Mercury (Hg) is a globally-distributed pollutant, toxic to humans and animals. Emissions are particularly high in Asia, and the source of exposure for humans there may also be different from other regions, including rice as well as fish consumption, particularly in contaminated areas. Yet the threats Asian wildlife face in rice-based ecosystems are as yet unclear.

- Anthropogenic mercury (Hg) inputs have surged in the last century, increasing methylmercury (MeHg) levels in aquatic systems, which pose health risks to the environment and humans.
- The common loon (Gavia immer) serves as a bioindicator for assessing the toxic effects of Hg in freshwater, revealing significant adverse impacts on behavior and reproductive success tied to increasing MeHg body burdens over an 18-year study.
- Findings indicate that loons with elevated Hg levels exhibit concerning behaviors and reduced reproductive rates, highlighting the urgent need for standardized monitoring to address mercury contamination impacts on breeding populations and aquatic ecosystems.
