Abstract:The broader Philippi area (NE Macedonia, Northern Greece), which was chosen for the present study, is characterized by the presence of various metals. An approach to the correlation of selected parameters (grain-size distribution, Al 2 O 3 , CaO, Fe 2 O 3 , MnO, SiO 2 content, environmentally available concentrations of Cu and Zn) was carried out in samples collected downstream of Palea Kavala River and Kryoneri and Philippi streams. The abundance of Cu, Fe, Mn, and Zn in relation to four binding fractions (exchangeable, bound to carbonates, Fe-Mn oxides, organic matter complexes) was also investigated. The enrichment of the studied metals was determined by evaluating the enrichment factor (EF) and geo-accumulation index (I geo ). Considering the results, Si was the most abundant major element oxide in sediments, followed by Al, Ca, Fe, and Mn. The sediments are dominated by sand and reveal minor Cu and Fe enrichment and moderate Mn and Zn enrichment. Statistical analyses revealed a significant correlation between Cu, Fe, Mn, and Zn, suggesting their common sources. They probably originate naturally, since the weathering of metal assemblages occurring in the broader Philippi area, comprising minerals such as chalcopyrite, pyrite, goethite, pyrolusite and sphalerite, may contribute to the concentrations of these elements in the sediments.

The aim of the present study was to estimate the geochemical background and anomaly threshold values of the surface soils in Kavala, northern Greece. In order to reach this goal, a simple and practical procedure was applied. This procedure included the extraction of 42 major and trace elements by analytical grade HNO 3 from 65 surface soil samples, analysis by inductively coupled plasma-optical emission spectrometry and inductively coupled plasma-mass spectrometry, the distribution of the elemental data displayed on probability graphs (Q-Q plots), and the visualization of the results spatially by GIS software. The results indicated that natural factors mostly influence the elevated concentrations of Al,

In order to investigate the factors influencing the distribution of 32 potentially toxic elements in the Ptolemais-Kozani basin, northwestern Greece, 38 soil samples were collected and analyzed. Concentrations of Al, and Zn were determined by ICP-AES and concentrations of As, Bi, Cd, Cs, Mo, Rb, Sb, Th, Tl, and U by ICP-MS. Bivariate analysis, principal component analysis, and geostatistical analysis were employed to investigate the factors influencing the distribution of the elements determined in the study area. The results indicate that the distribution of the majority of elements determined, especially for Cr, Ni, and associated elements, is greatly influenced by the geology and geomorphology of the study area. Principal component analysis has yielded four factors that explain over 77% of the total variance in the data. These factors are as follows: lithophilic elements that are associated with Al silicates minerals of K (factor I: 29.4%), ultramafic rocks (factor II: 20.5%), elements that are coprecipitated with Fe and Mn oxides (factor III: 18.0%), and anthropogenic activities (factor IV: 9.3%). The anthropogenic activities that influence the distribution of several potentially toxic elements (i.e., Cd, Cu, Pb, Zn) are agricultural practices and the deposition of fly ash in the vicinity of the local power stations.
