1.1 本规程描述了用甲醛、乙醇、戊二醛、卢戈尔碘溶液或醋（乙酸）保存浮游动物样本的正确程序。 1.2 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 5.1 碳酸钙（CaCO 3. )缓冲福尔马林（3 % 至5 %) 可作为浮游动物的永久防腐剂。卢戈尔的碘溶液可用于保护浮游动物长达一年。 30%乙醇，30 % 戊二醛，或25 % 醋（可以用3 % 乙酸溶液）可以用于浮游动物样品的更多临时存储和保存。A 25 % 醋溶液更适合保存软体浮游腔肠动物。

1.1 This practice describes the proper procedures for preserving zooplankton samples with either formaldehyde, ethanol, glutaraldehyde, Lugol’s iodine solution, or vinegar (acetic acid). 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 Calcium Carbonate (CaCO 3 ) buffered formalin (3 % to 5 %) can be used as a permanent preservative for zooplankton. Lugol’s iodine solution can be used to preserve zooplankton for up to one year. Thirty percent ethanol, 30 % glutaraldehyde, or 25 % vinegar (can use 3 % acetic acid solution) can be used for more temporary storage and preservation of zooplankton samples. A 25 % vinegar solution is preferred to preserve soft-bodied planktonic coelenterates.
