- The study has estimated the scale of global river contamination from human antibiotic use.
- From 2012-2015, people consumed about 29,200 metric tons of the 40 most-used antibiotics each year.
- Nearly a third of those antibiotics, about 8,500 metric tons, were released into rivers globally.
- Amoxicillin, the world's most-used antibiotic, is the most likely to be present at risky levels, especially in Southeast Asia.
- Antibiotics are critical for treating various bacterial infections.
- They are widely consumed by people, livestock and aquaculture fish, but the drugs are only partially absorbed by the body.
- Much is excreted, entering the environment, especially water bodies.
