Industrial Applications, Environmental Fate, Human Exposure, and Health Effects of PFAS
AI summary Read the abstract
This research investigated how tire wear particles affect freshwater invertebrate communities, documenting toxicity of common tire rubber chemicals leached from plastic particles. The study identifies tire-derived chemicals, particularly 6-PPD-quinone, as highly toxic to aquatic invertebrates, connecting road runoff to aquatic biodiversity loss.
Poly- and perfluoroalkyl substances (PFASs) are persistent environmental pollutants widely used in industrial applications due to their thermal stability and chemical resistance. However, their persistence in the environment and potential health risks, including developmental and immunological issues, have raised significant concerns. This review highlights the industrial uses, environmental fate, and bioaccumulation of PFASs, emphasizing their widespread presence in air, water, soil, and biota. Major sources of PFAS contamination include industrial discharges, wastewater treatment, and military sites. The atmospheric transport of PFASs contributes to their deposition in remote ecosystems, while aquatic and soil contamination stems from both point and nonpoint sources. Bioaccumulation studies reveal that PFASs accumulate in organisms, leading to potential human exposure through food, water, and consumer products. This review calls for further research to address knowledge gaps in PFAS detection, behavior, and health impacts, while advocating for improved regulations to limit their release and exposure.

Per and Polyfluoroalkyl Substances (PFAS) in the Environment: Uptake, Bioaccumulation and Impact on Plants, Animals and Human Health
AI summary Read the abstract
A comprehensive review documents that PFAS compounds have been detected in virtually every environmental compartment and human matrix, causing reproductive toxicity, endocrine disruption, metabolic disruption, and immune effects across aquatic organisms, terrestrial animals, and humans. PFAS and microplastics share key exposure pathways and are frequently co-contaminants, as plastic surfaces sorb and transport PFAS into food chains and human bodies.
Per and Polyfluoroalkyl Substances (PFAS) in the Environment: Uptake, Bioaccumulation and Impact on Plants, Animals and Human Health

Forever Chemicals, Per-and Polyfluoroalkyl Substances (PFAS), in Lubrication
AI summary Read the abstract
This review examines how PFAS (per- and polyfluoroalkyl substances), known as forever chemicals, are used in lubricants and greases across automotive and industrial applications, and how they enter the environment through these products. PFAS exposure is a growing health concern because these chemicals accumulate in the body and have been linked to immune system problems, cancer, and developmental issues in humans.
