Total mercury and methyl-mercury contents and accumulation in polar microbial mats
Science of The Total Environment, 2015Although polar regions are considered isolated and pristine areas, the organisms that inhabit these zones are exposed to global pollution. Heavy metals, such as mercury, are global pollutants and can reach almost any location on Earth. Mercury may come from natural, volcanic or geological sources, or result from anthropogenic sources, in particular ...

Factors influencing the total mercury and methyl mercury in the hair of the fishermen of Kuwait
Environmental Pollution, 2000Total and methyl mercury (MeHg) levels in the hair of fishermen are described anticipating that they represent the critical group for dietary exposure. One-hundred human hair samples were collected from fishermen (Egyptians: age range 25-60), living in Doha Fishing Village, Kuwait.

Analytica Chimica Acta, 2021
Mercury (Hg) stable isotope signatures are widely used to understand Hg cycling in the environment. Sample preparation methods for determining Hg isotope ratios by CV-MC-ICP-MS vary widely among laboratory facilities and sample types. Here, we present a novel and rapid method for preparing solid samples prior to determining Hg isotope composition.

The analysis of vegetation for total mercury
Water Air & Soil Pollution, 1991Over four hundred vegetation samples were collected for total Hg determination as part of a biogeochemical survey in the Precambrian Shield region near Huntsville, Ontario. An objective of the survey was to obtain accurate data describing the spatial and temporal variation of Hg concentrations in vegetation.

Determination of total mercury in nuts at ultratrace level
Analytica Chimica Acta, 2014Total mercury, at μg kg(-1) level, was determined in different types of nuts (cashew nut, Brazil nuts, almond, pistachio, peanut, walnut) using a direct mercury analyser after previous sample defatting and by cold vapour atomic fluorescence spectrometry.

Total and organic mercury in the pacific blue marlin
Bulletin of Environmental Contamination and Toxicology, 1976Muscle, liver, nerve tissue, and gonads of Pacific Blue Marlin were analyzed for total and organic mercury. The ratios of total to organic mercury in the tissues indicate a partial physiological control over the form in which the mercury exists in the marlin. Total to organic ratios in the muscle, gonad, and central nervous tissue are similar.

Total Mercury in Six Antarctic Notothenioid Fishes
Bulletin of Environmental Contamination and Toxicology, 2015We analyzed white muscle samples from six species of Antarctic fish (suborder Notothenioidei) collected in 2011 from McMurdo Sound, Ross Sea, Antarctica, to assess levels of total mercury (THg). Gymnodraco acuticeps and Trematomus bernacchii exhibited the highest concentrations of THg followed by Trematomus pennellii, Trematomus nicolai, Trematomus ...

A New Method for Total Mercury and Methyl Mercury Analysis in Muscle of Seawater Fish
Bulletin of Environmental Contamination and Toxicology, 2009In this work we have developed a cost-effective method for the analysis of methyl mercury (MeHg) in seawater fish muscle. The novelty of this method lies in the use of microwave-assisted extraction with acidic solution (HCl), addition of toluene, and subsequent extraction with cysteine acetate solution where only MeHg is present because of its affinity

Total mercury, methyl mercury and sulphide in river carron sediments
Marine Pollution Bulletin, 1983Total mercury, methyl mercury and sulphide contents of River Carron sediments (Lothian, Scotland) have been determined. Total mercury concentrations are comparable to other mercury polluted estuaries in the UK, but the methyl mercury values for low-sulphide Carron sediments are generally higher.

Mercury in Mersey estuary sediments, and the analytical procedure for total mercury
Nature, 1976THE Mersey estuary consists of a wide, shallow upper region, separated from the sea by deeper ‘narrows’. The upper estuary (Fig. 1) is an area of continuous accretion of sediment, observed since the mid-nineteenth century with occasional short periods of depletion.
