标准范围

ISO/TS 20281:2006提供了用于标准化生态毒性试验数据分析的统计方法指南。它侧重于获得参数统计估计的统计方法。所述方法旨在涵盖实验室生态毒性试验（水生、沉积物和/或陆地试验），也可能与其他毒性试验相关。针对不同的数据类型（定量、连续和离散数据，对应于死亡率、生长或繁殖），讨论了假设检验、浓度响应模型和基于生物学的模型。此外，还对实验设计提供了一些指导。尽管主要重点是向实验者提供帮助，但次要目标是帮助负责评估毒性试验的人员。最后，ISO/TS 20281:2006通过提供有关实验设计和统计分析问题的信息，可能有助于制定新的毒性试验指南。

ISO/TS 20281:2006 offers guidance on statistical methods used for the analysis of data of standardized ecotoxicity tests. It focuses on statistical methods for obtaining statistical estimates of parameters. The methods described are intended to cover laboratory ecotoxicity tests (aquatic, sediment and/or terrestrial tests), and may also be relevant for other toxicity tests.Hypothesis testing, concentration-response modelling and biology-based modelling are discussed for the different data types (quantal, continuous and discrete data, corresponding to mortality, growth or reproduction). In addition, some guidance on experimental design is given. Although the main focus is on giving assistance to the experimentalist, a secondary aim is to help those who are responsible for evaluating toxicity tests. Finally, ISO/TS 20281:2006 may be helpful in developing new toxicity test guidelines by giving information on experimental design and statistical analysis issues.
