Evidence gathered under the Defra-group investigation into Crustacean Mortality of Autumn 2021

Data and written reports detailing the evidence used to inform the Environment Agency and Defra-group investigation into Crustacean Mortality events of October 2021. Data from the Environment Agency comprise measurements of ~1500 chemical pollutants in sediment, water and biota (Crustacea spp) samples using a Gas Chromatography Mass Spectrometry (GC/MS) screening technique. Reports from Cefas comprise specific reports detailing a) statutory reporting of disease screening by the Fish Health Inspectorate, b) assessment of parasites in Hommarus gammarus, c) opportune microtoxicity testing of sediment samples collected from disposal sites in the Tees Bay in 2021, and d) all other components of the investigation that Cefas were involved in, including the modelling of sediment disposal, the modelling of chemical release of pyridine, and the assessment of evidence for a harmful algal bloom.

本数据集包含详尽的数据与书面报告，这些报告详细阐述了用于向环境署及Defra集团提供信息、以调查2021年10月发生的甲壳类动物死亡事件的证据。环境署提供的数据包括使用气相色谱-质谱联用（GC/MS）筛选技术对沉积物、水及生物（甲壳类动物物种）样本中约1500种化学污染物进行的测量。Cefas的报告包括特定报告，详细说明了以下内容：a) 鱼类健康检查局进行的疾病筛查的法定报告，b) 对Hommarus gammarus中寄生虫的评估，c) 2021年从蒂斯湾处置场收集的沉积物样本的适时微毒性测试，以及d) Cefas参与的调查的所有其他组成部分，包括沉积物处置建模、吡啶化学释放建模以及对有害藻华证据的评估。
