The objective of this study was to investigate the content of essential elements in medicinal plants in the Kingdom of Saudi Arabia (KSA). Five different medical plants (mahareeb (Cymbopogon schoenanthus), sheeh (Artemisia vulgaris), harjal (Cynanchum argel delile), nabipoot (Equisetum arvense), and cafmariam (Vitex agnus-castus)) were collected from Madina city in the KSA. Five elements Fe, Mn, Zn, Cu, and Se were determined by using inductively coupled plasma mass spectrometry (ICP-MS). Fe levels were the highest and Se levels were the lowest in all plants. The range levels of all elements in all plants were as follows: Fe 193.4–1757.9, Mn 23.6–143.7, Zn 15.4–32.7, Se 0.13–0.92, and Cu 11.3–21.8 µg/g. Intakes of essential elements from the medical plants in infusion were calculated: Fe 4.6–13.4, Mn 6.7–123.2, Zn 7.0–42.7, Se 0.14–1.5, and Cu 1.5–5.0 µg/dose. The calculated intakes of essential elements for all plants did not exceed the daily intake set by the World Health Organization (WHO) and European Food Safety Authority (EFSA). These medicinal plants may be useful sources of essential elements, which are vital for health.

In terms of nutrition, dates are an important commodity because they are a source of carbohydrates and minerals. Saudi Arabia is the second largest producer of dates worldwide. Khalas is the tenth most popular date type in the Kingdom of Saudi Arabia (KSA), but only limited information related to the levels of essential nutrients in Khalas dates is available. The concentrations of Mn, Cu, Zn, and Se were determined using inductively coupled plasma-mass spectrometry (ICP-MS). The average concentrations in wet weight were as follows (mg/kg): Mn (2.90 ± 0.54), Cu (1.78 ± 0.64), Zn (1.72 ± 0.42), and Se (0.10 ± 0.06). The calculated intakes (μg/kg bw day) per 100 g dates for each element were as follows: Mn (4.14), Cu (2.54), Zn (2.46), and Se (0.14), which represent 0.14%, 0.51%, 0.25%, and 0.2%, respectively, of the provisional maximum tolerable daily intake (PMTDI) recommended by the EFSA/WHO. It was found that levels of the analysed essential elements in up to 100 g of Khalas dates do not exceed the level set by the EFSA/WHO.

Arsenic-hypertolerant bacteria were isolated from arsenic-contaminated well water from the village of Los Pereyra in Tucumán province, Argentina. Microorganisms that biotransform arsenic are a major factor in arsenic mobilization in contaminated aquifers. Groundwater analyses showed a level of arsenic contamination (mean concentration of 978 μg·L−1) that exceeds the safe drinking water limit of 10 μg·L−1recommended by the World Health Organization and the Argentine Food Code. There was considerable spatial variability in the concentration of arsenic in each of the wells analyzed and in the distribution of the major anions HCO3–, SO42–, and Cl–. Eighteen bacterial strains were characterized. Six strains belonging to the Actinobacteria phylum were able to grow in media with 20 mmol·L–1As(III) or 200 mmol·L–1As(V) and were also highly resistant to Cr, Cd, and Cu. Their ability to biotransform arsenic was examined by speciation of the products by high-performance liquid chromatography inductively coupled plasma mass spectrometry. In addition, two strains, Brevibacterium sp. strain AE038-4 and Microbacterium sp. strain AE038-20, were capable of aerobic arsenate reduction, which suggests that these strains could increase the mobility of arsenic by formation of more mobile As(III).

