This study was conducted to analyze the effect of molybdenum (Mo) on the level of macronutrients (Mg, K, Ca), micronutrients (Na, Zn, B, Mo, Mn, Fe, Co, Ni, Cu) and toxic elements (Cd, Sn, As, Cr, Hg, Pb) in leaves and fruit tissues (peel, pulp & seed) of loquat using inductively coupled plasma-mass spectrometry (ICP-MS). Fruits were obtained from a loquat orchard located in Fujian (Yun Xiao/Zhangzhou). Loquat leaves showed 3.99, 23.90, 57.68 and 9.79-fold increase in the concentrations of Mg, K, Ca and B as affected by exogenously applied Mo, while a significant (p ≤ 0.05) reduction was observed in Na, Mo, Mn, Co, Ni, Cu, Sn, As, Cr, Hg, and Pb contents. In fruit peel, Mo induced 1.05, 1.56, 2.26, 1.15, 1.39, 1.30 and 1.89-fold increase in Mg, K, Na, Zn, B, Co and Ni, respectively, and Mo, Mn, Fe, Cu, Cr, and Pb contents were reduced. Fruit pulp showed elevated contents of Na, B, Co, Ni, and Sn by 25.65, 26.57, 70.09, 12.33 and 0.99%, respectively, and decreased concentrations of Mg, K, Ca, Zn, Mo, Mn, Fe, Cu, Cd, and Cr. Similarly, in loquat seeds, under the influence of Mo application, levels of K, Na, Zn, Fe, and Cr were uplifted by 14.75, 41.54, 12.71, 536.47 and 656.27%, respectively, while Mg, Ca, Mn, Co, Cu, Sn, and Hg were reduced significantly (p ≤ 0.05). Overall, mineral concentrations detected in the leaves and fruit tissues of loquat were greatly influenced by the application of Mo. Although the concentration of Sn in fruit pulp was increased by the foliar application of Mo, the fruits were under safe limits for human consumption.

This study was conducted to analyze the effect of magnesium (Mg), zinc (Zn) and boron (B) on the level of macronutrients (Na, Mg, K, Ca), micronutrients (Zn, B, Mo, Mn, Fe, Co, Ni, Cu), and heavy metals (Cd, As, Hg, Pb) in loquat leaves and fruit tissues (peel, pulp, and seed) using inductively coupled plasma-mass spectrometry (ICP-MS). Fruits were obtained from a loquat orchard located in Fujian (Yun Xiao/Zhangzhou). The results revealed that the foliar application of Mg increased the concentrations of Mg, K, Ca, Zn, B, Mn, Ni, and Cu in leaves; Mg, Ca, Zn, B, Mo, and Mn in fruit pulp; and Na, K, B, Mo, Co, Ni, and Cu in seeds. Zinc increased Mg, K, Ca, Zn, B, Ni, and Cu in leaves; Fe, Co and Ni in fruit peel; K, B, Mn, Fe, and Co in fruit pulp; and Na and K in seeds. Similarly, B application increased the concentrations of Na, Mg, K, Ca, and B in leaves; Ca and Ni in fruit peel; Na, Mg, Ca, Zn, B, Mn, Fe, and Co in fruit pulp; and Na, K, Ca, Zn, B, Mo, Mn, Co, and Ni in loquat seeds. Overall, mineral concentrations detected in the leaves and fruit tissues of loquats were greatly influenced by the application of Mg, Zn and B. Although heavy metal concentrations in fruit pulp were increased by the foliar application of B, the fruits were under safe limits for human consumption.

This study aimed at analyzing the content of 10 toxic elements (Be, Al, Ti, As, Cd, Sn, Sb, Hg, Pb and Ag) in different tissues (leaf blade, seed, fruit peel and pulp) of loquat fruits, at different maturity stages (immature green, mature green and full ripe) from Fujian (Yun Xiao/Zhangzhou) in China, using inductively coupled plasma-mass spectrometry (ICP-MS), with microwave digestion. Results revealed that the concentrations of Be, Al and Hg in all observed tissues were significantly reduced with the change in maturity of fruits from immature green to full ripe. Whereas the toxicity of Ti, As, Cd, Sb and Pb were observed to be shifted from seed and pulp to peel and leaves. Tin concentration was increased in all observed tissues except seeds, while silver concentration was only increased in fruit peel of loquat. In sum up, toxic elements concentration detected in the fruit pulp of loquat, at full ripe stage, was found safe for human consumption.

