Screening of polar pesticides in groundwater in Hebei Province, China
Huang Y., (Corresponding) Rao Z., GUO X., YANG Z., LIU C., SHI Z.
Topic:
Soil and groundwater contamination and remediation
As a big agricultural country，China has a relatively high pesticide usage in unit area , which is three times higher than developed countries. About 80% of pesticides directly enter the soil and the water through leaching or surface runoff during the usage of pesticides. In particular, some of the...Read more

Soil and groundwater contamination and remediation
Agricultural activity of spreading fertilizers may, in case they are washed away to an aquifer, result in a groundwater contamination. There was a research conducted in Croatia on the lower part of the Danube-Sava canal which is occupied by extensive agricultural production to measure the...Read more

CrVI contaminated groundwater in the Mediterranean: Case study from Mersin, Turkey
(Corresponding) HATIPOGLU-BAGCI Z., BAYARI C., CANAKCI A.
Topic:
Efficient water resources management in cr(vi) impacted water bodies
Increasing population, industrialization, agricultural and tourism activities in Mediterranean countries not only increase the water demand but also led to deterioration of water quality. Water quality degredation is a common problem in all circum-Mediterranean countries and there is an increasing...Read more
Per-and polyfluoroalkyl substances (PFAS): an emerging contaminant
(Corresponding) Toskos T., Panagiotakis I., Dermatas D.
Topic:
Soil and groundwater contamination and remediation
PFAS compounds are ubiquitous in the environment and in consumer products. Unlike other emergent contaminants this is a family of compounds with, literally, thousands of compounds. Our knowledge of toxicological and environmental fate and transport properties is an evolving field. On the other hand...Read more
Seasonal variation and spatial distribution of arsenic in groundwater in a rhyolithic volcanic area of Lesvos Island, Greece
(Corresponding) ZKERI E., ALOUPI M., GAGANIS P.
Topic:
Heavy metals in the environment
A research conducted in water wells located in the rhyolithic volcanic area of Mandamados, Lesvos Island, Greece, indicated that significant seasonal variation of arsenic concentration in groundwater exists mainly in wells near the coastal zone. However, there were differences among those coastal...Read more
Groundwater quality and hydrogeochemical characterization of Khetri copper mining region, India
(Corresponding) Punia A., Siddaiah N., (Corresponding) Bharti R.
Topic:
Soil and groundwater contamination and remediation
The impact of copper mine on groundwater quality in the semi-arid region is evaluated, and also characterized for hydrogeochemical processes. Groundwater samples (post monsoon and pre monsoon) from Khetri copper mine region of Rajasthan, India were studied. In majority of groundwater samples, the...Read more
Geochemical modeling as a tool to investigate chromium contamination in groundwater
(Corresponding) Apollaro C., Fuoco I.
Topic:
Soil and groundwater contamination and remediation
The geochemical modeling is an essential tool to understand the water-rock interaction processes. In this work has been used the reaction path modelling to investigate the release and fate of geogenic Cr in ophiolitic Italian areas. During the water-rock interaction the geogenic trivalent Cr...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
A DPSIR approach to selected Cr(VI) impacted groundwater bodies within Attica and Eastern Sterea Ellada River Basin Districts
(Corresponding) Pyrgaki K., Argyraki A., Kelepertzis E., Botsou F., Megremi I., Karavoltsos S., Mpouras A., Dassenakis M., Hatzaki M., Dermatas D.
Topic:
Efficient water resources management in cr(vi) impacted water bodies
The holistic approach of the Driver-Pressure-State-Impact-Response (DPSIR) analytical framework in combination with Geographical Information Systems was applied to selected Cr(VI) impacted groundwater bodies. For the characterization of “state”, 157 samples including field blanks were collected...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
