Background and Aims: Heavy metals pollution is a worldwide problem due to the chemical stability and accumulation properties in living things. High levels of these metals increased mortality, morphological abnormalities, growth retardation and genetic effects in humans. This study investigated the concentration of heavy metals in SIRJAN plain groundwater resources and compared the results with ...
Effects of wastewater discharge on the coastal area in Gaza strip Palestine are not fully investigated. This study investigated effect physical and chemical properties marine water over a period 2 year. Sea sediment samples were collected from about 20 different sites. The sediments wastewater/sea mixing zone at depth 0, 2.5 5 m column direct discharging pipe line location similarly other locat...
Background: In this survey the absorbed dose by kidneys, bladder, liver and ovaries with 99mTc-EC (99mTc Ethylene dicysteine) renal scintigraphy was measured and compared with the absorbed dose from 99mTc-DTPA (99mTc - Dietheylne Triamine Penta-Acid), which often is used in renal scintigraphy.Methods: In this applicable study, we used a water phantom with geometrical sizes similar to that o...
Surface-applied chemicals move through the unsaturated zone with complex flow and transport processes due to soil heterogeneity and reach the saturated zone, resulting in groundwater contamination. Such complex processes need to be studied by advanced measurement and modeling techniques to protect soil and water resources from contamination. In this study, the interactive effects of factors lik...
The defluoridation efficiency (epsilon(F)) of electrocoagulation (EC) is closely related to the pH level of the F(-)-containing solution. The pH level usually needs to be adjusted by adding acid in order to obtain the highest epsilon(F) for the F(-)-containing groundwater. The use of combined EC (CEC), which is the combination of chemical coagulation with EC, was proposed to remove fluoride fro...
EXTENDED ABSTRACT The presence of emerging contaminants has been previously described in reclaimed water and groundwater of Gran Canaria (Spain). Despite of the environmental risk associated to irrigation with reclaimed water (R), this practice is necessary considering sustainability of the hydrological cycle in semiarid zones, especially regarding agricultural activity. The aim of this study w...
Background & Objective: Endometrial carcinoma (EC) has been traditionally classified into two distinct categories of low-grade and high-grade. Type I (low grade) EC, which constitutes the majority of cases, is linked to estrogen-related molecular pathways. But type II (high-grade) EC accounts for 10-20% of cases and behaves in an aggressive way. Pathologic and biological featur...
background: desalination plants have an important role in providing community drinking water. the increasing trend of water consumption and decrease of natural resources of fresh water make this role even more important. the aim of this study was to evaluate the quality of inlet and outlet water of desalination plants by reverse osmosis (ro) process in qeshm, iran and also to compare the qualit...
in order to agroecological zoning of current agricultural lands in golestan province for canola cultivation, geographic information system (gis) and analytical hierarchy process (ahp) were used to match the environmental requirements of crop and the land characteristics. the first, agroecological requirements of canola was identify from scientific resources then classified and needed thematic m...
