“…The source of Cr may be related to the appearance of Terra Rossa in the surrounding karst area. The term Terra Rossa has been widely applied to red soils overlying limestone and dolomite as a discontinous layer ranging in thickness from a few centimeters to several meters, particularly in Mediterranean region, and Croatian Adriatic Sea coast, as well (Miko et al 1999). Cr abundance in the Terra Rossa matrix is explained as addition from external sources.…”

“…Feng (2011) pointed out that these external additions may be imported by the leaching water from pre-existing surface deposits and bedrock, which could be also partly or entirely eroded away. According to Miko et al (1999), high Cr concentrations in Terra Rossa, but also widely in the region, are due to the polygenetic nature of Terra Rossa (e.g., presence of boehmite). It is possible, therefore, that Cr and Ni could be enriched as a consequence of weathering of karst bauxite deposits, present all along the Coastal Croatia and in karst region of Bosnia and Herzegovina on the north of the study area.…”

Fertile soils in the River Neretva estuary were developed by fluvial sedimentation and deposition of the eroded soil material from the karst hills within the catchment. After extensive reclamation, two reclaimed land zones (fluvial terraces and lower-laying terraces) have been delineated, both used for agriculture. The main objectives of this study were to evaluate soil chemical and geochemical properties in reclaimed zones that differ mainly in topography, soil types and agricultural land use. The origin of the trace metals in the arable soils was studied using multivariate statistics, and interpolation maps of trace metals were produced using GIS and geostatistics. Soil trace metal concentrations do not exceed a threshold value established by the Croatian Government regulation, with exception of copper. Comparative analysis of the main soil properties and trace metal concentrations in the study area showed a pronounced spatial variation and differences between two reclaimed zones in soil organic matter content, bioavailable P and total concentrations of Cd and Cu. Factor analysis in the area of the lower-laying terraces showed grouping of bioavailable P and K, organic matter content and pH (negative loading) in the component associated mostly with the land use. In the area of the fluvial terraces, bioavailable P and total Cd were grouped in the same component that may be explained by the traditional small farm agriculture and overuse of mineral fertilizers. In the whole study area, processes of secondary salinization were determined, accompanied by the raised chloride and sodium concentration measured in the saturation soil extract.

“…The enrichment factor in sediments is widely used in environmental studies and usually relies on the average composition of shale as a baseline and Fe (4.72%) in average shale is also as normalizing element (Turekian and Wedepohl 1961;Trefry and Presley 1976;Sinex and Wright 1988;Slobodan et al 1999;Loska et al 2003;Susana et al 2005). Five contamination categories are recognized on the basis of the enrichment factor (Sutherland 2000): EF < 2 depletion to minimal enrichment, 2 ≤ EF < 5 moderate enrichment, 5 ≤ EF < 20 significant enrichment, 20 ≤ EF < 40 very high enrichment, and EF > 40 extremely high enrichment.…”

The Chaohu is one of the largest five freshwater lakes in China. It provides freshwater for agriculture, life, and part of industry. The quality of water becomes worst and worst due to the toxic matter. In this study, we collected the samples from the sedimentary mud in the lake. The distribution of some potential hazardous trace elements (Cu, Ni, Cr, As, Pb, Cd, and Hg) in the sediments of western Chaohu Lake, has been determined and studied, and the enrichment factors, the index of geoaccumulation, and potential ecological risk were analyzed and calculated. The results show that: the levels of selected potential hazardous trace element vary from different sampling sites and significant anthropogenic impact of Pb and Cd occur in sediments. The contamination rank of Pb and Cd are moderate, and Pb has a light potential ecological risk, but Cd is heavy. The total potential ecological risk of the selected hazardous trace elements in this study in Chaohu Lake is moderate. Cluster and correlation analysis indicate that the selected potential hazardous trace element pollutant has different source and co-contamination also occur in sediments.

Amphorae sherds from the Laecanius workshop of Roman Istria (10-5 B.C. and 78 A.D.), Croatia, were studied by integrating archaeological and geological techniques including fabric analysis, thin-section petrography, X-ray diffractometry (XRD), and heavy mineral analysis. The fabric of the sherds showed distinctive characteristics, permitting their classification and allocation into nine fabric groupss. Petrography revealed that quartz is the dominant clastic component, whereas carbonate is common as temper; XRD provided information on firing temperatures that ranged between 750 and 900°C. The sherds contain diverse heavy mineral suites with generally high epidote and garnet proportions; zircon is occasionally important. Garnet/epidote ratios and the presence of diagnostic species (pyroxene, hornblende) showed systematic variations that coincided with similar variations in fabric characteristics. Heavy mineral signatures of amphorae produced in other workshops proved essential in differentiating them from Laecanius sherds. A comparative heavy mineral analysis of terra rossa samples from the vicinity of the workshop indicated that terra rossa was the major source for the paste. Differences observed in the heavy mineral composition of the sherds and terra rossa were interpreted by the spatial heterogeneity of the latter and the mixing of the paste with sandy temper. Fresh Adriatic sponge spicules in the majority of Laecanius sherds and the temper-derived, generally immature heavy mineral assemblages suggest that sandy deposits from the Adriatic were used for the clastic temper.
