“…Measurements of the elemental composition of Arctic aerosols have been conducted in the northern part of continental Siberia, on Wrangel Island, the Severnaya Zemlya Archipelago, Franz Josef Land (Rovinsky et al, 1995;Vinogradova and Polissar, 1995;Vinogradova, 1996;Koutsenogii et al, 1998Koutsenogii et al, , 2000Smirnov et al, 1998). We began aerosol research in the marine boundary layer over the seas of the Russian Arctic in 1991; some results have been published elsewhere (Shevchenko et al, 1995(Shevchenko et al, , 1999a(Shevchenko et al, ,b,c, 2000Golubeva and Shevchenko, 1999).…”

A review of the data on heavy metals in aerosols over the seas of the Russian Arctic is presented. Results of heavy metal studies in aerosols obtained during 11 research expeditions in summeryautumn period from 1991 to 2000, and at Severnaya Zemlya and Wrangel Island in spring, in 1985-1989 are discussed. Concentrations of most heavy metals in the atmosphere in the marine boundary layer in the Russian Arctic are nearly of the same order as literature data from other Arctic areas. The content of heavy metals in the aerosols over the seas of the Russian Arctic shows an annual variation with maximal concentrations during the winteryspring season. In the summeryautumn period increased concentrations of heavy metals could be explained, in most cases, by natural processes (generation of sea salt aerosols, etc.). In some cases, aerosols from Norilsk and Kola Peninsula were detected. Particular attention was paid to estimation of horizontal and vertical fluxes of atmospheric heavy metals. We estimated annual variations in long-range transport of heavy metals into the Russian Arctic in 1986-1995. In winter and spring, up to 50% of the average air pollutant concentrations in the Russian Arctic are due to the Arctic atmospheric pollution itself. Moreover, the monthly and annual averaged fluxes of six anthropogenic chemical elements (arsenic, nickel, lead, vanadium, zinc and cadmium) onto the surface in the Arctic were estimated, and the values obtained were in reasonable agreement with the literature data available. ᮊ

“…Several publications dealt with atmospheric aerosols in Siberia using both SR XRF and INAA with the aim of better understanding the sources of pollution. [107][108][109][110] Some of this work involved directly sampling the convection column of taiga forest fires using a selection of instruments, including an impactor mounted on a helicopter. Another investigation of particulate material, specifically agglomerates of 10 nm (nominal) Fe 3 O 4 particles embedded in thick epoxy resin at an overall concentration of 0.03% m/m, was undertaken by Thorpe et al 111 Using a 2 mm probe step size, results showed that spherical agglomerate particles in the size range from 100 to several thousand nm were present, formed by magnetostatic attraction in agreement with independent TEM measurements.…”

“…321 Energy dispersive XRF was utilised in the non-destructive surface analysis of nuclear fuel element plates. 322 Samples collected by dry rubbing of the entire surface of both sides of the fuel plates were analysed using a 109 Cd radioisotope excitation source to excite the L lines of the U analyte. A Si (Li) detector offering a resolution of 165 eV (at 5.9 keV) was used for measurement and a detection limit of v1 mg of U was reported.…”

“…The application of radioisotope-excited EDXRF to the analysis of plants was the subject of a review citing 41 references. 343 The 241 Am source was considered particularly useful for the determination of Ag, Cd, Dy, Mo and Sn, while 109 Cd and 238 Pu were found more appropriate to particular determinations. Radioisotope-excited EDXRF was also employed in the determination of Cu in pupae and adults of the Colorado potato beetle.…”

“…There was a noticeable increase in activity in research concerned with the accuracy and repeatability of bone-lead measurements in the year under review. Todd and co-workers [348][349][350] made significant contributions to the understanding of these issues in a series of publications addressing calibration methods for 109 Cd excited K-shell EDXRF measurements. For example, an investigation was made of the factors contributing to the differences in Pb response between the calibration sample matrix and the human bone.…”

The review also covers a survey of applications, including sample preparation, geological, environmental, archaeological, forensic, biological, clinical, thin films, chemical state and speciation studies. During the current review period, publications have demonstrated the development of sub-100 nm X-ray beams for SR microprobe analysis together with the wider use of WD spectrometers in this application. There is evidence of an extension of the application of XRF as a reference technique, with XRF increasingly being used in modern laboratories in place of older wet-chemical methods, and computer-modelling studies continue to be popular in extending the understanding of various XRF phenomena. Some interesting work has been undertaken in the measurement of radiative Auger effects using high-resolution WDXRF instruments. However, the potential for future developments in XRF is illustrated by research into ultra-high resolution microcalorimeter detector devices, which are still at the experimental stage and have not yet progressed to the status of useful practical devices.
