“…However, earlier research in the broad area of Keratsini harbor has produced lower Zn, Pb, Cr, Cu, and Mn values (Grimmanis et al 1977;Scoullos 1981;VoutsinouTaliadouri 1981;Scoullos 1986;Sioulas et al 1990;Zorpas et al 2001). According to Table 2 the concentration levels of Cd, Pb, Zn, and Cu observed in the surface sediments of Keratsini harbor are also higher than the concentrations traced in similar harbors in Greece, e.g., in the harbor of Rhodes Fig.…”

The contents of ten elements [Cd, Pb, W, Zn, Mn, As, Se, Cr, Cu, and organic carbon (C org )] have been determined in the surficial sediments of Keratsini harbor, Saronikos Gulf, Greece. The contamination of the sediments was assessed on the basis of geoaccumulation index and to corresponding sediment quality guidelines (SQGs) effects range low/effects range median. The results revealed highly elevated Cd, Pb, W, Zn, As, Se, Cr, Cu, and C org values (Cd, 190-1,763 mg kg −1 ; Pb, 521-1,263 mg kg −1 ; W, 38-100 mg kg −1 ; Zn, 409-6,725 mg kg −1 ; Mn, 95-1,101 mg kg −1 ; As, not detectable-1,813 mg kg −1 ; Se, not detectable-58 mg kg −1 ; Cr, 264-860 mg kg −1 ; Cu, 195-518 mg kg −1 ; and C org , 0.69-4.41%). The enrichment of metals in the sediments results from the contribution of the central Athens sewage outfall through which the waste of the Attica basin ends up in Keratsini harbor as well as from industrial and ship contaminants.

“…According to Filella et al (2002), Sb background concentrations in sediments and soils are on the order of 0.2-10 mg/kg. Higher concentrations are directly related to anthropogenic sources, mainly smelting plants (Crecelius et al, 1974;Papakostidis et al, 1975;Grimanis et al, 1977;Ragaini et al, 1977;Ainsworth et al, 1990;Asami et al, 1992;Li and Thornton, 1993).…”

Natural attenuation of antimony in mine drainage water

et al. 2007

In this study, we investigated the natural attenuation of antimony (Sb) in the drainage water of an abandoned mine. Drainage water, waste rocks, and ocherous precipitates collected from the mine were investigated in terms of their mineralogy and chemistry. The chemistry of the drainage water was analyzed by measuring pH, oxidation-reduction potential (ORP), and electric conductivity on site as well as by inductively coupled plasma mass spectrometry and ion chromatography. As the drainage flowed downstream, the pH decreased rapidly from 7.05 to 3.26 and then increased slowly to 3.50. In a section where the pH increased, ocherous precipitates occur on a drainage water channel. We determined Sb levels in the drainage water, and the distribution of Sb in the mineral phases of waste rocks and precipitates was estimated by means of a sequential extraction procedure. The results of these investigations indicated that Sb, which is generated by the dissolution of stibnite (Sb 2 S 3 ) and secondary formed Sb minerals in waste rocks, was attenuated by iron-bearing ocherous precipitates, especially schwertmannite, that form over time in the drainage water. The Sb concentrations in the ocherous precipitates were up to 370 mg/kg, whereas the Sb concentrations in the drainage water downstream were below background levels (0.6 µg/L). Bulk distribution coefficients (K d ) for this Sb adsorption to the precipitates ranges up to at least 10 5 L/kg.

“…Organic matter contents in the near-bottom water column tend to be lower (see Fig. 4), whereas mineral and lithogenic contents tend to be increased (Grimanis et al, 1977;Galanopoulou, 2009). Increased minerals result in higher settling velocities (e.g., Ziervogel and Forster, 2005) which translate into shorter residence times of the particulate material in a given interval of water.…”
