(1) The Authors evaluate some parameters relative to the concentration of fluoride in the potable water and in that bottled available in the territory of the Ussl no.
(2) Relating to these results in the first step the development of a theoretical model concerning the different influencing factors (quality of water tubes and other devices, variation of temperature, quality of potable water and the effect of ionic exchangers, indirect contamination by patients and dental staff, nature of dental treatment, utilization frequency of the direct handpieces) appears to be necessary.
(3) The significant association of cases with exposure to the potable hot water supply, and the identification of case and potable water isolates of the same subtype, suggest that the potable hot water was responsible for transmission of disease in this outbreak.
(4) The study results indicate that pigmented bacteria could readily be detected by using plate counting media developed for heterotroph enumeration in potable waters with incubation periods of 7 days.
(5) Longterm gains in this area require attention to behavioral and community development issues, including reduction of the sex and parity related differentials in mortality, enhancement of the status of women, improved female literacy and employment opportunities, improved intrafamilial food distribution patterns, maternity benefits, provision of potable water, intersectoral development to strengthen health care delivery, increased community participation, expanded health services, and enhancement of the pace of development.
(6) Naturally contaminated water can be rendered potable by incubation with cordials at room temperature for 1 h. This may be a way to reduce the risk of water-borne diarrhoea, particularly where the cleanliness of drinking waters cannot be otherwise assured, for example when making up oral rehydration fluids and for travellers in high-risk areas.
(7) L. pneumophila serogroups 1 and 10 were also isolated from the hot potable water supply in the building to which 19 of the 21 patients had been admitted.
(8) Potable water solutions of the salts are diluted with buffer (pH-4) and quantified directly by SPF.
(9) There was a significant association between some risk factors such as: living with cats, ingestion of non potable water and ingestion of raw meat.
(10) To investigate the gastrointestinal effects of employing recycled water as an irrigation source for urban public parks, we studied subjects active in parks irrigated with potable water, nonpotable water of wastewater origin, and nonpotable water of runoff origin.
(11) In this study, various insecticidal and molluscicidal compounds were tested in the laboratory for their toxicity to the intermediate hosts, namely, various species of cyclops, which often live in sources of potable water, such as step-wells, cisterns and ponds.
(12) Recommendations for prevention are intensified surveillance throughout the year,urgent upgrading of potable water supply and concerted effort in public health education especially against the use of river water and the consumption of raw food.
(13) The reservoir for hospital-acquired Legionnaires disease has been shown to be the potable water distribution system.
(14) The lack of potable water and sanitation facilities contributes to the spread of disease and higher infant mortality.
(15) In the United States chlorination of potable water supplies has been the standard method of disinfection for about 75 years.
(16) A contaminant in groundwater represents a threat to a drinking water source but not necessarily a threat to health, if the contaminant's concentration is decreased before it becomes available as potable.
(17) In regions with low fluorine levels in potable water antenatal caries prevention with fluorine preparations should be carried out.
(18) By means of programmed temperature and direct injection, quantitative measurements of 22 components in potable spirits can be simultaneously finished in 50 min.
(19) The strongest evidence has been the similarity of strains recovered from patients and from potable water and the cessation of outbreaks following institution of measures to eradicate Legionella from potable water systems.
(20) Hyperchlorination, raising hot water temperatures to greater than 55 degrees C, and replacing rubber gaskets are useful methods for controlling outbreaks of legionellosis traced to potable water systems but are not yet justified as routine preventative methods in the absence of such an outbreak.
