New Delhi, Sep 25 (PTI) An estimated 23 million people around the world live on flood-plains contaminated by potentially harmful concentrations of toxic waste from metal-mining activity, according to a study.

The research, published recently in the journal Science, provides new insights into the extensive impact of metal mining contamination on rivers and floodplains across the world.

Using a new georeferenced global database of 185,000 metal mines and employing a combination of process-based modelling and empirical testing, the research assessed the global scale of metal mining contamination in river systems and its repercussions for human populations and livestock.
