2005年4月,以在浙江舟山普陀兴海养殖优质种苗选育研究所取得的三疣梭子蟹各期溞状幼体作为实验动物,开展了Hg2+、Cu2+、Zn2+、Cr6+4种重金属离子对其急性毒性实验.结果表明:三疣梭子蟹幼体对重金属的耐药性均随实验时间延长而明显降低,4种重金属离子对三疣梭子蟹各期幼体的毒性大小依次为Hg2+、Cu2+、Zn2+、Cr6+,三疣梭子蟹苗种培育中对Cu2+、Hg2+、Zn2+、Cr6+的安全质量浓度取值分别为0.015 6 mg/L、0.002 5 mg/L、0.068 6 mg/L和0.523 0 mg/L.
In April 2005, Hg2 +, Cu2 +, Zn2 +, Cr6 + 4 heavy metal ions were harvested from each of the three species of Portunus trituberculatus obtained from Putongxinghai breeding high-quality seedling breeding research institute in Zhoushan, Zhejiang Province Acute toxicity test.The results showed that the tolerance of heavy metals in Portunus trituberculatus to Hg2 +, Hg2 +, Zn2 +, Cr6 +, Hg2 +, Hg2 +, Hg2 +, Hg2 +, Hg2 + The safety quality concentrations of Cu2 +, Hg2 +, Zn2 +, and Cr6 + in the culture of Portunus tritubus were 0.015 6 mg / L, 0.002 5 mg / L, 0.068 6 mg / L and 0.523 0 mg / L, respectively.
