Objective Teeth can serve as records of environmental exposure to heavy metals during their formation. We applied a new technology -synchrotron radiation microbeams (SRXRF) -for analysis of heavy metals in human permanent teeth in modern and historical samples. Methods Each tooth was cut in half. A longitudinal section 200 lm in thickness was subjected to the determination of the heavy metal content by SRXRF or conventional analytical methods (ICP-MS analysis or reduction-aeration atomic absorption spectrometry). The relative concentrations of Pb, Hg, Cu and Zn measured by SRXRF were translated in concentrations (in g of heavy metal/g of enamel) using calibration curves by the two analytical methods. Results Concentrations in teeth in the modern females (n = 5) were 1.2 ± 0.5 lg/g (n = 5) for Pb; 1.7 ± 0.2 ng/g for Hg; 0.9 ± 1.1 lg/g for Cu; 150 ± 24.6 lg/g for Zn. The levels of Pb were highest in the teeth samples obtained from the humans of the Edo era (1603-1868 AD) (0.5-4.0 lg/g, n = 4). No trend was observed in this study in the Hg content in teeth during 3,000 years. The concentrations of Cu were highest in teeth of two medieval craftsmen (57.0 and 220 lg/g). The levels of Zn were higher in modern subjects (P \ 0.05) than those in the Jomon (*1000 BC) to Edo periods [113.2 ± 27.4 (lg/g,

Laser ablation is becoming a dominant technology for direct solid sampling in analytical chemistry. Laser ablation refers to the process in which an intense burst of energy delivered by a short laser pulse is used to sample (remove a portion of) a material. The advantages of laser ablation chemical analysis include direct characterization of solids, no chemical procedures for dissolution, reduced risk of contamination or sample loss, analysis of very small samples not separable for solution analysis, and determination of spatial distributions of elemental composition. This review describes recent research to understand and utilize laser ablation for direct solid sampling, with emphasis on sample introduction to an inductively coupled plasma (ICP). Current research related to contemporary experimental systems, calibration and optimization, and fractionation is discussed, with a summary of applications in several areas.

Outer and/or worn enamel was not sampled as it has been shown to be consistently enriched in, or depleted of, a number of trace elements examined here (see Budd et al 1998;Lee et al 1999;Reitznerová 2000;Dolphin et al 2005). Figure 2.…”
