摘要: Stable carbon (δ13C) and nitrogen (δ15N) isotopic values total mercury (Hg) concentrations were analysed in muscle liver of mothers embryos two aplacental shark species, Squalus megalops Centrophorus moluccensis. Embryos the species had similar or lower than their respective mothers, only exception being for δ13C, which was higher C. moluccensis mothers. Hg systematically compared to suggesting a low transfer this element liver.
