Every pure copper faucet contains lead. Of course, regardless of the dose and toxicity, it is the water flow network. As long as the lead content is controlled within the scope of national control, it will not have any effect on the body. What happens if the lead content exceeds the standard? Excessive lead content, especially for children, is more harmful than adults. Children's absorption of lead is six times that of adults, and only one-thirtieth of adults' emissions. The main effects are stunted development, learning difficulties, and strange behavior. country's absorption of lead in faucets is no more than five micrograms per liter, which means that one liter of water is released, and the lead content here cannot exceed one 200,000th of a gram. This shows the power of this heavy metal. CCTV has done a test and collected 16 brands of faucets on the market, eight domestic and eight imported. Our domestic brands are very competitive, both in terms of price and the amount of absorption signed, they are more than these foreign imported brands. First of all, a qualified copper faucet, its cost will not be less than 100 yuan, below this price is most likely to be made of recycling barrels. Why add lead to this recycling bucket? It is because it is easy to cut and reduce costs. The terrible thing is that if you buy these inferior faucets, even if your body drinks out of the problem, most people will not think about it. Second, try to buy brand goods, especially domestic goods, do not buy those miscellaneous brands. Third ah, don't believe what lead-free faucet, it is through the process of washing lead, the surface of the thousand washed off. As long as it is copper for a long time, there will be migration out, just to sell more expensive. Finally, the drinking water faucet is best replaced by stainless steel, of course, it must be reliable stainless steel.
