“…Synchrotron radiation X-ray fluorescence has previously been shown to be useful for the study of feather barb composition 15 . The Australian Synchrotron scanning X-ray fluorescence microprobe used in this study deploys a 16 keV incident energy beam focussed to several microns to create images with pixel sizes between 5–70 μm.…”

The highly organized morphogenesis of bird feathers holds important phylo- and ontogenetic information on the evolution of birds, organogenesis, tissue regeneration, and the health status of individual animals. Altered topobiological patterns are regularly used as retrospective evidence for disturbed developmental trajectories due to the past exposure to environmental stressors. Using the most advanced high-resolution (5–70 µm) X-ray fluorescence microscopy (XFM), we describe in the feathers from three species of Procellariiformes hitherto unknown, depositions of elements (Zn, Ca, Br, Cu, Fe) that are independent of pigmentation or any underlying variation in density or polymer structure. In the case of Zn, the pattern across several species of Procellariiformes, but not other species, consisted of highly regular bands of Zn numbering 30–32, which may reflect the estimated number of days of active feather growth or the duration of the moult period. Thus, speculatively, the highly consistent Zn pattern might be the result of a so far unknown diurnal systemic regulation rather than local heterogeneity amongst the follicular stem cells.

“…76 In a more unusual study, Chinese researchers determined elemental patterns in barbs of primary and secondary flight feathers of a snow petrel collected in Antarctica. 77 Other X-ray based techniques continue to be used in the air monitoring field. Chinese 78 and Portuguese 79 groups used PIXE to determine elemental composition of particles in the PM 2.5/10 range collected on filter samples.…”

“…Selenium was quantitatively retained on 0.1 g of TCP, while hydride-forming elements, such as As and Ge, and transition metals (Co, Cu, Fe and Ni) passed through the column. A 74 Se/ 77 Se double spike was used to correct for isotope fractionation during sample purification and for instrumental mass bias; long-term precision of 0.15-0.21& was reported.…”

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.

“…Heavy metal contamination in the environment is not only a relevant issue in industrial and urban areas, but also extends to the Antarctic regions. Chinese researchers 369 performed SRXRF measurements to determine the metal content throughout the total length of 4 single barbs of a snow petrel's feathers (Pagodroma Nivea) collected in Antarctica. A non-uniform microscale distribution of the elements Ba, Ca, Cu, Hg, Fe, K, Mg, Ni, Pb, S, Se, Sr and Zn within and among the barbs was observed.…”
