In this study, the effects of enhancing synthetic chelators (HEDTA, EGTA) and low molecular weight organic acids (LMWOA) such as citric acid were compared on cadmium (Cd) solution in soils that were artificially contaminated. Also Cd phytoextraction capability by radish (Raphanus Sativus L.) was studied. The experiment was laid out in a randomized complete factorial design where each treatment ...
A Spectrophotometric investigation was applied on the complexation of 1,3-bis (3-(2-pyridyl) pyrazol-1-ylmethyl) benzene (1,3-PPB) and 1,4-bis (1,4-PPB) with Zn(II) Cd(II) ions in a mixed (1:1) solvent water ethanol. The mole ratio methodology used to calculate stoichiometry, molar absorptivity, stability constant values. Some experimental conditions have been investigated, including pH, ionic ...
The aim of this study was to adapt MARMS with some modifications to detect beta mutation in our cohort of thalassemia patients. We focused only on transfusion-dependent thalassemia Malay patients, the predominant ethnic group (95%) in the Kelantanese population. Eight mutations were identified in 46 out of 48 (95.83%) beta thalassemia alleles. Most of the patients (54.2%) were compound heterozy...
background and objectives: the mobility, bioavailability and environmental fate of heavy metal ions in soil are controlled by sorption onto soil minerals and solid organic matter. the sorption is strongly affected by the presence of various low-molecular-weight organic acids. the main objective of this study was to investigate the effects of oxalic acid on sorption of cd on clay fraction of a s...
Cadmium (Cd) and lead (Pb) are recognized as the most toxic metal ions due to their detrimental effects not only to plants, but also to humans. The objective of this study was to investigate the effects of Cd and Pb treatments on seed germination, plant growth, and physiological response in tall fescue (Festuca arundinacea Schreb.). We employed six treatments: CK (nutrient solution as control),...
To investigate the potential of corn (Zea Mays) for cleaning of soils polluted by cadmium and the effect of different levels of sulfur (S) element on biomass and root and concentration of some micronutrients, a greenhouse experiment was performed in Zanjan University in 2008. In the completely randomized factorial design with three replications, three levels of elemental S (0, 1 and 2 ton ha-1...
BACKGROUND Variation in susceptibility to cadmium (Cd) toxicity may partly be due to differences in Cd toxicokinetics. Experimental studies indicate that zinc (Zn) homeostasis proteins transport Cd. OBJECTIVE To evaluate the potential effect of variation in Zn-transporter genes (SLC39A8 and SLC39A14) on Cd concentrations in blood and urine. METHODS We studied women from the Argentinean Ande...
afforestation of contaminated areas is considered as a possible strategy for reduction of contaminations. in the present study, the effects of lead (pb) and cadmium (cd) were investigated on chlorophyll fluorescence parameters (fv/fm, fo, and fm), photosynthetic pigments (chlorophyll a, b, and total chlorophyll), and proline in one-year-old seedlings of celtis caucasica and robinia pseudoacacia...
به رغم اثرات بسیار نامطلوبی که آلودگی خاک بر کیفیت تولیدات مواد غذایی و درنهایت بر زنجیره غذایی انسان و همینطور دیگر اجزا محیط زیست دارد، قدرت خاک برای زیست پالایی این آلاینده ها از جمله کادمیم (cd) در گذشته کمتر مورد توجه قرار گرفته است. کادمیم از جمله آلاینده هایی است که به شدت سمی و برای گیاه و انسان خطر آفرین می باشد. پالایش سبز یکی از ابزارهای مفید برای کاهش غلظت آلاینده ها از جمله cd در خ...
