European legislative framework supports a multidisciplinary strategy of environmental monitoring because the environment is a complex system of abiotic and biotic interactions, and it should not be studied and protected by looking at one single aspect. The resulting heterogeneous data request to be carefully processed, and the application of Weight of Evidence (WOE) approaches is, thereby, an integrated validated tool. In this perspective, the present study aims to: (i). apply a specific model (Sediqualsoft) based on the WOE approach for processing multidisciplinary data related to four Lines Of Scientific Evidence (LOEs: chemical analyses, ecotoxicological bioassays, bioaccumulation tests and biomarkers) regarding sediments from an area of the Adriatic Sea; (ii). evaluate the usefulness of this specific integrated approach to estimate the potential environmental hazard due to the presence of gas production platforms respect to the traditional approach of sediment chemical characterization. This latter recognized a more contaminated area within 100 m of the platforms in which the Sediqualsoft model showed the presence of a chemical hazard, ranging from moderate to severe, and identified the contaminants (e.g., some metals, benzo(a)pyrene and acenaphthene) most responsible for it. A significant hazard also appeared in some of the sampled stations by analyzing the LOEs dedicated to the biological responses. The choice of different reference values (regulatory limits, threshold values or concentrations measured in the control area) influenced only the chemical hazard but not the overall integration with other LOEs, showing a moderate hazard for the majority of stations. Here, the concentrations measured in a control area are firstly proposed as possible reference values in Sediqualsoft model applications; this could be of particular relevance when Sediment Quality Guidelines are not available for all the measured substances. Moreover, the limitations of a conventional pass-to-fail approach or worst-case scenario were overcoming interpreting whole chemical and ecotoxicological results. All data analyzed and discussed confirm Sediqualsoft as a suitable tool for processing environmental data, including those first processed here on a monitoring scenario of gas platforms that discharge Produced Water into the sea.

评估亚得里亚海近海平台区海洋沉积物环境危害的证据权重 (WOE) 方法

欧洲立法框架支持环境监测的多学科战略，因为环境是一个非生物和生物相互作用的复杂系统，不应通过单一方面来研究和保护环境。由此产生的异构数据请求需要仔细处理，证据权重 (WOE) 方法的应用因此是一个集成的验证工具。从这个角度来看，本研究旨在：（i）。应用基于 WOE 方法的特定模型 (Sediqualsoft)，处理与亚得里亚海区域沉积物有关的四条科学证据线（LOE：化学分析、生态毒理学生物测定、生物积累测试和生物标志物）相关的多学科数据；（二）。相对于传统的沉积物化学表征方法，评估这种特定的综合方法在估计由于天然气生产平台的存在而导致的潜在环境危害方面的有效性。后者识别出平台 100 m 内污染更严重的区域，其中 Sediqualsoft 模型显示存在化学危害，范围从中度到重度，并识别出污染物（例如，某些金属、苯并 (a) 芘和苊）对它最负责。通过分析专用于生物响应的 LOE，一些采样站也出现了重大危害。选择不同的参考值（监管限制、控制区测量的阈值或浓度）仅影响化学危害，但不影响与其他 LOE 的整体整合，显示大多数站点的中等危害。在这里，在控制区域中测量的浓度首先被提出作为 Sediqualsoft 模型应用程序中可能的参考值；当沉积物质量指南不适用于所有被测物质时，这可能特别重要。此外，传统的通过到失败方法或最坏情况的局限性正在克服对整个化学和生态毒理学结果的解释。分析和讨论的所有数据都证实 Sediqualsoft 是处理环境数据的合适工具，包括在此处首先在将采出水排放到海中的天然气平台监测场景中处理的数据。
