Heavy metal pollution dispersion simulation in rivers and predicting spatial and temporal variations of pollutants can be used to determine the precise place and to schedule water withdrawal time for drinking, agriculture, aquaculture and ecosystem studies. To study the movement of heavy metal pollution through Karoon flow model, MIKE 11 was employed fpr simulation of the flow model of Karoon R...
The adsorption and removal of congo red from an aqueous solution by iron oxide nanoparticles (IONPs) coated with cetyltrimethylammonium bromide (CTAB) as adsorbent was reported. The novel magnetic separation was quite efficient for the adsorption and desorption of congo red. The effect of temperature, pH of aqueous medium, and interfering ions on the recovery process were also investigated. The...
In order to study the effect of drought stress on growth of new hybrids of maize an experiment was carried out at Safi Abad Agricultural Research Center, Dezful, Iran. The experiment was arranged as a split plot in a randomized complete block design with three replications. Treatments consisted of four levels of drought stress (irrigation after 75(±5) (Control), 95(±5) (mild stress), 115(±5) (m...
geo-statistical distribution of heavy metals in karoon river’s soil by geographic information system
introduction: soil has an important role in nutrient cycle and an important function in storage, refinement, and movement of nutrients for the living and non-living parts. soil pollution of heavy metals and elements is one of the common pollution impacts of human activities, especially industry. realization of distribution pattern of these elements and their anthropogenic sources is a major par...
a study with travel cost method (tcm) was performed to evaluate ecotourism demand of lake belonging to karoon 3 dam. for this purpose, 220 clawson questionnaires at highest demand time (february to may 2008) were completed. results of this investigation showed that forecasting outdoor recreational value of karoon 3 dam limits is equal to 2,879,550,000 rials at month, during study. in order to p...
