ABSTRACT The study has been conducted with inductively coupled plasma optical emission spectrometry to determine the content of toxic heavy metals, macroelements, and essential elements in two species of bivalves of commercial interest in the Canary Islands: the Mediterranean mussel (Mytillus galloprovincialis, Lamarck 1819) and the razor clam (Ensis directus, Conrad 1883). The study included 40 samples corresponding to 20 specimens of each species acquired from fishmongers on the island of Tenerife. E. directus had higher levels of metals, except for B, Cd, Na, and Zn (0.98, 0.02, 2,006.93, and 15.07 mg/kg, respectively) compared with those in M. galloprovincialis, B, Cd, Na, and Zn (2.67, 0.12, 2,267.7, and 22.27 mg/kg, respectively). In both bivalve molluscs, the maximum limits established by European legislation on food for human consumption were not exceeded. Likewise, the estimated daily intakes for the toxic metals Pb and Cd were below the admissible daily intakes.

Nutritional drinks (NDs) are medicinal food products intended for people with different health issues constricting nutrients provision. Eight varieties of milkshake style NDs were analyzed in this work. Prior to element analysis, they were freeze-dried, and concentrations of twenty macro- and microelements in analyzed samples were simultaneously measured by ICP-OES after their mineralization in a closed-vessel microwave-assisted digestion system. Results of this analysis indicated that these NDs must be considered as nutrient-dense foods, taking into account mineral constituents. Consumption of two bottles of such NDs per day provides very a high amount or even an excess of human daily requirements set as Recommended Dietary Allowances (RDAs). Generally, concentrations of determined elements in examined NDs were consistent with data given on the labels—most of differences did not exceed 30% (median: −5.91%, standard deviation: 14%). Discovered very strong and moderate positive correlations between concentrations of major and essential elements (Ca, Mg, P, Cu, Fe, Mn, Zn) were likely due to their incorporation into formulations of analyzed NDs. However, relationships between contents of trace elements were the result of concomitance of these elements in substrates used for examined products production or contamination of substrates.
