Introduction: Radicchio (Cichorium intybus L.) is a leaf chicory and is grown as a leaf vegetable which usually has white-veined red or purple leaves and it belongs to the Asteraceae family. In several countries is consumed mainly as salad, but no studies on their elemental composition  has been done, principally in Brazil. Objective: The aim of present work was to measure the macroelements (Na, K, Ca, Mg and P) and microelements (Cr, Cu, Fe, Mn, Mo, Zn, Al, Cd, Ni, Co and Si) in the leaf Chicory used as human nourishment in the Campo Grande, State of Mato Grosso do Sul, Brazil. Method: Chemical digests of samples were prepared using HNO3 and H2O2 and then placed in the microwave digestion system. After digestion, the concentrations of the elements in Leaf Chicory were determined by the technique of Inductively Coupled Plasma - Optical Emission Spectrometer (ICP–OES, Thermo Scientific - iCAP 6000 Series). Results obtained of the concentrations of leaf chicory were compared with the dietary reference intakes. Results: Detected concentration of macroelements in leaf Chicory decreases in the order: K > P > Ca > Mg > Na. As well as the concentration of microelements decreases in the order: Fe > Al > Si > Mn > Zn > Cu > Cr > Ni > Cd > Mo > Co. Leaf Chicory is excellent source of K, Ca, Mg, P, Cr, Cu, Fe, Mn, Mo and Zn for children and adults. On the other hand, leaf chicory is not considered a source of sodium for children and adults. Concentration of K, Cr, Fe, and Al are above the limit recommended limit by FAO/WHO (1984) and others countries. Conclusions: Leaf Chicory has macro and microelements in ample amount; it can be used as an important part of people's diets. Since it not exceed allowable limits set by WHO and FAO, RDA/AI and UL. Competent organs have not evaluated concentrations of elements as Al, Cd, Ni, Co and Si in order to establish a tolerable upper intake level or RDA/AI for human. The lack of studies of adverse effects following excess intake of a nutrient does not mean that adverse effects do not occur. Keywords: Leaf Chicory; Radicchio; Inductively Coupled Plasma Mass Spectrometry (ICP-OES).

Introduction: The Synadenium grantii Hook species is a medicinal plant of the Euphorbiaceae family and is popularly known in the Midwest regions of Brazil as leitosinha or janaúba. All the parts of Synadenium grantii Hook as stem, latex, leaves and flowers are used for the treatments of various disease, but no elemental composition has been done. Objective: The aim of present work was to measure the macroelements (K, Mg, Mo and P) and microelements (Cr, Cu, Fe, Mn, Mo, Zn, Si, Ni, Co, Cd and Al) in the leaves of medicinal plant Synadenium grantii Hook used in the treatment of diseases by rural and urban communities of the Campo Grande, State of Mato Grosso do Sul, Brazil. Method: The chemical digestions of samples were prepared utilizing HNO3 and H2O2 and microwave digestion system Speedwave Berghof, Germany. After digestion, the concentrations of the elements in leaves were determined by technique of Inductively Coupled Plasma – Optical Emission Spectrometer (ICP-OES) with a Dual Plasma (Thermo Scientific – iCAP 6000 Series) Results: Results demonstrated that the Synadenium grantii leaves are source of K but aren't the best source of Na and P. Its leaves are rich in elements such as Mg, Cr, Cu, Fe, Mn, Mo and Zn. The leaves of Synadenium grantii showed a high content of Mg values tolerable upper intake level. However, Fe, Na, P, Mn, Mo and Zn are below the values tolerable upper intake level. The leaves of this plants have elements as Ni, Cu, Cr, Cd above the permissible limit set by WHO and FAO. Conclusions: The gaps in knowledge about the level of contents in the Synadenium grantii was completed in this work and would serve as a tool for deciding the dosage of prepared from this plant with medicinal and nutritional purposes. Brazil should create legal standards for the use of medicinal plants based on internationally practiced requirements. Keywords: Medicinal plants, Synadenium grantii, inductively coupled plasma mass spectrometry.

Abstract The objective of the present study was to investigate selected trace and mineral elements in Royal Jelly (RJ) from Bulgaria. A total of 30 RJ samples were included in the study. The analytical procedure consisted of the microwave digestion of the RJ samples with nitric acid followed by instrumental measurement. Concentrations of Al, Ba, Ca, Cr, Cu, Fe, K, Mg, Mn, Na, P, Sr and Zn were determined using inductively coupled plasma optical emission spectroscopy (ICP-OES), while As, Cd, Co, Ni and Pb were determined by electrothermal atomic absorption spectrometry (ETAAS). Our results showed that elements K, Mg, Ca represented 96% from the total mineral content of the RJ samples from Bulgaria, while the most abundant trace element was Na, followed by Zn. The elements Ba, Cr, Cu, Fe, Mn and Sr were found in trace concentration levels and elements As, Pb, Cd, Co and Ni in microconcentration levels. Selected mineral and trace elements were found in relatively constant concentration levels in all of the analyzed RJ samples. It was concluded that chemical element content did not depend on geographical origin and was under homeostatic adjustment in RJs.

AbstractCurrently, the quantitative analysis methods for uranium that are widely used in laboratories, such as the volumetric method and inductively coupled plasma mass spectrometry (ICP-MS) cannot achieve low cost, simple operation, and little influence by other elements. The inductively coupled plasma optical emission spectrometer (ICP-OES) has a wide linear range, and high stability, and can be used to identify multiple elements simultaneously. However, when ICP-OES is used for quantitative analysis of uranium, the settings for the RF power, nebulizer flow, and pump rate can affect the analysis results. In this work, these parameters were carefully optimized for identifying uranium. Based on experiments, we selected two spectrum peaks 409.014 nm and 424.167 nm for quantitative analysis with the lowest interference. The optimal parameters obtained are atomizer flow rate of 0.75 L/min, a sample pumping rate of 1.6 mL/min, and a high-frequency power of 1400 W. Then we compared the accuracy of the volumetric method, ICP-MS method and ICP-OES method with the optimized parameter for analysis of experimental samples and references. The results showed that the ICP-OES with the optimized parameters proposed in this paper can be used to perform a convenient, quick, and efficient quantitative analysis of uranium in minerals.

Abstract: The concentration of heavy metals (Cr, Fe, Al, As, Cd, Cu, Pb, Mo, Ni, Se and Zn) was evaluated in the blood of nestling blue macaws (Anodorhynchus hyacinthinus) captured in the Pantanal, Mato Grosso do Sul (n=26) in 2012; this was based on the hypothesis that these birds exhibit levels of these heavy metals in their organism and that these interfere in hatching success, weight and age of the chicks. Blood samples were digested with nitric acid and hydrochloric acid and the quantification of metals was performed by ICP-OES (Optical Emission Spectroscopy and Inductively Coupled Plasma). Blood samples of nestlings showed concentrations of Cr (0.10μg/g) Fe (3.06μg/g) Al (3.46μg/g), Cd (0.25μg/g) Cu (0.74μg/g), Mo (0.33μg/g), Ni (0.61μg/g), Se (0.98μg/g), and Zn (2.08μg/g). The levels of heavy metals found were not associated with weight, age and hatching success of the chicks.
