Perfluorinated Compounds in Aquatic Products from Bohai Bay, Tianjin, China

A review of sources, multimedia distribution and health risks of perfluoroalkyl acids (PFAAs) in China

“…Levels of PFAAs in various foodstuffs were analyzed, including poultry, livestock and seafood (Wang et al, 2010a;Lu et al, 2011;Chen et al, 2011c;Zhang et al, 2010a). Mean concentrations of PFOS and PFOA in foodstuffs collected from 17 cities of 15 provinces in China were 0.05-1.99 and 0.06-12.5 ng g À1 fresh weight (fwt), respectively (Zhang et al, 2010a).…”

Are levels of perfluoroalkyl substances in soil related to urbanization in rapidly developing coastal areas in North China?

“…Since 2008, we have been conducting systematic research of organochlorine pesticides (OCPs), polycyclic aromatic hydrocarbons (PAHs) and heavy metals in environmental matrices along the Bohai Sea. It was found that industrialization and urbanization were strongly related to their pollution and distribution Chen et al, 2011;Wang et al, 2011a). The Yellow River, Haihe River and Liaohe River systems are the most important water sources in this region, and most of the river systems eventually flow into the Bohai and Yellow Seas.…”

“…PFASs in water were also reported Luo et al, 2010;Chen et al, 2011;Wang et al, 2011b;Jiao et al, 2012). In this study, the concentrations and distribution of emerging pollutants PFASs were determined in soils from coastal and estuarine areas of the Bohai and Yellow Seas.…”

Occurrence and transport of 17 perfluoroalkyl acids in 12 coastal rivers in south Bohai coastal region of China with concentrated fluoropolymer facilities

“…petroleum hydrocarbons, heavy metals) to the Bohai Sea, the rivers contributed 50%e70% of the total inventory among the five sources: rivers, drains, atmospheric deposition, cultivation and non-point sources (Wang and Li, 2006). The authors have conducted systematic studies on PFAAs in the northern part of the Bohai coastal region since 2008, and found that PFAAs were widely distributed in the environmental matrices with PFOA dominant in the Northern Bohai coastal region (Wang et al, 2011b), PFOS was dominant in the aquatic products in Tianjin (Chen et al, 2011), PFAAs concentrations in surface water were correlated with the level of industrialization in Northern China (Wang et al, 2011a), Fluoropolymer production in the northern Bohai coastal region had posed potential impacts to local soils , and the PFOS emissions from industrial and domestic sources in the eastern coastal region of China were identified and estimated (Chen et al, 2009;Xie et al, 2013aXie et al, , 2013b. Results of the studies conducted by other researchers in the northern part also indicated the presence of great concentrations of PFAAs in river water, sediment, soil, precipitation, organisms and human blood from various sources including fluorine industry parks (Jin et al, 2007;Bao et al, 2009Bao et al, , 2010Liu et al, 2009;Li et al, 2011;Pan et al, 2011).…”
