Last month, the German “Journal of International Health and Environmental Health†reported that researchers from the United Kingdom, Spain, and the Netherlands discovered in long-term experiments that stainless steel faucets formed an environment suitable for the growth of Legionella species after surface aging. It can cause various kinds of veterans’ disease (a typical symptom of pneumonia) and other respiratory diseases. Stainless steel faucets breed more Legionella after surface aging According to reports, the researchers tested the advantages of the three kinds of faucets made of stainless steel, brass and ceramics for the survival of Legionella in three years. The water in the faucet was delivered by metal conduits and plastic guide pipes, respectively. Scientists previously believed that metal conduits will generate rust molecules and thus promote the reproduction of Legionella. This experiment proves that in the third year of using stainless steel faucets, the number of Legionella species in the water will rapidly increase due to aging of stainless steel faucets that can resist corrosion. An average of one-half of all stainless steel faucets breed Legionella (the Netherlands is more typical), while only a quarter of brass and ceramic faucets breed Legionella, and the use of plastic or metal conduit is essentially Does not affect the experimental results. Brass faucet is safe In addition, the study also pointed out that brass faucets are safe. However, in fact, people's demand for brass has gradually declined in recent years. There are two reasons. One is that the high-quality faucets made of brass and bronze are expensive, and the second is that producers have to enter the market to save costs and add silicon to the mixture. This increases the brittleness of the faucet and shortens it. life. Stainless steel faucets are cheaper and less brittle, which is more in line with consumer demand. According to reports, Legionella not only causes Legionnaires' disease, but also causes chronic diseases that are not easily diagnosed. For example, Pontiac fever, which is generally considered to be a common acute respiratory virus infection. <\p><\div>
