Dangerous levels of antibiotics were discovered in hundreds of rivers in seventy-two countries across six continents.
This, according to the first study of its kind on the subject from researchers at the University of York in the United Kingdom.
They took a closer look at frozen water samples from the rivers and discovered that sixty-five percent of tested sites – presented dangerously high level of commonly used antibiotics.
At one location in Bangladesh – antibiotic levels at one river exceeded safe levels by nearly three-hundred percent.
The study also revealed that these rivers were typically located near sewage sites and treatment plants.
Among the locations that were sampled included England’s Thames River and the Danube, Europe’s second-largest river.
