“…The extraction efficiency was found to be ca. 92%, a little better than the 86% reported by Oliveira et al [123] when using H 3 PO 4 assisted by microwave radiation. Tsopelas et al [128] procedures.…”

“…The limits of detections provided by other authors for methylated As species (e.g. DMA and MMA) lie between 0.3-0.4 ng m -3 with HG-ICP-OES detection [128], and 1.16-1.97 ng m -3 with AFS detection [123], more than an order of magnitude than those reported by [74]. Therefore, their LODs do not allow them to detect organic arsenic species at the pg m -3 level.…”

“…This involves always an extraction process that has to fulfil some basic premises, as providing a quantitative extraction without altering the distribution of the species using an extraction media compatible with the posterior analysis. Šlejkovec et al [123] sampled coarse (PM2-10) and fine (PM2) particles in filters at urban sites of Budapest (Hungary), using water or 0.1 M phosphate solutions as extractant and sonication during 3 h.…”

“…These authors did not reported methylated species in coarse or fine particles of PM samples. Likewise, Šlejkovec et al [123] employed a two steps extraction procedure for coarse (PM2-10) and fine (PM2) particle, with water and a phosphate solution (pH 6). In this case, only As(V) was found in the samples.…”

“…The initial study of Šlejkovec et al [123] employed an anion exchange guard column for the separation of As(III), DMA, MMA and As(V) in PM extracts of samples from Budapest, using a potassium phosphate solution (pH 6) as mobile phase. After HG with HCl and NaBH 4 solutions, the arsines were transported to a glass gas-liquid separator and an Ar flow transported them to the H 2 diffusion flame of an AFS detector.…”

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

A rapid and simple method has been developed for determination of inorganic elements in airborne particulate matter (PM10) by using acidified subcritical water and ICP-OES. Elements such as Al, As, B, Ba, Cd, Cu, Fe, Mn, Pb, Se, and Zn were rapidly and efficiently extracted from PM10 samples with a solution of 0.1 mol L(-1) HNO(3) under subcritical conditions. The method requires approximately 5% of the amount of acid used in the standard microwave extraction procedure. The material selected for the subcritical extraction manifold was poly ether ether ketone (PEEK), to avoid sample contamination with elements present in previously reported stainless-steel manifolds. The extraction temperature, time of static and dynamic extraction, and flow rate of acidified water were studied keeping the pressure controlled at about 1,500 psig. The efficiency of extraction of most of the analytes increased with temperature, tending to quantitative extraction at temperatures near 150 degrees C. After the extraction process the analytes were determined directly in the extract by ICP-OES. When the method was compared with the USEPA counterpart, the results indicate that under optimized conditions (static extraction time: 15 min, dynamic extraction time: 30 min, flow rate: 2 mL min(-1)) the analytes were extracted with recoveries between 73 and 158%. Alternatively, by using an extraction time of 15 min, the method could be used to screen for all the elements, with recoveries over 50%. The developed method was applied to the determination of inorganic elements in airborne particulate matter in the atmosphere of Santiago, Chile.

This review surveys schemes used to sequentially chemically fractionate metals and metalloids present in airborne particulate matter. It focuses mainly on sequential chemical fractionation schemes published over the last 15 years. These schemes have been classified into five main categories: (1) based on Tessier's procedure, (2) based on Chester's procedure, (3) based on Zatka's procedure, (4) based on BCR procedure, and (5) other procedures. The operational characteristics as well as the state of the art in metal fractionation of airborne particulate matter, fly ashes and workroom aerosols, in terms of applications, optimizations and innovations, are also described. Many references to other works in this area are provided.
