Abstract. The monitoring of low gaseous elemental mercury (GEM) concentrations in the atmosphere requires continuous high-resolution measurements and corresponding calibration capabilities. Currently, for GEM is still an issue at ambient (1–2 ng m−3). This paper presents a flow GEM, traceable to NIST 3133 Standard Reference Material (SRM). approach was tested using direct analyser based on atomic absorption spectrometry with Zeeman background correction (Zeeman AAS). produced standard...
Abstract Hg isotope analysis in samples from background regions is constrained by the presence of low concentration and therefore requires a pre-concentration method. Existing methods are long sample processing time limited loading capacity. Using foliar as test case, an optimized method presented that involves microwave-assisted digestion for with addition pre-digestion step. Microwave-digested CRMs were transferred to impinger, reduced SnCl 2 , collected 2.25 mL concentrated inverse aqua...
The current speciation methods for mercury (Hg) measurements are fraught with considerable uncertainty, from sample collection to calibration. High reactivity of gaseous oxidized Hg (GOM) species and their ultra-trace level presence makes them difficult calibrate. Given that improper calibration may lead measurement biases, reliable metrologically traceable required accurately quantifying GOM in air. In the present study, we applied recently developed method based on non-thermal plasma...

Using foliar as test case, an optimized method presented that involves microwave-assisted digestion for with addition pre-digestion step. Microwave-digested NIST SRMs were transferred to impinger, reduced SnCl2 collected 2.25 mL concentrated inverse aqua regia (3:1 v/v). This resulted optimal acid solution ideal on MC-ICP-MS. The time...

<p>Several approaches exist in literature for sample collection, preparation, and quantification of mercury concentration foliage samples. Comparability results from studies with varying methodological are therefore critical accurate estimation vegetation control on Hg intercompartmental exchanges. To this end, field visits were carried out the collection foliar samples <em>Carpinus betulus</em> two forest sites Slovenia having contrasting source...
