Abstract

DIAZ RIZO, Oscar et al. Bioaccumulation of zinc in crops and its contribution to Zn intake by Cuban population. Nucleus [online]. 2013, n.54, pp.8-11. ISSN 0864-084X.

Zinc content and Zn bioaccumulation in crops (rice and some vegetables and condiments) cultivated in 18 Cuban urban and suburban areas are reported. Zinc content in food and the corresponding farming soil samples was determined by X-Ray Fluorescence analysis and by Atomic Absorption spectrometry. The quality of the analysis was verified using the Certified Reference Materials IAEA 393 «Algae», MA-B-3/TM «Fish Tissue Lyophilised», IAEA V-10 «Hay» and IAEA Soil-7. The obtained results show rice, of the studied crops, as the major Zn bioaccumulator and important Zn source in Cuban human diet.

Keywords : Cuba; diet; biological accumulation; soils; crops; X-ray fluorescence analysis; absorption spectroscopy.
