Session ID#: 5828
Session Description:
Our understanding of mercury biogeochemistry has advanced significantly over the past few decades, helping to inform recent global legislation intended to control mercury pollution and reduce ecosystem effects and human exposure. One of the next challenges in mercury biogeosciences research is to be able to better predict and control impacts from environmental change (e.g. global climate change, land-use change due to urbanization or natural resource extraction) on mercury deposition, transport, speciation, and bioaccumulation. This session seeks contributions that highlight recent advances in our understanding of mercury biogeochemistry as it relates to environmental change. Experimental and observational research, long-term datasets, before-after impact studies, and modeling work are especially encouraged, particularly as they relate to changes in mercury methylation/demethylation processes, microbial controls, landscape source/sinks, transport between ecosystems, food web dynamics, and land-atmosphere interactions.
