“…One of the most promising techniques for ultra-trace multi-element analysis is inductively coupled plasma mass spectrometry (ICP-MS), which is becoming more widely used in the occupational health field. [9][10][11] To address the need for harmonized ICP-MS methods for use by occupational hygiene laboratories, international voluntary consensus standard ICP-MS test methods have been recently developed and promulgated by ASTM International 12 and the International Organization for Standardization (ISO). 13 These consensus standard methods describe aspects of sampling and sample preparation as well as analysis by ICP-MS.…”

Inductively coupled plasma mass spectrometry (ICP-MS) is becoming more widely used for trace elemental analysis in the occupational hygiene field, and consequently new ICP-MS international standard procedures have been promulgated by ASTM International and ISO. However, there is a dearth of interlaboratory performance data for this analytical methodology. In an effort to fill this data void, an interlaboratory evaluation of ICP-MS for determining trace elements in workplace air samples was conducted, towards fulfillment of method validation requirements for international voluntary consensus standard test methods. The study was performed in accordance with applicable statistical procedures for investigating interlaboratory precision. The evaluation was carried out using certified 37-mm diameter mixed-cellulose ester (MCE) filters that were fortified with 21 elements of concern in occupational hygiene. Elements were spiked at levels ranging from 0.025 to 10 μg filter −1 , with three different filter loadings denoted "Low", "Medium" and "High". Participating laboratories were recruited from a pool of over fifty invitees; ultimately twenty laboratories from Europe, North America and Asia submitted results. Triplicates of each certified filter with elemental contents at three different levels, plus media blanks spiked with reagent, were conveyed to each volunteer laboratory. Each participant was also provided a copy of the test method which each participant was asked to follow; spiking levels were unknown to the participants. The laboratories were requested to prepare the filters by one of three sample preparation procedures, i.e., hotplate digestion, microwave digestion or hot block extraction, HHS Public Access Author Manuscript Author ManuscriptAuthor Manuscript Author Manuscript which were described in the test method. Participants were then asked to analyze aliquots of the prepared samples by ICP-MS, and to report their data in units of μg filter −1 . Most interlaboratory precision estimates were acceptable for medium-and high-level spikes (RSD <25%), but generally yielded greater uncertainties than were anticipated at the outset of the study.

Amid the traditional development and applications work reported during the period covered by this review, the most obvious identifiable trend is that of downsizing. This is seen with techniques requiring smaller sample sizes or more effective analyte pre-concentration, and with new instrumentation. Procedures for extraction included the use of nanoparticles in various ways and the single-drop methodology with one example exploiting 1-dodecanol, a material that shifts between liquid and

“…In this experiment, different building composites from y ash, EAF dust and cement were prepared and immersed into MilliQ water for two different times (1 day or 9 months). Due to the presence of soluble Ca(OH) 2 and CaCO 3 arising from the building composites, the pH values of the leachates were highly alkaline. 20 In samples immersed for 1 day into MilliQ water the pH was 11, while in those immersed for 9 months, it was 13.…”

“…High performance liquid chromatography (HPLC) coupled to an inductively coupled plasma mass spectrometry (ICP-MS) detector is a powerful tool for the elemental speciation analysis in a variety of environmental and biological samples. [1][2][3] Despite the possibility of multielemental detection, speciation analysis by HPLC-ICP-MS is usually carried out separately for the species of a particular element. Simultaneous speciation analysis of two or more elements is possible only if the chemical species of different elements behave similarly during the analysis.…”

Flay ash, cement and electric arc furnace (EAF) dust are frequently mixed in building composites. From them, chromium (Cr), arsenic (As), molybdenum (Mo) and vanadium (V) may be leached. Concentrations of V in leachates may be significantly higher than those of Cr, As and Mo, making simultaneous speciation analysis particularly difficult. In this work, a high performance liquid chromatography inductively coupled plasma mass spectrometry (HPLC-ICP-MS) procedure was used for simultaneous speciation of chromate, arsenate, molybdate and vanadate. First, the behaviour of Cr, As, Mo and V species in different oxidation states was studied during their separation under acidic (pH 5) and alkaline (pH 12) conditions. At alkaline pHs chromate, arsenate, molybdate and vanadate were simultaneously separated and eluted at retention times from 390 to 450 s, 230 to 270 s, 340 to 430 s and 270 to 380 s, respectively and detected on-line by ICP-MS, recording m/z 52, 75, 95 and 51, respectively. When V species were leached in significantly higher concentrations than Cr, Mo and As, their detection was possible at the low abundance (0.25%) 50 V isotope, which is also the mass of the 50 Cr isotope (abundance 4.345%), due to selective separation between V and Cr species. Good repeatability of measurement (RSD better than AE3.0%) and quantitative elution of elemental species (column recoveries 99-105%) were obtained. Finally, the procedure was applied in the simultaneous speciation analysis of chromate, arsenate, molybdate and vanadate in highly alkaline aqueous leachates from composites consisting of fly ash, cement and EAF dust that contained a wide range of concentrations of vanadate.
