Introduction: Water is vital for life. Its inadequate quality causes significant effects on the health condition of the individuals and society. Groundwater is one of the sources of Nitrate that level over standard limits may lead to several health problems such as hemoglobin metabolism and the formation of nitro amino compounds. Therefore, the aim of this study is determining ...

BACKGROUND The World Health Organization (WHO) released the fourth edition of Guidelines for Drinking-Water Quality in July 2011. In this edition, the 400-µg/L drinking-water guideline for manganese (Mn) was discontinued with the assertion that because "this health-based value is well above concentrations of manganese normally found in drinking water, it is not considered necessary to derive a ...
Introduction: Natural water normally consists of mineral compounds, suspended solids and dissolved gases. Some of these components are necessary for human health, but if more than allowable limits, they will endanger the human health. In this research, important clinical parameters in drinking water of Bandar Abbas were evaluated to compare with the national standards. Methods: In this descrip...
The consumption of jar water has been increasing consistently in these days. To improve such water quality and supply, information is needed to assess water contamination in a variety of community, including those that rely primarily on unimproved distributed sources of drinking water. This study was done to assess the public perception on drinking jar water and assessment of drinking jar water...
Introduction: Monitoring and controlling water resources and using health risk assessment approaches for water pollutants are essential for health promotion programs. This study aims to determine the water quality status and its spatiotemporal variation across the Kan River Basin, explore the interrelationship between surface and groundwater quality indices, and assess the nitrate health risk i...
The applicability of 454 pyrosequencing to characterize bacterial biofilm communities from two water meters of a drinking water distribution system was assessed. Differences in bacterial diversity and composition were observed. A better understanding of the bacterial ecology of drinking water biofilms will allow for effective management of water quality in distribution systems.
