Among the 3rd Seminar for PhD students working on Water and Health which was held in Cannes on 27–29 June 2011, experts from a number of universities and research institutes took the opportunity to discuss the emergence of Escherichia coli O104:H4 in Europe. Especially, possible threats for European water suppliers were considered. The consensus is summarized in this report. The main conclusion...

Ground waters in the region of Autonomous Province of Vojvodina, Republic of Serbia are endangered by arsenic (up to 0.750 mg/l). Total arsenic concentration was determined In samples of untreated and treated water from some local and central water-supply systems. Results are compared to actual regulations in the country. This analysis encompassed 324 drinking water samples of various sources, ...

Background and Purpose: Fluoride is a natural element essential for human nutrition due to its  benefits for dental enamel. It is well-documented that standard amounts of fluoride in drinkingwater can decrease the rate of dental caries. This study was conducted with the aim of measuring fluoride concentration of drinking-water supplies and urban distribution system in Qom, I...

BACKGROUND To design the most appropriate interventions to improve water quality and supply, information is needed to assess water contamination in a variety of community settings, including those that rely primarily on unimproved surface sources of drinking water. OBJECTIVES We explored the role of initial source water conditions as well as household factors in determining household water qu...

during the past two centuries, production and consumption of nitrate, especially in agricultural field, have been increased considerably. currently many countries in the world including iran encounter to a high nitrate level in drinking water. the main reason is the seepage of agricultural runoff and municipal and industrial wastewater to water resources, particularly groundwater. from the old ...

background: cement production is associated with heavy metal emissions and environmental pollution by cement dust. the degree of contamination of drinking water sources by major and trace elements present in cement dust generated by united cement factory (unicem) is still uncertain. this study estimated the element content of ground and surface water samples (hand-dug wells, boreholes and strea...

introduction: giardia and cryptosporidium are two of the most common parasitic protozoa that cause acute intestinal infections in children, all of the world. these parsites find in water environments, such as untreated water , wastewaters and even treated water. according to, a precise study on surface water was not done, in our country, necessity of precise study by ifa method that is prescise...

this experiment was carried out to study the effect of sodium chloride from drinking water and feed intake on the quality of egs from laying hens. four hundred and twenty native and white leghorn laying hens ranging from 36 to 43 weeks of age were used. seven experimental treatments containing different levels of salt supplied by feed and/or drinking water were compared. increasing salt int...

UNLABELLED The majority of biomass within water distribution systems is in the form of attached biofilm. This is known to be central to drinking water quality degradation following treatment, yet little understanding of the dynamics of these highly heterogeneous communities exists. This paper presents original information on such dynamics, with findings demonstrating patterns of material accumu...

Introduction: As recommended by World Health Organization, consumption of the fungal contaminated water does not cause to serious infection, but may lead to healthy or aesthetic problems. The aim of this research was to assess the occurrence of fungi in water and its relationship with fecal indicator bacteria. Materials and Methods: 110 water samples were collected from different location of w...
