The accumulations of Cd, Pb and Zn were determined in edible and inedible tissues of Persian sturgeon (Acipenser persicus; n=27), stellate sturgeon (Acipenser stellatus; n=5) and beluga (Huso huso; n=4) collected from coastal waters of the South Caspian Sea from March to April 2011. Concentrations of metals evaluated in the caviar, muscle, liver, kidney, gills, ovary and heart of the three species of sturgeons have been assessed using the flame and graphite furnace atomic absorption spectrophotometer. Concentrations of Zn, Pb and Cd in the edible and inedible tissues were apparently different among the three species of sturgeons. Especially, beluga heart showed the highest concentrations of Zn and Pb and Cd in Persian sturgeon liver. The analyzed metals were found in the caviar and muscle samples of Persian sturgeon and likewise muscle samples two other sturgeon species at mean concentrations under the permissible limits proposed by MAFF (2000).
于 2011 年 3 月至 4 月期间，从里海南部沿海采集了 27 尾波斯鲟（Acipenser persicus）、5 尾星斑川鲽（Acipenser stellatus）和 4 尾白鲟（Huso huso），并测定了可食用和不可食用组织中 Cd、Pb 和 Zn 的积累量。采用火焰原子吸收光谱法和石墨炉原子吸收光谱法评估了这三种鲟鱼的鱼子酱、肌肉、肝脏、肾脏、鳃、卵巢和心脏中金属的浓度。三种鲟鱼的可食用和不可食用组织中的 Zn、Pb 和 Cd 浓度明显不同。特别是，白鲟的心脏中 Zn 和 Pb 以及 Cd 的浓度最高，而波斯鲟的肝脏中这三种金属的浓度最高。在日本农林水产省（MAFF）（2000 年）提出的允许限量下，在波斯鲟的鱼子酱和肌肉样本以及另外两种鲟鱼的肌肉样本中均检测到了这些分析金属。
