que es el levitra For sustainable development, to assure health care services and for the protection of the human environment to ensure a quality of life, the knowledge of concentration on the environmental constituents is very much essential. In recent years the study of elements, both major and traces, especially related to environment has assumed increasing importance because of their vital role in human health and diseases. Fluorine is an essential element for both plant and animal life. A high incidence of caries has been shown by many investigators to be correlated with low fluorine inta:ke 6 •8•19. Excess intake of fluorine results in toxic symptoms described as fluorosis that causes many diseases like arthritis, Ia meness, pam. on movement, etc 6·1 71· 9-20 . The re,,..o re t h e concentratw. n o ffl uorm. e in drinking water is very important for human health. Nuclear analytical technique Proton Induced Gamma Emission (PIGE) method developed in the Van de Graaff Accelerator Laboratory of Atomic Energy Centre, Dhaka (AECD) was employed for the quantitative determination of fluorine in some water of Dhaka and its adjacent areas. Ion beam analysis technique PIGE was employed for the measurement of fluorinfi. because it is suitable and reliable for the analysis of fluorine content in water, b’i~a’il;e the determination of Fluorine is very difficult by non-ion beam techniques 5•18. The fluorine concentration in the drinking water of Dhaka ranges from 0.01 ppm to 0.46 ppm. The study indicates that the inhabitants of Dhaka have low intake of fluorine from their drinking water supplies.
