Globally widespread phosphate fertilizer applications have resulted in long-term increases in the concentration of cadmium (Cd) in soils. The accumulation of this biotoxic, and bioaccumulative metal presents problems for the management of soil-plant-animal systems, because the magnitude and direction of removal fluxes (e.g., crop uptake, leaching) have been difficult to estimate. Here, Cd isotopic compositions (δCd) of archived fertilizer and soil samples from a 66 year-long agricultural field trial in Winchmore, New Zealand, were used to constrain the Cd soil mass balance between 1959 and 2015 AD, informing future soil Cd accumulation trajectories. The isotopic partitioning of soil Cd sources in this system was aided by a change in phosphate source rocks in 1998 AD, and a corresponding shift in fertilizer isotope composition. The dominant influence of mixing between isotopically distinct Cd end-members was confirmed by a Bayesian modeling approach. Furthermore, isotope mass balance modeling revealed that Cd removal processes most likely increased in magnitude substantially between 2000 and 2015 AD, implying an increase in Cd bioaccumulation and/or leaching over that interval. Natural-abundance stable isotopes are introduced here as a powerful tool for tracing the fate of Cd in agricultural soils, and potentially the wider environment.

“…Supersonic extraction has also been used in yet another modification of the Tessier sequential extraction method. 107 Soylack et al 108 described an interesting procedure for the extraction of trace amounts of Co, Cr, Cu, Fe, Mn and Pb from soils and sediments, prior to determination by AAS. The metals were coprecipitated with erbium hydroxide in a 0.05 M NaOH medium and the precipitate dissolved in 1 M HNO 3 .…”

This is the twenty-third 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 2006 and August 2007. In the analysis of air, there has been an increased awareness of the need to collect and characterise ultrafines, i.e. particles below 100 nm in size, and such work is being facilitated by the development of real-time aerosol mass spectrometric techniques. In the analysis of plant and water matrices, elemental speciation protocols for elements such as As, Cr Hg, Sb, Se and Sn continue to receive considerable attention with particular interest in the speciation of Se compounds in plant matrices. Laser ablation continues continues to go from strength to strength in being adopted as a solid sampling tool in geochemical analysis. Such work is being underpinned by increased knowledge of the ablation process and resultant transport and plasma effects coupled with developments in fs UV laser technology. This technique, in conjunction with multi-collector ICP-MS technology, is increasingly being used for the in situ determination of isotope ratios in geological samples. Feedback on this review is most welcome and the lead author can be contacted using the email address provided.

A comprehensive review of the single and sequential extraction schemes for metal fractionation in environmental samples such as soil and industrially contaminated soils, sewage sludge and sludge amended soils, road dust and run off, waste and miscellaneous materials along with other approaches of sequential extraction methods are being presented. A discussion on the application of chemometric methods in sequential extraction analysis is also being given. The study of single and sequential extraction methods for various reference materials are also being looked into. The review covers several aspects of the single and sequential extraction methodologies. The use of each reagents involved in these schemes are also discussed briefly. Finally the present upto date information by different workers in various fields of environmental geochemistry along with the possible future developments are also being outlined.
