Microplastics Interactions with PFAS and Co-transport in the Soil
AI summary Read the abstract
This chapter reviewed the interactions between microplastics and per- and polyfluoroalkyl substances (PFAS) in soil, examining how these two persistent pollutants interact and co-transport through soil profiles. Their combined presence can amplify environmental risks by facilitating PFAS mobility and bioavailability beyond what either contaminant achieves independently.
Microplastics and Per- and Polyfluoroalkyl Substances (PFAS) are two emerging environmental pollutants that have gained significant considerable interest due to their long-term existence, mobility, and possible negative effects on human health safety and the environment. Both microplastics and PFAS have been detected in different ecosystems that include soil, and their potential interactions and co-transport in soil can have significant implications for their fate and behavior. This chapter presents an overview of the interactions between microplastics and PFAS in soil, including their co-transport, sorption, and desorption. The chapter highlights the need for an improved understanding of the interactions between microplastics and PFAS in soil and developing successful and effective mitigation methods and techniques to minimize their adverse effects on environment. The results highlight the critical need for a deeper comprehension of the interactions between microplastics and PFAS, especially in soil environments. To minimize their negative environmental effects, appropriate mitigation techniques must be developed, which requires a greater understanding. In addition to highlighting the present level of study on MPs and PFAS in soil, this synopsis of the literature also stresses the necessity of taking preventative action in order to mitigate potential environmental dangers.

This review examined how PFAS and micro/nanoplastics co-occur in the environment, form interfacial adsorption complexes, and interact synergistically within organisms. The authors found that the two contaminant classes amplify each other's toxicity in co-exposure scenarios and that their shared transport pathways complicate standard risk assessment.
From co-occurrence to co-existence and co-exposure: Associations between per- and polyfluoroalkyl substances and microplastics in the environment
AI summary Read the abstract
This review examines the growing recognition that PFAS chemicals and microplastics frequently co-occur in the environment and may interact in ways that affect both ecological and human health. Researchers identified four major sources that emit both pollutants simultaneously and found strong evidence that PFAS can adsorb onto microplastic surfaces and be co-transported through the environment. The study calls for standardized methods and long-term studies to better understand the combined exposure risks of these two widespread contaminant classes.
Microplastic and nanoplastic interactions with per- and polyfluoroalkyl substances (PFAS) in soils: a critical review of main findings and knowledge gaps.
AI summary Read the abstract
Microplastics in soil (from things like compost, sewage sludge, and irrigation water) can sometimes team up with "forever chemicals" (PFAS) and carry them further into the environment, but this review of 37 studies found it's not a guaranteed effect, since it depends heavily on the type of plastic, soil conditions, and chemical properties involved. This matters because PFAS and microplastics both end up in the food we grow, but scientists still don't know exactly when or how much plastics make PFAS contamination worse, so more real-world (not just lab) testing is needed before we can say how big a risk this combo poses to our food and health
