The ALA-D activity, haemoglobin content and growth was studied in the water flea, Daphnia magna, exposed to 0, 0.1, 0.2, 0.4, 0.8 and 1.6 micrograms Cd/l. The ALA-D activity in water fleas exposed to 0.2-1.6 micrograms Cd/l fluctuated around the control value. The activity in animals exposed to 0.1 micrograms Cd/l decreased during the entire experiment. After 16 days exposure to cadmium the haemoglobin content in water fleas ranged between 80 and 31% of control value. In animals exposed to 0.8 and 1.6 micrograms Cd/l the haemoglobin content decreased progressively during the experiment. Growth was not affected by cadmium at these concentrations.
研究了暴露于0、0.1、0.2、0.4、0.8和1.6微克镉/升环境中的大型溞的δ-氨基-γ-酮戊酸脱水酶（ALA-D）活性、血红蛋白含量和生长情况。暴露于0.2 - 1.6微克镉/升环境中的大型溞的ALA-D活性在对照值附近波动。暴露于0.1微克镉/升环境中的动物在整个实验过程中活性降低。镉暴露16天后，大型溞的血红蛋白含量在对照值的80%至31%之间。在暴露于0.8和1.6微克镉/升环境中的动物中，实验期间血红蛋白含量逐渐降低。在这些浓度下，生长未受镉的影响。
