Caldelas C, Dong S, Luis Araus J, Weiss DJet al., 2011, Zinc isotopic fractionation in Phragmites australis in response to toxic levels of zinc, Journal of Experimental Botany, Vol: 62, Pages: 2169-2178, ISSN: 1460-2431

Stable isotope signatures of Zn have shown great promise in elucidating changes in uptake and translocation mechanisms of this metal in plants during environmental changes. Here this potential was tested by investigating the effect of high Zn concentrations on the isotopic fractionation patterns of Phragmites australis (Cav.) Trin. ex Steud. Plants were grown for 40 d in a nutritive solution containing 3.2 μM (sufficient) or 2 mM (toxic) Zn. The Zn isotopic composition of roots, rhizomes, shoots, and leaves was analysed. Stems and leaves were sampled at different heights to evaluate the effect of long-distance transport on Zn fractionation. During Zn sufficiency, roots, rhizomes, and shoots were isotopically heavy (δ66ZnJMC Lyon=0.2‰) while the youngest leaves were isotopically light (–0.5‰). During Zn excess, roots were still isotopically heavier (δ66Zn=0.5‰) and the rest of the plant was isotopically light (up to –0.5‰). The enrichment of heavy isotopes at the roots was attributed to Zn uptake mediated by transporter proteins under Zn-sufficient conditions and to chelation and compartmentation in Zn excess. The isotopically lighter Zn in shoots and leaves is consistent with long-distance root to shoot transport. The tolerance response of P. australis increased the range of Zn fractionation within the plant and with respect to the environment.

Analysis of naturally occurring isotopic variationsis a promising tool for investigating Zn transport andcycling in geological and biological settings. Here, wepresent the recently installed double-spike (DS) techniqueat the MAGIC laboratories at Imperial College London.The procedure improves on previous published DS methodsin terms of ease of measurement and precisions obtained.The analytical method involves addition of a 64Zn–67Zndouble-spike to the samples prior to digestion, separation ofZn from the sample matrix by ion exchange chromatography,and isotopic analysis by multiple-collector inductivelycoupled plasma mass spectrometry. The accuracy andreproducibility of the method were validated by analysesof several in-house and international elemental referencematerials. Multiple analyses of pure Zn standard solutionsconsistently yielded a reproducibility of about ±0.05‰(2 SD) for δ66Zn, and comparable precisions were obtainedfor analyses of geological and biological materials. Highlyfractionated Zn standards analyzed by DS and standardsample bracketing yield slightly varying results, whichprobably originate from repetitive fractionation eventsduring manufacture of the standards. However, the δ66Znvalues (all reported relative to JMC Lyon Zn) for two lessfractionated in-house Zn standard solutions, Imperial Zn(0.10±0.08‰: 2 SD) and London Zn (0.08±0.04‰), arewithin uncertainties to data reported with different massspectrometric techniques and instruments. Two standardreference materials, blend ore BCR 027 and ryegrass BCR281, were also measured, and the δ66Zn were found to be0.25±0.06‰ (2 SD) and 0.40±0.09‰, respectively. Takentogether, these standard measurements ascertain that thedouble-spike methodology is suitable for accurate andprecise Zn isotope analyses of a wide range of naturalsamples. The newly installed technique was consequentlyapplied to soil samples and soil

We evaluate the ability of the regional chemistry/aerosol climate model REMOTE to simulate Asian dust transport over China in response to changing Asian monsoon conditions. Applied to years of different monsoon strength, model results are compared to dust fluxes measured in a 9.5 kyr peat core from NW Szechuan. This palaeoclimate archive provides an uninterrupted history of Holocene monsoon conditions and dust fluxes to the Eastern Tibetan Plateau and represents a solid longterm framework for evaluating model responses to climate change. We present preliminary model results for selected months of the year 1996, which displayed normal monsoon conditions. Simulation results suggest that dust deposition to the Eastern Tibetan Plateau is dominated by wet deposition during monsoon and pre-monsoon months. Model deposition fluxes agree within a factor of two with fluxes from relevant sections of the peat core, providing encouraging new data in the bid to assess future impacts of dust on climate. The yearly simulations must henceforth be carried out under dry and wet monsoon conditions and compared to relevant sections of the core. ©2010 IEEE.
