Availability of Cu and Zn in an acidic sludge-amended soil as affected by zeolite application and liming
(2012)Purpose Acidic soils exhibit high trace element availability compared to neutral pH soils, and thus, when trace metals are added (e. g. due to sewage sludge application), measures should be taken to reduce their mobility. ... -
Evaluation of toxic and interactive toxic effects of three agrochemicals and copper using a battery of microbiotests
(2009)Three commonly used test organisms of different trophic levels (Vibrio fischeri, Pseudokirchneriella subcapitata and Daphnia magna) were exposed to selected agrochemicals (fosthiazate, metalaxyl-M, imidacloprid) and copper, ... -
Fish farming and anti-fouling paints: a potential source of Cu and Zn in farmed fish
(2014)The accumulation of copper and zinc, the basic components of anti-fouling paints, was examined in cultured sea bass Dicentrarchus labrax and sea bream Sparus aurata. Samplings were carried out at 4 eastern Mediterranean ... -
Groundwater hydrogeochemistry of Trikala municipality, central Greece
(2013)Sixty-four samples from the groundwater resources of Trikala municipality, central Greece, were collected during two periods (2006 and 2007) and analyzed for physico-chemical parameters (temperature, pH, specific electrical ... -
GROWTH OF WEED AND CROP PLANTS UNDER CADMIUM STRESS AND THEIR PHYTOREMEDIATION POTENTIAL
(2009)Phytoremediation is a promising new technology to remediate ecosystems using certain plants that can accumulate and withstand relatively high concentrations of a pollutant. Growth traits and cadmium (Cd) uptake of two weeds ... -
Hexavalent Chromium Dynamics and Uptake in Manure-Added Soil
(2012)The soil dynamics of hexavalent Cr, a particularly mobile and toxic metal, is of a great environmental concern, and its availability to plants depends on various soil properties including soil organic matter. Thus, in a ... -
Impact of New Soil Amendments on the Uptake of Lead by Crops
(2013)In the present article, the reclamation of lead (Pb)-contaminated soils by adding zeolite, bentonite, goethite, and two newly produced adsorbents consisting of zeolite and goethite (systems I and II) was studied. These ... -
Monitoring the Variability of Nitrogen and Cadmium Concentrations in Soils and Irrigation Water in the Almyros Area of Central Greece
(2009)The main purpose of this investigation was the monitoring of nitrogen (N) and cadmium (Cd) levels in soils and irrigation water samples in an intensively cultivated area in central Greece. From 2005 to 2007, soil as well ... -
Novel quality control methods in conjunction with chemometrics (multivariate analysis) for detecting honey authenticity
(2005)The importance of honey has been recently upgraded because of its nutrient and therapeutic effect. The adulteration of honey increased exponentially in terms of both geographic and/or botanical origin. Therefore, the need ... -
Stabilization of Sewage Sludge by Using Various By-products: Effects on Soil Properties, Biomass Production, and Bioavailability of Copper and Zinc
(2014)Stabilization of sewage sludge (SS) prior to its land disposal may help control the mobility of SS-borne contaminants, particularly potentially toxic metals. We examined the effects of stabilized SS application on soil ... -
Use of clinoptilolite and an Fe-overexchanged clinoptilolite in Zn2+ and Mn2+ removal from drinking water
(2008)Clinoptilolite, a natural zeolite, was used for the synthesis of a high surface area clinoptilolite-iron oxide system (Clin-Fe system) to be used for the removal of Mn2+ and Zn2+ ions from drinking water samples. The new ... -
Use of Modified Zeolites for the Remediation of Waters and Cultivated Soils from Cu(II)
(2012)The ability of iron oxides (goethite) and natural zeolite (clinoptilolite) to adsorb copper from its aqueous solutions was extensively studied in the past. In this paper, the production of modified zeolites (systems I and ...
