“…This technique has been used previously to determine the chemical composition and distribution of elements in airborne particulate matter collected on filters (Tanaka et al, 1998;Chin et al, 1999;Wang et al, 1999;Okuda et al, 2004;Gligorovski et al, 2008;Hsieh et al, 2011). For calibration, we employed a simple process consisting of spiking the filters with standard solutions, as applied by Tanaka et al (1988) and recently by Hsieh et al (2011).…”

Fireworks displays are among the most important events during Taiwan's annual Lantern Festival, although thus practice leads to metal and non-metal pollution in the air. In this study, we investigated the levels of 16 elements-Na, Mg, Al, Si, K, Ca, V, Cr, Mn, Fe, Cu, Zn, As, Sr, Ba, and Pb-during the fireworks festival in Yanshui, Tainan, Taiwan, and the chemical compositions and mass concentration distributions of these elements collected from the sampling site are reported. The airborne particles were mainly in the sub-micrometer regime, with coarse size ranges. The concentrations of most of the elements of interest in this study were higher in the post-fireworks display period than prior to it. Studies of respiratory epithelial cell death revealed that the levels of the elements collected in the sub-micrometer size range were more than two times lower than those in the micrometer size range in the post-fireworks display period, but the viability was 65.7% for the former compared with 73.3% for the latter. Accordingly, the toxicity of the sub-micrometer particles was greater than that of the micrometer-sized particles. We conclude that the burning of fireworks during the festival was the main source of the trace metals, and contributed significantly to the increase in airborne particulate matter.

“…For these reasons, the only possibility to optimize the determination of total chromium in these materials is to compare the efficiency of different digestion procedures. Among reagents generally used for digestion, hydrofluoric acid is often recommended for total chromium determination in solid inorganic matrices because HF destroys the difficult-to-digest silicates that have a strong affinity for chromium [6]. Due to the absence of silicates from our samples, HF was not required.…”

“…The choice of HCl and H 2 SO 4 was also rejected because they can interfere with the measurement of the 52 Cr + and 53 Cr + isotopes by ICP-MS. Furthermore, some studies have shown that chromium losses through volatilisation into CrO 2 Cl 2 could occur with hydrochloric acid [6,9]. Consequently, two protocols were tested:…”

A European directive was recently adopted limiting the use of hazardous substances such as Pb, Hg, Cd, and Cr(VI) in vehicle manufacturing. From July 2003 a maximum of 2 g Cr(VI) will be authorised per vehicle in corrosion-preventing coatings of key components. As no standardised procedures are available to check if produced vehicles are in agreement with this directive, the objective of this work was to develop analytical procedures for total chromium and Cr(VI) determination in these materials. The first step of this study was to optimise digestion procedures for total chromium determination in plastic and metallic materials by inductively coupled plasma mass spectrometry (ICP-MS). High resolution (HR) ICP-MS was used to examine the influence of polyatomic interferences on the detection of the (52)Cr(+) and (53)Cr(+) isotopes. If there was strong interference with m/ z 52 for plastic materials, it was possible to use quadrupole ICP-MS for m/ z 53 if digestions were performed with HNO(3)+H(2)O(2). This mixture was also necessary for digestion of chromium from metallic materials. Extraction procedures in alkaline medium (NH(4)(+)/NH(3) buffer solution at pH 8.9) assisted by sonication were developed for determining Cr(VI) in four different corrosion-preventing coatings by HPLC-ICP-MS. After optimisation and validation with the only solid reference material certified for its Cr(VI) content (BCR 545; welding dusts), the efficiency of this extraction procedure for screw coatings was compared with that described in the EN ISO 3613 standard generally used in routine laboratories. For coatings comprising zinc and aluminium passivated in depth with chromium oxides the extraction procedure developed herein enabled determination of higher Cr(VI) concentrations. This was also observed for the screw covered with a chromium passivant layer on zinc-nickel. For coating comprising a chromium passivant layer on alkaline zinc the standardized extraction procedure was more efficient. In the case of painted metallic plate, because of a reactive matrix towards Cr(VI), its extraction without degradation was difficult to perform.

We applied laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) techniques to make spatial measurements of chemical tracer concentrations in three natural rock types (tuff, sandstone, greywacke) in order to characterize important processes affecting chemical fate and transport (e.g., diffusion, sorption, imbibition, and advective transport). Specifically, we (1) evaluated LA-ICP-MS factors (e.g., spot size, laser pulse, primary grain size, and surface roughness) affecting quantitative laser sampling in both surface and depth mapping; and (2) applied LA-ICP-MS to investigate the fate and transport processes of a suite of chemicals (both nonsorbing and sorbing) in natural rock through laboratory studies of imbibition, diffusion under both saturated and unsaturated conditions, and transport in a rock core traversed by a saw-cut fracture. The results indicate that micro-scale mapping using LA-ICP-MS is a robust and sensitive technique for evaluating fate and transport of chemical species in natural rock. Direct mapping of chemical distributions using LA-ICP-MS techniques in natural rock offers distinct advantages over other methods of study, such as batch sorption experiments using crushed rock samples, and through-diffusion studies involving lengthy experiments during which test conditions may be difficult to maintain. Values of sorption distribution coefficient as determined using LA-ICP-MS techniques with centimeter-sized tuff samples, are consistently smaller, in both imbibition and diffusion experiments, than those obtained from batch-sorption tests using crushed samples with grain sizes in the 0.5-2.0 mm range.
