“…The levels of PFOS and PFOA in the Yangtze and Pearl Rivers (So et al, 2007) were of the same order of magnitude with those measured in the Po River, Italy (2e12 ng/L and 2e237 ng/L) (Loos et al, 2008), the Ruhr River (5.0 and 48.0 ng/L) in Germany (Skutlarek et al, 2006) and the Cape Fear River basin (28.9 and 12.6 ng/L) in North Carolina, USA (Nakayama et al, 2007).…”

“…In recent studies, PFOA has been found to be the predominant PFAA in North Bohai coastal rivers (Wang et al, 2011b), rivers in Tianjin (Pan et al, 2011), Dianchi Lake , Hanjiang River , the Huaihe River Basin and Taihu Lake in China ; Water samples from Hanoi city and its surrounding areas in Vietnam (Kim et al, 2013); Yodo River basin in Japan (Lien et al, 2008); the watershed of River Po in Northern Italy (Loos et al, 2008); and Mediterranean coastal rivers in Spain (Sánchez-Avila et al, 2010). However, only water in the Yodo and Po Rivers contained concentrations of PFOA that exceeded 1000 ng/L, which was comparable to this study (Table S7).…”

a b s t r a c tPerfluoroalkyl acids (PFAAs) are emerging contaminants that have raised great concern in recent years. While PFAAs manufacturing becomes regulated in developed countries, production has been partly shifted to China. Eight fluoropolymer manufacturing facilities located in the South Bohai coastal region, one of the most populated areas of China, have been used to manufacture PFAA-related substances since 2001. The environmental consequence of the intensive production of PFAAs in this region remains largely unknown. We analyzed 17 PFAAs in twelve coastal rivers of this region, and found staggeringly high concentrations of perfluorooctanoic acid (PFOA) ranging from 0.96 to 4534.41 ng/L. The highest concentration was observed in the Xiaoqing River which received effluents from certain fluoropolymer facilities. Principal component analysis indicated similar sources of several perfluoroalkyl carboxylic acids (PFCAs) in all rivers, which indicated that atmospheric transport, wastewater treatment and surface runoff also acted as important supplements to direct discharge to surface water.

Perfluorooctane sulphonate (PFOS) and perfluorooctanoic acid (PFOA) are chemicals that have been used for many years as surfactants in a variety of industrial and consumer products. Owing to their persistent, bioaccumulative and toxic (PBT) characteristics, PFOS has been phased out by its principal producer and the use of PFOA has been reduced. This PBT potential and a number of pollution incidents have led in recent years to an increase in studies surveying the concentrations of PFOS and PFOA in environmental waters worldwide. This paper reviews the results of these studies, as well as the monitoring that was conducted after the pollution incidents. The results of surveys suggest that PFOS and PFOA are found in environmental waters worldwide at low levels. In general, these levels are below health-based values set by international authoritative bodies for drinking water. There have been limited measurements of these chemicals in drinking water, but again these are below health-based values, except in some cases following pollution incidents. Monitoring studies suggested that where PFOS and PFOA were detected, they were at similar levels in both source and drinking water, suggesting that drinking water treatment does not remove these chemicals. However, new data show that PFOS and PFOA are effectively removed by granular activated carbon absorbers in practice. Further research is required on the newer perfluorinated chemicals that appear to be safer, but their degradation products have not as yet been fully studied.
