Mercury and selenium content in Otolithes ruber and Psettodes erumei from Khuzestan Shore, Iran.

In this paper the level of selenium and mercury is analyzed in edible part and liver of Psettodes erumei and Otolithes ruber two commercial fish in Persian Gulf. The average concentration of Hg and Se in edible parts of P. erumei was 0.077 ± 0.062 and 0.044 ± 0.018 (μg g(-1)ww), and in liver was 0.127 ± 0.122 and 0.132 ± 0.610 (μg g(-1)ww) respectively. In O. ruber, the average concentration of Hg and Se in edible parts was 0.348-0.27 and 0.06 ± 0.021 (μg g(-1)ww) and in liver was 0.176 ± 0.174 and 0.093 ± 0.022 (μg g(-1)ww), respectively. P. erumei has higher mean molar ratio Se/Hg (1.98) compared to O. ruber (0.88). © Springer Science+Business Media, LLC 2011
