This standard replaces GB/T 16125-1995 "Daphnia magna test standard method", compared with the GB/T 16125-1995 main technical change Of the following. --- The original standard name "Daphnia magna test standard method" to "Daphnia magna acute toxicity test methods"; --- Original standard subject matter and scope of application to modify the scope and removes Daphnia growth and reproduction of experimental methods (chronic effects); --- According to GB/T 1.1-2009 restructured, supplemented with "normative references", "Terms and Definitions"; --- The standard 4.2 adds definition and formulation methods standard dilution water; --- Increased 6.1 This standard sample collection and preservation methods; --- The standard 7.1 increase in the content and the limits of experimental methods; --- This standard adds quality control and quality assurance of content and methods; --- Original Standard Appendix A Appendix A to adjust "culture propagation method Daphnia magna" and Appendix B "Scenedesmus obliquus culture techniques." The use of standard reference redrafted ISO 6341.1996 "Quality - Daphnia magna (Crustacea, Cladocera) activity inhibition assay" establishment, And ISO 6341.1996 is non-equivalent. This standard is proposed and administered by the People's Republic of China Ministry of Health. This standard was drafted. Chinese Center for Disease Control Environmental Health and Related Product Safety. The main drafters of this standard. Liu Fan, Pan Lijun, high Shirong, Wang Jun together.
