Biodynamic understanding of mercury accumulation in marine and freshwater fish
Mercury (Hg) is a global environmental pollutant that has been the cause of many public concerns. One particular concern about Hg in aquatic systems is its trophic transfer and biomagnification in food chains. For example, the Hg concentration increases with the increase of food chain level. Fish at the top of food chain can accumulate high concentrations of Hg (especially the toxic form, methy...
متن کاملAssessment of Mercury Accumulation and Magnification in a Freshwater Food Chain: Sediment, Benthos and Benthivorous Fish
Background: Present study was conducted to measure the level of total mercury (tHg) in sediments, benthos and benthivorous fish (i.e., common carp) for determining Biota (Benthos)-Sediment Accumulation Factor (BSAF), as well as Biomagnification Factor (BMF) of tHg between two trophic levels of benthos and benthivorous fish caught from Sanandaj Gheshlagh Reservoir (SGR) in the west of Iran. Met...
متن کاملHistamine Level in Freshwater and Marine Fish Sold in Bulgarian Markets
Background: Histamine is an essential biogenic amine produced as a result of microbial decomposition of histidine during seafood processing and storage. The objective of this study was to evaluate histamine concentration in freshwater and marine fish marketed in Stara Zagora region, Bulgaria. Methods: Forty fish samples were purchased from local fish farms and retail stores in Stara Zagora, Bu...
متن کاملAutofluorescence in the oocysts of marine and freshwater fish coccidia.
Autofluorescence has been reported as a method for detecting oocysts of Cyclospora cayetanensis in patients with seasonal diarrhoea (Berlin O.G.W., Peter J.B., Gagne C., Conteas C.N., Ash L.R. 1998: Emerg. Inf. Dis. 4: 127-128), although the same technique had been used earlier, for probably the same parasite, in human subjects with prolonged diarrhoea (Long E.G., White E.H., Carmichael W.W., Q...
متن کاملMethylmercury in freshwater fish linked to atmospheric mercury deposition.
A connection between accumulation of methylmercury (MeHg) in wild fish populations and atmospheric mercury deposition has not been made. Large databases for both MeHg in fish and atmospheric mercury deposition have been assimilated from monitoring efforts spanning the contiguous United States. Here, we compare results of these data sets and show that state-wide average concentrations of MeHg in...
