[US] Tian net of groundwater containing 68 kinds of antibiotics Author: Tim net water purification Views: 287 Date: 2019-5-8 15:45:55 published recently in the domestic academic journal "Science Bulletin," the article said, surface water contains 68 kinds of antibiotics and high concentrations, there are 90 kinds of additional pharmaceutical ingredient is non-antibiotic detected. Antibiotic concentration of water is much higher than abroad The article done by the East China University, Tsinghua University, Tongji University and research institutions together for a "pharmaceuticals and personal care products ingredients in surface waters in my country.

The article said, has about 68 kinds of antibiotics were detected in surface water environment in China, and was detected in overall levels of antibiotics and detection frequencies are higher, some antibiotics detected in the Pearl River, Huangpu River and other places frequency up to 100, some antibiotics detected at concentrations up to several hundred nanograms per liter, industrialized countries is less than 20 nanograms. The article said, my countrys annual production of about 1300 kinds of chemical raw materials and cosmetics, which antibiotics PPCPs annual output of 3.3 million tons, which may be an important reason for the water environment frequently detected high concentrations of PPCPs antibiotics. my country is one of the worlds most serious abuse of antibiotics, the drug is an antibiotic yield of 70, this ratio is only 30 in Western countries.

And because large-scale farming, in order to prevent illness, to put a lot of antibiotics, it affects the body of water. "He said that excessive intake of antibiotics will certainly affect health, but the waters of antibiotics and hormones in the end to what extent affect human health, the scientific community has not been a clear analysis of the pharmaceutical industry and the aquaculture industry there is a problem of excessive emissions can be said that a large piece of rural pollution caused by farming is now the public have some concerns about the abuse of antibiotics and hormones and other environmental issues. to solve this problem, in addition to good pollution control outside, also should avoid excessive use of antibiotics.
