Metal content in caviar of wild Persian sturgeon from the southern Caspian Sea

摘要: Caviar (fish roe of sturgeon) may contain high levels contaminants. An inductively coupled plasma-optical emission spectrometer and a direct mercury analyzer were used to assess the contents four heavy metals (Hg, Se, Sn, Ba) in caviar wild Persian sturgeon sea foods. The Hg ranged from 1.39 1.50 μg g−1, Se 0.90 1.10 μg g−1, Sn 0.23 0.33, Ba 0.71 1.17 μg g−1. Evaluation these showed that except for Hg, average concentrations other are significantly lower than adverse level human consumption when compared with Food Agricultural Organization United Nations World Health permissible limits. Therefore, their contribution total body burden can be considered as negligibly small given is luxury product.
