Recently, a shocking incident involving "lead-exceeding" faucets has sparked widespread public concern. A sample test conducted by Shanghai TV Station revealed that out of 13 faucet models tested, 9 had lead levels in soaked water that exceeded national standards. Some products had lead content up to 18 times higher than allowed, while one brand recorded a staggering 173 micrograms per liter—over 34 times the limit. This alarming finding highlights a serious issue in the plumbing industry.
Although faucets may seem like small household items, they play a critical role in ensuring the safety of drinking water and protecting public health. According to investigations, most faucets on the domestic market are made from copper or alloy materials. However, some unscrupulous manufacturers use low-quality leaded brass to cut costs. During surface treatments like electroplating, excessive amounts of lead and chromium are often used, and many companies skip the crucial lead-washing process before shipping. As a result, these faucets can leach harmful lead into the water over time, posing long-term risks to health.
Lead poisoning is no less dangerous than the melamine scandal. Recent quality inspections by the Shanghai Bureau of Quality Supervision found that 21 out of 68 faucet batches failed, with six of them having dangerously high lead levels. Similarly, a Beijing Consumers Association test on 50 ceramic-seal faucets showed that 34% didn't meet safety standards. Only two samples were completely free of lead, underscoring the severity of the problem.
Experts warn that lead exposure can harm the nervous system, immune function, and overall well-being. Long-term use of faulty faucets may lead to kidney stones, developmental issues, and even lead poisoning, especially for children and pregnant women. Some specialists compare the risks of substandard faucets to those of melamine, emphasizing the urgent need for stricter regulations.
Children are particularly vulnerable. Li Zengqi, vice president of the China Lead Element Research Institute, stated that lead poisoning is the number one health threat to children in China. Studies show that 30–40% of urban children have elevated blood lead levels, with major cities reporting rates above 60%. In some cases, children's blood lead levels exceed 100 micrograms per deciliter, a level that can cause severe neurological damage.
The problem stems from poor-quality leaded brass used in many faucets. According to experts at the National Building Materials Hardware Plumbing Product Quality Supervision Center, lead reacts easily with air and water, especially when left standing overnight. To reduce risk, it's advisable to flush the tap for 1–2 minutes before using it after a long period of inactivity. The initial water is often rich in lead, but the second flow is usually safer.
Industry insiders reveal that many faucets labeled as "full copper" are actually made from recycled leaded brass. These products are often reprocessed with added lead and zinc, then sold as "pure copper." A genuine copper faucet typically costs over 100 yuan, while cheaper options are likely to contain more lead. The lower the price, the higher the risk.
Lead-free technology is becoming a key trend in the plumbing industry. Products such as lead-free copper, stainless steel, and composite materials are now available. Some reports suggest that the recent lead contamination incidents may have been linked to the push for stainless steel alternatives.
How can consumers choose a safe faucet? Experts recommend buying from reputable retailers and choosing well-known brands. Always ask for product testing reports, certifications, and after-sales service information. Look for internationally recognized certifications like NSF or CSA. These ensure that the product meets strict safety standards.
To assess a faucet’s quality, you can visually inspect the plating under good lighting. High-quality electroplating should be smooth, bright, and free of scratches. Pressing the surface should leave no visible marks. You can also feel the weight; a solid, heavy faucet is usually better made. Cheaper models may be heavier due to added metal or thick walls.
Testing the faucet’s performance is also important. The valve core is the heart of the faucet. A smooth, easy-to-turn handle indicates good quality. A well-designed faucet should mix air and water effectively, producing soft, quiet water flow.
China is currently updating its national standards for faucets. While existing standards like GB18145-2003 and QB1334-2004 focus on appearance and performance, they lack specific limits on harmful substances like lead. Newer recommendations, such as JC/T 1043-2007, set a lead limit of 0.011 mg/L, but enforcement remains inconsistent.
Internationally, lead limits are strictly regulated. China’s upcoming mandatory national standard will align with U.S. requirements, limiting lead to no more than 5 micrograms per liter. This change is expected to significantly improve the safety of plumbing products in the country.Wpc Louvers Board Wall Panel,Modern Wpc Louvers Type Wall Cladding,Louver Wpc Wall Panel Board,Louver Decorative Composite Board Wpc Wall
