The approach for the determination of mercury used at the U.S. Geological SRM’s for Fish Tissue, Hg (ppm) • NRC Can DOLT 2 (dog fish liver) ± Cited by: 1. Appropriate concentrations of mercury standards were added to make the desired calibration curves. Likewise, appropriate amounts of sample extracts were used. In this work, 20 (tuna fish), (oyster tissue), and µL (estuarine sediment) of the sample extracts were added, to account for the mercury concentrations in each sample.

Direct Hg analyzers, which use thermal decomposition and atomic absorption spectrometry, have recently gained popularity for determining organic Hg after procedural solvent extraction from some environmental media, although quantitative recovery from lipid‐rich materials, such as fish Cited by: Determination of mercury speciation in fish tissue with a direct mercury analyzer.
Abstract An acid digestion method followed by cold vapor atomic absorption spectrophotometry for the determination of mercury in fish is described. Sample portions are weighed into partial reflux tubes and digested with a H2SO4/HNO3 mixture. Hydrogen peroxide is added to facilitate complete destruction of organic matter.

The method described in this paper for the determination of mercury in fish provides a rapid, sensitive and accurate system that can be used for routine analysis of fish.
It facilitates the relatively rapid (30–60 min) wet oxidation of samples (–1 g). In addition, few Cited by: The combination of copper nitrate as a chemical modifier and tungsten carbide as a permanent modifier thermally stabilized the mercury up to the atomization temperature of °C, enabling the determination of mercury concentrations in ppb.
Therefore, the proposed method can be used to monitor the levels of mercury in fish muscle tissue by: Determination of mercury in fish. Analytical Chemistry48 (6), DOI: /aca W.

A simple and rapid procedure for measuring total mercury in fish tissues is evaluated and compared with conventional techniques. Using an automated instrument incorporating combustion, preconcentration by amalgamation with gold, and atomic absorption spectrometry (AAS), milligram quantities of wet fish tissue were analyzed directly for mercury (i.e., without acid digestion).
Throughout the world, elevated levels of mercury in fish and shellfish has been a well-documented environmental problem for many years.
The process of mercury accumulation in marine animal tissue begins with natural and anthropogenic sources of mercury in the bodies of water in which the animals inhabit. Microorganisms that form the. 2. SUMMARY OF METHOD 2,1 A weighed portion of the tissue sample is digested with sulfuric and nitric acid at 58°C followed by overnight oxidation with potassium permanganate and potassium persulfate at room temperature.
Mercury in the digested sample is reduced with stannous chloride to elemental mercury and measured by the conventional cold vapor atomic absorption technique.Conference: Determination of total mercury in fish tissue using flow injection atomic absorption Title: Determination of total mercury in fish tissue using flow .Determination of total mercury in fish tissues using combustion atomic absorption spectrometry with gold amalgamation.
