Some of the world’s best-known rivers, including the Nairobi River, are contaminated with antibiotics that exceed levels considered to be safe in health terms.
According to a global study conducted by York University researchers, concentrations of antibiotics found in some of the world's rivers exceed “safe” levels by up to 300 times. Sites, where antibiotics exceeded these levels by the greatest degree, were in Bangladesh, Kenya, Ghana, Pakistan, and Nigeria.
