In the article published on July 6, the Czech Republic studies concluded that the drug residue from the wastewater pipeline can be addictive in Fish.0: 00/1: 27 narrays HAPPY: CNET , the team observed two groups of 60 brown salmon groups raised in separate tanks for 8 weeks. One of the two aquariums has the concentration of stone drugs often seen in rivers and streams, while the remaining tank does not have Drug residues. In addition to drugs, other living conditions of both environments are identical. Then, researchers turn all the above salmon numbers into a common freshwater tank
. At this moment, the fish are familiar with the drug seemingly lethargic than the other group. This shows that they are worried, or have symptoms of "drug craving". Behavior differences last about 96 hours
Scientists also created a pure water tank and drug water. Fish familiar with addictive substances seem to be attracted to the area with high drug concentrations, regardless of where they are in the tank. According to research, this is a sign that the fish "addicted". Chief of Pavel Horky research team, ecologist at the University of Czech Republican Life University in Prague, told the group's discovery He highlights a good example of "pressure on living species in the urban environment". The wastewater treatment plant cannot eliminate domestic drug residues. The addictive substances that will flow into rivers and streams. Dong Horky notes that the stone drug concentration in the wastewater system is relatively low, but there can still be profound impacts on the surrounding ecosystem.Minh Happy RT, CNN . Dịch vụ:
