Terrestrial enhanced rock weathering (ERW) is the application of pulverized silicate rock to soils for the purposes of carbon removal and improved soil health. Although a geochemical modeling framework for ERW in soils is emerging, there is a scarcity of experimental and field trial data exploring potential environmental impacts, risks, and monitoring strategies associated with this practice. This paper identifies potential negative consequences and positive cobenefits of ERW scale-up and suggests mitigation and monitoring strategies. To do so, we examined literature on not only ERW but also industry, agriculture, ecosystem science, water chemistry, and human health. From this work, we develop recommendations for future research, infrastructure, and policy needs. We also recommend target metrics, risk mitigation strategies, and best practices for monitoring that will permit early detection and prevention of negative environmental impacts.
陆地增强岩石风化（ERW）是将粉碎的硅酸盐岩石应用于土壤中，以达到去除碳和改善土壤健康的目的。尽管 ERW 在土壤中的地球化学建模框架正在出现，但缺乏探索与该实践相关的潜在环境影响、风险和监测策略的实验和野外试验数据。本文确定了 ERW 规模化的潜在负面影响和积极协同效益，并提出了缓解和监测策略。为此，我们不仅研究了 ERW 的文献，还研究了工业、农业、生态系统科学、水化学和人类健康的文献。在此基础上，我们为未来的研究、基础设施和政策需求提出了建议。我们还推荐了目标指标、风险缓解策略和监测最佳实践，以便早期发现和预防负面环境影响。
