Global mercury levels in rivers have doubled since Industrial Revolution, research reveals
- Researchers found that mercury levels in global rivers have increased two-to-three-fold since the 1850s due to human activities.
- This rise results from industrial practices like coal combustion, mining, and manufacturing, while regulatory rollbacks threaten further increases.
- Mercury accumulates in Arctic ecosystems through ocean currents, harming wildlife such as polar bears and marine mammals, and affecting Inuit communities reliant on hunting.
- The study reports a 595 megagram yearly mercury increase in rivers since the 1850s and quotes Prof Basu stating, "we can't continue as business as usual."
- The findings imply mercury pollution control is urgent but Arctic mercury levels may take centuries to decline, highlighting the need for strong policies and monitoring.

Since industrialization, mercury has increased considerably in the seas. According to a study, the development has various causes. In a world region, the situation has eased.
Global mercury levels in rivers have doubled since Industrial Revolution, research reveals
Mercury levels in the world's rivers have more than doubled since the pre-industrial era, according to new research from Tulane University that establishes the first known global baseline for riverine mercury pollution.
Groundbreaking research has revealed that human activities have multiplied the levels of mercury circulating in rivers, with serious consequences for the health of the entire planet. The world's rivers today carry more than twice as much mercury as in the pre-industrial era. New research has revealed that rivers have become one of the main pathways for mercury contamination on the planet. According to one study, global river mercury levels have …
Today, rivers transport about two and a half times as much highly toxic mercury into the seas as they were around 1850. This is reported by an international research team based on measurement values and computer models. The main sources of heavy metal are industrial processes, metal mining, small mining in the search for gold and the combustion of coal, according to a group headed by Yanxu Zhang from Tulane University in New Orleans in the journ…
