  1. Characterization of the regional distribution of selenium in Chile using selenium in Hen's eggs as a monitor.

    Article - En anglais

    Regional distribution of selenium (Se) in Chile was investigated by using the concentration of Se in hens'eggs as a monitor.

    Forty-one locations along the entire lenght of the country were sampled.

    Average (±SD) egg-white Se content (mg/kg dry) was 0.79 ± 0.41, range 0.22-2.23.

    Corresponding yolk Se values were, mean 0.81 ± 0.43, (mg/kg dry) range 0.26-2.23.

    Locations grouped in five main areas, according to their geographic-climatic characteristics, showed significant differences regarding both egg-white Se and yolk Se.

    Analyzed dietary Se intake from two distinct areas reflected the trends observed in the Se content of egg fractions from such regions.

    These data support the utilization of the concentration of Se in hens'eggs as a useful monitor of dietary selenium consumed by selected populations.
