“…However, the total concentration of PFAS in the depression soil samples was twice that of the soil at the outer edges of the other three plant areas, indicating that rainwater plays an important role in the diffusion and accumulation of regional PFAS. 26,27 Additionally, PFBA had a high concentration in the northwest puddled soil, sediment, and water samples (21.63, 57.37, 89.11%, respectively), while its concentration was low in other environmental samples (1.28 to 9.36%). This pattern is consistent with the behavior of many environmental contaminants, which are transported by water movement and eventually deposited in soil or sediment where they can concentrate.…”

Driven by the global popularity of electric vehicles and the shortage of critical raw materials for batteries, the spent lithium-ion power battery (LIPB) recycling industry has exhibited explosive growth in both quantity and scale. However, relatively little information is known about the environmental risks posed by LIPB recycling, in particular with regards to perfluoroalkyl and polyfluoroalkyl substances (PFAS). In this work, suspect screening and nontarget analysis were carried out to characterize PFAS in soil, dust, water and sediment from a LIPB recycling area. Twentyfive PFAS from nine classes were identified at confidence level 3 or above, including 13 legacy and 12 emerging PFAS, as well as two ultrashort-chain PFAS. Based on the target analysis of 16 PFAS, at least nine were detected in each environmental sample, indicating their widespread presence in a LIPB recycling area. Perfluorodecanoic acid, perfluorooctanesulfonic acid and trifluoromethanesulfonamide showed significant differences in the four phenotypic parameters (growth, movement, survival and fecundity) of Caenorhabditis elegans and were the most toxic substances in all target PFAS at an exposure concentration of 200 μM. Our project provides first-hand information on the existence and environmental risk of PFAS, facilitating the formulation of regulations and green development of the LIPB recycling industry.

“…Occurrence and migration of PFASs in the environment are influenced not only by the physicochemical properties of the chemicals but also by environmental parameters. The migration of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) in groundwater is very complex and disturbed by many factors, including the physicochemical properties (surface charge, organic matter, and minerals) and solution chemistry (ionic strength and cation type) of the aquifers medium (Lyu, Liu, Sun, et al, 2020; Mahinroosta et al, 2021). Among them, some studies have shown that the migration of fluoride in porous media is mainly influenced by electrostatic interactions, hydrogen bonding, ligand exchange, and hydrophobic interactions (Lv et al, 2018; McKenzie et al, 2015).…”

Soil and groundwater contamination has always been a global concern. Contaminants are migrated and transformed in the soil and groundwater environments, which in turn pose potential environmental risks to humans. This paper describes four typical contaminants, including heavy metals, polycyclic aromatic hydrocarbons, microplastics, and perfluorinated and polyfluoroalkyl substances. Based on a systematic summary of the sources, hazards, and migration behaviors of these four contaminants, various existing remediation methods are analyzed, and the advantages and disadvantages of different methods are discussed. Finally, the future research prospects of soil and groundwater remediation are described, and the significance of the study of contaminant migration and remediation in the subsurface environment is emphasized. This research can help to provide theoretical and technical support for the study of contaminant migration and removal in soil and groundwater environments, and further improve the removal rate in actual contaminant sites.

“…Owing to their chemical properties, PFAS are anthropogenic pollutants highly persistent and mobile in the environment, spreading worldwide due to their intense use in various industrial applications (EEA, 2023). Once released into the environment, PFAS result resistant to chemical and biological degradation, and their movement in the watershed is mainly driven by the surface and groundwater flows (Mahinroosta et al, 2021;Raschke et al, 2022).…”
