ABSTRACTThe effects of trace contents of 15 elements in the sedimentary rocks on the Rs- and Rd-values (Maass, 1983) of the dissolved radionuclides of the elements C (as carbonates), Se, Sr, Tc, I, Cs, Pb, Ra, Ac, Pa, U, Np, Pu, Am. and Cm were investigated and discussed. For this purpose Sr, Ba, B, Corg., Pb, P, F, Cu, Zn, Cd, V, Mn, Fe, Co and N1 contents in the rocks were compared to the sorptlon/desorption coefficients of the above mentioned 15 radionuclides and plotted in x-y diagrammes (a total of 225). While the magnitude of most trace element contents has no or only a slight influence on the retention properties of most radionuclides, a distinct correlation between the trace element contents and the magnitude of the distribution coefficients was found for some radionuclides. Particularly copper, organic carbon, and barium are found to take a positive influence on the Rs-/Rd-values of certain radionuclides. The presence of other trace elements (eg. B and F) can have a negative effect on the retention behaviour of the rock matrix as regards certain dissolved radionuclides. Seen as a whole, the magnitude of the desorption coefficients (Rd-val-ues) appears to be more closely correlated to the trace element contents than to the sorption coefficients (Rs-values).

In this paper, the characteristics o f trace metal elements were studied in Elsholtzia harchowensis. The relation of trace elements between plant and soil was studied, and the copper tolerance and mechanism of the plant was discussed in details. The results showed that the trace element contents of the soil was higher, Cu content was highest in these elements, and it was as more 200 times as that of control sites. Cu in the plant was highest in these elements and Cd was lowest. The elements sequence in plant was: Cu> Mn> Zn> Pb> Cd. Element contents in different parts of the plant were: Cu, root> flower> leaf> stem; Cd, leaf> flower> root> stem; Mn, leaf> root > flower> stem; Zn, leaf> flower> stem> root; Pb, root> leaf> stem> flower. There is positive correlation in Cu between plant and soil. The tolerance capacity is higher in the plant.

There are hundreds of years old wild sweet chestnut trees grown among alder, hornbeam, and pine etc. trees in natural forest of Giresun/TURKEY. In this study, trace element contents of chestnuts collected from chestnut trees in these natural forests were investigated. For this purpose, A total of eight elements, manganese (Mn), iron (Fe), zinc (Zn), nickel (Ni), cobalt (Co), selenium (Se) and lead (Pb) were determined by Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) in chestnut samples collected from ten chestnut trees. The content of trace elements was determined separately in fruit, bark and pellicle parts of chestnut. In chestnut fruit samples, highest concentration values in mg kg-1 of Mn, Fe, Zn, Ni, Cu, Se, Co and Pb are: 88.29, 72.96, 27.76 8.25, 7.81, 2.28, 0.056 and 0.043 respectively. Chestnut bark has been shown the highest values as Mn 176.01, Fe 96.55, Zn 26.97, Ni 4.33, Cu 8.91, Se 3.08, Co 0.089 and Pb 0.058 mg kg-1. The highest concentrations of trace elements in chestnut pellicle are found as Mn 176.26, Fe 92.98, Zn 60.06, Ni 5.79, Cu 11.4, Se 3.29, Co 0.135 and Pb 0.095 mg kg-1. These results suggest that natural chestnuts grown in the Giresun region are quite rich nutrients in terms of trace element contents.

Wastewater Samples

Assessment the effect of industrial wastewater on the yield and trace element contents of red amaranth was carried out by this study. Thirty wastewater samples were collected from five major environment-polluting industries namely pharmaceuticals, dyeing, leather, food, and plastic industries at three different locations. Atomic Absorption Spectrophotometer was used for analyzing the trace elements in the wastewater-irrigated samples of red amaranth. Higher mean concentrations of Pb, Cd, Ni, Cr, As, Zn, and Cu in red amaranth were 0.97, 0.20, 1.23, 52.72, 0.52, 0.85, and 2.62 ?g g-1. The percentage of yield reduction in red amaranth were 11.06, 12.73, 14.07, 3.46, 7.82 % for T2, T3, T4, T5 and T6 respectively compared to distilled water control (T1). The results concludes that the wastewater samples of pharmaceuticals, dyeing, leather and plastic industries were more polluted than the wastewater of food industries. Vegetables grown in industrial areas contain trace elements viz. Cr, Ni and Cu which would be health hazardous for consumer.J. Environ. Sci. & Natural Resources, 9(2): 27-30 2016

Background: Thyroid cancer is an internationally important health problem. The aim of this exploratory study was to evaluate whether significant changes in the thyroid tissue levels of Ag, Co, Cr, Fe, Hg, Rb, Sb, Sc, Se, and Zn exist in the malignantly transformed thyroid. Methods: Thyroid tissue levels of ten trace elements were prospectively evaluated in 41 patients with thyroid malignant tumors and 105 healthy inhabitants. Measurements were performed using non-destructive instrumental neutron activation analysis with high resolution spectrometry of long-lived radionuclides. Tissue samples were divided into two portions. One was used for morphological study while the other was intended for trace element analysis. Results: It was found that contents of Ag, Co, Cr, Hg, and Rb were significantly higher (approximately 12.8, 1.4, 1.6, 19.6, and 1.7 times, respectively) in cancerous tissues than in normal tissues. Conclusions: There are considerable changes in trace element contents in the malignantly transformed tissue of thyroid.

AbstractThe proton microprobe has been used to determine contents of Ca, Ti, Ni, Mn and Zn in the olivine of 54 spinel lherzolite xenoliths from Australian and Chinese basalts. These data are compared with proton-probe data for Ni, Mn and Zn in the olivine of 180 garnet peridotite xenoliths from African and Siberian kimberlites. Fe, Mn, Ni and Zn contents are well-correlated; because the spinel lherzolite olivines have higher mean Fe contents than garnet peridotite olivines (average Fo89.6vs. Fo90–92) they also have lower Ni and higher Mn contents. Zn and Fe are well-correlated in garnet peridotite olivine, but in spinel peridotites this relationship is perturbed by partitioning of Zn into spinel. None of these elements shows significant correlation with temperature. Consistent differences in trace-element contents of olivines in the two suites is interpreted as reflecting the greater degree of depletion of Archean garnet peridotites as compared to Phanerozoic spinel lherzolites. Ca and Ti contents of spinel-peridotite olivine are well correlated with one another, and with temperature as determined by several types of geothermometer. However, Ca contents are poorly correlated with pressure as determined by the Ca-in-olivine barometer of Köhler and Brey (1990). This reflects the strong T-dependence of this barometer: the uncertainty in pressure (calculated by this method) which is produced by the ±50°C uncertainty expected of any geothermometer is ca ± 8 kbar, corresponding to the entire width of the spinel-lherzolite field at 900–1200°C.
