Biogeochemical Cycling of Methylmercury in Lakes and Tundra Watersheds of Arctic Alaska (original) (raw)
2006, Environmental Science & Technology
AI-generated Abstract
This study investigates the biogeochemical cycling of monomethylmercury (MMHg) in Arctic Alaskan lakes and their surrounding tundra watersheds, focusing on the sources and sinks of MMHg through a mass balance approach. Findings indicate that in situ sediment production is the predominant source of MMHg, whereas photodecomposition serves as the primary sink. An understanding of these processes is essential for evaluating the impacts of climate change on mercury dynamics in vulnerable polar ecosystems.
