This study reports the variation of tree-ring widths and annual variation of concentration of metals (Na, Mg, Fe, Ni, Cu, Zn, Pb) in pine growing nearby chemical factories. The conifers (Pinus silvestris L.) investigated in this study covered the time span from 1920s to 2010 AD. Tree-ring widths were measured, dated and rechecked using the COFECHA. Radial trace-element profiles were determined by Laser Ablation Inductively Coupled Plasma Mass Spectrometry. The combined usage of tree ring width and chemical composition of wood provides historic records of anthropogenic impact on the environment and allows identifying the behavior adaptation of trees to the pollution. Data of pine tree cores collected from the sites nearby chemical factories show increasing levels of pollution linked to the increasing of industrial activities in Poland and subsequent dust fallout around the site. This study evidences that tree rings can be used as archives of past environmental contamination.

“…Monticelli et al, 2009). Of note, other studies of element distribution in coniferous species have shown significant differences in concentrations between earlywood and latewood (e.g., pine -Hoffmann et al, 1994;cedar -Monticelli et al, 2009).…”

“…This group also includes the laser ablation (LA) ICP-MS method (e.g. Hoffmann et al, 1994;Garbe-Schönberg et al, 1997;Watmough et al, 1997;Witte et al, 2004;Burnett et al, 2007;Monticelli et al, 2009 andNovak et al, 2010). An important advantage of these microprobebased methods for dendrochemistry is the relatively small amount of material required for analysis in comparison with wood digestion methods, which makes them ideal for analyzing tree rings and producing annually-toseasonally resolved chemical records.…”

“…Consequently, an unprocessed tree core seems like the best compromise, but it too may harbour contamination from the borer used to extract the tree core. To minimalize the potential effects of contaminated wood surfaces during LA, commonly a surface wood layer is removed by ablation prior to the formal analysis (Hoffmann et al, 1994;Garbe-Schönberg et al, 1997;Prohaska et al, 1998 andMonticelli et al, 2009), an additional step that significantly increases the analytical time. Alternatively, other approaches simply discard the first part of the recorded signal (e.g., ~10 seconds, Burnett et al, 2007), which is more time efficient and particularly appropriate when the ablation time is relatively long.…”

Some considerations in the reconstruction of lead levels using laser ablation: lessons from the design stage of dendrochemistry study, St.John's, Canada

Study of soils in St. John's, Canada showed elevated Pb levels representing a potential exposure risk for young children. Old trees growing in the city present a potential annually-resolved record of Pb levels over past centuries that provides important temporal and spatial dimensions to Pb exposure risk assessment. This paper reports the results of our analytical tests to develop a fast, reliable and cost-efficient method using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) for measuring Pb concentration in annual tree rings from available tree species. Our tests focused on approaches to sample preparation as they affect the laser ablation process, the relative merits of the ablation sampling method, and the response of our available tree species, which have contrasting wood structures, to laser ablation. The range of annual Pb concentrations (ppm) measured for each of the study species were as follows: spruce (0.18-6.42); elm (0.12-7.91); and horse chestnut (0.40-14.09). Our results demonstrate that the cutting procedure for preparing tree cores produced the most consistent Pb concentrations of the three methods, although they each displayed problematic anomalies. The selection of the best laser ablation technique appears to be highly dependent on study species and goals. In general, spot analysis permits detailed and targeted studies of tree-ring structures, but requires careful sampling attention for species with complex wood anatomy. The line scan method is ideal for reconstructing annually resolved element concentrations from trees and to some degree mitigates the complicating issue of intra-ring variability. Horse chestnut was determined to be the best of the available tree species because it exhibited a good response to laser ablation and produced the lowest intra-ring variations in Pb concentration.

In the following section some experimental details are presented concerning the calibration of the analytical procedure (LA ICP MS) applied to the analysis of a high-purity copper material.…”

High Purity Metals as Primary Calibration Materials for Elemental Analysis-Their Importance and Their Certification

et al. 2002

View full text Add to dashboard Cite

The Bundesanstalt für Materialforschung und -prüfung, BAM (Federal Institute for Materials Research and Testing) continues to establish a system of primary reference materials to meet the demands of metrological traceability. The materials act as national standards in the field of elemental analysis. For all elements of the periodic table-excepting those that are gases or radioactive-two different kinds of reference materials are being certified. The substances are of very high purity and of defined stoichiometry. Pure elements and metals are used as far as possible. They are certified by determining the trace contents of most elements of the periodic table at very low levels using different trace element analysis methods. Recent application of these methods is described and examples of the certification of some pure metals (copper, iron and lead) are given.
