Mercury and Rice in the California Delta: Lessons Linking Wetlands to Water to Wildlife
- Wetlands are hotspots for mercury methylation and export of methylmercury to aquatic foodwebs.
- Rice is the most abundant wetland type in California and globally in temperate and tropical latitudes.
- Physical, chemical and biological Hg transformations are temporally pulsed in agricultural wetlands, due largely to seasonal water management practices.
- Monitoring methylmercury at the right time and location is essential to managing and projecting future exposure for wildlife and humans.
