Abstract The objective of the study is multi elemental analysis of four indigenous Ethiopian tuber crops using instrumental neutron activation analysis (INAA) technique in order to get scientific evidences about the status of essential, trace and non-essential elemental compositions. The samples were collected from Southern and South-western parts of Ethiopia. The irradiation and measurement were performed by using irradiation and counting facilities of the Nigeria Nuclear Reactor-1 (NIRR-1) and a HPGe detector setup at the Centre for Energy Research and Training (CERT), Ahmadu Bello University (ABU), Zaria, Nigeria. A total of 17 elements were determined at various concentration levels. The highest concentrations of K, Mg, Mn and Zn were found in Colocasia esculenta (L.) Schott, whereas; the concentrations of essential and trace elements; Ca, K, Mg, Na, Cl, Mn, and Zn were found to be high in the native Coccinia abyssinica (Lam.) Cogn tuber. The estimated daily intake values of the constituent elements from the consumption of these crops are below upper tolerable limits set by international organizations such as WHO and FAO.

Fruits and vegetables constitute the cheapest source of essential trace elements for the majority of people living in developing countries. The Cu, Fe and Zn contents in twenty selected wine samples produced in the South-East region of Serbia were determined by flame atomic absorption spectrometry. The Cu concentrations varied from 0.07 to 0.57 ppm in wines, and the Fe concentrations fluctuated from 2.93 to 36.2 ppm, while the Zn levels were in the range from 0.21 to 0.67 ppm. The established contents of Cu and Zn showed that wines from this part of the world could serve as good dietary sources of the essential trace metals, and the determined values were within the allowed metals levels in wines for human consumption.

A new analytical method based upon the combination of Pulsed UV (PUV) photolysis and detection of elements via X-ray fluorescence (PIXE and XRF) techniques has been developed and shown capable of rapid and reproducible trace element analyses with increased sensitivity in solid and liquid foods. Pulsed UV-induced photolysis allows for a rapid, acid-free digestion of food samples. Thin or thick samples are then prepared for analyses with X-Ray Fluorescence methods (PIXE and XRF). The combined method was optimized for analysis of Co , Cr , Cu , Fe , Pb , Tl , Bi and Zn , and validated with NIST food standards. The analytical sensitivity of the PUV/PIXE/XRF method allows the study of selected sections of fruits and vegetables, a database useful in determining the uptake, transport mechanisms, and the distribution of trace elements in fresh produce. When applied to edible parts, the analytical results shall also provide valuable information to ascertain potential human health risks due to the presence and bioaccumulation of toxic elements in foods. Practical applications include field studies for analyses of fresh produce as well as for evaluating environmental impact derived from current agricultural practices. Chemical profiling of agricultural crops and soils for improved management and increased productivity using the precision agriculture approach is also being explored.
