TLDR
The knowledge gap caused by the lack of direct detection of precursor chemicals in environmental samples can be bridged by laboratory investigations of important precursors such as fluorotelomer-based compounds and perfluoroalkane sulfonamido derivatives, and research directions with regard to future biodegradation studies, environmental monitoring and ecotoxicological assessment are suggested.About:

Global emission inventories for C4-C14 perfluoroalkyl carboxylic acid (PFCA) homologues from 1951 to 2030, Part I: production and emissions from quantifiable sources.
TL;DR: This work quantifies global emissions of C4-C14 perfluoroalkyl carboxylic acid (PFCA) homologues during the life-cycle of products based on perfluorooctanoic Acid (PFOA), perfLUorononanoic acid (PFNA), perfluarooctane sulfonyl fluoride (POSF), and fluorotelomer compounds, and addresses the uncertainties of the PFCA emissions by defining a lower
Journal ArticleDOI
Perfluoroalkyl and polyfluoroalkyl substances in consumer products
TL;DR: This study proves the importance of screening and monitoring of consumer products for PFAS loads and the necessity for an action to regulate the use of PFASs, especially PFOA, in consumer products.
Journal Article
Perfluorochemicals: potential sources of and migration from food packaging Part A Chemistry, analysis, control, exposure & risk assessment
TL;DR: Data will be presented on the types of perfluoro chemicals that are used in food packaging and cookware and the migration or potential for migration of these chemicals into foods or food simulating liquids.
Journal ArticleDOI
Novel treatment technologies for PFAS compounds: A critical review.
TL;DR: A baseline for understanding research needs to better develop treatment technologies for PFOA and PFOS in groundwater is provided and the development and demonstration of promising in situ treatment technologies at the pilot and full scale are demonstrated.
Journal ArticleDOI
A review of emerging technologies for remediation of PFASs
Ian L. Ross,Jeffrey T. McDonough,Jonathan Miles,Peter Storch,Parvathy Thelakkat Kochunarayanan,Erica Kalve,Jake Hurst,Soumitri S. Dasgupta,Jeff Burdick +8 more
TL;DR: The need for remediation of polyand perfluoroalkyl substances (PFASs) is growing as a result of more regulatory attention to this new class of contaminants with diminishing water quality standards being promulgated, commonly in the parts per trillion range.

Polycyclic Aromatic Hydrocarbon Biodegradation as a Function of Oxygen Tension in Contaminated Soil
TL;DR: In this paper, the effect of soil gas oxygen concentration on the degradation and mineralization of spiked 14C-pyrene and nonspiked 16 priority pollutant polycyclic aromatic hydrocarbons (PAH) present in the soil was evaluated.
Journal ArticleDOI
Enantiospecific perfluorooctane sulfonate (PFOS) analysis reveals evidence for the source contribution of PFOS-precursors to the Lake Ontario foodweb.
Brian J. Asher,Yuan Wang,Amila O. De Silva,Sean Backus,Derek C. G. Muir,Charles S. Wong,Charles S. Wong,Jonathan W. Martin +7 more
TL;DR: Empirical observations with a new analytical tool confirm previous suggestions that PFOS-precursors contribute to PFOS in the food web, likely via sediment and suggest that future PFOS exposures in this ecosystem will be influenced by an in situ source, and that the apparent environmental behavior of PFOS can be confounded by precursors.

Presence and Partitioning Behavior of Polyfluorinated Iodine Alkanes in Environmental Matrices around a Fluorochemical Manufacturing Plant: Another Possible Source for Perfluorinated Carboxylic Acids?
Ting Ruan,Yawei Wang,Thanh Wang,Qinghua Zhang,Lei Ding,Jiyan Liu,Chang Wang,Guangbo Qu,Guibin Jiang +8 more
TL;DR: The identification of these PFIs indicates that unintentional release during the telomer reaction process might also be another route for the formation and distribution of certain polyfluorinated alcohols, aldehydes, and carboxylic acid derivatives under oxidative conditions in the environment.

Polyfluorinated telomers in precipitation and surface water in an urban area of Japan
TL;DR: The results of this study indicate that FTOHs released into the air contaminate rain and that those released from water disposal sites contaminate surface water.

Aerobic soil biodegradation of 8:2 fluorotelomer stearate monoester.
TL;DR: Analysis of mass spectrometry fragmentation patterns and chromatography supported the conclusion that hydrolysis of the ester linkage is predominantly the first step in the degradation of 8:2 FTS with the ultimate formation of terminal products such as PFOA.
