It placed waterways in Lahore, Bolivia and Ethiopia among the most polluted while rivers in Iceland, Norway and the Amazon rainforest fared the best. The latest study by the University of York on pharmaceutical pollution of the world’s rivers found Lahore’s River Ravi the most polluted in the world posing a ‘threat to environment and human health’. Cumulative pharmaceutical concentrations were calculated at each sampling site as the sum of all API residues quantified at that specific location. The most polluted sampling site was located in the Rio Seke (La Paz, Bolivia) and had a cumulative API concentration of 297 µg/L . Expressing concern over the latest findings about river pollution, environmentalist Afia Salam said the River Ravi had been turned into a drain with human and industrial wastes.
