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.

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.

This study compared the ability of the lichen Evernia prunastri, chitin and chitosan to take up Cu2+ and Zn2+. It was hypothesized that chitin and chitosan have an accumulation capacity comparable to the lichen, so that these biopolymers could replace the use of E. prunastri for effective biomonitoring of Cu and Zn air pollution. Samples of the lichen E. prunastri, as well as chitin (from shrimps) and chitosan (from crabs), were incubated with Cu and Zn solutions at concentrations of 0 (control), 10, 25, 50, 75, and 100 µM and analyzed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Metal concentrations accumulated by lichen, chitin and chitosan samples were strongly and linearly correlated with the concentrations in the treatment solutions. The lichen always showed significantly higher accumulation values compared to chitin and chitosan, which showed similar accumulation features. The outcomes of this study confirmed the great effectiveness of the lichen Evernia prunastri for environmental biomonitoring and showed that chitin and chitosan have a lower accumulation capacity, thus suggesting that although these biopolymers have the potential for replacing E. prunastri in polluted areas, their suitability may be limited in areas with intermediate or low pollution levels.

AbstractThe historic Waterberg platinum deposit, ~15 km WNW of Mookgophong (formerly Naboomspruit), Limpopo Province, South Africa, is a rare fault-bound hydrothermal vein-type quartz-hematite-platinum-group mineralization. As a continuation of the geochemistry and ore mineralogy studies (Part I, Oberthür et al., 2018), this paper concentrates on the ore-bearing quartz and on the age constraints of ore formation. The state-of-the-art methods used include cathodoluminescence microscopy, electron probe microanalysis (EPMA) and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) of trace elements, stable isotope (δ18O) analysis and fluid-inclusion studies. U-Pb and (U-Th)/He radiometric age determination gave ages of 900–1075 Ma suggesting platinum-group element (PGE) mineralization as a result of upwelling fluids with connection to the Bushveld complex during Kibaran tectonic movements along the Thabazimbi–Murchison Lineament. Felsic fragments containing Qtz-1 were cemented by different quartz generations (Qtz-2 to Qtz-4) and enable the characterization of the changing physicochemical parameters during multistage mineralization and cooling. The PGE minerals are associated with the earliest hydrothermal stage represented by botryoidal radial-fibrous quartz aggregates (Qtz-2a) which formed on brecciated felsite. The other quartz types are essentially barren. Cathodoluminescence studies of quartz indicate very high Al, Fe and K concentrations as confirmed by EPMA and LA-ICP-MS, whereas Ti is always very low. The varying Al concentrations in the quartz mainly indicate pH fluctuations, the high Fe3+ points at high oxygen fugacity. Micro-inclusions of iron oxide are associated with Pt ore (Fe, Pt, Pd, Au, W, Sb, As), rutile, kaolinite and muscovite. The hydrothermal activity must have been characterized by low saline (<10 wt%) H2O–NaCl solutions. These fluids mixed with original high-saline NaCl ± CaCl2 ± CO2 brines in the brecciated felsite (Qtz-1). According to the quartz-hematite geothermometer the ore depositional temperatures were ~370–330°C (Qtz-2a), whereas the successive quartz veins formed during cooling towards ~295°C. The transport of PGE must have been facilitated by strongly oxidizing chloride complexes of relatively low salinity and moderate acidity.

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.

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.

Abstract Heavy metals are unique environmental and industrial pollutants scattered naturally and found almost in all phases of the environment. In certain limited areas in several parts of the world, many people and animals have suffered from several severe diseases caused by trace elements or heavy metal deficiencies and their toxicities, unaware of their existence. The compounds of Pb and Cd are classified as human carcinogens by numerous regulatory agencies. The soil samples digested using the aqua regia method, and concentration quantified through the Inductively coupled plasma mass spectrometry (ICP-MS). In this study, Pb, Cd, and Hg concentrations were recorded high on the landfill site compared to the control site. Their concentration exceeded the permissible limits from WHO. Pb concentration ranges between 0.46ppm to 1.81ppm, Cd range from 0.98ppm and 0.56ppm, and Hg has a high concentration that varies between 6.28ppm and 1.69ppm. On the contrary, the Cu concentration reportable to be lesser than accepted WHO limits compared to the other two selected elements. The mean concentration of Cu ranges from 0.41 ppm to 0.72 ppm. Soil pH for both sites ranged from slightly acidic (6.67) to neutral (7.09), which falls within the normal range suggested by WHO. High Hg and Pb concentration in this study is a thing of concern. Undertaken this study to help address the soil pollution problem due to the illegal disposal of waste that results in metal accumulation.
