    Mercury monitoring for measuring mercury content in hair

    Measurement of mercury content in hair is a convenient technique to estimate dietary exposure without having to handle tissues or bodily fluids. As the mercury present in hair is comprised of different mercury species, full speciation of the compounds is needed for complete understanding. Environment Canada published a technique where treating a basic digestion with Cd2+ in the presence of cysteine allowed analysis of inorganic mercury and total mercury using a Tekran 2600 System. Methyl mercury was then calculated...

    Mercury monitoring for mercury flux measurement

    The Tekran 2537 has been used in numerous published studies to measure the deposition or evasion of mercury from natural or contaminated surfaces (i.e. flux measurements). It is anticipated that many mercury flux measurements will be needed in the future to assess the impact of climate change on mercury cycling in the environment. There are two basic ways to do mercury flux measurements. First, the dynamic flux chamber method utilizes a custom enclosure, with controlled air flow, to measure the inlet and outlet...

    Mercury monitoring for aircraft research measurement

    An examination of the literature shows that the Tekran 2537 is the choice for measurements of mercury aboard research aircraft. Several research groups in Europe and North America have used the Tekran 2537 on an aircraft platform for point source plume studies, free troposphere speciation characterization, vertical profiles, characterizing emission source regions and even the stratosphere (http://www.caribic-atmospheric.com/instrum/hg.html). Normally, the Tekran 2537 requires simple modifications for aircraft...

  • Determination of the mercury concentration in naphtha

    Introduction The mercury concentration in crude oil and petroleum products can vary in a wide range of less than 0.1 ppb to dozens ppm. Direct mercury determination in crude oil and petroleum products at the range above 5 ppb is covered by ASTM D7622-10(2015) "Standard test method for total mercury in crude oil using combustion and direct cold vapor atomic absorption method with Zeeman background correction". Mercury determination in naphtha and light petroleum products (condensate, gasoline and diesel fuel) at a...

  • Determination of Mercury in Water Samples by HG-AFS

    Mercury and its sompounds are highly toxic materials and can be transferred into the human body via water; the concentration of mercury in water generally is very low. With the superior sensitivity of Aurora`s Atomic Fluorescence Spectrometer, the LUMINA 3300, direct measurement of mercury in water sample is possible.

  • Direct atomic absorption mercury determination in foodstuff and mixed feed

    Direct atomic absorption mercury determination (without any pre-treatment procedures) in food is complicated by its organics matrix. That is the reason why almost all AAS methods of mercury determination in foodstuff include sample digestion by acids.
