Characterization of beer samples is of interest because their compositions affect the taste and stability of beer and, also, consumer health. In this work, the characterizations of 20 Romanian beers were performed by mean of Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and Isotope Ratio Mass Spectrometry (IRMS) in order to trace heavy metals and isotopic content of them. Major, minor, and trace metals are important in beer fermentation since they supply the appropriate environment for yeast growth and influence yeast metabolism. Beside this, the presence of the C4plants in the brewing process was followed. Our study has shown that the analyzed beers indicated the presence of different plant types used in brewing: C3, C3-C4mixtures, and also C4, depending on producers. Also the trace metal content of each sample is presented and discussed in this study. A comparison of the beers quality manufactured by the same producer but bottled in different type of packaging like glass, dose, or PET was made; our results show that no compositional differences among the same beer type exist.

A simple and less expensive solvent extraction method was used with inductively coupled plasma mass spectrometry (ICP-MS) in the speciation of two environmentally significant, toxic forms of arsenic: arsenite and arsenate. Dissolved inorganic arsenic species in drinking waters from reservoirs and treatment plants were determined by the inductively coupled plasma mass spectrometry analyses. Prior to the analysis the water samples were precocentrated by solvent extraction using APCDT to separate the arsenic species from elemental interferences. The detection limit of this method achieved was 0.059 gL-1. The suitability of the technique in this work is discussed in relation to risk assessment studies of public health.

Knowledge about the metal content of wine is very important, for many reasons. Depending on the element, its quantity varies in wine from ng/L to mg/L. Despite the fact that metals are not directly connected to the taste and aroma of the wine, their content should be determined and controlled, because excess is undesirable, and in some cases prohibited, due to potential toxicity. Several analytical procedures for metal determination are applied. However, due to sensitivity, low limit of detection and speed of analysis, inductively coupled plasma-mass spectrometry (ICP-MS) is one of the most frequently used techniques. The aim of this study was to reveal specific relationships between the wine samples or between the chemical variables in order to classify the wines according to their metal content by application of chemometric analysis. For metals content determination, two techniques, ICP-MS and inductively coupled plasma-optical emission spectrometry (ICP-OES), were applied. Data obtained showed that none of the wine samples surpassed the toxic levels reported for metals in the literature, thus, these wines appeared to be safe as regards the risk associated with the potentially toxic metals intake. However, specific correlations between metals and specific aspects of the wines themselves have been found.

A dual-cloud point extraction (d-CPE) technique combined with inductively coupled plasma mass spectrometry (ICP-MS) was used for preconcentration and determination of Cr, Ga, Ag, Cd, Mn, Fe, In, Cu, Ni, Co, Pb and Zn in real water samples.
