در بین اکوسیستمهای آبی، تالاب ها از لحاظ اکولوژیک و زیست محیطی اهمیت بسزایی دارند، زیرا آنها به عنوان مکان تجمع و پذیرنده مواد مغذی و غیر مغذی، حفاظت از تنوع زیستی جانوری و گیاهی، تصفیه طبیعی کیفیت آب، اثرات میکروکلیمایی در منطقه، نقش موثری را ایفا میکنند. بنابراین ارزیابی کیفیت شیمیایی، فیزیکی و برآورد حجم آب آنها برای بررسی و پایش کیفیت، پیشگیری از آلودگی و حفاظت از تنوع زیستی ضروری ...
در این پژوهش به ارزیابی غلظت فلزات سنگین در منابع آب و خاک منطقه سنگ بست که در حدود 40 کیلومتری جنوب شرق مشهد واقع میباشد، پرداخته شده است. جهت این مطالعه، تعداد 17 نمونه رسوب و 10 نمونه آب جمعآوری شده است. pH رسوبات منطقه در محدوده قلیایی قرار گرفته است. این امر را میتوان منتسب به حضور کانیهای سولفیدی (آرسنوپیریت) دانست. در خاکهای منطقه کروم از غنیشدگی خیلی شدیدی برخوردار است. حضور عنصر ...
This study is used the water quality index (WQI), which generated by combining several parameters. gives a helpful representation of overall for public and all intended applications, it demonstrates that pollution beneficial in management decision-making. The Euphrates River was assessed order to determine drinking water. using WQI, includes ten physicochemical criteria. achieved submitting com...
In order to improve the treatment processes of drinking water plant (DWTP) located near Butoniga reservoir in Istria (Croatia), a prediction quality index (WQI) was done. Based on parameters such as temperature, pH, turbidity, KMnO4, NH4, Mn, Al and Fe, calculation WQI conducted, while for models, along with mentioned parameters, O2, TOC UV254 were additionally used. Four models built predict t...
Artificial intelligence methods can remarkably reduce costs for water supply and sanitation systems help ensure compliance with the quality of drinking wastewater treatment. Therefore, modelling predicting to control pollution has been widely researched. The novelty proposed system is presented develop an efficient operation monitoring a sustainable friendly green environment. In this work, ada...
Geographic Information System (GIS) technique was used in this study to produce a Water Quality Index (WQI) map assess the water of Habbaniya Lake for drinking purposes. Sixteen samples fresh surface were collected and analyzed verify physiochemical parameters WQI. These include Total Dissolved Solids, pH, Calcium, Magnesium, Sodium, Potassium, Chloride, Sulfate, Nitrates. The result these has ...
The present study was conducted to evaluate the quality of drinking water and assess potential health hazards due contaminants in selected urban areas Lahore, Pakistan. Water samples were collected from ten sites analyzed for different physico-chemical parameters including turbidity, color, pH, total dissolved solids (TDS), nitrates, fluoride, residual chlorine, hardness. Additionally, heavy me...
Abstract Water resource is most essential basic for human being. Today water management has become an important issue (Kharake, Pathare, Deshmukh, Arebian J Geosci 14(10):1–10, 2021) all developing countries. Rapid growth of population and its repetitive activities along the river pose a concerned impact on system. The quality quantity are under constant pressure by presence different like remo...
Background and Objectives: Dez dam located on Karun River is one of the largest Iranian dams. In a field study, EC, NO3, NH4, PO4, turbidity, TS, alkalinity, coli, temperature, chlorophyll a, DO, BOD5, and Secchi disk (at depths of 0, 2.5, 5, 10, 25, and 50 m)were measured at five sampling points during 2011-2012 water year. Materials and Methods: Water Quality Index and TSI were calculated for...
