The aim of this study was to assess the potential impact of Trout farm effluents on water quality of Zaringol stream based on NSFWQI and WQI indexes. Some physicochemical water quality parameters were measured from 14 point during December 2009 to September 2010 seasonality. The average value of NSFWQI is 53.21 and it shows spatial and temporal variation. The maximum value or best water quality...

The concentrations of toxic effluents released into freshwater aquatic environments are increasing day by day and affect the aquatic biota. The present study outlined the evaluation of physicochemical parameters such as water temperature, pH, dissolved oxygen (DO), biological oxygen demand (BOD), chemical oxygen demand (COD), phosphates (PO42--P), nitrates (NO3--N), electrical conductivity (EC)...

The discharge of nutrients, phytoplankton and pathogenic bacteria through ballast water may threaten the Cayo Arcas reef system. To assess this threat, the quality of ballast water and presence of coral reef pathogenic bacteria in 30 oil tankers loaded at the PEMEX Cayo Arcas crude oil terminal were determined. The water transported in the ships originated from coastal, oceanic or riverine regi...

Abstract This study considered three different water quality indices (WQIs) for groundwater data collected from the middle-west part of Bangladesh, and quantitative results were justified with globally accepted guidelines. It compared between Canadian WQI Weighted Average WQI, Mierels drinking irrigation purposes, respectively. The revealed that method categorized as ‘fair’ while model showed ‘...

This is the first comprehensive examination of Turyanchay River in Azerbaijan, focusing on water quality (WQ), contamination, and biodiversity at four different locations: Gabala, Agdash, Udjar Zardab. The study analysed nutrient (nitrate, ammonium, phosphate) metal/metalloid (Pb, Cu, Ni, Zn, Mn, Cr, Cd, Fe Al) contamination levels, as well diversity macrozoobenthos river, birds vegetation. che...

Water quality assessment has become a very essential scientific procedure for qualifying water drinking and general purpose use, better public health policy on clean supply. Various tools have been employed to determine the status of systems drinking, industrial use. For this study, index (WQI) recently developed pollution (WPI) adopted evaluate Molo basin. The world organization (WHO) defined ...
