“…However, other factors, mainly dust ingestion, also contribute to overall exposure and account for a fraction that may be highly variable; they range from a few percentage units to approximately 40% in the worst case (Björklund et al, 2009). We hypothesize that the generally limited use of carpets in Italy might play a role, as suggested by some studies that showed a positive correlation between the percentage of home carpeting and PFAS internal dose (Kubwabo et al, 2005;Gewurtz et al, 2009), which was also confirmed by studies carried out in other Mediterranean countries (Ericson Jogsten et al, 2012), which, like Italy, have limited or no use of fitted carpets.…”

Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) concentrations were determined in serum samples collected in 2011-2012 from 549 nulliparous Italian women of reproductive age who resided in six different Italian Regions. Assessment of exposure to perfluorinated compounds was part of a large human biomonitoring study (Project Life Plus "Womenbiopop") that aimed at examining the exposure of women of reproductive age to priority organic pollutants. The median concentrations of PFOS and PFOA were 2.43, and 1.55 ng g(-1), respectively. Significant differences in the concentrations of both compounds were observed among the six Regions. Women from central Italy had the highest levels of both compounds, followed by women from northern Italy, and southern Italy. No differences in the PFOS concentrations were found between women from urban/industrial areas and women from rural areas, whereas the levels of PFOA were significantly higher in women residing in urban/industrial areas than in women residing in rural areas. Taken together, the observed concentrations confirm that the overall exposure of the Italian population is among the lowest observed in industrialized countries. A downward temporal trend in exposure was observed for both compounds when comparing the results from the present study with those assessed in a study conducted in 2008.

“…Moreover, recent studies have reported concentrations of PFOS and other PFAS in indoor air (principally vapour phase, but with some particulate phase compounds incorporated) (Ericson Jogsten et al, 2012;Goosey and Harrad, 2012;Shoeib et al, 2011). In these, PFOS was the most prevalent PFAS, with a wide range of concentrations between countries (for example, lower values detected in Spain, higher in the UK).…”

Perfluorooctane sulfonate (PFOS) found extensive use for over 60 years up until its restriction in the early 2000s, culminating in its listing under the Stockholm Convention on Persistent Organic Pollutants (POPs) in 2009. Efforts to minimise human body burdens are hindered by uncertainty over their precise origins. While diet appears the principal source for the majority of western populations (with other pathways like dust ingestion, drinking water and inhalation also important contributors); the role played by exposure to PFOS-precursor compounds followed by in vivo metabolism to PFOS as the ultimate highly stable end-product is unclear. Such PFOS-precursor compounds include perfluorooctane sulfonamide derivates, e.g., perfluorooctane sulfonamides (FOSAs) and sulfonamidoethanols (FOSEs). Understanding the indirect contribution of such precursors to human body burdens of PFOS is important as a significant contribution from this pathway would render the margin of safety between the current exposure limits and estimates of external exposure to PFOS alone, narrower than hitherto appreciated. Estimates derived from mathematical modelling studies, put the contribution of so-called "precursor exposure" at between 10% and 40% of total PFOS body burdens. However, there are substantial uncertainties associated with such approaches. This paper reviews current understanding of human exposure to PFOS, with particular reference to recent research highlighting the potential of environmental forensics approaches based on the relative abundance and chiral signatures of branched chain PFOS isomers to provide definitive insights into the role played by "precursor exposure".

“…The intake of ionic PFASs via house dust in Catalonia, Spain, was estimated to be lower ranging from 0.05 and 0.3 ng/(d·kg). 86 Fu et al calculated a daily intake of ionic PFASs via dust of 1680 ng/(d·kg) and 1.0 ng/(d·kg) for workers of a fluorochemical plant and ordinary residents, respectively. 71 The exposure of those workers was 3 orders of magnitude higher than of workers from the textile manufacturing plant.…”

ABSTRACT:The manufacturing of high-performance fabrics requires numerous chemical treatment steps that involve the use of per-and polyfluoroalkyl substances (PFASs) to protect apparel against water, stain, and oil penetration. However, air and wastewater emissions of PFASs generated during this manufacturing are a potential threat to both factory workers and the environment. We investigated the occurrence and distribution of PFASs in wastewater, air, airborne particles, and settled dust in a textile manufacturing plant in China. PFOA and PFDA or their precursor compounds 8:2 FTOH and 10:2 FTOH were the dominant compounds in all environmental media tested, revealing that long-chain PFASs were preferably used for the manufacturing of functional garments. Besides, PFASs were detected along the textile manufacturing chain, indicating that they were used as durable water repellents and as surfactants in, for example, coating agents. The workers' exposure to FTOHs via air inhalation was up to 5 orders of magnitude higher than the background exposure of the general western population. To the best of our knowledge, this is the first study providing information regarding the emission of PFASs during the manufacturing of textiles via various environmental media.
