PIXE technique was applied to measurement of trace elements in total diet samples collected in Japan for estimation of their daily dietary intake. Results of PIXE analysis were compared with INAA Concentration of Cl, K, Mn and Zn by PIXE analysis well agreed with the results from NAA, while Ca, Fe and Cu showed different results between these two techniques. Preliminary data of elemental concentrations in Mate-cha, a kind of tea popular in South America, determined by ICP-AES indicated a little higher concentration of Cu than that by PIXE and much lower value than that by INAA For Zn. concentrations by PIXE and ICP well agreed to each other, while INAA gave much lower value. Japanese internal radiation doses by 137 Cs and 90 Sr were estimated to be 2.30µSv/year and 1.27µSv/year respectively as the effective dose equivalents using the daily intake data obtained for K and Ca.

Mineral trace element concentration of human saliva from healthy volunteers, were investigated by Proton-Induced X-ray Emission (PIXE) analysis. The specimens were bombarded with Proton beams of 2 MeV from a Van de Graaff accelerator at NRC . The object of this measurement was to find a normal range of trace element concentration for Iranian people.

The purpose of this study is to analyze quantitatively trace elements in human organs without decomposing samples. A palladium thin layer was deposited onto a sample on carbon adhesive tape using a metal ion sputtering equipment. The Pd film was used as an internal standard to determine concentrations of trace elements in human liver. Bovine Liver was applied as the reference standard. Five elements Cu , Zn , Mn , Se and Fe were measured by this method. The values of Copper, Zinc and iron concentrations determined by PIXE using this method agree well with those by ICP-AES. It can he asserted that this method is quite useful in the study of non-destructive PIXE analysis.

Trace element concentrations in short necked clam Ruditapes philippinarum marked shells with iron rusting were determined by particle induced X-ray emission (PIXE) method. Element such as Ca, Mn, Fe, Zn, Sr, and Br were detected in the shells. The Fe/Ca X-ray intensity ratio decreased exponentially on the day after marking. It was concluded that the higher Fe concentration on marked clams was caused by attached iron rusting. The concentrations of Fe, Br, and Sr differed among the 3 stations (Kamaya, Shigaki, and Iwatani), suggesting that elemental concentrations may be related to the growth of clams.

Trace elements are known to have pivotal role in human health and disease. Present investigation employed PIXE analysis to probe into the elemental profile of patients suffering from visceral Leishmaniasis. Remarkable alterations were observed in concentration of elements like Cl , K , Ca , Mn , Fe , Cu , Zn . The pattern of enhancement of elemental concentration corresponds to the progression of the disease. Additionally, our present data reflect probable correlation between alteration in trace elemental status and other pathological syndromes associated with Leishmaniasis. The possibility of considering trace elements as a diagnostic marker for a better understanding of the disease is discussed.
