The Maya's Love of Red Paint May Have Had a Deadly Consequence Nobody Knew About

Key Points:
- A new study of sediment cores from lakes in Mexico’s Yucatán Peninsula reveals severe mercury pollution linked to ancient Maya use of the red pigment cinnabar, with concentrations reaching levels harmful to aquatic life for centuries.
- Mercury contamination coincided with declines in microorganisms, tiny shelled animals, and changes in aquatic food webs, suggesting ecological disruption likely caused by mercury washing into lakes from Maya activities.
- The research highlights parallels with ancient European use of cinnabar and other toxic red pigments, which also exposed populations to mercury and lead poisoning.
- While mercury pollution may have added environmental stress during the Classic Maya collapse (A.D. 750–900), it is not considered a direct cause but rather one of multiple factors including drought, warfare, and political instability.
- These findings underscore how a pigment valued for its cultural and spiritual significance may have inadvertently caused long-term ecological harm and health risks for Maya communities.
