Environmental pollution is increasingly alarming. The latest study found that rivers throughout the world were contaminated with antibiotics with levels exceeding the threshold.
Reported by AFP, the scientists found one or more antibiotics in two-thirds of 711 samples taken from a number of rivers in 72 countries. In dozens of locations, antibiotic concentrations exceed the level of safety set by the AMR Industry Alliance, a group of pharmaceutical companies.
Countries with the highest levels of river pollution involving antibiotics include Bangladesh, Kenya, Ghana, Pakistan and Nigeria. In Bangladesh, the concentration of the antibiotic Metronidazole was found 300 times above the threshold.
While in Europe, one of the important sites in Austria has the largest concentration of antibiotics on the Blue Continent.
“The results are quite eye-opening and worrying, showing severe contamination of rivers throughout the world,” said Alistair Boxall, a scientist at the New York Environment Sustainability Institute.
This study complements the information gap from previous research by completing data from a number of countries that have not been monitored.
Previously, the study said, rivers throughout the world were filled with all types of over-the-counter drugs as well as prescriptions.
Looking at the current trend, the number of pharmaceutical waste entering the water channel is estimated to increase two-thirds before the middle of the century.
Antibiotic contamination not only affects wildlife, but also contributes to the problem of antibiotic resistance.
The World Health Organization (WHO) has warned that antibiotic resistance is becoming a major problem nowadays. WHO called on industry and government to immediately develop new generation drugs.
Taking drugs too often is one of the main causes of antibiotic resistance.
