“…In contrast, the highest level of arsenic was observed in store label fish purees (346.2 ng/g), being significantly higher than those observed in name brands (212.5 ng/g, p = 0.001; Table 2 ). Fish and rice are the main sources of arsenic exposure [ 39 , 40 ]. Compared to the food with the lowest concentration of arsenic (5.5 ng/g in store brands of fruit purees), 63 times more arsenic was observed in the fish puree ( Table 2 ).…”

Background: The infant population is particularly sensitive, so the risk posed by their diet must be analyzed. The aims of the present study were (i) to determine the contents of 38 elements in 159 samples of ready-to-eat baby food sold in Spain and (ii) to estimate the dietary intakes and risk assessments of these elements in name brands and store brands in infants ranging between 6 and 12 months of age. Methods: A list of essential, non-essential/toxic elements, rare earth elements (REEs), and other hi-tech-related elements that are currently considered as emerging environmental pollutants were measured in ready-to-eat baby foods by ICP-MS. Results: Fish purees showed the highest concentrations of mercury (28.1 ng/g) and arsenic (346.2 ng/g). The levels of manganese, molybdenum, and chromium exceed the adequate intake, being higher in the case of store brands. The acute hazard index was above 1 for molybdenum and manganese. A risky consumption of thallium and mercury was observed, being higher among name brands. The risk associated with the consumption of REEs was low, although its presence should be highlighted. Conclusions: This is the first time that these chemical elements have been measured in ready-to-eat purees for babies. The presence of some of them, such as mercury, should be sufficient to monitor the levels of these contaminants in food intended for such a sensitive population as children.

Currently, biomonitoring research is actively developing in the Arctic region, despite this, groups of people who temporarily come to the Arctic remain outside the national monitoring system, unlike the local population. Participation in expeditions on ships implies special living conditions, such as limited space, sensory deprivation. The study aims to analyse the biochemical parameters of blood, the content of essential, toxic elements, persistent organic pollutants (POPs) and vitamin D in samples of the expedition group temporarily coming to work in extreme Arctic conditions. Scientists carried out a study on board the Mikhail Somov scientific expedition vessel as part of the Arctic Floating University project. The participants were 50 people: 26 men and 24 women aged 20 to 72 years. As a result of the analysis, the authors have determined: 8 biochemical blood parameters, vitamin D levels by high-performance liquid chromatography with tandem mass spectrometric detection, the content of essential (Co, Mn, Se, Cu, Zn), toxic elements (As, Cd, Hg, Pb) using an inductively coupled plasma mass spectrometer and POPs by gas chromatography-mass spectrometry. Almost 90% of the expedition participants had vitamin D concentrations below 20 ng/ml, which indicates a deficiency of this vitamin in the body. After conducting a comparative analysis between the expedition group and the permanent population of the Nenets Autonomous Okrug (NAO), it was found that the expedition group significantly reduced the content of not only toxic compounds (As, Cd, Hg, Pb, POPs), but also essential elements (Co, Mn, Se, Cu, Zn), according to compared to the local population. It is worth noting that the concentration of arsenic in the expedition group is 65 times lower (0.12 µg/L) than in permanent residents of the Arctic zone of the Russian Federation (7.29 µg/L), and the concentration of lead in the group of expedition workers was 42 times lower (0.30 µg/L) than in the local population (15.21 µg/L). The data obtained provide information about the elementary and toxic status of the urban population of the Russian Federation. One of the reasons for such differences may be the predominantly traditional lifestyle of the local NAO population and the biomagnification of toxic substances in food chains. If biomonitoring studies are carried out by specialists on an ongoing basis and the data obtained is accumulated, then a basis may appear for predicting risks of both a short-term and long-term nature. The conducted research contributes to the expansion of the biomonitoring system at the national level.
