Photodemethylation of methylmercury in Eastern Canadian Arctic thaw pond and lake ecosystems
(2016-04-05)
Permafrost thaw ponds of the warming Eastern Canadian Arctic are major landscape constituents and often display high levels of methylmercury (MeHg). We examined photodegradation potentials in high-dissolved organic matter ...
Cooking and co-ingested polyphenols reduce in vitro methylmercury bioaccessibility from fish and may alter exposure in humans
MeHg bioaccessibility is reduced by food preparation
(Elsevier, 2017-10-31)
Fish consumption is a major pathway for mercury exposure in humans. Current guidelines and risk assessments assume that 100% of methylmercury (MeHg) in fish is absorbed by the human body after ingestion. However, a growing ...
