“…Perfluoroalkyl substances (PFASs) have been manufactured and used in many industrial products and manufacturing processes, such as lubricants, firefighting foams, stain-resistant treatments, and electroplating and coating additives, for more than 60 years (Giesy and Kannan 2002;Prevedouros et al 2006). As a type of emerging persistent and bioaccumulative environmental contaminants, they have received great scientific concerns due to their ubiquitous environmental distribution (Ahrens 2011;Ahrens et al 2011;Bao et al 2010;Houde et al 2011;Naile et al 2010;Young et al 2007) as well as their potential toxicity to ecological system and human (Lau et al 2004;Olsen et al 2009).…”

In the present study, we investigated concentrations and composition profiles of perfluoroalkyl substances (PFASs) in surface water from the Daling River in different seasons. The highest concentration of ΣPFASs (9540 ng L −1 ) and dominant homologues were found in surface water collected in summer. Perfluorobutanoic acid (PFBA), perfluorobutane sulfonate (PFBS), and perfluorooctanoic acid (PFOA) were the dominant PFASs in four seasons with a total contribution of over 90 %. The discharge of two fluorine chemical industry parks was predicted to be the main contamination source of PFASs in the study area. The daily and annual mass flows were calculated according to data of detected PFAS concentrations and water discharge, and the annual mass loading of PFASs into the Bohai Sea from the Daling River reached to 461 kg year −1 . Hazard assessment indicated that concentrations of PFASs in study area had little risk to aquatic organisms and wildlife. However, the multiple health risk would be relatively high if the water was served as drinking water in the study area.

“…Perfluorinated chemicals or perfluoroalkyl substances (herein referred to as PFASs) are ubiquitous pollutants detected globally in a wide range of environmental samples including aquatic and terrestrial biota, humans, air and household dust, with perfluorooctanoate (PFOA) and perfluorooctanoate sulphonate (PFOS) the most commonly detected, well-known and best studied (Giesy and Kannan, 2002;Gewurtz et al 2009;Butt et al2010; Thompson et al 2011;Zhang et al 2011). The strong carbon-fluorine bonds in these compounds make them very resistant to degradation processes (Remde and Debus, 1996;Key et al, 1998;Liou et al, 2010) and as a result, they have the potential to bioaccumulate in the food web (Giesy and Kannan, 2001;Aherns et al 2010a).…”

Perfluorooctanesulfonylfluoride (POSF)-based compounds have been manufactured and used in a variety of industrial applications. These compounds degrade to perfluorooctanesulfonate (PFOS) which is regarded as a persistent endstage metabolite and is found to accumulate in tissues of humans and wildlife. PFOS, perfluorohexanesulfonate (PFHxS), perfluorooctanoate (PFOA), and perfluorooctanesulfonamide (PFOSA) have been found in human sera from the United States. In this study, concentrations of PFHxS, perfluorobutanesulfonate (PFBS), PFOS, perfluorohexanoic acid (PFHxA), PFOA, perfluorononanoic acid (PFNA), perfluorodecanoic acid (PFDA), perfluoroundecanoic acid (PFUnDA), perfluorododecanoic acid (PFDoDA), and PFOSA were measured in 85 samples of whole human blood collected from nine cities (eight provinces) in China, including Shenyang (Liaoning), Beijing (Hebei), Zhengzhou (Henan), Jintan (Jiangsu), Wuhan (Hubei), Zhoushan (Zhejiang), Guiyang (Guizhou), Xiamen (Fujian), and Fuzhou (Fujian). Among the 10 perfluorinated compounds (PFCs) measured, PFOS was the predominant compound. The mean concentration of PFOS was greatest in samples collected from Shenyang (79.2 ng/mL) and least in samples from Jintan (3.72 ng/mL). PFHxS was the next most abundant perfluorochemical in the samples. No age-related differences in the concentrations of PFOA, PFOS, PFOSA, and PFHxS were observed. Gender-related differences were found, with males higher for PFOS and PFHxS, and females higher in PFUnDA. Concentrations of PFHxS were positively correlated with those of PFOS, while concentrations of PFNA, PFDA, and PFUnDA were positively correlated with those of PFOA. There were differences in the concentration profiles (percentage composition) of various PFCs in the samples among the nine cities.