Mining activities at the upstream of the Kuantan River basin can be resulted to adverse impacts for both human and aquatic lives. The heavy metal contamination of aquatic environment has gained the public attention. In fact, in recent decades, urban activities and industrial waste have led to an increase in contamination of heavy metals in the water bodies which may have direct effect on aquatic ecosystem. Therefore, this study aims to determine the level of Aluminium (Al) and Copper (Cu) in the muscle and gills of giant freshwater prawns (Macrobrachium rosenbergii) collected from five selected rivers in Kuantan, Pahang. Field sampling was conducted between September and December 2017. The giant freshwater prawns were digested and then analysed with inductively coupled plasma-mass spectrometry. The obtained results revealed that, Al levels in muscle of M.rosenbergii among all rivers occurred in the rank order: Pandan river>Riau river> Pinang river> Kuantan>Balok river, while in gills: Pandan river>Kuantan river>Balok river>Pinang river>Riau river. The concentration of Cu in muscle were in order of: Pandan river>Pinang river> Riau river> Balok river > Kuantan river, whereas Cu in gills were: Pandan river>Balok river>Kuantan river>Pinang river > Riau river. The highest content level of Al and Cu in both prawn’s muscle (14.03 ± 3.55 and 12.28 ± 3.87) mg/kg and gills (7.06 ± 2.53 and 12.28 ± 3.87) mg/kg were caught from Pandan River. In risk and safety assessment, the metal concentrations in the edible muscle of prawn were found to be below the established limits by WHO (1982), MFA (1983, US FDA (2001), and JECFA (2000). This study suggests that the prawns caught from Kuantan river are safe for human consumption.

Abstract Honey is a common sweetener in the Jordanian diet with annual consumption of about one thousand tons, two-third of them are imported. It is believed that the elemental profile of honey is an indicator of safety and origin. In the literature, there is a lack of studies concerning levels of trace elements in honey in Jordan. A total 49 elements including 18 rare earth elements (REEs) were analyzed by inductively coupled plasma-mass spectrometry (ICP-MS) in mono-floral, and multi-floral imported honey samples, and multi-floral local samples. Regarding mono-floral samples, Black forest samples has the highest total metal content, while Acasia has the lowest total metal content. Local multi-floral honey has the largest Sr, and total REEs levels, while it has the lowest Mn levels. Very low levels of toxic elements were found in all samples, indicating the safety of honey in Jordan for human consumption. Results of this study showed that advanced statistical models are required to discriminate between multi-floral imported and local honey.

Major dependence on wheat-based foods with low bioavailability of nutrients led to high malnutrition rates, especially in developing counties. Four wheat genotypes (Albelad (BE), Aldwasair (AD), Australia (AU) and Najran (NJ)) grown in Albaha region were analyzed for the first time for the variation in micronutrient (Se, Mo, Cu, Zn, Mn, Fe, B and Na) and macronutrient concentrations (P, Ca, Mg and K) in the whole wheat grain using Inductively coupled plasma mass spectrometry (ICP-MS) in order to select genotype of high nutritional value of the wheat for human consumption for further breeding by farmers. Substantial micronutrient variation existed among the four genotypes according to their mean Se, Mo, Zn, and Na concentrations, while macronutrient variation existed in their P and Ca concentrations. The NJ genotype appeared to contain higher concentrations of Se, Na, and Ca than the other genotypes while AU contained higher concentrations of Zn and P than AD, BE, or NJ. The results of this study can provide information about micro- and macro-nutrient enriched wheat genotypes for agricultural strategies aimed at improving the nutritional value of wheat plants.

