Determination of Elemental Composition of Malabar spinach, Lettuce, Spinach, Hyacinth Bean, and Cauliflower Vegetables Using Proton Induced X-Ray Emission Technique at Savar Subdistrict in Bangladesh

Abstract EN

The concentrations of 18 different elements (K, Ca, Fe, Cl, P, Zn, S, Mn, Ti, Cr, Rb, Co, Br, Sr, Ru, Si, Ni, and Cu) were analyzed in five selected vegetables through Proton Induced X-ray Emission (PIXE) technique.

The objective of this study was to provide updated information on concentrations of elements in vegetables available in the local markets at Savar subdistrict in Bangladesh.

These elements were found in varying concentrations in the studied vegetables.

The results also indicated that P, Cl, K, Ca, Mn, Fe, and Zn were found in all vegetables.

Overall, K and Ca exhibited the highest concentrations.

Cu and Ni exhibited the lowest concentrations in vegetables.

The necessity of these elements was also evaluated, based on the established limits of regulatory standards.

The findings of this study suggest that the consumption of these vegetables is not completely free of health risks.
