Total gaseous mercury in Québec (Canada) in 1998
Science of The Total Environment, 2000The main objectives of this paper were to report total gaseous mercury (TGM) concentrations at four stations along the St. Lawrence River in 1998 and to give some insights regarding their fate. The TGM network stretches from latitudes 45 degrees N to 50 degrees N. TGM and ozone concentrations (used as complementary pollutant) were presented. The median

Total mercury and mercury species in birds and fish in an aquatic ecosystem in the Czech Republic
Environmental Pollution, 2007Total mercury and mercury species (methylmercury-MeHg, inorganic mercury--Hg(2+)) were determined in the aquatic ecosystem Záhlinice (Czech Republic). Four tissues (muscle, intestines, liver and kidney) of three bird species--cormorant, great crested grebe and Eurasian buzzard, muscle tissues of common carp, grass carp, northern pike, goldfish, common ...

Is total mercury concentration a good predictor of methyl mercury concentration in aquatic systems?
Water, Air, & Soil Pollution, 1995Methyl mercury (MeHg) concentrations were compared to total mercury (THg) concentrations in a variety of types of aqueous samples collected at the Experimental Lakes Area during 1991 through 1993. In several streams, an experimentally flooded wetland, and peat pore water, there was no relationship between MeHg and THg concentrations. %MeHg (compared to

Determination of total mercury in fish: an improved method
The Analyst, 1983A simple method is described for the rapid digestion of fish for total mercury determination by cold-vapour atomic-absorption spectrophotometry at 253.7 nm. A significant departure from previous methods is the use of concentrated hydrochloric acid together with sulphuric and nitric acids in the open digestion of samples.

Determination of Total Mercury in Soils and Sediments
Journal of Environmental Quality, 1975AbstractA simple one‐step digestion procedure was evaluated for extracting total mercury from soils and sediments. The procedure evaluated involves digesting soil or sediment samples with concentrated HNO3 and 4N K2Cr2O7 (2:1, vol/vol) for 4 hours at 55C and analyzing mercury in the extract by flameless atomic absorption. Recovery of total mercury from

[Total and methyl mercury contents in arthropods].
Huan jing ke xue= Huanjing kexue, 2008We researched mercury contents in plants and arthropods collected from the river banks in mercury polluted areas. The results show that total mercury (T-Hg) and methyl mercury (Me-Hg) in Locusta migratoria manilensis and Acrida chinensis are 0.032 - 0.402 mg x kg(-1), 0.023 - 0.362 mg x kg(-1) and 0.003 - 0.031 mg x kg(-1), 0.004 - 0.015 mg x kg(-1 ...
