TRANSCRIPT
Mercury and Rice in the California Delta
by Lisamarie Windham-Myers, USGS Research Ecologist, National Research Program
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 locationis essential to managing and projecting future exposure for wildlife and humans.
