“…IDMS was used to validate the approach for Cd, Cr, Cu, Ni and Pb. A step-bystep example 157 of how to calculate the combined uncertainty for the measurement of trace metals in seawater samples by GFAAS, using Cu as an example, has been published. The evaluation of measurement uncertainty results is not systematically implemented and so this paper is a useful starting point for the uninitiated.…”

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.

“…Furnace AAS is a method for ultratrace determinations "par excellence". Systematic errors and traceability of the data here have to deal with every step in the analytical process from sampling to analysis, as shown in a tutorial paper of Duta et al (16). The process of electrothermal vaporization still is the topic of many theoretical studies.…”

“…The limits of detection obtained for As, Bi, and Sb using dual mode sample introduction were 7, 15, and 10 pg mL -1 , respectively. Similarly, Colon et al (249) investigated the possibility to determine reduced sulfur species at the microgram per liter level through H 2 S vapor formation after reaction with HCl in a commercial vapor generator coupled to ICPMS equipped with a reaction cell, thus avoiding polyatomic isobaric interferences at m/z 32 caused by 16 O 2 + and 14 N 18 O + through the elimination of the aqueous matrix. The new method was evaluated by comparison to the standard potentiometric method and was applied to the analysis of reduced sulfur species in natural waters and acid volatile sulfides in sea sediments.…”
