“…PFOS was first observed in atmospheric particulate matter in two Japanese cities in 2003 by Sasaki et al [170] at concentrations ranging from nondetectable values to 21.8 pg/m 3 . PFOS was also observed in atmospheric particles above Lake Ontario by Boulanger et al [118] at concentrations up to 8.1 pg/m 3 . Berger et al [168] observed PFSAs and PFCAs in the particulate phase of air samples collected in England, at concentrations ranging from nondetectable values (PFUA and PFDoA) to 828 pg/m 3 (PFOA).…”

“…Mean indoor concentrations of NMeFOSE and NEtFOSE (1490 pg/m 3 and 740 pg/m 3 respectively) were approximately 10 to 20 times greater than mean outdoor concentrations (82 pg/m 3 and 87 pg/m 3 respectively), indicating that indoor air may in fact be a source of FSAs to the outside environment [167]. Boulanger et al [118] collected air samples above Lake Ontario and observed NEtFOSA and NEtFOSE at concentrations ranging from 0.5 to 1.1 pg/m 3 .…”

“…Across Japan, there was a tendency for PFOA to be the predominant contaminant of outdoor air, particularly in Osaka [33]. Boulanger et al [34] reported that the mean concentration of PFOS in particulate-phase air samples was 6.4 pg/m 3 (SD 3.3) in the Great Lakes. In Manchester, PFOA and PFOS were both detected at relatively high concentrations (341 and 46 pg/m 3 , respectively) [35].…”

Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) comprise a class of per- and poly-fluorinated compounds that have been detected in the environment as well as in humans. The aim of this review is to summarize several monitoring studies in Japan and characterize the toxicokinetics of these compounds. We found that the levels of contamination by these compounds had unique patterns in Japan. The levels of PFOA in serum from inhabitants of the Kansai region were higher than those of other regions. The PFOA levels in air and water samples from the Kansai region were also relatively high. The estimated intakes from these routes partly explain the differences in the serum levels. The toxicokinetics of these compounds have been investigated. Serum samples from male participants had significantly higher geometric means for PFOS and PFOA compared to samples from female participants. This sex-related difference was partly simulated by menstrual blood loss. There are large interspecies differences in the excretion pathways of these compounds. The serum clearances of PFOA via urine were 300-1,000-fold lower in humans than in Wistar rats and Japanese macaques. On the other hand, the biliary excretion of these compounds was comparable in rats and humans, and the long half-lives in humans may be attributable to the low levels of urinary excretion and high biliary reabsorption rates. These findings suggest that qualitative differences in the excretion routes exist between humans and other species. For risk assessment of these compounds, further information regarding sources of exposure and their toxicokinetics is needed.

“…Surface water polluted by industry in Germany has been shown to contain PFOS concentrations up to 4,390 ng/L (Schaefer 2006), surface water from fire drill area in Sweden contained between 200-2,200 ng/L PFOS (Swedish EPA 2004), and open Great Lake in the USA have been shown to contain PFOS concentrations between 21 and 70 ng/L (Boulanger et al 2005). Levels of perfluorooctanoic acid (PFOA) are in the same order of magnitude.…”

Sorption of perfluorinated compounds from contaminated water to activated carbon

et al. 2010

Introduction Perfluorinated compounds (PFC) are toxic and bioaccumulative compounds that are ubiquitous in the environment. It is important to develop effective techniques to remove PFC from water. This study is the first to investigate sorption of PFC to activated carbon (AC) at environmentally relevant nanogram per liter concentrations. Methods Batch AC sorption isotherms were measured for water from a contaminated groundwater well, for three perfluorosulfonates and five perfluoroacetic acids. Results For perfluorooctane sulfonate and perfluorooctanoic acid Freundlich sorption coefficients, log K iF , for powdered activated carbon (PAC) were 4.0 and 3.8 (ng/g)(ng/L) -n , respectively, and for granular activated carbon (GAC) were 2.7 and 2.3 (ng/g)(ng/L) -n , respectively. Sorption was nonlinear, with Freundlich n coefficients generally around 0.5. The K iF on both GAC and PAC were PFC chain-length dependant, with increasing number of carbon yielding increasing K iF . This chain-length dependence appeared stronger for perfluorosulfonates than for perfluoroacetic acids. Tests with short (10 min) adsorption times still yielded substantial PFC removal (20-40% for GAC, 60-90% for PAC) and revealed that AC is probably suitable for PFC removal in flow-through systems. A perfluorinated polymer, Teflon, was also tested as a PFC removal agent but proved not to be effective for PFC-contaminated water purification.
