“…8,9 For the determination of the individual species of arsenic, several combinations of techniques (separation + element-selective detection) have been attempted, but high-performance liquid chromatography (HPLC) in conjunction with ICP-MS or hydride generation atomic uorescence spectrometry (HG-AFS) has emerged as one of the best combinations for monitoring purposes. [1][2][3]6,7,[10][11][12][13][14][15][16][17][18][19][20][21][22][23] Most arsenic analytical techniques require samples to be extracted or digested prior to instrumental analysis. This approach was used consistently in the majority of the literature reviewed when particulate matter was collected on lter media.…”

Inorganic arsenic species in ambient particulate matter (PM 10 and PM 2.5 ) have been determined in an urban area, in the vicinity of a metallurgical industrial plant. The developed high performance liquid chromatography inductively coupled plasma mass spectrometry (HPLC/ICP-MS) method allows monitoring of particulate As(III) and As(V)-species, with a limit of quantification of 0.34 ng m À3 As(III) and 0.23 ng m À3 As(V), respectively. Good agreement was obtained between the sum of the concentrations of As(III) and As(V) determined by HPLC/ICP-MS and the total As concentrations determined by XRF, indicating a complete extraction of the As species. During the measuring campaigns for PM 10 and PM 2.5 , a significant conversion (oxidation) up to 54% of exogenous spiked As(III) was observed. The total amount of the spiked As(III) was well-recovered (PM 10 and PM 2.5 on average 108% and 101%, respectively). The extraction of the filter in combination with the sampled air matrix is likely to induce the As(III) conversion. The average measured As concentration in PM 10 during a 40-day monitoring campaign (30 ng m À3 ) at a hot spot location is above the European target value of 6 ng m À3 . The measured As concentration in PM 2.5 was half the value of the measured concentration in PM 10 and no relative enrichment of total As was observed in either particulate matter fractions. However, in PM 10 , As(V) was the main component, while in PM 2.5 , As(III) was the dominant species. During the monitoring campaign, the fraction of particulate As(III) varied between 19 and 61% in PM 10 and a trend towards a higher fraction of As(III) with increasing concentration of total As was observed. XANES and XRD analyses were used for the identification of arsenic species in local PM sources and confirmed the presence of Ca 3 Sr 2 (AsO 4 ) 2.5 (PO 4 ) 0.5 (OH), As 2 O 3 and As 2 O 5 species.

“…Authors rarely give the value of the obtained LOQ and the manner of its designation. The most commonly employed method is to evaluate LOQ as 3 times the LOD [1]. In some papers, LOQ was calculated as 10 times the LOD, 6 or 10 times the standard deviation of the blank sample [24][25][26].…”

The approach presented in this article refers to the modification of a method for the detection and quantitative determination of chromium species in water by high-performance liquid chromatography inductively coupled plasma mass spectrometry. The main aim of this work was to establish a detailed validation of the analytical procedure and an estimation of the budget of measurement uncertainty which was helpful in recognizing the critical points of the presented method. As a result of the method validation experiment, the obtained limit of quantification, repeatability and intermediate precision were satisfied for the quantification Cr(III) and Cr(VI) in water matrices. The trueness of the method was verified via an estimation of the recovery of the spiked real samples. The recovery rate of both determined analytes was found to be between 93 and 115 %. Considering that the validation of the method and the evaluation of measurement uncertainty are crucial for quantitative analysis, the above-mentioned assessment of the uncertainty budget was performed in two different ways: a modelling approach and a single-laboratory validation approach. The measurement uncertainties of the results were found to be 4.4 and 7.8 % for Cr(III), 4.2 and 7.9 % for Cr(VI) using the classical concept and method validation data, respectively. This paper is the first publication to presenting all the steps needed to evaluate the measurement uncertainty for the speciation analysis of chromium species. In summary, the obtained results demonstrate that the method can be applied effectively for its intended use.

Mercury (Hg), arsenic (As) and selenium (Se) are ubiquitous in the environment and exist in a variety of species, which have great influence on their transport, bioaccumulation and toxicity. This review presents the recent research progress in speciation analysis of Hg, As, and Se, with emphasis on enhanced cold vapor generation as interface for liquid chromatography and atomic spectrometry, speciation of volatile species in gas phase, and isotope dilution technique to improve the precision and accuracy of speciation. Hyphenated techniques to characterize the complexes of Hg and As with phytochelatins and chromatographic separation coupled with multi-collector-inductively coupled plasma mass spectrometry to measure species-specific isotopic ratios, are also briefly discussed. Mercury (Hg) and arsenic (As) are among the most highly toxic elements for humans and ecosystems and can cause serious environmental and human health problems even at low concentrations [1,2]. Selenium (Se) is an "essential toxin" for human health. It has been recognized as an important antioxidant and anti-cancer element. However, Se can also pose negative impact such as defective skin and hair loss [3]. The adsorption/uptake, transport, bioaccumulation, metabolism and toxicity of these elements strongly depend on their chemical species present in environmental and biological samples. In the environment, one species can transform to another through chemical or biological processes. For example, in anaerobic sediments, sulfur-reducing or iron-reducing bacteria can methylate inorganic mercury into highly toxic methylmercury (MeHg) [4,5]. Therefore, speciation analysis of Hg, As and Se is of great importance in order to elucidate the biogeochemcal cycle and toxicology of these elements. Speciation analysis mainly involves chromatographic separation (gas chromatography (GC) or high performance liquid chromatography (HPLC)) hyphenated with element-specific spectrometry or molecular mass spectrometry. This review presents the recent advances in speciation analysis of Hg, As, and Se based on chromatographic separation, with emphasis on enhanced cold vapor generation (CVG) as interface for LC and atomic spectrometry, speciation of volatile Hg, As and Se in gas phase, and isotope dilution technique to improve the precision and accuracy of speciation. Hyphenated techniques to characterize the complexes of Hg and As with phytochelatins and chromatographic separation coupled with multi-collector-inductively coupled plasma mass spectrometry (MC-ICP-MS) to measure species-specific isotopic ratios, are also briefly introduced.
