Abstract

Phytoremediation is a technology that uses plants to break down, remove, and immobilize contaminants in surface water, shallow groundwater, and sediment to achieve cost savings compared with conventional treatments. This study describes a marshy land on an explosives manufacturing site in India that consistently reported elevated concentrations of nitrates, nitrites, ammonia, perchlorate, and lead (contaminants of potential concern—CoPC). The study also illustrates the potential for addressing the human health and environmental risks associated with the explosives manufacturing industrsy in India using innovative, sustainable, and carbon-neutral techniques. This work focuses on reconstructed marshy lands, desedimentation, microwatershed management, and phytoremediation using Phragmites and Vetiveria species (also known as vetiver) to reduce contaminants in surface water and groundwater, improve stormwater management and carbon capture, and increase natural capital like biodiversity. The results obtained during the trial indicate that the selected indigenous species are effective and can be used to remediate sediment and shallow groundwater for many CoPC in tropical climates.

利用植物修复技术恢复受潜在污染物污染的生态系统。

植物修复是一种利用植物分解、去除和固定地表水、浅层地下水和沉积物中污染物的技术，与传统的处理方法相比，可以节省成本。本研究描述了印度一个爆炸物生产基地的沼泽地，该沼泽地的硝酸盐、亚硝酸盐、氨、高氯酸盐和铅（潜在关注污染物--CoPC）浓度持续升高。这项研究还说明了利用创新、可持续和碳中和技术解决与印度炸药制造工业相关的人类健康和环境风险的潜力。这项工作的重点是重建沼泽地、沉积、微流域管理，以及利用苇草和香根草（又称香根草）进行植物修复，以减少地表水和地下水中的污染物，改善雨水管理和碳捕获，并增加生物多样性等自然资本。试验结果表明，所选的本地物种是有效的，可用于修复热带气候条件下的沉积物和浅层地下水。Integr Environ Assess Manag 2024;00:1-16。© 2024 SETAC.

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.
