Origin and concentration profile of chromium in a Greek aquifer

Geochemistry of serpentine agricultural soil and associated groundwater chemistry and vegetation in the area of Atalanti, Greece

“…These differences are attributed to the limited exposure of unweathered ultramafic rock in Euboea. Comparison of the results of the present study with those reported for the serpentine soils of Vergina (northern Greece) (Dermatas et al, 2014), an area rich in ultramafic rocks, indicates relative lower concentrations. However, the observed differences are affected by the different analytical method used as the total concentrations have been measured in Vergina by XRF.…”

Occurence of Hexavalent Chromium in the Ophiolite Related Aquifers of Loytraki and Schinos Areas

“…Dermatas et al (2015) and Kazakis et al (2015) have also found similar concentrations of Cr(VI) in the areas of Vergina (up to 64μg/L) and Anthemountas (up to 70μg/L) which also have an ophiolite-influenced geological background and aquifers which are related to ultramafic rocks. Furthermore, Dermatas et al (2015) have reported much higher Cr(VI) concentrations, reaching 10 mg/L in groundwater from the area of Oinofyta where industrial activity is intense. The absence of industrial activities in the areas of Loutraki and Schinos as well as the concentrations levels of Cr(VI) are indicative of the natural source of this toxic element in water.…”

“…Hexavalent chromium contamination in groundwater has been reported at several areas of Greece. Elevated concentrations have been attributed to natural processes within ophiolite related aquifers Kaprara et al, 2015;Dermatas et al, 2015), anthropogenic activities in industrial zones such as the notorious case of the Oinofyta-Asopos groundwater contamination or a combination of both, such as the ultramafic rock rich area of central Euboea which is also characterized by intensive agriculture (Voutsis et al, 2015;Megremi et al, 2013). Previously published data from the area of Schinos, which is one of study areas of the present study, reported high concentrations of Cr(VI) in a few domestic water wells within the village and attributed contamination to uncontrolled waste disposal (Papadopoulos and Lappas, 2014).…”

Evaluation of ground water quality near Chandi Devi bridge solid waste dumping site at Hairdwar city, (Uttarakhand), India : A case study

“…compounds in groundwater as a result of inappropriate waste management and disposal practices (Dermatas and Panagiotakis, 2012). Geogenic groundwater pollution for arsenic contamination problem in India and Bangladesh, or the hexavalent chromium contamination in California, Italy, Greece, and elsewhere, is exclusively related to the geochemical background of rock and soil, which feeds groundwater with heavy metals and these are capable of posing significant adverse effects to humans and environment (Dermatas et al, 2015). In biotic perspective, heavy metals enter into living organisms through food, water or frequent contact to emission sources, though few of them serve as vital micro nutrients for living beings but at higher concentration it can lead to severe poisoning (Lenntech 2004).…”
