摘要

地表水中的环境本底浓度在欧洲指导文件中被称为天然本底浓度 (NBC)，在评估天然生成物质时，它可能是决定监测点是否符合具有法律约束力的环境质量标准 (EQS) 的一个重要因素。在此，我们将重点放在利用常规监管地表水监测数据，为风险评估人员和环境从业人员提供一种透明、可实施、可重复且资源有效的方法来估算 NBCs。该方法不使用常规环境采样以外的额外环境采样，也不需要先进的统计方法，也不需要纳入高度专业的、并非总能随时获取的当地知识。该方法采用 11 项标准来确定一个地点是否适合进行核生化评估，以及确定合适的替代地点和当地核生化水平：其中 6 项标准用于确定一个地点是否适合进行核生化校正，5 项标准用于确定当地核生化值的合适替代地点。这些标准考虑了任何 EQS 超标的程度（根据欧洲指南考虑生物可利用性后）以及该地点的潜在人为影响，并可按简单的顺序应用。该方法已被用于推导三个案例研究国家（塞浦路斯、法国和西班牙）的镍的核生化指示值，以确定其可用性和对合规性的影响。所介绍的方法解决了当前指南中有关切实、一致地实施 NBC 的空白，并可应用于 EQS 或水质指南合规性评估过程中的其他天然物质。Integr Environ Assess Manag 2024;00:1-14。© 2024 WCA 环境有限公司和 NiPERA 公司。综合环境评估与管理》由 Wiley Periodicals LLC 代表环境毒理学与化学学会 (SETAC) 出版。

Practical estimation and use of natural background concentrations in surface waters for nickel in Europe

Estimates of ambient background concentrations in surface waters, referred to as natural background concentrations (NBCs) in European guidance documents, may be an important factor in determining whether a monitoring site meets the legally binding Environmental Quality Standard (EQS) when assessing naturally occurring substances. Here, we focus on utilizing routine regulatory surface water monitoring data to provide risk assessors and environmental practitioners with a transparent, implementable, repeatable, and resource-effective approach to estimate NBCs. The methodology does not use additional environmental sampling beyond that which is routine or require advanced statistical methods, or the incorporation of highly specialist, and not always readily accessible, local knowledge. It determines both whether a site is suitable for NBC assessment as well as the identification of suitable surrogate sites and local NBCs using 11 criteria: six for identifying if a site is suitable for NBC correction, and five for identifying suitable surrogate sites for local NBC values. The criteria consider both the extent of any EQS exceedance, after accounting for bioavailability in line with the European guidance and potential anthropogenic impacts at the site, and can be applied in a simple sequential procedure. The method has been applied to derive NBCs for nickel on three case-study countries—Cyprus, France, and Spain—to determine its useability and impact on compliance. The methodology presented addresses a gap in the current guidance regarding the practical and consistent implementation of NBCs and could be applied to other naturally occurring substances in an EQS or Water Quality Guideline compliance assessment process.

期刊介绍： Integrated Environmental Assessment and Management (IEAM) publishes the science underpinning environmental decision making and problem solving. Papers submitted to IEAM must link science and technical innovations to vexing regional or global environmental issues in one or more of the following core areas: Science-informed regulation, policy, and decision making Health and ecological risk and impact assessment Restoration and management of damaged ecosystems Sustaining ecosystems Managing large-scale environmental change Papers published in these broad fields of study are connected by an array of interdisciplinary engineering, management, and scientific themes, which collectively reflect the interconnectedness of the scientific, social, and environmental challenges facing our modern global society: Methods for environmental quality assessment; forecasting across a number of ecosystem uses and challenges (systems-based, cost-benefit, ecosystem services, etc.); measuring or predicting ecosystem change and adaptation Approaches that connect policy and management tools; harmonize national and international environmental regulation; merge human well-being with ecological management; develop and sustain the function of ecosystems; conceptualize, model and apply concepts of spatial and regional sustainability Assessment and management frameworks that incorporate conservation, life cycle, restoration, and sustainability; considerations for climate-induced adaptation, change and consequences, and vulnerability Environmental management applications using risk-based approaches; considerations for protecting and fostering biodiversity, as well as enhancement or protection of ecosystem services and resiliency.
