“…Hence, the downwind location may be the main reason for higher concentrations of PFAAs at the sites in the west. So air transport and deposition was the most likely pathway for PFAAs from the FIP to the households in the surrounding areas, which is similar to the APFO transportation in environmental media near a fluorochemical manufacturing facility (Davis et al, 2007).…”

The manufacture of fluorochemicals can lead to high levels of perfluoroalkyl acids (PFAAs) contaminating the surrounding environment and consequently elevated exposure to the local residents. In this study, measurements of PFAAs associated with indoor and outdoor dusts around a mega fluorochemical industrial park (FIP) were made. Perfluorooctanoic acid (PFOA) and short-chain perfluoroalkyl carboxylic acids (C4-C7 PFCAs) were the predominant forms in all samples. The signature of the PFAAs in dusts in the local area matched that found within the FIP complex. The contamination plume in the local area could be linked to the prevailing wind direction starting from the FIP. The dust concentrations decreased exponentially with distance from the FIP (noticeably in the first 5 km). PFAAs contamination could be detected at the furthest location, 20 km away from the FIP. The concentrations of PFAAs were higher in indoor dust (73-13,500 ng/g, median: 979 ng/g) than those in outdoor dust (5-9495 ng/g, median: 62 ng/g) at every location. The highest estimated daily intake of PFOA via dust ingestion (26.0 ng/kg·bw/day) was for toddlers (2-5 years) living 2 km away from the FIP, which is posing human health risk, though exposure remains within the provisional tolerable daily intake values.

“…This indicated that these compounds may have a common source or similar transformation mechanism in soil. However, some studies showed that PFCs such as PFOA will not significantly retained by geo-solids, once they are emitted to land, they will be rapidly transferred to surface water or shallow groundwater (Davis et al 2007) and ultimately to the oceans. Thus, a long-term study is essential to get well knowledge of the PFCs contamination in soil in Tianjin.…”

Detectable PFCs could be found in all samples. Perfluorooctanoic acid (PFOA) was the major PFC in river water, while perfluorooctane sulfonate (PFOS) was dominant in sediment and were 17-to 153-fold higher than those in water. PFCs concentrations in soil were little higher than those in sediment. In fish muscles PFOS showed the highest concentrations. Generally, PFC concentrations in fish were in the following rank order: crucian carp [ silver carp[ common carp. We suggested that there may be constant and diffuse pollution sources in Tianjin. Point sources also appeared to make significant contribution in the present study.

“…In our field survey, we found that there were many small irrigation canals with large areas of farmland in the downstream of the Xiaoqing River Basin. It was also found that PFAAs, especially PFOA can migrate downward with river discharge into the underlying aquifer [5]. So the missing masses of PFAAs could be lost via horizontal flow into irrigation canals and vertical migration to the underlying aquifer.…”

“…This increase in PFBS has been observed in sediment cores from Lake Michigan [4], which is to the west of the 3 M facility. At another fluoropolymer facility owned by DuPont located in West Virginia, concentrations of PFOA as great as 78 g/L have been observed in groundwater [5]. This has brought high concerns for health of local residents and they have been supplied with alternative sources of water [22].…”
