“…Measurements of U-Pb ages in uranium oxide minerals by LA SF-ICP-MS have also been reported recently. 386 The ability to obtain rapid in situ high precision measurements of 187 Os/ 188 Os and 186 Os/ 188 Os ratios in platinum group alloy grains by LA-MC-ICP-MS has been demonstrated by Nowell and coworkers. 387 Because of isobaric interferences from Pt, 189 Os/ 188 Os was used to correct for instrumental mass bias.…”

“…387 Because of isobaric interferences from Pt, 189 Os/ 188 Os was used to correct for instrumental mass bias. Although corrections were applied for isobaric interferences from Re and W on the Os mass spectrum, they demonstrated that accurate correction for Re is problematical when the 187 Re/ 188 Os ratio is greater than about 0.5.…”

This is the twenty-forth annual review published in JAAS of the application of atomic spectrometry to the chemical analysis of environmental samples. This Update refers to papers published approximately between September 2007 and August 2008. In the analysis of air, work is focused on the need to collect and characterise ultrafines, i.e. particles below 100 nm in size, and such research is being facilitated through the development of air sampler technologies for subsequent off-line analysis of particles and aerosol mass spectrometric techniques for real-time measurements. In the analysis of water elemental speciation and development of vapour generation techniques for metalloid species continue to attach attention. Data quality and metrological issues are receiving renewed interest in part due to an increase in water quality regulations. In the field of soil and plant analysis, elemental fraction and speciation protocols based upon sequential extraction procedures, chromatographic separation procedures and synchrotron radiation x-ray techniques continue to be utilized and developed. As noted in previous Updates, laser ablation continues to go from strength to strength in being adopted as a solid sampling tool in geochemical analysis. Work continues to be focused on the production, characterization and certification of new geological reference materials. Feedback on this review is most welcome and the lead author can be contacted using the email address provided.

“…Because of its importance, chromium chemical speciation analysis has been widely studied, and several analytical techniques has been suggested to do it, such as atomic absorption spectrometry with electrothermal atomisation (Zhu et al 2005;Krishna et al 2005;El-Shahawi et al 2005;Blas et al 2007), inductively coupled plasma mass spectrometry (Chen et al 2007;Krishna et al 2005), inductively coupled plasma optical emission spectrometry (Menegario et al 2005;Parodi et al 2005;Sumida et al 2005;Gil et al 2005) and fluorescence spectrometry (Chen et al 2005). However, the adsorptive cathodic stripping voltammetry (AdCSV) is a technique as sensitivity as versatile and can be applied to different environmental matrix, and it is also adequate to chemical speciation analysis.…”

The chemical speciation analysis of chromium in one of the most important South American Estuary was performed for the first time. Samples were collected in Patos Lagoon Estuary (Brazil) and were analysed by adsorptive cathodic stripping voltammetry, with the following analytical figures of merit: limit of detection, 0.1 nmol L(-1); precision RSD = 3%, n = 7; linearity, from limit of quantitation up to 20 nmol L(-1); and accuracy of 99.8%, expressed as recovery. No labile chromium forms were identified in samples, beside industries and a city were near the study area. It is pointed out a reverse correlation between total and non-active chromium and salinity, which could be explained by biogeochemical processes.

“…Chromium pollution is an important concern that requires effective strategies in devising an appropriate remediation technology. The concentration of chromium in natural water 1 is in the range 0.1-2.5 mg L 21 and this could increase due to the pollution from dyeing and electroplating waste effluents. Industrial effluents arising from tannery 2 is one of the sources for the leaching of chromium into the ground water.…”
