The rapid growth in the world population resulted an increase of freshwater needs many sectors. Groundwater is most important source specially for arid and semi-arid regions due to lack surface water sources low precipitation rates those regions. In this study, monthly groundwater quality data were collected from eleven well fields Sharjah over period 2004-2017. Water parameters including bicar...
there are several factors influencing the water quality based on its usage. the quality of drinking water is of the vital concern for human health and life. an essential attempt has to be done to develop a water quality index (wqi) corresponding with different conditions and characteristics of the relevant river or water body such as geographical, hydrological, discharge rate and pollution sou...
one of the sacred water tank brahmsarovar, at kurukshetra in india was studied to assess the impact of mass bathing during new moon day (called as amavasya in india) in terms of physico-chemical and biological characteristics. overall water quality index was calculated using online calculator. results have revealed significant (p
background: multiple sclerosis (ms) is a neurological disease with fatigue as most prevalent symptom. psychopathological symptoms, physical and mental dysfunctions and body mass abnormalities potentially could deteriorate fatigue. thus, in this study, we aimed at evaluating the effect of these factors on fatigue severity of ms patients. methods: in this cross-sectional study, 162 patients with ...
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...
Inland wetlands are of the most important natural terrestrial types of water resources. Against its importance in protecting and improving biodiversity, air quality and macro-climatic condition of their regions, industrial development, and urbanization treat their natural existence and behavior. Therefore, monitoring and quality evaluation of wetlands are necessary to analyze and infer their na...
