摘要

全氟辛酸(PFOA)土壤污染是一个全球关注的问题。土壤中的PFOA可以进入植物体内，影响植物生长，威胁食品安全。因此，了解PFOA的植物利用和植物毒性有利于评估PFOA污染土壤的环境风险。本文从PFOA对陆生植物的吸收、运输、分布、植物毒性及其作用机制等方面综述了近年来有关研究进展。根据目前的研究，PFOA主要通过植物根系吸收，并通过影响植物的抗氧化系统和代谢过程对植物产生不良影响。对田间或高等陆生植物的研究仍然很少。鉴于探索PFOA潜在的修复方法的重要性，需要开展更多综合考虑土壤和环境因素的研究，以了解其对植物利用和毒性作用的具体机制。

Interaction of Perfluorooctanoic Acid with terrestrial plants: Uptake, transfer and phytotoxicity aspects

ABSTRACT Soil contamination with perfluorooctanoic acid (PFOA) is a global concern. PFOA in soil can enter plants, affect plant growth and threaten food safety. Therefore, understanding the plant utilization and phytotoxicity of PFOA is conducive to assessing the environmental risk of soil contaminated with PFOA. This review analyzed recent studies about the uptake and effects of PFOA on terrestrial plants from the aspects of absorption, transport, distribution, phytotoxicity, and the underlying mechanism. Based on current research, PFOA was predominantly taken by plant roots and showed adverse effects on plants by affecting the antioxidant system and metabolic process. Research in field or higher terrestrial plants is still very scarce. Given the importance of exploring the potential remediation methods for PFOA, more research with comprehensive consideration of soil and environmental factors should be carried out to tell its specific mechanisms of plant utilization and toxicity action.

期刊介绍： Environmental Pollutants & Bioavailability is a peer-reviewed open access forum for insights on the chemical aspects of pollutants in the environment and biota, and their impacts on the uptake of the substances by living organisms. Topics include the occurrence, distribution, transport, transformation, transfer, fate, and effects of environmental pollutants, as well as their impact on living organisms. Substances of interests include heavy metals, persistent organic pollutants, and emerging contaminants, such as engineered nanomaterials, as well as pharmaceuticals and personal-care products as pollutants.
