dozens of yuan. Although these seemingly cheap accessories have saved some money for decoration, once there is a quality problem, the harm to people's lives is very serious. Heavy metal poisoning will solidify the protein in the body. If it is only slightly poisoned, you need to drink a lot of milk. The protein in milk will react with heavy metals, so that people's physical functions will not be damaged temporarily, but you need to go to the hospital immediately after drinking. "The appearance of new faucets looks very bright, and it is generally difficult for ordinary consumers to identify their advantages and disadvantages. In order to pursue low prices, some consumers choose some faucets with inferior quality, which will bring great hidden dangers to people's water safety. Therefore, when choosing faucets, consumers must not choose products only based on price." Said Miss He, the person in charge of a bathroom brand

■ there are three steps to choose faucets

in addition to choosing regular stores and well-known brands, some buying tips are also worth learning. Generally, you can choose in three steps

look: the relevant person in charge of Jiangnan hardware said that the valve bodies of regular brand faucets are cast from brass, and after grinding and polishing, the surface is nickel plated and chrome treated. The coating of regular products has specific process requirements, and has passed the neutral salt spray test, and there is no corrosion within the specified time limit. In addition, consumers can disassemble the faucet and observe its internal structure and interface. If it is made of copper, it is yellow with obvious grinding marks, while zinc alloy will not have such a phenomenon

listen: "the easiest way to identify the quality of the faucet is to weigh it with your hand." Zhang Jing said that good faucets are made of copper and cast with processed and refined brass, while general faucets are mostly made of alloy, and even some faucets are molded with engineering plastics. The easiest way to identify them is to tap gently with your hand, and the plastic faucet cannot make a metallic sound

ask: when buying faucets, it is also indispensable to have a full understanding and detailed inquiry in the early stage. The seemingly simple faucet actually has many problems. It is the best policy to make a decision after having a certain understanding of it
