Mercury in Selected Fish Species Over Time
نویسندگان
چکیده
We explored the Wisconsin Department of Natural Resources’ (WI DNR) fish contaminant database to determine the availability and utility of historical (1970 2002) Hg records for different species and to identify lakes with historical Hg data. Walleye skin-on fillets were selected for further examination. This project supported processing and characterization of 310 additional walleyes from 36 lakes that were collected over the years 2003 to 2006. With these data, we created a dataset of 3,024 individual walleye records from 421 lakes spanning 1982 to 2005. We evaluated temporal trends over all lakes represented in this dataset using several different mixed effects models. We explored the relationships between Hg concentrations and a suite of lake chemistry, morphometry, and other variables.

Bioaccumulation of mercury in some organs of two fish species from the Sanandaj Gheshlagh Reservoir, Iran
The purpose of this study was to monitor the concentrations of mercury in the edible muscle, gill, liver, and skin of common carp (Cyprinus carpio) and silver carp (Hypophthalmichthys molitrix), in the Sanandaj Gheshlagh Reservoir, Iran. Mercury concentrations were assayed using Shimadzu AA 6600 atomic absorption spectrophotometer, and the results were given as µg/g wet weight. The level of mer...
متن کاملLevels of Mercury in Persian Gulf Frozen Fish Species
Severe discharge of sewage and industrial effluents into the Persian Gulf leads to the deposition of various types of heavy metals, especially lead and mercury, in the muscles of fish. Total mercury and methylmercury contents were determined in the edible parts (muscle tissue, fillet) of two different most popular frozen fish species from the Persian Gulf to ascertain whether the concentrations...

Background and objectives: Methyl mercury can carry out harmful effects on the reproductive, respiratory, and nervous system of human. Moreover, mercury is known as the most toxic heavy metal in nature. Fish and seafood consumption is the major MeHg exposure route for human. The present study tries to cover researches which have been conducted on mercury levels in 21 species of fish from Persia...

In this study, concentrations of mercury (Hg) and 16 other elements as well as methylmercury speciation were quantified in muscle and liver of two commercial fish species. It was also our intention to evaluate potential risks to human health associated with seafood consumption. The fish species, Mullet and Kutum (Caspian White fish) fishes, were obtained from Tonekabon at the Iranian waters of ...

Background and Objective: Mercury (Hg) contamination in marine ecosystems is a major threat to human health in the developing countries like Iran. The main route of mercury exposure is from consumption of fish and seafood. Upon entering mercury in human bodies, Hg is converted into methyl mercury, which may lead to serious implications including neurological disorders, reproductive abnormalitie...
