Atomic absorption spectroscopy verifies the detection of heavy metals down to picomolar concentrations. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=1&id=26068&type=Feature&page=1 ICP-MS was used for the quantification of Cd, Fe, Zn, and Se ions in prostatectomy samples, revealing an association between low Zn and low Fe prostate tissue levels and biochemical recurrence in prostate cancer. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=1&id=26007&type=Feature&page=1 Researchers in Spain are hoping that a standard digital camera is the perfect alternative to expensive and sophisticated laboratory instrumentation for some analytical applications. They have demonstrated how it can be used to determined potassium and magnesium concentrations and water hardness and validated the results against conventional AAS measurements. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=1&id=25973&type=Feature&page=1 Potassium or sodium/strontium co-substituted calcium polyphosphate has been developed for use as a bone repairing scaffold in the orthopedic field, giving higher cell proliferation rates and good compress resistant strength. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=1&id=25874&type=Feature&page=1 Inductively coupled plasma atomic emission spectroscopy (ICP-AES) has been used in the testing of uptake and toxicity of titania nanoparticles in earthworms as a marker of potential ecological harm. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=1&id=25807&type=Feature&page=1 Co and Cr levels in scalp hair have been measured by inductively coupled plasma-mass spectrometry as indicators for metal levels in the body after hip resurfacing arthroplasty (HRA). Both metals were greatly increased after metal-on-metal HRA. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=1&id=25693&type=Feature&page=1 It is illegal to use lead as an additive in the manufacture of pewter kitchenware, tableware, drinking cups. However, work in Brazil using atomic absorption spectroscopy not only provides a benchmark for standardizing tests for lead, cadmium and other toxic metals, but reveals that some manufacturers are flouting the law. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=1&id=25620&type=Feature&page=1 In this review, analytical methods for analysis of heavy metals in herbal medicines are discussed, including atomic absorption spectrometry, inductively coupled plasma optical emission spectrometry or mass spectrometry, X-ray fluorescence spectrometry, high-performance liquid chromatography, differential pulse polarography, neutron activation analysis and anodic stripping voltammetry. http://www.spectroscopyNOW.com/coi/cda/detail.cda?chId=1&id=25469&type=Feature&page=1 Metals and metalloid impurities are an increasing focus for pharmaceutical regulators anticipating high standards of QC/QA for pharmaceuticals. A review by a team at Bristol-Myers Squibb assesses the various techniques available to the industry.
