The presence of potentially toxic elements and compounds in foodstuffs is of intense public interest and thus requires rapid and accurate methods to determine the levels of these contaminants. Inductively coupled plasma mass spectrometry is a powerful tool for the determination of metals and nonmetals in fruit juices. In this study, 21 commercial fruit juices (apple, peach, apricot, orange, kiwi, pear, pineapple, and multifruit) present on Romanian market were investigated from the heavy metals and mineral content point of view by ICP-MS. Our obtained results were compared with those reported in literature and also with the maximum admissible limit in drinking water by USEPA and WHO. For Mn the obtained values exceeded the limits imposed by these international organizations. Co, Cu, Zn, As, and Cd concentrations were below the acceptable limit for drinking water for all samples while the concentrations of Ni and Pb exceeded the limits imposed by USEPA and WHO for some fruit juices. The results obtained in this study are comparable to those found in the literature.

Abstract A comparison was carried out between quadrupole inductively coupled plasma mass spectrometry (ICP-QMS) detection and sector field ICP-MS (ICP-SFMS) detection for quantification of elements such as arsenic (As), cadmium (Cd), copper (Cu), lead (Pb), zinc (Zn), and uranium (U) in drinking water. A drinking water sample obtained from the International Atomic Energy Agency was used for validation measurement methods. ICP-QMS and ICP-SFMS obtained recoveries of 95–107% and 95–105%, respectively. Moreover, the relative standard deviation for ICP-QMS was <5% in comparison with ICP-SFMS, which was <2%. The limits of detection obtained in ICP-MS and ICP-SFMS for each element were under ng L−1, except for Zn. Both methods were applied to evaluate these elements in drinking water for consumption in Mexico. According to Mexican Regulation for Human Drinking Water NOM-201-SSA1-2015 and Environmental Protection Agency (EPA) from the United States, the values are within the allowable limits. In conclusion, ICP-QMS and ICP-SFMS are excellent choices for measurements of these toxic elements in water samples because of high precision and accuracy in routine analysis minutes, while also exhibiting excellent precision and accuracy in routine analysis.

<p>The article demonstrates the importance of using a suitable approach to compensate for dead time relate count losses (a certain measurement artefact) whenever short, but potentially strong transient signals are to be analysed using inductively coupled plasma mass spectrometry (ICP-MS). Findings strongly support the theory that inadequate time resolution, and therefore insufficient compensation for these count losses, is one of the main reasons for size underestimation observed when analysing inorganic nanoparticles using ICP-MS, a topic still controversially discussed.</p>
