Pacific abalone, Haliotis discus hannai (mean length 2.92 ± 0.5 cm, and mean weight 2.63 ± 0.4 g) were exposed to different concentrations of waterborne nickel (0, 100, 200, and 400 μg/L) at 18, 22, and 26 °C for 2 weeks. The exposure concentration of Ni induced a significant Ni accumulation in specific tissues of H. discus hannai depending on water temperature. The order of nickel accumulation in tissues was hepatopancreas > gill ≈ digestive gland > muscle. Regarding antioxidant response indicators, the activity of superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH) in the hepatopancreas and gill tissues of H. discus hannai was significantly increased by the waterborne nickel exposure depending on water temperature. These results suggest that waterborne nickel exposure can induce a considerable nickel accumulation in specific tissues and stimulation of enzymatic antioxidant systems in Pacific abalone, H. discus hannai Ino, 1953 depending on water temperature.

太平洋鲍鱼，Haliotis discus hannai（平均长度2.92±0.5 cm，平均体重2.63±0.4 g）分别在18、22和26暴露于不同浓度的水性镍（0、100、200和400μg/ L） °C 2周。镍的暴露浓度取决于水温，导致在铁球菌特定组织中大量的镍积累。组织中镍的积累顺序是肝胰腺>腮≈消化腺>肌肉。关于抗氧化剂的反应指标，汉氏嗜血杆菌肝胰脏和g组织中的超氧化物歧化酶（SOD），过氧化氢酶（CAT）和谷胱甘肽（GSH）的活性根据水温的不同，水基镍的暴露会显着增加汞的含量。这些结果表明，水中的镍暴露可诱导特定组织中大量镍的积累，并刺激太平洋鲍鱼（H. discus hannai Ino，1953年）中的酶抗氧化剂系统，具体取决于水温。
