Occurrence and distribution of hexavalent chromium in ground and surface waters in Cyprus under the CrITERIA project

(Corresponding) Zissimos A., Christofi C., Christoforou I., Rigas M.

Topic:

Efficient water resources management in cr(vi) impacted water bodies

The origin and distribution of hexavalent chromium, Cr (VI) over four seasonal cycles was investigated through a conceptual model that included three aquifer systems in Cyprus. An extensive water sampling grid covered two areas of known sea water intrusion of the local coastal aquifers, namely the...Read more

Preliminary study on Cr-rich groundwater treatment by membrane processes

(Corresponding) Fuoco I., Figoli A., brozzo g., De Rosa R., Bloise A., Criscuoli A., (Corresponding) Apollaro C.

Topic:

Efficient water resources management in cr(vi) impacted water bodies

The aim of this work has been treat Cr- rich groundwaters through membranes processes as alternative to conventional methods. Chromium (Cr) is a dangerous element for environment and human health. Commonly, the highest concentrations Cr are detected in ophiolitic areas where ultramafic and...Read more

Synthesis of kaolin supported nZVI and evaluation for the removal of Cr(VI) and Ni from waste streams

(Corresponding) Toli A., Mystrioti C., Della A., Thymi S., Papassiopi N.

Topic:

Efficient water resources management in cr(vi) impacted water bodies

This study involved the synthesis of kaolin-supported nano zero valent iron (K-nZVI) and the evaluation of its performance for the removal of chromates and nickel from contaminated waters. K-nZVI was prepared by mixing a kaolin sample with a FeCl3 solution, followed by the addition of sodium...Read more

Geogenic Cr(VI) in groundwater of the Pollino Massif (southern Apennines): occurrence and remediation

(Corresponding) Paternoster M., Rizzo G., Sinisi R., Vilardi G., Di Palma L., Mongelli G.

Topic:

Efficient water resources management in cr(vi) impacted water bodies

In this study total Cr, Cr(VI), Ni, major and some trace elements were determined in groundwater of northern sector of the Pollino Massif. The investigated area is characterized by ophiolitic rocks consisting of metabasites and cataclastic and highly fractured serpentinites. Two different hydro-...Read more

Harmonization of sampling and chemical analysis for the study of Cr(VI) water contamination in aquifers of eastern Mediterranean and Oman: the CrITERIA project experience

(Corresponding) Argyraki A., Kelepertzis E., Pyrgaki K., Botsou F., Megremi I., Dermatas D.

Topic:

Efficient water resources management in cr(vi) impacted water bodies

The CrITERIA project aims to deliver a harmonized data base, to assist water resource management organizations and water users on decision making when coping with water scarcity, climate extreme events and contaminated water. Contamination by Cr(VI) is used as an example of a specific water...Read more

Evaluation of calcium polysulfide as a reducing agent for the restoration of a Cr(VI)-contaminated aquifer

(Corresponding) MPOURAS T., PAPASSIOPI N., LAGKOUVARDOS K., MYSTRIOTI C., DERMATAS D.

Topic:

Efficient water resources management in cr(vi) impacted water bodies

This work aims at investigating the efficiency of applying calcium polysulfide (CPS) as a reducing agent for the decontamination of a heavily Cr(VI)-contaminated aquifer. Series of batch experiments were carried out in order to evaluate the reductive behavior of CPS towards the aqueous and solid...Read more

Natural presence of hexavalent chromium in spring waters of South-West Mountain Vermion, Greece

STAMOS A., SAMIOTIS G., PEKRIDIS G., TSIOPTSIAS C., (Corresponding) AMANATIDOU E.

Topic:

Efficient water resources management in cr(vi) impacted water bodies

Hexavalent chromium in water occurs as oxoanions that are toxic for plants and animals. Furthermore, they are soluble and extremely mobile under environmental conditions. Chromium in its other common oxidative state (Cr+3) is less toxic and in general immobile. Chromium is found in nature mainly in...Read more
