“…The selection of the material of the filters is an important matter, because in most cases the filter has to be acid digested or extracted with a suitable solution for posterior analysis of As present in the PM. Most of the studies employ quartz fibre filters, following the method of the European norm EN 12341 for PM10 gravimetric determination [48,49,[55][56][57][58][59]. A previous European norm (EN 14907) allowed the use of other types of materials in addition to quartz for PM2.5 determination [52].…”

This review describes the different steps involved in the determination of arsenic in air, considering the particulate matter (PM) and the gaseous phase. The review focuses on sampling, sample preparation and instrumental analytical techniques for both total arsenic determination and speciation analysis. The origin, concentration and legislation concerning arsenic in ambient air are also considered. The review intends to describe the procedures for sample collection of total suspended particles (TSP) or particles with a certain diameter expressed in microns (e.g. PM10 and PM2.5), or the collection of the gaseous phase containing gaseous arsenic species. Sample digestion of the collecting media for PM is

“…According to the literature, the highest levels worldwide were 5.4-8.2 ng/m 3 in an industrial area close to steel mills in Isfahan, Iran (Talebi, 2003). Richter et al (2007) reported a Cr(VI) concentration of 5.0 ng/m 3 in Santiago, Chile, which is also considerably higher than the concentrations in Korea.…”

This paper reports the results of a field evaluation which used sampling and analytical methods to det ermine the levels of airborne hexavalent chromium Cr(VI) in major industrial complexes in Korea over a seven year period (20072013). Cr(VI) concentra tions were determined using cellulose filter sampling and ion chromatography analysis. In order to vali date the analytical performance of these methods, studies were also carried out to investigate data quality control (QC) parameters, such as the method detection limit (MDL), repeatability, and recovery efficiencies. The average concentrations of Cr(VI) for the nine industrial complexes in Korea were in the range of 0.09 to 1.40 ng/m 3 , which is similar to of the concentrations in other industrial areas around the world. The impacts of Cr(VI) emissions from industrial areas on Cr(VI) concentrations in neigh boringresidential areas were considerably low, and the dispersion of Cr(VI) from industrial areas to res idential areas was estimated to be 'notsignificant'. Cr(VI) levels were not affected by seasonal varia tion, which suggests that chromium was emitted continuously from the industrial sources throughout the year. The concentration of Cr(VI) measured accounted for 0.7 to 9.4 percent of the total chromi um level, which is a low percentage compared to those in other urban areas around the world. This is the first report in an international journal of a field study conducted in Korea to determine the concen tration of Cr(VI) in the ambient air of industrial and residential areas.

“…For every fraction, the As, Cd, Co, Cr, Hg, Mn, Ni, Pb, Sb and Se content was determined. The total content of each trace element was calculated as the sum of the four extraction steps [18,21]. Determining the concentration of the various trace elements for each sample was carried out by inductively coupled plasma mass spectrometry (ICP-MS) (NexION 300D, PerkinElmer, Inc., Waltham, MA, USA).…”

Abstract. The analysis reported in this study was performed to characterize the concentrations and water-soluble content of trace elements (As, Cd, Co, Cr, Hg, Mn, Ni, Pb, Sb and Se) in PM2.5, PM10 and PM2.5-10 samples collected in the surroundings of power plants in southern Poland. The solubility of trace elements bound to PM2.5 and PM10 was higher than for PM2.5-10, and in most cases, significant differences were revealed in the relative percentage concentrations of the water-soluble fractions. The occurrence of Cd, Cr, Mn, Ni, Pb and Se in first PCA (Principal Component Analysis) factor (PC1) − indicate coal combustion processes as the potential source of these elements. Other factors indicate two further anthropogenic sources: the resuspension of road dust due to vehicular activities and waste burning in domestic sources − factor (PC2), and, soil dust sources affected by fugitive dust from the mining processes and unpaved roads, as well as transportation and deposition of coal −factor (PC3).
