SARABIA, O.; CARDENAS-CORONEL, W. G.  y  ACUNA-JIMENEZ, M.. Comparative study of the content of macrominerals, trace elements and heavy metals in fruits of Carica papaya L. by ICP- OES in the State of Colima, Mexico. Revista bio ciencias [online]. 2020, vol.7, e590.  Epub 18-Nov-2020. ISSN 2007-3380.  https://doi.org/10.15741/revbio.07.e590.

The present study aims to evaluate the content of macrominerals, trace elements and heavy metals in Carica papaya L. fruits. Sixty fruits were collected from local markets in all the municipalities of the state of Colima, six fruits per municipality. Papaya samples were digested by microwave assisted method, then analyzed by Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) to determine the content of Ca, K, Mg, Na, P, Fe, Ni, Cu, Zn, Mn, Be, Li, Al, Ba, Cd, Co, Cr, Pb, Sb, Se, Sn, Tl, and V.

Macromineral content was detected in a range from 157 to 2,741 mg kg-1 of fresh fruit according the following trend K>Na>Ca>Mg>P; trace element content presented the following order of decreasing concentration Fe>Cu>Li>Ni>Zn>Ba>Mn>Be. Not detected elements were Al, Co, Sb, Se, Sn, Tl, and V. Elements detected in low concentration were Cr, Pb and Cd, with mean values of 1.5±0.30, 0.35±0.15 and 0.16±0.15 mg kg-1 of fresh fruit, respectively.

Health risk assessment was performed due to the content of Cr, Pb and Cd detected in fruit samples. The calculated values of Dietary Intake of Metals (DIM) and Health Risk Index (HRI) were <1, and based on safety limits established by the World Health Organization (WHO), there are no health risk for papaya fruits commercialized in the State of Colima.
