[Consumption of drinking water by workers in a steel foundry during working hours in Hungary].
In a former paper the authors had investigated the fluorine intake per kilogram body weight and its extreme possibilities. This study includes 97 workers of a steel foundry. The amount of liquid ingested during working hours was measured, for 30 persons in summer during 90 days and 67 persons in winter during 201 days. Inside and outside temperatures were recorded. The mean age was 40,02 years. The mean intake of drinking water was, in summer 3732 ml (+/- s 1176 and +/- sx 123 ml) and in winter 1835 ml (+/- s 684 and +/- sx 48 ml). The mean value was 2422 ml and the extreme values were 500 and 8500 ml. The calculation of the individual mean values showed however, that the water intake follows an irregular pattern of distribution. About 11% consumed more than 41, and about 2% more than 51 per day continuously. In this study, there are those who consume habitually little, more and a lot of drinking water. With the results, the authors are examining the possibilities of the maximum fluorine intake.
