A total of 65 uncultivated surface soils samples from the area surrounding the city of Kavala, Northern Greece, was collected and analyzed for their abundance in 22 trace elements. The extraction of the elements from the < 200μm soil fraction was based on the digestion of 0.1 g of each sample with 2 ml HNO3. The analytical methods used were ICP-OES and ICP-MS and the elements analyzed were Ag, As, B, Ba, Cd, Co, Cr, Cs, Cu, Hg, Μη, Mo, Ni, Pb, Sb, Se, Sn, Sr, Ti, V, W, and Zn. The chemistry of the surrounding rocks and mineralizations has mainly affected the trace elements contents of the surface soils samples. The average elemental concentrations of the 65 uncultivated surface soil samples were compared with the average values for normal soils of the USA. Arsenic, Pb, andZn were found to be enriched in the surface soils of the present study by a factor of 7.6, 3.3, and 2.7, respectively, indicating that human activities have contributed to their enrichment, since these elements are strongly connected to the industrial and agricultural activities in the area.

A total of 65 surface soils and 8 rock samples from the area surrounding the city of Kavala, Northern Greece, was collected and analyzed for their contents in 10 major and 32 trace elements. The extraction of the elements from the < 200μm soil fraction was based on the digestion of 0.1g of each sample with 2ml HNO3. The analytical methods used were ICP-OES and ICP-MS and the elements determined were Al, Ca, Cl, Fe, K, Mg, Na, P, S, Si, Ag, As, B, Ba, Cd, Ce, Co, nCr, Cs, Cu, Ga, Ge, Hg, La, Li, Mn, Mo, Ni, Pb, Rb, Sb, Se, Sn, Sr, Th, Ti, U, V, W, Y, Zn and Zr. Comparisons between the concentrations of the surface soil samples and the surrounding rock samples indicate that the majority of major, as well as, of trace elements are found in the surface soils of Kavala with such concentrations that are considered as the product of natural processes such as the weathering of parent rocks and pedogenesis. However, there are some nmajor elements (Cl, Na, S) and trace elements (Ag, As, Pb, V, Zn) that are present in the surface soils of the study area with elevated concentrations that cannot be regarded as the sole product of natural processes, but as the result of both, natural and anthropogenic activities, especially for the samples that are situated inside the industrial area of Kavala.

Abstract This paper reports the results of trace elements geochemistry from Tigray national state, northwestern Ethiopia. The area is part of the Arabian-Nubian Shield, where the dominant exposure is low-grade metamorphic rocks and has a long history of liver-related diseases. The increase in the number of liver-related disease patients of the area has been an environmental health issue of national concern. The aim of the study is to determine the level of trace element concentrations and distributions in water and stream sediments of the area and identify the possible sources in relation to human health. Water, stream sediment and rocks samples (20 water, 20 stream sediments, and 6 rock samples) were collected in March 2011 and analyzed for major and trace element contents using ICP-MS, ICP-OES, ion Chromatography, and XRF methods. Bromine, aluminum, fluorine, arsenic, and nitrate values exceed the WHO maximum acceptable concentration (MAC) for drinking purpose. Bromine ranges from 0.11 to 1.48 mg/l show higher values in all samples, and fluorine ranges from 0.21 to 16.49 mg/l show higher values in 20% of the samples. Other trace elements are aluminum—30%, arsenic—10%, and nitrate (NO3)—10%, and they are examples of elements which have above MAC for drinking water. Selenium deficiency may be the other problematic element in the area for which its deficiency is associated with liver damage and heart muscle disorder. The concentration of cobalt and chromium exceeded world geochemical background value in average shale at most sample stations indicated that these stations were in potential risk.

