Steel slag is being used worldwide for a variety of applications, among which is underwater dyke reinforcement. In the present study the leaching and bioaccumulation of 18 inorganic compounds from basic oxygen furnace (BOF) steel slag were monitored in marine experimental ecosystems (mesocosms) for 12 wk. Triplicate mesocosms were installed at 2 refreshment rates, one reflecting the situation in the Oosterschelde estuary where BOF steel slag was applied and the other at a 35 times lower rate. Vanadium in both water and biota turned out to be the best tracer for the presence of BOF steel slag in the mesocosms. The mesocosm data helped to interpret the results of a 4-yr field sampling program in the Oosterschelde estuary where no elevated levels of vanadium in water or biota were found near locations where steel slag was applied. Also, no ecological impact could be established in the field, which was in line with the observations in the mesocosms. The present study shows the added value of a tailor-made mesocosm study for realistic risk assessment and provides support for applying this tool as a basis for designing efficient field monitoring programs. Environ Toxicol Chem 2021;40:2499–2509. © 2021 The Authors.

钢渣中金属的浸出及其对海洋生态系统的生态影响：利用中宇宙观测验证现场数据

钢渣在世界范围内被用于各种应用，其中包括水下堤坝加固。在本研究中，在海洋实验生态系统（中宇宙）中监测了 18 种无机化合物从碱性氧气炉 (BOF) 钢渣中的浸出和生物积累 12 周。以 2 种刷新率安装了三次中宇宙，一个反映了 Oosterschelde 河口的情况，其中使用了 BOF 钢渣，另一个以低 35 倍的速度安装。水和生物群中的钒被证明是中宇宙中 BOF 钢渣存在的最佳示踪剂。中宇宙数据有助于解释在 Oosterschelde 河口进行的为期 4 年的现场采样计划的结果，在该河口，在使用钢渣的位置附近没有发现水中或生物群中钒含量升高。还，在该领域无法确定生态影响，这与中宇宙的观察结果一致。本研究显示了量身定制的中宇宙研究对现实风险评估的附加价值，并为应用该工具作为设计有效现场监测计划的基础提供了支持。 环境毒物化学2021；40:2499–2509。© 2021 作者。Wiley Periodicals LLC 代表 SETAC 出版的Environmental Toxicology and Chemistry 。
