1.1本指南旨在协助补救项目团队，特别是生态风险评估人员，确定可用于在受污染现场进行筛选或复杂生态风险评估（ERA）的数据和信息选项。 1.2人类健康风险评估数据和信息选项的识别不在本指南的范围内。 1.3本指南旨在提供一份清单，用于确定数据和信息选项，并不建议ERA活动的具体行动方案。 1.4本指南介绍了生态风险评估的数据和信息选项，而不是验证或长期评估- 长期监测研究。 1.5本指南列出了ERA的许多常见数据和信息选项，但可能还有其他与任何特定站点相关的选项。 1.6本指南考虑了ERA的一个组成部分，即数据和信息选项的识别。已经制定了其他ASTM指南，例如指南 E1689 和 E1848 ，并正在开发中，以涵盖风险评估过程的其他组成部分。 1.7本指南不提供在定义数据收集选项后如何执行用于执行风险评估的任何分析程序的信息。 ====意义和用途====== 本指南具有重要意义，因为它解决了生态风险评估过程每个组成部分的数据和信息选项，包括筛选和复杂ERA。它概述了数据和信息选项，同时认识到生态风险评估可能侧重于实现特定的既定目标。本指南不代表美国环境保护局（USEPA）或任何其他监管机构对生态风险评估数据收集的观点。 本指南供承包商、行业、政府机构和大学负责在受污染现场进行生态风险评估的管理人员、科学家和技术人员使用。 它将用于指导生态风险评估的数据收集阶段。它将有助于开发概念性场地模型（见指南 E1689 )以及潜在评估和测量终点的识别（见指南 E1848 ). 虽然该清单旨在帮助规划ERA，但也可用于审查已完成的ERA。

1.1 This guide is intended to assist remedial project teams, specifically ecological risk assessors, in identifying data and information options that may be used to perform a screening or complex ecological risk assessment (ERA) at a contaminated site. 1.2 The identification of data and information options for human health risk assessment is outside the scope of this guide. 1.3 This guide is intended to provide a list for identifying data and information options and does not recommend a specific course of action for ERA activities. 1.4 This guide addresses data and information options for the ecological risk assessment, not verification or long-term monitoring studies. 1.5 This guide lists many of the common data and information options for ERA, but there may be others relevant for any particular site. 1.6 This guide considers one component of an ERA, that is, identification of data and information options. Other ASTM guides have been developed, for example, Guides E1689 and E1848 , and are being developed to cover other components of the risk assessment process. 1.7 This guide does not provide information on how to perform any of the analytical procedures used to perform a risk assessment once data collection options are defined. ====== Significance And Use ====== This guide is significant in that it addresses the data and information options of each component of the ecological risk assessment process, for both a screening and complex ERA. It outlines the data and information options while recognizing that an ecological risk assessment may be focused to achieve a particular stated goal. This guide is not intended to represent the views of the U.S. Environmental Protection Agency (USEPA), or any other regulatory agency, on data collection for ecological risk assessment. This guide is to be used by managers, scientists, and technical staff of contractors, industry, government agencies, and universities responsible for conducting ecological risk assessments at contaminated sites. It is to be used to guide data collection phases of the ecological risk assessment. It will assist in the development of the conceptual site model (see Guide E1689 ) and the identification of potential assessment and measurement endpoints (see Guide E1848 ). While it was written to assist in planning an ERA, the list also may be used in the review of a completed ERA.
