Bioavailability and toxicity of heavy metals in the presence of natural organic matter
(2006)The effect of humic acids (HA) on the toxicity of copper, zinc and lead was investigated in this study, using the photobacterium Vibrio fischeri (Microtox test) as a test organism. The metal species and the complexation ... -
Heavy metal concentrations in Mullus barbatus and Pagellus erythrinus in relation to body size, gender, and seasonality
(2014)Marine environments have been subjected to an increase in heavy metal pollution. Investigations were conducted in the bioaccumulation of heavy metals for both a benthic (Mullus barbatus) and a benthopelagic fish species ... -
Heavy metal concentrations in soils and irrigation waters in Thessaly region, Central Greece
(2005)The purpose of this work was to provide information on heavy metals concentrations in soils and in irrigation water in Thessaly, Central Greece, where tobacco (Nicotiana tabacum) is cultivated. Tobacco tends to accumulate ... -
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 ... -
Influence of some soil parameters on heavy metals accumulation by vegetables grown in agricultural soils of different soil orders
(2008)The main purpose of this research was to determine the levels of heavy metals in tomato, potato and lettuce, grown in agricultural soils of different soil orders (Alfisols, Endisols and Vertisols), located at Central Greece. ... -
Major and trace element contents in apples from a cultivated area of central Greece
(2013)Forty-two soil and apple samples from central Greece were collected and analyzed with regards to the content in major (Ca, Fe, K, Mg, Na, P, and S) and trace elements (As, B, Ba, Cd, Co, Cr, Cu, Hg, Mn, Mo, Ni, Pb, Sb, Sc, ... -
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 ... -
Toxicity effects of bisphenol A to the nauplii of the brine shrimp Artemia franciscana
(2013)Toxicity responses of Artemia franciscano to the endocrine disrupter bisphenol A (BPA) were investigated. Exposure of Artemia nauplii (instar II-III) to BPA for 24 hrs and 48 hrs demonstrated LC50 values of 44.8 mg l(-1) ...
