纳米材料在环境修复中的潜在风险与管控策略 -环境工程专业

摘要

纳米材料因其独特的物理化学性质，在环境修复领域展现出广阔的应用前景，但其潜在的生态与健康风险也日益受到关注。本研究旨在系统评估纳米材料在环境修复中的风险特征，并提出针对性的管控策略。纳米材料的粒径、表面修饰及聚集状态显著影响其环境行为和毒性效应，且长期暴露可能引发不可逆的生态损害。基于此，本研究提出了涵盖全生命周期的风险评估框架，并设计了分级管理策略以降低潜在危害。创新点在于首次将动态风险评估模型引入纳米材料环境管理中，为制定科学合理的政策提供了理论依据。研究强调了跨学科合作的重要性，呼吁加强纳米材料的基础研究与监管体系建设，以实现环境修复效益的最大化与风险的最小化。这一成果为推动纳米技术可持续发展奠定了基础。

Abstract

Because of their unique physical and chemical properties, nanomaterials have shown broad application prospects in the field of environmental remediation, but their potential ecological and health risks are also increasingly concerned. The aim of this study was to systematically evaluate the risk characteristics of nanomaterials in environmental remediation and propose targeted management and control strategies. The particle size, surface modification and aggregation state of nanomaterials significantly affect their environmental behavior and toxic effects, and long-term exposure may lead to irreversible ecological damage. Based on this, this study proposes a risk assessment fr amework covering the whole life cycle and designs a hierarchical management strategy to reduce potential hazards. The innovation point is that the dynamic risk assessment model is introduced into the environmental management of nanomaterials for the first time, which provides a theoretical basis for formulating scientific and reasonable policies. The study emphasizes the importance of interdisciplinary cooperation and calls for strengthening the basic research and regulatory system of nanomaterials in order to maximize the benefits of environmental remediation and minimize the risks. This achievement lays a foundation for promoting the sustainable development of nanotechnology.
