【摘要】 本文研究了必需元素Zn及非必需元素Ph对菲律宾蛤仔（Ruditapesphilippinarum）的急性毒性作用，得到Zn对其的48hLD50和96hLD50分别为147.91、16．40mg／m3；Ph对其的48hLD50和96hLD50分别为31．62、14．28mg／dm3。估算得到Zn、Ph对菲律宾蛤仔的安全浓度分别为082、0.71mg／dm3。更多还原

【Abstract】 Acute toxicity of zinc and lead to Ruditapes philippinarum was studied. Toxicity of Zn2+ and Pb2+ was evaluated in 48 h and 96 h bioassays. The 48 h LD50 values were 147. 91 mg/dm3 for Zn2+ and 31. 62 mg/dm3 for Pb2+ ; the 96 h LD50, values were 16. 40 mg/dm3 for Zn2+ and 14. 28 mg/dm3 for Pb2+. Thg safe concentration of Zn2+ and Pb2+ for Ruditapes philippinarum was also estimated, to be 0. 82 mi/dm3 and 0. 71mg/dm3 respectively.更多还原
