A study done from University of York that analysed rivers from 72 countries found that 65% of them had significant traces of antibiotics. Multiple rivers across Asia and Africa had dangerous concentrations that exceeded safe levels and the drug Metronidazole was found exceeding safe levels by up to 300 times in Bangladesh. Most of the worst rivers were next to wastewater treatment plants and waste or sewage dumps in emerging economies but traces of antibiotics found across the Americas and Europe show this is a “global problem”.
