Abstract
Nanotechnology has emerged as a transformative tool in environmental remediation, offering innovative solutions to address pollution and restore ecosystems. This review explores the opportunities presented by nanomaterials, including their enhanced reactivity, selectivity, and efficiency in applications such as water purification, soil decontamination, and air pollution control. Key advancements in nanotechnology-driven approaches, such as the use of nanoparticles, nanocomposites, and nanostructured membranes, are highlighted for their potential to revolutionize traditional remediation techniques. However, the rapid development and deployment of nanotechnologies also raise significant concerns regarding their environmental and human health risks. Issues such as nanoparticle toxicity, bioaccumulation, and long-term ecological impacts remain critical challenges that demand thorough investigation and regulation. By examining both the benefits and risks, this paper aims to provide a balanced perspective on the role of nanotechnology in environmental remediation, emphasizing the need for sustainable practices and responsible innovation to maximize its potential while minimizing unintended consequences.
