摘要

A study of the trace elemental concentration in drinking water from Salt Lake City, a residential locality in Calcutta, India, was carried out using the proton induced X-ray emission (PIXE) technique. Samples were collected from overhead tanks, where drinking water is stored for supply to all parts of this residential area. A chelating agent (NaDDTC) was used for the pre-concentration of the trace elements. A large number of elements, namely Ca, Ti, Mn, Fe, Co, Ni, Cu, Zn, As, Sr, Ba, Tl and Pb were detected and the results are discussed.
