This research aims to assess the hydrogeochemical evolution of groundwater in Oued souf valley for drinking and irrigation purposes. To achieve this, 49 samples from complex terminal were examined treated concurrently with multivariate statistical methods, geostatistical modeling WQI (water quality index). Focusing on physico-chemical parameters, Q mode clustering analysis detected four major w...

The dam is a crucial water source for both consumption and irrigation in the Asir region of Kingdom Saudi Arabia. current study evaluates surface quality at examines effects some physicochemical trace metals on using multiple statistical approaches. parameters were measured 27 sites region. Three generated K-mean clustering technique; first group included five sites, second contained 20 third a...

Two new complex copper(II) sulfates [Cu(1,10-phen)(H2O)2]SO4 (1, 1,10-phen = 1,10-phenanthroline) and [Cu(2,2′-bipy)(H2O)2]SO4 (2, 2,2′-bipy = 2,2′-bipyridine) have been hydrothermally synthesized and characterized by IR spectroscopy, elemental analysis, thermogravimetric analysis, and X-ray crystallography. 1 and 2 consist of complex cations [Cu(1,10-phen/2,2′-bipy)(H2O)2]2+ and SO42− anions, ...

Understanding precipitation chemistry is highlighted as important worldwide due to its close relationship with air quality and impacts on ecosystems. However, the chemical composition of limited in Tibet, where alpine ecosystems are sensitive global change. Here, rainwater samples were collected Nyingchi city from January 2021 December 2021, a total 44 obtained. Major ions (NO3−, NH4+, Cl−, SO4...

This article contributes to the development of a thermodynamic model for simulating CO2 solubility in pure water and aqueous brines under different conditions temperature, pressure ionic strength. The modeling activity-fugacity (?-?) approach allows calculating solubility, based on Pitzer electrolyte theory activity coefficient Peng-Robinson's equation state fugacity. present work proposes new ...

The aim of this research was to study the relationships between presence of plant species and environmental factors in Garizat rangelands of Yazd province and providing their predictive habitat models. After delimitation of the study area, sampling was performed using randomized-systematic method. Accordingly, vegetation data including presence and cover percentage were determined in each quadr...

Ghale-madreseh is the first point that the saline and sulfurous streams flow into Tembi River, one of the well-known saline rivers in Khuzestan province, Iran. This river is one of the main sources of increasing Karun River’s salinity, which is the largest river in Iran in terms of discharge. There are three saline and sulfurous springs (Shour-1, Shour-2m and Namak Springs) as well as a drinkab...

Chara buckellii G.O.A., a salt-tolerant alga, has a less negative membrane potential (Em) when cultured in saline medium (artificial Waldsea water) than when cultured in freshwater. The cell hyperpolarizes and membrane conductance (Gm) decreases when the external medium is changed from Waldsea control solution (WCS), a high-salt medium, to low-salt medium containing sufficient sorbitol to gener...
