چشمههای حوزه آبخیز پیرانشهر یکی از منابع مهم تامین منابع آب شرب و آبیاری اراضی کشاورزی است. به همین منظور، در این تحقیق تاثیر وضعیت سنگشناسی و فعالیتهای کشاورزی به عنوان مهمترین عوامل موثر بر کیفیت آب این چشمهها مورد ارزیابی قرار گرفته است. پس از ثبت موقعیت جغرافیایی 145 چشمه، نمونهبرداری آنها در تیر ماه 1391 انجام شد. مقدار پارامتر هدایت الکتریکی (EC) در محل نمونهبرداری و مقدار سا...
The present study was carried out near an industrial area with a high-density urban population and large-scale agricultural activities. These anthropogenic activities lead to groundwater pollution depletion of the water table. This attempted classify sources hydrochemical facies that help ensure suitability for agriculture drinking. Irrigation indexes, quality index (WQI), principal component a...
the factors that have been influential in the damaging and destroying the iranian historical monuments can be divided into two categories: first, the natural phenomena such as floods, earthquakes, famines, and droughts; and second, human behavior that on some occasions had intentionally or unintentionally caused some damages to the historical monuments. the flawed policies of the rulers that ha...
The hydrogeochemical properties of bottled waters (n = 37) were examined to evaluate the factors governing their quality and suggest natural background levels (NBLs) groundwater. sourced from bedrock aquifers various geological types analyzed for 14 physicochemical parameters 48 trace elements. mainly consisted Ca-HCO3 type with low TDS (mean 158.4 mg/L; n 33) regardless type, indicating degree...
Abstract Fluorosis is the most widespread and serious endemic disease in abandoned Yellow River flooding delta of East China. One important causes fluorosis drinking high-fluorine groundwater. In this study, 313 groundwater samples were collected central part to address chemistry high-fluoride groundwater, 33 core from one borehole 150 m depth analyse vertical distribution characteristics total...

The effects of changes in peritubular pH, carbon dioxide tension (PCO2), and HCO3- concentration on net HCO3- transport was examined in in vitro perfused cortical collecting tubules (CCTs) from unpretreated New Zealand white rabbits. Lowering peritubular HCO3- concentration and pH by reciprocal replacement of HCO3- with Cl-, significantly stimulated net HCO3- absorption. Lowering peritubular HC...
