Bioacumulación de zinc en cultivos y su contribución a la ingestión de Zn por la población cubana

Oscar Díaz Rizo, Susana Olivares Reumont, Otoniel Denis Alpízar

Resumen

Se reportan los contenidos de zinc y su bioacumulación en cultivos (arroz, vegetales y condimentos) procedentes de 18 áreas de agricultura urbana y suburbana. El contenido de zinc en los alimentos, así como en sus correspondientes suelos de cultivo, fue determinado por Fluorescencia de Rayos X y por Espectrometría de Absorción Atómica. La calidad del estudio se verificó mediante el análisis de los Materiales de Referencia Certificados IAEA 393 «Algae», MA-B-3/TM «Fish Tissue Lyophilised», IAEA V-10 «Hay» e IAEA Soil-7. Los resultados mostraron al arroz, de los cultivos estudiados, como el cultivo de mayor bioacumulación de zinc y como fuente importante de Zn en la dieta de nuestra población.

Palabras clave
