Pollution of the world’s rivers by medicines and pharmaceuticals is becoming a “major threat to the environment and human health.”
This is the conclusion of a study conducted by scientists at York University, which identifies the most problematic residues, which seem to be those of paracetamol, nicotine, caffeine and epilepsy and diabetes drugs.
The biggest pollution turns out to be in the rivers of Pakistan, Bolivia and Ethiopia, but the phenomenon is considered more and more worrying for other regions as well. the cleanest are the rivers in Iceland, Norway and the Amazon area.
Despite research, the extent to which pharmaceutical components have an impact on the environment is not yet fully understood. But the impact they have on fish development and production has already been learned, and scientists fear that increasing the presence of antibiotics in rivers could limit the effect of the drugs.
Samples from 1,000 regions in more than 100 countries were taken to conduct this study. Overall, it turns out that a quarter of the 258 rivers have in their waters “pharmaceutically active ingredients”, at levels that are considered unsafe for aquatic organisms.
The report said that increasing the presence of antibiotics in rivers could lead to the development of resistant bacteria, thus damaging the effect of drugs and threatening global health.
