1. 1. Newly inundated forest landscapes - hotspots for mercury in water and benthic fauna

   University essay from SLU/Dept. of Aquatic Sciences and Assessment

   Author : Kirstine Evald Andersson; [2023]
   Keywords : Wetland restoration; Inundation; Mercury cycling; Beaver impoundments; Aquatic biogeochemis-try;

   Abstract : Mercury (Hg) is a widespread contaminant in high-latitude aquatic ecosystems, where it can undergo microbial transfor-mation into toxic methylmercury (MeHg). Due to its chemical properties, MeHg tends to accumulate in the aquatic food chain and will eventually end up in predatory species at the top of the terrestrial food web. READ MORE
