The study indicates that the toxic metal accumulates only in the inedible parts of shellfish. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=1&id=23630&type=Feature&page=1 The present study aimed to relate tooth-lead and blood-lead levels in children residing near a zinc-lead smelter in India, and to evaluate the effectiveness of primary teeth as bioindicators of life-long lead exposure. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=1&id=23545&type=Feature&page=1 The way in which arterial plaques form, atherogenesis, is not yet completely understood despite a significant number of research studies in this area. Now, a study using rabbits on a high-fat diet (HFD) has investigated the effects of changes in the concentrations of trace elements., iron (Fe), copper (Cu) and zinc (Zn), in several tissues using atomic absorption spectroscopy. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=1&id=23494&type=Feature&page=1 To provide information concerning the geographical distribution of selenium in the soils of Scotland, 47 arable soils selected on the basis of their parent rock were analysed by ICP-MS. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=1&id=23277&type=Feature&page=1 A simple, yet sensitive, method for detecting inorganic antimony in food packaging has been developed using cloud point extraction combined with electrothermal atomic absorption spectrometry (ETAAS). http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=1&id=23176&type=Feature&page=1 A dual-column capillary microextraction was developed for the sequential separation/preconcentration of arsenite, arsenate, monomethylarsonic acid and dimethylarsinic acid in extracts of human hair followed by electrothermal vaporization inductively coupled plasma mass spectrometry detection with iridium as permanent modifier. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=1&id=23053&type=Feature&page=1 Flame atomic absorption spectrometry (FAAS) can be used effectively as an alternative method for the determination of calcium and magnesium ions in biodiesel and fuels derived from vegetable oil, according to researchers in Brazil. The technique precludes certain preparative steps and avoids the need for some toxic organic solvents. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=1&id=22963&type=Feature&page=1 Whole blood manganese was measured in eighteen dogs with congenital portosystemic shunts, 26 dogs with nonhepatic illnesses, and 14 healthy dogs by graphite furnace atomic absorption spectrometry. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=1&id=22867&type=Feature&page=1 A study of metal contaminants in urban lakes in India using atomic absorption spectroscopy reveals that mitigation actions aimed at removing the pollution may not be a long-term remedy for the problem. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=1&id=22811&type=Feature&page=1 This back-to-basics review is aimed at the novice user and includes a guide to ICP-MS instrumentation and performance. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=1&id=22734&type=Feature&page=1 Inductively coupled plasma-optical emission spectroscopy and X-ray fluorescence have been used to investigate the content of incinerated medical waste fly ash revealing important details about elemental concentrations in this problematic waste. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=1&id=22646&type=Feature&page=1 Elemental fingerprint techniques, based on elemental contents determined by inductively coupled plasma atomic emission spectrometry (ICP-AES) and multivariate statistical analysis, have been used to differentiate eight tea cultivars. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=1&id=22561&type=Feature&page=1 Inductively coupled plasma spectroscopy and mass spectrometry revealed that natural metal chelators, so-called siderophores, which are produced by bacteria and plants, make much better absorbers of cadmium, and potentially other toxic metals, than synthetic EDTA, and so could improve the efficiency of phytoremediatioon systems. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=1&id=22505&type=Feature&page=1 <p>The board of directors of Thermo Fisher Scientific Inc. has appointed Marc N.
