Curbing six key sources could halve pharmaceutical mixture exceedance in global rivers
The Brief · written from 2 sources
- A machine-learning model using 1,017 toxicity assays in three species and 24 geospatial predictors maps toxicity from pharmaceutical mixtures in rivers.
- Pharmaceutical mixture toxicity exceeds ecological thresholds in 13% of global rivers.
- Targeted control of six key pollution sources could substantially reduce these risks, according to the study.
Why it matters
The study points to specific pollution sources whose control could reduce pharmaceutical mixture toxicity in rivers, which can inform where regulators and water managers focus their efforts.
