This study was carried out in the summer of 2005 and investigated all of active public swimming pools (85 out of 93) in Amman, the capital of Jordan. The aim of this study was to find out if these swimming pools are in compliance with Jordanian Standards for Swimming Pools Water (JS 1562/2004). The pools were surveyed against the water microbial quality and other physicochemical parameters indi...
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 ...
بررسی کیفیت میکروبی و فیزیکوشیمیایی آب شرب روستاهای شهرستان تکاب در استان آذربایجان غربی در سال 1392
Background and Objective: Microbial and physicochemical properties of drinking water، considering type and quantity of drinking water, are factors for determining the acceptability of water. The effects of each of the above components on increasing the quality of water or threatening the health of consumers are also considerable. We aimed to investigate the trace amounts of microbial, physicoch...
There is substantial concern that microbial and nutrient pollution by cattle on public lands degrades water quality, threatening human and ecological health. Given the importance of clean water on multiple-use landscapes, additional research is required to document and examine potential water quality issues across common resource use activities. During the 2011 grazing-recreation season, we con...
The development of the leather industry in the Aojiang watershed of Zhejiang province increased the release of waste water. In the waste water, ammonium nitrogen (NH(+) (4)-N) and germanium (Ge) are the main pollutants. In recent years, literature has documented that the intake of high concentrations of NH(+) (4)-N and Ge harms human health and biological species. This paper focuses on assessin...
some physicochemical parameters of honey have been introduced by the international honey commission to evaluate its quality and origin but processes such as heating and filtering can affect these parameters. in traditional iranian medicine, deslagging process involves boiling honey in an equal volume of water and removing the slag formed during process. the aim of this study was to determine th...
