China's major rivers are contaminated with antibiotics
A recent study conducted by experts from the East China University of Science and Technology, Tongji University and Tsinghua University found that the water of Chinese rivers contains 159 types of medical and cosmetic substances, 68 of them are antibiotics.
According to China Daily, the concentration of antibiotics in some samples was hundreds of nanograms per liter (in developed countries, this figure does not exceed 20 nanograms per liter of water).
“Antibiotics are dangerous for aquatic organisms, but they do not harm people directly. But since the beginning of their use, antibiotics have been present in the environment in large quantities. So many microorganisms have developed resistance to antibiotics, and in case of illness they simply will not work, ”said Zhao Jindong, head of the Institute of Hydrobiology of the Chinese Academy of Sciences. According to him, the main source of antibiotics in natural reservoirs is sewage from residential premises.
Previously, researchers found that China is one of the countries where antibiotics are very widely used, amounting to 70% of the total number of drugs produced.
Fu Tao, director of the Tsinghua University Research Center, said that other sources of antibiotics were drains from pharmaceutical companies and livestock enterprises. “It is possible to purify water, but this requires deep processing of water using ozone and biomembranes. Most of China’s water treatment plants do not have such equipment, ”Fu Tao added.
Perhaps the situation will change the adoption of a new law on environmental protection, which 24 April was transferred to the government of China for consideration.
