Ancient Maya mercury use may have come at a severe environmental cost
Ancient Maya populations extensively used liquid mercury and a red mercury-containing pigment known as cinnabar to decorate buildings, pottery, and burial sites. While previous research established local soil and reservoir contamination at certain sites, a recent study published in Science Advances reveals that this heavy pollution spread much further across Maya territory. The widespread use of these mercury substances eventually triggered the collapse of two lake ecosystems, leaving a toxic legacy in Yucatán lake mud and water for centuries.

Ancient Maya Mercury Use Polluted Lakes
Ancient Maya populations extensively used liquid mercury and a red mercury-containing pigment known as cinnabar to decorate buildings, pottery, and burial sites. While previous research established local soil and reservoir contamination at certain sites, a recent study published in Science Advances reveals that this heavy pollution spread much further across Maya territory. The widespread use of these mercury substances eventually triggered the collapse of two lake ecosystems, leaving a toxic legacy in Yucatán lake mud and water for centuries.
Why it matters
This discovery illuminates the severe hidden environmental consequences of ancient human resource utilization. Researchers found that mercury from Maya cities leaked into local lakes at toxic levels over hundreds of years. The findings reveal that cultural practices involving sacred pigments carried a heavy ecological toll.
What is confirmed
- Ancient Maya communities made extensive use of liquid mercury and a red mercury-containing pigment called cinnabar to decorate buildings, pottery and burial sites.
- Mercury pollution from ancient Maya cities leaked into Yucatán lakes at toxic levels for centuries.
- A study published in the journal Science Advances indicates that this pollution spread into wider territory and caused the collapse of two lake ecosystems.
What to watch next
- Further archaeological analyses of additional ancient Maya sites for mercury contamination levels
- Additional peer-reviewed studies examining the ecological and health impacts of ancient heavy metal exposure on Maya populations
