A factorial experiment with two levels of Zn (0 and 1.5 mg Zn kg-1), five salinity levels of irrigation water (0, 60, 120 and 180 mM NaC1, and 120 mM NaNO3) in three replications was conducted. Wheat (Triticum aestivum cv. Roshan) was seeded in pots. After plant harvesting, zinc and cadmium concentrations were determined in the shoot. Activities of metal species in the soil solution were predic...
Introduction: Vegetables are important things of alimentary diet and beeing exposed to polluted alimentary diet of heavy metals via consumption of vegetables, be carried to account a risk for human health. This thesis have been done with target of appointment of concentration of cadmium, nickel, lead and zinc metals in soil and parsley and health risk assessment of this metals in withdrawed par...
abstract the use of plants for remediation of heavy metals contaminated soils is an economical, cheap and effective strategy. this research was conducted in order to study the effect of potassium chloride on cadmium uptake and enhancement of it's phytoremediation by canola (brassica napus l.) and sunflower (helianthus annuus l.) in a cadmium polluted soil from angoran in zanjan province. in a r...
Cadmium (Cd) pollution is a major environmental and human health threat. Therefore there is a need for cost-effective remediation procedures. Chelators such as humic acid have shown positive effects in enhancing resistance to various stresses. The objective of this research was to investigate the use of humic acids at cadmium-contaminated soil on growth and soluble sugar concentration of aloe v...
abstract venlafaxine, 1–[2–(dimethylamino)–1–(4–methoxyphenyl) ethyl]cyclohexanol hydrochloride is a novel non-tricyclic antidepressant. venlafaxine is a second generation antidepressant drug, has a neuropharmacologic profile distinct from that of existing antidepressants including tricyclic compounds, selective serotonin reuptake inhibitors and monoamine oxidase inhibitors. venlafaxine impart...
Establishment of phosphate (P) retention and release capacity of soils is essential for effective nutrient management and environmental protection. In this experiment, we studied the influence of soil properties on P desorption and the relationship between phosphate sorption and desorption. Among the soil series, the Ghior soil had the highest percent clay (59.32%) and free iron oxide (15,241 m...
studies on adsorption, desorption and reaction kinetics of carbendazim in grey-brown podzolic soil derived from loamy sand (Albic luvisls), grey-brown podzolic soil derived from silt (Haplic luvisols) and brown soil derived from sandy clay loam (Haplic Cambisols) were carried out. Five concentrations of carbendazim (5.0, 3.8, 2.6, 1.0 and 0.2 μg ⋅ cm-3) in 0.01 mol ⋅ dm-3 CaCl2 were used for th...
the present pot experiment was undertaken to investigate the phytoremediation potential of corn and oat in soil. treatments consisted of four cadmium (cd) levels (0, 5, 10 and 20 mg l 1) and three irrigation intervals (1, 3 and 7 days), arranged in the form of a complete randomized design with three replications. corn and oat were harvested after 75 and 90 days, respectively. transpiration rate...
in this study reference as one of the five cohesive devices in the achievement of textuality in english and persian narrative/descripitive written texts is focused on and analysed . to do so , the theoretical framework elaborated by halliday and hasan (1976) and its version adapted by the writer to match the sub-types of reference in farsi are applied to the analysis of reference in english and...
