1. Newly inundated forest landscapes - hotspots for mercury in water and benthic fauna
Master-uppsats, SLU/Dept. of Aquatic Sciences and AssessmentSammanfattning : 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. LÄS MER
2. Catchment influences on mercury methylation in a peatland chronosequence
Master-uppsats, SLU/Dept. of Aquatic Sciences and AssessmentSammanfattning : Since the beginning of industrialization, emissions of mercury (Hg) from human activities in excess of natural levels have increased depo-sition rates to ecosystems, storage in soils and loading to aquatic envi-ronments. Toxicity to animals, subject to this accumulation, as well as to humans consuming them, are the major concerns driving research on this subject. LÄS MER
