“…The results for groundwater samples exceeded European primary drinking water standards for Fe (>200 μg/l) and Mn (>50 μg/l), while the levels of the trace metals are below the thresholds for drinking water quality were taken within the Pančevo Oil Refinery (Serbia) [3]. Concentrations of trace metals were found (mg/kg) to be for Mn: 656, Fe: 26734, Ni: 32.3, Zn: 72.8, Pb: 13.4 and Cu: 27.0. within an oil refinery Pančevo (Serbia) [4]. Results from Venezuela in the area of largest oil refinery complex indicated that levels of pollution of particular contaminants such as Hg, Pb, Cd and TPH in sites close to the oil refineries that have been operating in the area for decades are above local and international recommended standards [5].…”

The aim is to evaluate the exposure of Slavonski Brod citizens to metals from the environment: lead, cadmium, mercury, arsenic, nickel, manganese and thallium. Concentrations of Pb, Cd, Hg, As, Ni, Mn and Tl were analyzed in the whole blood and/or serum, urine and hair of 40 examinees from Slavonski Brod. According to "wind rose" data and the vicinity of the oil refinery, examinees were divided in two groups: Group I with 20 examinees (17 females/3 males) and Group II with 20 examinees (13 females/7 males). Metals were analyzed using inductively coupled plasma mass spectrometry. Analysis accuracy was confirmed with reference samples. The difference between the groups was tested using the Mann-Whitney U test. Reference values were taken from German commission for biomonitoring, biomonitoring studies with Canadian examinees, Mayo Medical Laboratories reference values, USA and London Pathology, and Laboratory Medicine from Canada. There was no difference in age between the groups (Group I: x = 48.2; SD ±15.2; Group II: x = 50.7; SD ± 21.7; z = -0.590; p = 0.555). Statistically significant differences were determined in As in blood In Group I, one patient had elevated cadmium in hair (0.227 µg/g), the second had elevated arsenic in urine (78.73 µg/L), the third had elevated mercury in blood (16.53 µg/L) and hair (2021 µg/kg); in Group II, one had elevated lead in urine (6.88 µg/L) and hair (8.39 µg/g), the second had elevated cadmium in urine (3.11 µg/L), the third had elevated cadmium in blood (2.98 µg/L), the fourth had elevated lead in blood (171.9 µg/L) and urine (20.1 µg/L), and the fifth had elevated lead in urine (10.01 µg/L). The conclusion of this study is that the differences between the two groups are within referent values and this study should be expanded with more subjects and more parameters.

“…Relić et al [20] applied HCA to sequential extraction data for river sediments, but they made few comments to the dendrogram and mainly discussed the results considering PCA and correlation analysis (Part I) [9]. They observed some analogies between the associations of variables in the dendrogram and in PCs.…”

“…The results of this techniques have been used for several purposes: i) to distinguish among sources of elements [10,19]; ii) to identify zones with different pollution levels within a contaminated site [15][16][17]24 ]; iii) to study the chemical behaviour of main properties and element fractions [12,14,20,23]; iv) to study soil-plant relationships [11,18]; v) to distinguish soils from different areas [22] or the variations of chemical composition along a sediment core [13]; vi) to evaluate the characteristics of extractants [21]; vii) to better interpret the results of PCA [25] or compare the performances of different algorithms [26]. Examples of these applications are discussed hereafter.…”

The role of calcium (Ca) in the cycle of phosphorus in water environment depends on the speciation of Ca in sediments, and reliable Ca sequential extraction method is useful for obtaining information about Ca transport processes from sediment to water. Experiments have been carried out to develop a simple but robust Ca sequential extraction method for identification of Ca portioning in sediments. The sequential extraction protocol was modified for extractants, extracting time, concentration and pH of the reagents in the first three steps of Tessier sequential procedure. With optimum conditions, there were 1:25 sediment to solution ratio and 3 h of extracting time shaken with NH 4 AC (1 mol L -1 , pH 7.0) (exchangeable Ca fraction); 1:25 sediment to solution ratio and extracted with NH 4 AC (1 mol L -1 , pH 5.0) for 5 h (carbonatebound Ca fraction); and 1:30 sediment to solution ratio and extracted with NH 2 OHÁHCl (0.5 mol L -1 , pH 1.5) for 6 h (Fe and Mn oxides bound Ca fraction). The recovery for Tessier procedure ranged form 35.6 to 71.1 %, while the recovery for the modified Tessier procedure ranged form 46.1 to 86.9 %. These results revealed that Tessier procedure underestimated the proportion of Ca in exchangeable fraction. In sediments, Ca was mainly exchangeable and carbonate bound, which was considered as the most liable fractions.
