Direct Toxicity Assessment of flowback waters from Beetaloo Sub-basin

\n## **Abstract** \nThe dataset was compiled by the Geological and Bioregional Assessment Program from multiple sources referenced within the dataset and/or metadata. Supporting information is provided for the direct toxicity assessment (DTA) conducted on flowback waters from two exploratory wells in the Beetaloo Sub-basin, Northern Territory, Australia. The data consists of the chemical characterisation (physico-chemistry, inorganics, organics and radionuclides) of the flowback waters, major ion analysis of the dilution waters used in the DTAs and the methods of chemical analysis. Details of the test methods and diluent composition used in the DTA are given as well as the toxicity data and physicochemical data from the DTAs. Statistical parameters of the comparisons made between the species sensitivity distributions derived from DTA with the flowback waters and respective salinity controls are given.\n\n\n## **Attribution** \nGeological and Bioregional Assessment Program\n\n\n## **History** \nChemical characteristics of the flowback and dilution waters were generated with chemical analytical techniques. Direct Toxicity Assessment data were generated using referenced standardised protocols.

## **摘要**
本数据集由地质与生物区域评估计划（Geological and Bioregional Assessment Program）基于数据集内部及/或元数据中引用的多源资料汇编而成。本数据集为针对澳大利亚北领地比塔卢次盆地（Beetaloo Sub-basin）两口探井返排液开展的直接毒性评估（Direct Toxicity Assessment, DTA）提供配套支撑资料。数据集内容涵盖返排液的化学表征数据（包括物理化学特性、无机成分、有机成分及放射性核素）、直接毒性评估所用稀释水的主要离子分析结果，以及化学分析方法细节；同时收录了直接毒性评估所采用的试验方法与稀释剂组成细节，以及各次直接毒性评估得到的毒性数据与物理化学数据。此外还提供了基于返排液直接毒性评估所得物种敏感性分布，与对应盐度对照组所得分布进行比对的统计参数。
