“…While many investigations of the quality values of medicinal plants are being reported in the literature, less attention has been paid to the metal content of herbal products. Some heavy metals are essential for the human body, some, however, may be poisonous if present at sufficiently high concentrations (Flick et al, 1978;Flores et al, 2009). If they enter the human body, they may disturb the normal functions of the central nervous system, liver, lungs, heart, kidney and brain, resulting in hypertension, abdominal pain, skin eruptions and intestinal ulcer, and they cause various types of cancers (Järup, 2003;Kabata-Pendias and Mukherjee, 2007).…”

The purpose of this study was to perform a comparative study of cations in the vegetative organs of Sambucus ebulus by applying three different methods of digestion before atomic absorption spectrometry. Of the tested methods, the most effective was method 3 (mineralisation with nitric acid in a microwave oven), the other methods of sample digestion leading to incomplete mineralization of the samples and implicitly to the incomplete transfer of the analytes into solution, reflecting the slightly different contents in metal cations we obtained.

“…Whilst a high degree of precision permits a range of geological questions to be addressed, confirming the accuracy of the data remains a challenge, as bias can easily be introduced during chemical preparation and analysis. 194 Pt. The procedure required the measurement of three Pt isotope ratios, which was performed on a quadrupole ICP-MS instrument.…”

“…A procedure developed by Palesskii et al371 employed isotope dilution to improve the accuracy of PGE measurements. Samples were spiked with191 Ir,190 Os,106 Pd,194 Pt,185 Re and99 Ru before microwave digestion with a 1+3 mixture of HCl and HNO 3 . The analytes were separated from the matrix by cation exchange on BioRad AG 50Wx8 resin; the eluant obtained was suitable for direct analysis by an SF-ICP-MS instrument fitted with an ultrasonic nebuliser.…”

This is the twenty-fifth 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 2008 and August 2009. In the analysis of air, work is focused on the need to collect and characterise ultrafines; determination of elements such as Be, Hg and PGEs in air samples; application of SRXRF techniques and advances in the development of field deployable aerosol mass spectrometry systems. In the analysis of water, significant areas of activity currently focus on elemental speciation of As, Cr, Hg and Sn. Work in increasing method sensitivities through the use of vapour generation and optimization of extraction and preconcentration procedures continues. The increased global awareness of the need to monitor levels of potentially toxic elements (PTE) in soils is desirable and this is reflected in a growing body of published literature from authors in the Middle East, Asia and Africa. However, a potential criticism of some studies is that they simply report the concentrations of analytes in particular soils or plants, without providing sufficient information on analytical quality control and with little assessment of their environmental significance, e.g. those levels that are a threat to human health. In the field of geological analysis, considerable effort is being spent not only on the production, characterization and certification of new geological reference materials, but also on enhancing the certification of existing reference materials and the development of reference materials with assigned elemental isotopic ratios. Laser ablation continues to go from strength to strength in being adopted as a solid sampling tool in geochemical analysis.
