“…This result recon rms that the organic content is the determinant factor of adsorption a nity and hydrophobic interaction between the carbon chain and the organic matters is the driving force for the sorption of PFCs on sediment. This result is similar to published studies that show the content of TOC is the dominant parameter affecting the adsorption of PFOS and PFOA on sediment (Gobas et al 2003, Christopher P. Higgins et al 2006, Zareitalabad et al 2013, Du et al 2014, Cao et al 2015. However, the biological activity of sludge was observed to be able to affect the PFC sorption, in which the sludges with high biological activity are higher sorption capacity than those with low biological activity.…”

Perfluorooctane sulfonate (PFOS) and Perfluorooctanoic acid (PFOA) are recognized as emerging environmental pollutants because of their high persistence in various environmental matrices and toxic effects on humans and animals. In Vietnam, PFOA and PFOS have been detected in surface water and sediment in recent studies. The objectives of this study were to evaluate the occurrence of PFOS and PFOA in the sediment of the Cau river, Thai Nguyen city to determine the partition coefficient between water and sediment, and to elucidate the environmental factors affecting the sorption of PFOS and PFOA to sediment. The concentration of PFOS and PFOA in surface sediment ranged from 1.19 ng/g to 4.73 ng/g and 0.17 ng/g to 1.78 ng/g, respectively, with the highest concentrations, are recorded in the areas that receiving wastewater from domestic and industrial activities. Depending on the depth, the total concentrations of PFOS and PFOA ranged from 8.41 to 19.25 ng/g and tended to decrease with increasing sediment depth. The concentrations in the surface sediments are lower than the second layer, indicating a downward trend in the use and consumption of these compounds in recent years. The water-sediment distribution coefficient (Kd) is relatively different for PFOS and PFOA, with log Kd values ranged from 1.31–1.86 and 0.08–1.31 for PFOS and PFOA, respectively. This study also confirms that the total organic carbon content is the physiochemical property that significantly affected the adsorption to sediments of PFOS and PFOA. No apparent relation was found between PFOS, PFOA concentration in sediment and clay content nor sediment particle size.

“…Comparison with literature showed that the observed PFASs concentration at the Baiyangdian Lake was much higher than the ΣPFASs of the Songhua River (0.143-1.41 ng/g), the Peal River estuary (nd-2.41 ng/g), the Nansi Lake (0.47-1.81 ng/g), and the Daliao River (0.13-0.49 ng/g) [39][40][41][42] . In whole worldwide, the ΣPFASs in sediment varied greatly.…”

This work examined the contamination of poly-and perfluorinated compounds (PFASs) in the water and sediment of the Baiyangdian Lake. The total concentration of PFASs in the surface water varied from 140.5 to 1828.5 ng/L, and the highest concentration of PFASs were observed near the entrance of Fuhe river. The topmost contaminant was sodium perfluorohexanesulfonate (PFHxS) and perfluorooctanoic acid (PFOA) in the north and south of the Baiyangdian Lake respectively, which indicated different contamination sources. The total concentration of PFASs in the sediment varied from 0.48 to 30 ng/g, and the distribution of PFASs in the sediment was similar with that in the surface water. The concentrations of polyfluoroalkyl phosphoric diesters (diPAPs) were three to four orders of magnitude lower than those of perfluorocarboxylates (PFCAs) and PFSAs. Although the pore water and the surface water had similar ΣPFASs, the concentration of perfluorodecanoic acid (PFDA) in pore water was 1.4 to 4.4 times higher than that in surface water, and the concentration of perfluoropentanoic acid (PFPeA) in pore water was 20-70% that in surface water. The results of ecological risk assessment showed that the PFASs were currently of no immediate risk to the aquatic life.Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are anthropogenic chemicals that are both oleophobic and hydrophobic. Their excellent surface activity and repellence to water, oil, and stain made them suitable for extensive applications in fire-

“…The studies about PFAAs in lake systems are relatively limited compared with those on rivers, and the majority of them are focused on several main lakes, such as the Great Lakes (Boulanger et al 2004, De Silva et al 2011, Lake Victoria in Kenya (Orata et al 2009), Tokyo Bay (Taniyasu et al 2003), Taihu Lake (Qiu, Jing, and Shi 2010, Yang, Zhu, and Liu 2011, Yu et al 2013, Guo et al 2015, Lake Chaohu (Gong et al 2015), Tangxun Lake (Zhou et al 2013), Nansi Lake in Shandong (Cao et al 2015), and Dianchi Lake in Yunnan (Zhang et al 2012).…”

“…Subsequent research has been carried out by studying several major rivers flowing through industrial factories, such as the part of Huangpu River and Pearl River located in Guangzhou (Bao et al 2010), the Yangtze River (Pan and You 2010), and multiple rivers in Laizhou Bay (Zhao et al 2013). The research on lake sediments has occurred only recently in China, focusing on Taihu Lake Liu 2011, Chen et al 2015), Dianchi Lake (Zhang et al 2012), Tangxun Lake in Hubei (Zhou et al 2013), and Nansi Lake in Shangdong (Cao et al 2015). The short carbon chain PFCAs were still dominant in the sediments, while the relative content of PFOS and long carbon chain PFCAs, such as PFUnDA, were increased.…”

Perfluoroalkyl acids (PFAAs) are emerging persistent organic pollutants that are globally distributed in the environment. In the present review, the occurrence of PFAAs and their behavior in aquatic ecosystem were summarized, and the health and ecological risk assessment and the multimedia fate simulation were investigated. PFAAs are most likely to exist in the aqueous phase, and PFAAs in atmosphere are also able to enter water bodies through diffusion and wet and dry deposition and eventually become widely distributed in various environmental media. The air-solid partition is considered to be one of the major factors in the long-distance transportation of the pollutants. The pKa values and organic carbon fraction of the sediment could influence the partition of PFAAs between water and sediment. Otherwise, PFAAs have teratogenic, mutagenic and other toxic effects and they could be accumulated by biota, and magnified through trophic level. The ecological and health risks of PFOA and PFOS were assessment. In order to explore the partition mechanism and reduce the uncertainty of the simulation of the transport, transformation and fate, the experimental methods on physicochemical properties of PFAAs should be developed. Moreover, further studies on toxicities of PFAAs are necessary for health and ecological risk assessment.
