dc.descriptionThe purpose of this study was to evaluate the total concentration levels of trace elements (Cr, Cu, Mn, Pb, Rb and Sr) in octopus' mantle and tentacles samples from Mexico City markets, by using the Mexican regulation applied to food for human consumption. The determination of both essential (Cr, Cu, Mn) and non-essential (Pb, Rb and Sr) trace elements was made by inductively coupled plasma-quadrupole mass spectrometry (ICP-QMS). The samples were collected from local markets and supermarkets from each of 16 delegations of Mexico City, Distrito Federal. The overall ranges of concentrations found were: 2.4-4.8, 5.1-95.3, 1-6, 0.1-1.6, 0.4-4.5 and 11-58 mg/kg for Cr, Cu, Mn, Pb, Rb and Sr, respectively. The maximum and mean concentration values obtained for Cu and Cr in mantle and tentacle samples from both kind of markets, are above of the NOM-051-SCFI/SSA1-2010 (closest Mexican standard), according to USDA National NDB for Standard Reference consumer exposure (100g/day) of octopus. It was observed that the maximum Pb concentration value found in mantle and tentacle samples from supermarkets origin exceeds the NOM-129-SSA1-1995 and NOM-242-SSA1-2009 reference values, while the maximum mean value is below the regulation. Similar Mexican regulation data for Mn, Rb and Sr were not found.