Backgrounds: Variations of trace element contents may be associated with several diseases including metabolic disorders, cellular growth disturbance, mutation and tumorigenesis. Prostate cancer is the second most common male cancer worldwide and stand fifth most common male cancer in Saudi Arabia. Objective: In the present study, Serum levels of selenium, zinc, copper, manganese, and iron were measured in patients with BPH and prostate cancer aiming to explore the association between these elements and prostate cancer. Patients and Methods: The study included 40 newly diagnosed prostate cancer patients, 22 patients with BPH and 30 healthy male subjects. All participant groups had similar socio-economic levels. Fasting blood samples were collected from all subjects and before any intervention for the patients. Serum PSA concentrations were analyzed by ELIZA and trace elements Se, Zn, Cu, Mn and Fe were measured by ICP-MS. Results: Serum Se, Zn, and Mn levels of prostate cancer patients were significantly decreased compared to control groups. The levels of serum Cu and Fe were significantly higher in prostate cancer patients than in control groups. Conclusion: In the present study, an association was noticed between serum trace elements disturbance and prostate cancer. The decreased levels of Se, Zn, and Mn, and increased Cu and Fe levels may play significant roles in the initiation of prostate cancer. However, future prospective studies on the causes of trace elements alteration in prostate cancer patients are needed as well as to illustrate the relation between different prostate cancer stages and trace elements concentrations.

Magnetite is a common accessory phase in various types of ore deposits. Its trace element content has proven to have critical implications regarding petrogenesis and as guides in the exploration for ore deposits in general. In this study we use LA-ICP-MS (laser ablation-inductively coupled plasma-mass spectrometry) analyses of trace elements to chemically characterize magnetite from the Pagoni Rachi Cu–Mo–Re–Au porphyry-style prospect, Thrace, northern Greece. Igneous magnetite mostly occurs as euhedral grains, which are commonly replaced by hematite in fresh to propylitic-altered granodiorite porphyry, whereas, hydrothermal magnetite forms narrow veinlets or is disseminated in sodic/potassic-calcic altered (albite + K-feldspar + actinolite + biotite + chlorite) granodiorite porphyry. Magnetite is commonly associated with chalcopyrite and pyrite and locally exhibits martitization. Laser ablation ICP-MS analyses of hydrothermal magnetite yielded elevated concentrations in several trace elements (e.g., V, Pb, W, Mo, Ta, Zn, Cu, and Nb) whereas Ti, Cr, Ni, and Sn display higher concentration in its magmatic counterpart. A noteworthy enrichment in Mo, Pb, and Zn is an unusual feature of hydrothermal magnetite from Pagoni Rachi. High Si, Al, and Ca values in a few analyses of hydrothermal magnetite imply the presence of submicroscopic or nano-inclusions (e.g., chlorite, and titanite). The trace element patterns of the hydrothermal magnetite and especially the decrease in its Ti content reflect an evolution from the magmatic towards the hydrothermal conditions under decreasing temperatures, which is consistent with findings from analogous porphyry-style deposits elsewhere.

In the present study a total of sixteen samples (3 surrounding rocks and 13 uncultivated topsoils) from the industrial zone east of the city of Kavala, Northern Greece, was collected and analyzed for their content in 41 elements. The extraction of the elements was based on the digestion of 0.1 g of each sample with 2 ml HNO3 and the soil fraction used was the < 20Όμιη. The analytical methods used were ICP-OES for the elements Ca, Mg, Κ, Β, Sr, Fe, Na, Si, S, Ρ, and ΑΙ and ICPMS for the elements Mn, Zn, Cu, Ti, V, Cr, Rb, Ba, Th, La, Ce, As, Sn, Co, Se, Y, Zr, Mo, Cd, Cs, W, Sb, Li, U, Ag, Ni, Hg, Ga, Ge and Pb. The mean element concentrations of the thirteen topsoil samples were compared with the mean values for soil types Fluvisols and Leptosols. The results showed that they are enriched for the elements Ag, As and Pb by 21, 15 and 3 times, respectively. Moreover, the topsoils were compared with the three surrounding rock samples. The results showed that the concentrations of Ca, Mg, Κ, Fe, Si, S, AI, Ρ Na, Β, Ce, Co, Cs, Ga, Ge, Hg, La, Li, Mo, Ni, Rb, Se, Sn, Sr, Th, U and W in the topsoils are mainly influenced by their concentrations in the surrounding rocks. The elements Ag, As, Ba, Cd, Cr, Cu, Mn, Pb, Sb, Ti, Y, V, Zn, and Zr are enriched in the topsoils. The enrichment of Ag, As, Cd, Cr, Cu, Mn, Pb, Sb, and Zn is mainly due to the widespread presence of PBG sulphides, Mn, Cd, and As in the surrounding mineralizations. The enrichment took place, quite possibly, during the formation of Drama and Nestos basins, during Tertiary, and is possibly being continued until today. However, the human activities that take place in the area are also, at least partially, responsible for this enrichment.
