Trace metals intake of Nacella (P) magellanica from the Beagle Channel, Tierra del Fuego (Patagonia, Argentina)

摘要

With respect to cadmium, in 2010 the Joint FAO/WHO Expert Committee on Food Additives (JECFA) reviewed its preceding weekly intake evaluation (i.e. 7 μg kg~(-1) body weight) (WHO, 2006) after this paper was finished. The Committee (WHO, 2010) set the cadmium provisional tolerable monthly intake (PTMI) of 25 μg kg~(-1) b.w. which implies to a weekly intake of 5.8 μg kg~(-1) b.w. Thus, for an average adult (i.e. 65 kg) no more than 377 μg of cadmium per week is recommended. Considering the average concentration of cadmium found for N. magellanica samples in the Beagle Channel (5.42 μgg~(-1) whole tissue), the consumption of about 339 g (wet weight) of molluscs should be enough to reach the safety level.
