Researchers analyzed samples from rivers in 72 countries and found that antibiotics were present in 65% of them.
The world's rivers are widely contaminated with antibiotics, according to a new global study, the first of its kind.
Researchers from the University of York in the UK analyzed samples from rivers in 72 countries and found that antibiotics were present in 65% of them.Dangerous levels of contamination were most frequently found in Asia and Africa, the team said, with sites in Bangladesh, Kenya, Ghana, Pakistan and Nigeria exceeding safe levels by the greatest degree.
To counter that, Boxall said, it will be necessary to invest in infrastructure for waste and wastewater treatment, tighten regulations and clean up already contaminated sites."Solving the problem is going to be a mammoth challenge," he said. The researchers will present their findings at the annual meeting of the Society of Environmental Toxicology and Chemistry in Helsinki on Monday and Tuesday.
