Isomeric specific partitioning behaviors of perfluoroalkyl substances in water dissolved phase, suspended particulate matters and sediments in Liao River Basin and Taihu Lake, China

Occurrence and distribution of perfluoroalkyl substances (PFASs) in surface water and bottom water of the Shuangtaizi Estuary, China

“…Short-chain PFCAs, such as PFBA, PFPeA and PFHxA, were not measured in that study. In 2012, P PFASs was measured to be in the range of 44.4e781 ng L À1 with PFBS as the predominant homologue (mean 134 ng L À1 ), followed by PFOA (mean 12.0 ng L À1 ) (Chen et al, 2015). In the latter study, PFBA was not analyzed.…”

“…Therefore, the PFASs pollution at sites S4 and S5 was higher than that at S6 and S7. The relatively high PFASs pollution at S12 and S13 might be caused by the input of PFASs pollution from the Daliao River (Chen et al, 2015;Sun et al, 2011;Yang et al, 2011).…”

“…Industrial and municipal activities at the upstream of the Shuangtaizi River caused the contamination of PFASs (Chen et al, 2015). In addition, the contamination of PFASs in the Daling River might have certain impact, as there are several diversion canals connecting the downstream of the Daling River and the Shuangtaizi River around the site R4, which could transport PFASs via the aqueous phase.…”

“…It is reported that the Daling River and the Daliao River were highly polluted by PFASs from industrial and domestic sources (Chen et al, 2015;Meng et al, 2015;Sun et al, 2011;Wang et al, 2015;Yang et al, 2011). Thus, the Shuangtaizi Estuary should also have the contamination of PFASs, which might threaten the wetlands' ecosystem.…”

Levels and distributions of polybrominated diphenyl ethers, hexabromocyclododecane, and tetrabromobisphenol A in sediments from Taihu Lake, China

“…For example, Taihu Lake has suffered from serious eutrophication due to nitrogen and phosphorus overloading. Recently, some contaminants such as perfluoroalkyl substances and chlorinated dioxins and organic phosphate flame retardants have been detected in this region (Chen et al 2015;Cao et al 2012;Zhou et al 2012a, b). However, little information is available regarding the level and distribution of BFRs in environmental matrices in this region (Zhou et al 2012a, b).…”
