Study on interaction, feedback, and response between perfluorinated compounds and soil environments

Abstract

The soil environment plays a crucial role in agricultural production, safeguarding water resources, and maintaining ecological balance. Additionally, the soil environment can regulate climate through carbon cycling and serves as an essential habitat for the survival of animals and humans. Therefore, a green and healthy soil environment forms the bedrock of sustainable development of biological systems and serves as the basic support for socio-economic progress, thereby affecting the survival of every organism. However, with the advancement of human society and technology, numerous emerging pollutants have gradually been identified. Among these pollutants, perfluorinated compounds (PFASs) are known for their high thermal stability, bioaccumulation potential, and strong biological toxicity. PFASs are complex persistent pollutants that infiltrate soil ecosystems through industrial emissions, agricultural practices, and household waste, posing a significant threat to soil environments as well as human health and receiving considerable attention. However, current research mainly focuses on PFASs pollution in water media, with few reports on its interaction with soil environments. Moreover, due to the diversity and heterogeneity of soil environmental factors, the species diversity of PFASs may affect the different responses between different PFASs (short and long chain types) and soil factors. Elucidating these complex relationships is crucial for developing future treatment technologies to remediate PFASs pollution. Therefore, this paper reviews the impacts of PFASs pollution on soil properties and preliminarily compares the response and effect of various environmental factors, such as pH, organic matter, and microbial communities, to PFASs stress. Furthermore, the paper provides a scientific basis and theoretical insights into the processes, transformation mechanisms, and remediation methods related to soil PFASs pollution.
