Solubility and bioavailability of heavy metals are important with respect to theirtoxicity. The discharge of municipal wastewater in soil and surface waters can affectbioavailability and mobility of heavy metals in soils and sediments. The effect of dischargeof Arak municipal wastewater on the KNO3 and DTPA extractable heavy metals in a salinesoil sampled from Mighan playa (Iran) compared to a ...

Perchlorate (ClO4 ) has been detected in numerous ground and surface waters, and has recently been added to the drinking water Candidate Contaminant List in the United States. Perchlorate can be removed from drinking water using ion exchange, but this results in the production of highly saline (7–12%) perchlorate-contaminated brines. Perchlorate-degrading microbial enrichments capable of growth...

groundwater quality has a direct impact on human life. the main objective of this research is to investigate changes in groundwater quality and levels in lake urmia basin. tasoj and shiramin plains are selected as a study area. the suitability of groundwater quality for drinking and agricultural purposes were assessed using schoeller and wilcox diagram. according to the wilcox classification, t...

Saline irrigation water accounts for 15% to 30% of global, anthropogenic, usage, and around 10% global arable food production. Decreasing the salinity this has potential substantially increase yields associated with these crops. In paper, 87 sol–gel hydrophobic supra-hydrophobic, hollow, metal, hydroxyoxide polymer formulations (constructed using inexpensive, agricultural chemicals) were demons...

In a field experiment the effects of irrigation with saline drainage water (seasonal average of 4.5 dS/m) and non-saline water (0.55 dS/m) applied by two different water management strategies (cyclic or blended saline water with non-saline water in different ratios) and two different irrigation methods (drip or furrow) were studied on growth and productivity of tomato (Lycopersicon esculentum M...

BACKGROUND Rearing rats in environmental enrichment alters psychostimulant-induced locomotor activity as well as neurotransmitter expression. Exposure to novelty and psychostimulants induces c-fos expression in neurons in the mesolimbic dopamine (DA) pathway. Here we investigated changes in the expression of the immediate early gene c-fos in the mesolimbic DA pathway of enriched, isolated, or s...

Coastal salt-affected soils account for a large area all around the world. Soil salinity and pH are two important parameters affecting soil quality. Investigating correlation of electrical conductivity (EC) at different depths in saline was useful quickly assessing saline–alkaline characteristics. During natural desalination process field reclaimed lands, phenomena increase nitrogen accumulatio...