Heavy metal exhibit toxic and persistent characteristics, can enter into the food chains and the ecosystem where they cause adverse impact on the biotic and abiotic components of ecosystem. Heavy metal pollution in Malaysia has become a major health concern for humans. Thus, this study was conducted to determine the level of cadmium (Cd) and nickel (Ni) in the muscle and gill of fishes collected from the Sungai Kuantan and Sungai Riau. Field sampling was conducted between September and December 2017. Five different species of fishes: Barbonymus gonionotus (Lampam Jawa), B. schwanenfeldii( Lampam Sungai), Hampala macrolepidota(Sebarau), Chitala chitala (Belida), and Hemibagrus nemurus(Baung) were digested by using acid digestion method and analysed with Inductively Coupled Plasma-Mass Spectrometry (ICPMS). Concentration of Cd among species were in order of: H. macrolepidota >B.gonionotus> B. schwanenfeldii> C.chitala> H.nemurus, whereas Ni level in fishes were: C. chitala> H. macrolepidota> B. gonionotus> H. nemurus> B. schwanenfeldii. Among all the species, H. macrolepidota from Sungai Kuantan had the highest Cd in both muscle (0.1761±0.0062¬mg/kg) and gills (0.2938±0.0066mg/kg) whereas the highest Ni level in muscle was noted in C. chitala from Sungai Kuantan with (0.1473±0.0755 mg/kg) and in gills of B.gonionotus (0.4544±0.0470mg/kg) from the same river respectively. It was obtained that there was a significant difference (p<0.05) of Cd in muscle between species. Ni concentration in fishes was below the permissible limit stipulated by World Health Organizations WHO (1985) and Food and Agriculture Organizations (2012) but the concentration of Cd was recorded high. However, it was still below the World Health Organization (WHO) 1985 and Malaysian Food Act (MFA) 1983.

Abstract The aim of this study was to determine the levels of Zn, Cu, and Fe in three canned fish species marketed Serbia to see if they meet recommended daily intake requirements or exceed safety limits. We collected a total of 207 samples of canned tuna, sardine, and mackerel, in oil or tomato sauce and analysed them with inductively coupled plasma mass spectrometry (ICP-MS) after acid digestion. The highest levels were obtained for Zn (15.1 mg kg-1) and Cu (1.37 mg kg-1) in sardine in oil and tomato sauce, respectively, and for Fe (18.98 mg kg-1) in mackerel in tomato sauce. Our results keep within the ranges reported by several national food databases and available literature data, with a few exceptions. Our findings also single out canned sardines as the richest source of the three essential elements combined. The estimated daily intake (EDI) of the three essential elements, however, was subpar, and ranged between 0.14 % and 0.72 % of the recommended dietary allowance (RDA) for Zn, Cu, and Fe.

Abstract The present study evaluated the levels of Mn, Se, Cu and Zn in beef cuts available at markets in Serbia. We also assessed the risk associated with the consumption of these foods based on the estimated daily intake (EDI) of these elements. Thirty-six beef meat cuts were analysed using inductively coupled plasma mass spectrometry (ICP-MS). The EDI of all the studied elements was estimated on the basis of a calculation of the amount of beef consumed by Serbian households (mean beef consumption of 17.2 g/person/day). The studied beef cuts pose no risk with respect to the EDIs of Mn, Se, Cu and Zn. Among the four studied beef cuts, shoulder had the highest content of dietary zinc (68.2 mg/kg).

54 samples belonging to 23 herbal species (15 individuals and 8 mixtures) were analyzed for their contents of heavy metals in the raw materials and in their water infusions. Trace and toxic elements in these samples were determined by using inductively coupled plasma-atomic emission spectrometry (ICP-OES) following acid digestion. The order of decreasing mean metal concentrations in raw materials (mg/kg) was found to be as follows: Fe (440) > Mn (162) > Zn (45.8) > Cu (12) > Pb (10.4) > Ni (5.4) > Cr (2.9) > Co (0.91) > Cd (0.5). It was found that 21% of the analyzed samples contain both Cd and Pb above their permissible limits. However, the infusions produced from these plants were found to contain fewer amounts of metals than the raw materials. Studied metals had the following mass transfer percentages to the infusion solutions (Fe: 3.5%, Cd: 14%, Cr: 15%, Pb: 20%, Co: 29%, Ni: 31%, Zn: 36%, Cu: 48%, and Mn: 53%). The estimated daily intake calculated for the toxic elements Pb and Cd through the consumption of herbal infusions was far below the tolerable daily intake set by the World Health Organization (WHO).
