Removal of Perfluorooctane Sulfonate (PFOS) and Related Compounds From Industrial Effluents
Perfluorooctane sulfonate (PFOS) and related perfluoroalkyl surfactants (PFAS) are ubiquitous contaminants of increasing public concern due to their environmental persistence, toxicity, and bioaccumulation. These perfluorinated compounds have been used for more than half a century in a wide variety …

Perfluorooctanoic Acid (PFOA) and Perfluorooctane Sulfonate (PFOS) in an Aquatic Ecosystem - Distribution and Fate
Perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS) belong to the family of perfluorinated surfactants (PFSs). They are widely distributed and persistent in the environment. For over 50 years, they have been used in numerous applications including paper and textile treatment, production …

IMPROVING CANNABIS SATIVA'S PHYTOREMEDIATION CAPABILITIES OF FOREVER CHEMICALS THROUGH MICROBIAL INOCULATIONS
… could influence the uptake and distribution of perfluorooctane sulfonate (PFOS) in hydroponically grown hemp (Cannabis sativa L.). Plant height and stem diameter growth rates and biomass accumulation were compared across treatments with and without PFOS exposure and microbial inoculation. PFOS …

Towards understanding the fate of perfluoroalkyl compounds (PFCs) within urban environments: implications for human exposure.
Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) have been detected across the globe in a variety of media. The toxicity of these compounds and other precursors has led to concern about human exposure. The purpose of this thesis is to investigate the presence of perfluoroalkyl …

Navigating the Unregulated: A Multi-Tiered Public Health Risk Assessment of PFAS and N-DBPs Utilizing Unregulated Contaminant Monitoring Rule Data
… PFAS (e.g., Perfluorooctanoic acid (PFOA), Perfluorooctane sulfonate (PFOS), and Perfluorodecanoic acid (PFDA)) contribute to non-carcinogenic risk, the short-chain Perfluorohexane sulfonic acid (PFHxS) exhibited a Hazard Quotient (HQ) that exceeded the safety threshold by over two orders of …

Fish Consumption Based PFAS Risk Assessment for Recreational Anglers in Chicago, IL & Benton Harbor, MI
… values from the State of Michigan paired with a Perfluorooctane Sulfonate (PFOS) RfD from Pachkowski et al. (US EPA, 2011; ATSDR, 2003). Fish consumption survey data was compiled to assess consumption patterns, and IBM SPSS Modeler was used to perform an Asymmetric Two-sided Chi-Square test with …

Fate and remediation of emerging organic contaminants in aquatic and soil environments
… most resins loaded with long-chain PFASs (e.g., perfluorooctane sulfonate (PFOS)), including polystyrene- and polyacrylic-based AER, will require a combination of salt brine and co-solvent to desorb the PFOS and regenerate the AERs. This is consistent with the importance of both electrostatic and …

Development of a Novel Perfluoroalkyl Substance Sequestration Scheme Using Alginate Macrobeads and Common Water Treatment Polymers
… a sorption enhancer for the PFASs perfluoroctanesulfonate (PFOS), perfluorooctanoate (PFOA), and perfluorononanoate (PFNA) and to elucidate potential removal mechanisms. In all cases, sorption of compounds increased beyond what can be explained by hydrophobic partitioning indicating the presence …

Rh-Based Catalysis Chemistry of Aqueous-Phase Nitrogen Treatment Reactions
… (MOF) materials for the adsorptive treatment of perfluorooctane sulfonate (PFOS) contaminated water. In this work, the sorption properties of UiO-66 metal-organic frameworks (MOFs) with varying defect were studied for the removal of PFOS. Large pore defects (~16 and ~20 Å) within the framework …
