摘要

近年来,微塑料受到广泛关注。然而,大多数关于微塑料的研究仅限于水生环境。在这篇综述中,我们对微塑料的降解途径和去除方法进行了分类和描述,包括热解、水解、生物降解和高级氧化技术(如超声波机械降解)。此外,我们还重点介绍了光催化降解作为一种原位去除土壤中微塑料技术的适用性,为今后的研究提供参考。虽然土壤是微塑料的重要吸收汇,其丰度也远高于海洋,但现有研究对土壤中微塑料的环境降解和去除机制缺乏全面总结。在本综述中,我们对去除和降解方法进行了分类和描述,包括热解、水解、生物降解和高级氧化技术(如超声波机械降解)。此外,我们还重点介绍了光催化降解作为一种原位去除土壤中微塑料的技术的适用性,为今后的研究提供参考。

Review of Soil Microplastic Degradation Pathways and Remediation Techniques

Review of Soil Microplastic Degradation Pathways and Remediation Techniques

Microplastics have received widespread attention in recent years. However, most studies on microplastics have been limited to the aquatic environment. In this review, we categorize and describe the microplastic's degradation pathways and removal methods, including pyrolysis, hydrolysis, biodegradation, and advanced oxidation techniques, such as ultrasonic mechanical degradation. Additionally, we focus on the applicability of photocatalytic degradation as an in-situ removal technique for microplastics in soil, providing a reference for future research. Although soil is an important sink for microplastics and has a much higher abundance than the oceans, there is a lack of comprehensive summary regarding the mechanisms of environmental degradation and removal of microplastics in soil in existing research. In this review, we categorize and describe removal and degradation methods, including pyrolysis, hydrolysis, biodegradation, and advanced oxidation techniques, such as ultrasonic mechanical degradation. Additionally, we focus on the applicability of photocatalytic degradation as an in-situ removal technique for microplastics in soil, providing a reference for future research.

期刊介绍: International Journal of Environmental Research is a multidisciplinary journal concerned with all aspects of environment. In pursuit of these, environmentalist disciplines are invited to contribute their knowledge and experience. International Journal of Environmental Research publishes original research papers, research notes and reviews across the broad field of environment. These include but are not limited to environmental science, environmental engineering, environmental management and planning and environmental design, urban and regional landscape design and natural disaster management. Thus high quality research papers or reviews dealing with any aspect of environment are welcomed. Papers may be theoretical, interpretative or experimental.
