“…For this purpose, ICP-MS technology is more sensitive than ICP-OES [36]. The benefits of ICP-MS technique include its high accuracy and lower detection limits as compared to GF-AAS, and it also has multi-element analysis capabilities [37].…”

Following root canal treatment, sealers may contact periapical tissue. The purpose of this study was to evaluate the systemic toxic effects of epoxy resin-based sealers (AH Plus and Obtuseal). Inductively coupled plasma-mass spectrometry (ICP-MS) was used to measure levels of trace elements (beryllium, magnesium, aluminium, calcium, chromium, arsenic and lead) in the brain, kidney and liver of rats. Twenty sterilized polyethylene tubes were then filled with AH Plus and Obtuseal and implanted into the dorsal subcutaneous tissue of 10 rats; three unoperated animals were used as a control group. After 45 days, the rats were sacrificed by cervical dislocation following anaesthesia, and brains, kidneys and livers were removed from all experimental animals. ICP-MS analysis was used to determine levels of trace elements. Data were analysed using KruskalWallis and Connover post hoc tests. No significant differences were found in aluminium and calcium levels, but brains, kidneys and livers showed significantly higher amounts of magnesium and chromium than the corresponding controls. In the kidney and liver samples, arsenic levels were found to be higher than in the control group. Lead was detected at higher levels only in liver samples from the AH Plus group. Beryllium was not detected in any organ. It was concluded that AH Plus and Obtuseal release minimal quantities of trace elements when in contact with subcutaneous tissue, and further studies are needed to understand the systemic effects of these materials.

This study covers raw fresh milk of cow, goat and camel (farm and pasture-reared), in addition to two brands of commercial milk samples, liquid milk of powder origin and drinking yoghurt samples. Camel milk showed a relatively lower pH range (6.15 -6.46) compared cow, goat and commercial milk. The pH of drinking yoghurt was found (4.35 -4.47).Microwave digestion, was selected followed by mineral analysis using Inductively Coupled Plasma-Optical Emission Spectrometry. Micro minerals; Cd, Cr, Cu, Fe, Mn and Pb, ranged from not detected to 23.4+0.52mg/L for Fe while Sr (0.32+0.005 -2.51+0.043 mg/L) and Zn (1.58+0.01 -8.91+0.14 mg/L) in all milk samples.

Celiac disease is a food intolerance triggered by the ingestion of gluten-containing cereals; the only therapy is a strict gluten-free diet for life. In recent years, gluten-free cereal bars has achieved considerable attention as an interesting alternative food considering its several advantages, such as functional properties, nutritional contents, variety of presentations and flavors. The aim of this study was to determine the contents of three toxic trace elements (arsenic, cadmium and lead) in commercial gluten-free cereal bars marketed in Argentina by ICP-MS and assess the dietary intake of the three toxic elements compared with reference values. The results obtained indicated that the highest total concentration of arsenic is provided by the gluten-free cereal bars with green apple pomace (28.2 µg/kg) and the levels of cadmium were lower than 10 µg/kg or even below MDL in all samples. The lead contents in all bars with honey samples were exceptionally higher than in the other samples (levels greater than 130 µg/kg). The intake of available gluten-free cereal bars are generally safe for consumers, but particular attention should be paid to monitor the content of arsenic and lead gluten-free cereal bars to ensure the quality of the product. Further studies are necessary to achieve an exact risk evaluation, concerning the bioavailability of trace elements in gluten-free food sources.
