The present investigation has been conducted to assess the status of physico-chemical parameters as well as the concentrations of some selected heavy metals to understand the present scenario of water quality at Perak River basin, Malaysia. The temperature, turbidity, pH, EC and DO values of all the examined samples have been within the range of 25.0 to 30.5 0C, 39.5 to 168.00 NTU, 6.8 to 7.33,...
evaluating the quality and quantity of water resources is crucial for a sustainable development. one of the simplest methods that is able to indicate the conditions of water quality in a short period and at a low cost, compared with the physicochemical methods, is by using the biological water quality indices. identifying the contamination of water resources using biomarkers, especially indices...
this study focused on use of bacterial extracellular enzyme activities as biochemical parameters, along with the microbiological and physicochemical characteristics, in a comprehensive assessment of water quality of four lake ecosystems in the province of vojvodina (northern serbia): provala, ludas, zobnatica and palic. water samples were collected in june and october, 2008. for assessment of ...
Comprehensive assessment of water quality is an important technological measure for water environmental management and protection. Previous assessment methods tend to ignore the influences of sediment pollutant release and dynamic change of the water boundary. In view of this, this paper explores a new method for comprehensive water quality assessment. Laboratory simulation experiments are cond...
Introduction & Objective: Rivers are one of the main water supply resources for various uses such as agricultural, industrial and drinking purposes. As population and consumption increase, monitoring of rivers water quality becomes an important function of environmental management field. Because Darreh-Morad Beyg river of Hamadan is a water supply for different purposes and many pollutants ar...
The purpose of research: to determine the costs, chemical composition, mineralization and state water pollution small Sarata River according ecological sanitary criteria, specific substances toxic action, assess suitability for irrigation indicators. Data Methods. Research methods are based on systemic analysis general principles objectivity, causality, relevance evolution. Of traditional scien...
Indices qualitative pollution is one of procedures involved in managing quality water can be a powerful management tool for decision-making, as an appropriate-use. In this paper, using done index quality water BCWQI and index pollution water Liou evaluate quality of river Bahmanshir. Sampling was within one year (2019) and 5 stations conducted. Quality parameters were investigated including: te...
Kosovo has limited natural water resources which should be well managed. This is recently realised through quantitative and qualitative monitoring of both surface and groundwater and by characterizing their quality according to their destination. In this paper, the Water Quality Index (WQI) developed by the Canadian Council of Environment Ministers (CCME WQI) was applied to evaluate the groundw...
The development of a surface water evaluation index is a critical factor in the assessment, restoration and protection of stream water quality. Quantifying water pollution in specific grade using dominant parameters is important, as this can explain the current state of water pollution with accuracy. As a result, an integrated multi-parameter water quality index has been developed. It is based ...
Background and Objective: With the industrialization of communities, population increase and use of surface water, river pollution has been increased by agricultural, industrial pollutants and urban wastewater. Therefore, investigation of river pollution for regional and environmental planning is of great importance. To evaluate surface water pollution, a number of surface water quality indices...
