8-2 Fluorotelomer alcohol aerobic soil biodegradation: Pathways, metabolites, and metabolite yields

Perfluoroalkyl acids (PFAAs) in riverine and coastal sediments of Laizhou Bay, North China

“…The solid lines with arrows indicate the marine currents directions in Laizhou Bay (Qiao et al, 2010). The circles with arrows indicate the current circulations near the Laizhou Shoal (Wang et al, 2009).…”

“…1). The clockwise tidal residual current circle caused by the tide and influenced by the geographic conditions captures sediments and builds up the shoal (Wang et al, 2009). Hence, PFAAs detected at A5 and B5 might be transported to the Laizhou Shoal.…”

Effects of fluorotelomer alcohol 8:2 FTOH on steroidogenesis in H295R cells: Targeting the cAMP signalling cascade

“…Recently, these chemicals were found to have a wide distribution in the ambient atmosphere (Jahnke et al, 2007;Stock et al, 2004), including in indoor air and dust (Shoeib et al, 2006;Strynar and Lindstrom, 2008). Previous studies have found that FTOHs Toxicology and Applied Pharmacology 247 (2010) [222][223][224][225][226][227][228] can be biotransformed to perfluorinated acids (Wang et al, , 2009. Specifically, in both rat and mouse hepatocytes, 1H, 1H, 2H, 2H-perfluoro-decan-1-ol (8:2 FTOH) is metabolized to PFOA and PFNA (Henderson and Smith, 2007;Martin et al, 2005), both of which have been reported to occur in human and wildlife.…”

Aerobic Soil Biotransformation of 6:2 Fluorotelomer Iodide

“…Chemical names, acronyms, and molecular structures of the poly-and perfluoroalkyl substances described in this paper are shown in Experimental System. The Sassafras soil (Ultisol) used to study 6:2 and 8:2 FTOH aerobic biotransformation 19,34,35 was also selected as the microcosm to study 6:2 FTI aerobic biodegradation. The soil was collected from the same site in an undisturbed forested area for more than 40 years in Newark, DE in March, 2012, was sieved immediately upon collection via a 2 mm sieve, and was stored at 4°C until use.…”
