The biomagnification of mercury and PCB153 was studied in experimental aquatic food chains involving three species of phytoplankton, one species of zooplankton and one species of fish. The phytoplankton species Ceratium furca, Ceratium tripos and Chaetoceros brevis were exposed to 0, 0.2, 0.5, 1.0 and 2.0 mg/l of Hg and 0, 0.5 and 2.0 mg/kg of PCB 153. Subsequently, each species was fed to the zooplankton Daphnia hyaline, which was then used as food for the fish Liza abu. The results indicated biomagnification of Hg and PCB153 in all three chains. Highest concentration of mercury was found in C. brevis and the highest concentration of PCB153 was observed in C. tripos. Accordingly, highest concentration of Hg and PCB 153 was found in D. hyaline and in the liver of L. abu belonging to food chains started from Chaetoceros brevis and Ceratium tripos respectively.
研究了汞和 PCB153 在涉及三种浮游植物、一种浮游动物和一种鱼类的实验性水生食物链中的生物放大作用。将角毛藻、三刺角毛藻和短角毛藻暴露于 0、0.2、0.5、1.0 和 2.0 mg/L 的汞和 0、0.5 和 2.0 mg/kg 的 PCB153 中。随后，将每种浮游植物喂给浮游动物透明溞，然后用透明溞喂养鱼类阿布丽。结果表明，汞和 PCB153 在所有三种食物链中都发生了生物放大作用。汞的最高浓度出现在短角毛藻中，而 PCB153 的最高浓度出现在三刺角毛藻中。相应地，汞和 PCB153 的最高浓度出现在透明溞和属于分别从短角毛藻和三刺角毛藻开始的食物链的阿布丽肝脏中。