Textural Evidence

ABSTRACTThe Fen Complex in Norway consists of a ~583 Ma composite carbonatite-ijolite-pyroxenite diatreme intrusion. Locally, high grades (up to 1.6 wt.% total REE) of rare-earth elements (REE) are found in a hydrothermally altered, hematite-rich carbonatite known as rødbergite. The progressive transformation of primary igneous carbonatite to rødbergite was studied here using scanning electron microscopy and inductively coupled plasma-mass spectrometry trace-element analysis of 23 bulk samples taken along a key geological transect. A primary mineral assemblage of calcite, dolomite, apatite, pyrite, magnetite and columbite with accessory quartz, baryte, pyrochlore, fluorite and REE fluorocarbonates was found to have transformed progressively into a secondary assemblage of dolomite, Fe-dolomite, baryte, Ba-bearing phlogopite, hematite with accessory apatite, calcite, monazite-(Ce) and quartz. Textural evidence is presented for REE fluorocarbonates and apatite breaking down in igneous carbonatite, and monazite-(Ce) precipitating in rødbergite. The importance of micro-veins, interpreted as feeder fractures, containing secondary monazite and allanite, is highlighted. Textural evidence for included relics of primary apatite-rich carbonatite are also presented. These acted as a trap for monazite-(Ce) precipitation, a mechanism predicted by physical-chemical experiments. The transformation of carbonatite to rødbergite is accompanied by a 10-fold increase in REE concentrations. The highest light REE (LREE) concentrations are found in transitional vein-rich rødbergite, whereas the highest heavy REE (HREE) and Th concentrations are found within the rødbergites, suggesting partial decoupling of LREE and HREE due to the lower stability of HREE complexes in the aqueous hydrothermal fluid. The hydrothermal fluid involved in the formation of rødbergite was oxidizing and had probably interacted with country-rock gneisses. An ore deposit model for the REE-rich rødbergites is presented here which will better inform exploration strategies in the complex, and has implications for carbonatite-hosted REE resources around the world.

Mn Concentrations

Deficiency or excess exposure to manganese (Mn), an essential mineral, may have potentially adverse health effects. The kidneys are a major organ of Mn site-specific toxicity because of their unique role in filtration, metabolism, and excretion of xenobiotics. We hypothesized that Mn concentrations were associated with poorer blood pressure (BP) and kidney parameters such as estimated glomerular filtration rate (eGFR), blood urea nitrogen (BUN), and albumin creatinine ratio (ACR). We conducted a cross-sectional analysis of 1931 healthy U.S. adolescents aged 12–19 years participating in National Health and Nutrition Examination Survey cycles 2013–2014, 2015–2016, and 2017–2018. Blood and urine Mn concentrations were measured using inductively coupled plasma mass spectrometry. Systolic and diastolic BP were calculated as the average of available readings. eGFR was calculated from serum creatinine using the Bedside Schwartz equation. We performed multiple linear regression, adjusting for age, sex, body mass index, race/ethnicity, and poverty income ratio. We observed null relationships between blood Mn concentrations with eGFR, ACR, BUN, and BP. In a subset of 691 participants, we observed that a 10-fold increase in urine Mn was associated with a 16.4 mL/min higher eGFR (95% Confidence Interval: 11.1, 21.7). These exploratory findings should be interpreted cautiously and warrant investigation in longitudinal studies.

The Rietspruit is located in Gauteng Province, South Africa, within the Witwatersrand Basin. The basin is noted for its vast gold deposit. The river extends for about 60 km before joining the Vaal River. The aim of this study was to determine the concentration of uranium in the Rietspruit and the factors that influenced the concentration of U at each of the sites. The source of uranium in the river is the discharge from the gold mine and the mine wastes. Inductively coupled plasma mass spectrometry was used for water and sediment analysis in order to determine the concentration of U. High concentration of U was found in the river water and sediment, which is above the permissible limit of U. The water is used for irrigation of farmlands, cattle watering and for human consumption despite the high concentration of uranium in it. Ingestion of uranium is dangerous to human health. Due to the toxic nature of uranium, consumption of the water for domestic use and agriculture purpose must be discouraged.
