fluoride is one of the most important elements in the composition of teeth and bones. this element can enter the body via different ways. however, drinking water is the most important way to receive fluoride by a lot of people. an increase in fluoride level in the body causes dental fluorosis and its absence leads to teeth decay. standard rate of fluoride in drinking water is determined by the ...

this study was carried out to investigate the effect ofadministration of satureja khuzistanica essential oil (skeo) in drinking water on performance, lipid oxidation, activity of antioxidative enzymes and cholesterol content of thigh meat using 720 one-day-old ross 308 broiler chicks. the skeo was added into drinking water at zero (control-), 200, 300, 400 and 500 mg/l along with a treatment co...

There is a growing discussion about the possibility of arsenic mitigation measures in Bengal and similar areas leading to undesirable substitution of water-borne-pathogen attributable risks pathogens for risks attributable to arsenic, in part because of uncertainties in relative pathogen concentrations in supplied and end-use water. We try to resolve this discussion, by assessing the relative c...

fluoride is an essential element for human health. however, excess fluoride in drinking water may cause dental and/or skeletal fluorosis. drinking water is the main route of fluoride intake. the aim of the present study was to measure fluoride levels in human breast milk collected from two regions of golestan province, northern iran with different amount of fluoride concentration of drinking wa...

Water provision for developing countries is a critical issue as a vast number of lives are lost annually due to lack of access to safe drinking water. The presence and fate of inorganic trace contaminants is of particular concern. Trace inorganic contaminants have been found in elevated concentrations in drinking waters supplied directly from brackish groundwaters in developing countries. Desal...

Water-borne illness, primarily caused by fecal contamination of drinking water, is a major health burden in the state of Andhra Pradesh, India. Currently drinking water is treated at the reservoir level and supplied on alternate days, necessitating storage in households for up to 48 hrs. We hypothesized that fecal contamination occurs principally during storage due to poor water handling. In th...

OBJECTIVE To measure the association between the disinfection of municipal drinking water with monochloramine and the occurrence of hospital-acquired legionnaires' disease (LD). SETTING One hundred sixty-six U.S. hospitals. DESIGN Survey of 459 members of the Society for Healthcare Epidemiology of America (SHEA) for hospital features; endemic- and outbreak-related, hospital-acquired LD; the...

background: many radioactive compounds may be released into the environment and hence into the drinking water supplies due to the human activities. radionuclides can also enter the food chain if the contaminated water is used for drinking or irrigation purposes. objective: to estimate the annual effective dose of natural radioactive materials like 226ra and 40k in drinking water of wells in zan...
