“…The dominance of PFOA in soils was similar to a study by Filipovic et al (2015b) in which the relative contribution of PFOA in the soil, polluted due to historical usage of aqueous film forming foam, was higher than the one of PFHxA. PFOA was also the dominant PFCA in soils, collected near a fluorochemical industrial park in eastern China (Lu et al, 2018).…”

“…The PFSA concentrations were higher than the PFCA concentrations in Europe (Rankin et al, 2016), which is in agreement with our results, as PFOS concentrations were much higher than those of any other analyte. The PFOA concentrations in the soil (62.5 ng/g) collected from a fluorochemical industrial park in China (Lu et al, 2018) were higher than those at 3M in Antwerp.…”

Perfluoroalkylated acids (PFAAs) are persistent chemicals that have been detected globally in the environment and in wildlife. Although it is known that PFAAs sorb to solid matrices, little is known on PFAA concentrations in soils. PFAA pollution has often been studied in aquatic invertebrates. However, this has rarely been done on terrestrial species. In the present study, we examined whether the concentrations of 15 PFAAs in isopods (Oniscidae), collected at a fluorochemical plant and in four other areas, representing a gradient in distance from the pollution source (1 km to 11 km), were related to those in the soil and in eggs of a songbird, the great tit (Parus major), collected in the same areas. Additionally, we examined the effect of physicochemical properties such as total organic carbon (TOC) and clay content on the relationship between the concentrations in soil and isopods. Finally, we examined the composition profile in the soil and isopods.Mean PFOS and PFOA concentrations of 1700 ng/g dw and 24 ng/g dw were detected in the soil at the plant. PFOS and PFPeA were the dominant PFAAs in isopods and were detected at mean concentrations of 253 and 108 ng/g ww, respectively. The great tit eggs showed elevated mean PFOS concentrations of 55970 ng/g ww. In most cases, PFAA concentrations decreased with increasing distance from the plant.As PFAA concentrations in isopods were correlated with concentrations in the soils, isopods could serve as a bioindicator for PFAA concentrations in soils. Additionally, there were indications that isopods could also serve as a bioindicator for PFAA concentrations in eggs of great tits. However, these indications were only the case at two locations, showing the need to further monitor the possibilities of using isopods as a bioindicator for PFAA concentrations in song bird eggs.

“…These concentrations are within the range of those reported in other international studies. The PFBA concentrations in surface soil near a fluorochemical park in China (0.6 ng g -1 dw, Lu et al, 2018) were similar to those observed at Vlietbos, but lower than those observed at Middenvijver-Rot and Burchtse Weel. The PFOA (50.1 ng g -1 dw) and PFOS (2583 ng g -1 dw) concentrations at a fluorochemical manufacturing facility in Wuhan, China were higher than those reported in the present study at 3M, whereas the concentrations of PFOA (0.79 ng g -1 dw) and PFOS (7.06 ng g -1 dw) near a fluorochemical plant in Hubei Province, China were similar (Wang et al, 2010).…”

“…As a consequence of these major sources of PFAS, these compounds are almost ubiquitously detected in the environment (Xiao et al, 2015;Lu et al, 2018). Research has indicated that soil organic carbon content is the dominant solid-phase parameter which affects the adsorption of PFAS.…”

Per- and polyfluoroalkyl substances (PFAS) are Synthetic Organic Compounds (SOCs) which are of current concern as they are linked to a myriad of adverse health effects in mammals. They can be found in drinking water, rivers, groundwater, wastewater, household dust, and soils. In this review, the current challenge and status of bioremediation of PFAs in soils was examined. While several technologies to remove PFAS from soil have been developed, including adsorption, filtration, thermal treatment, chemical oxidation/reduction and soil washing, these methods are expensive, impractical for in situ treatment, use high pressures and temperatures, with most resulting in toxic waste. Biodegradation has the potential to form the basis of a cost-effective, large scale in situ remediation strategy for PFAS removal from soils. Both fungal and bacterial strains have been isolated that are capable of degrading PFAS; however, to date, information regarding the mechanisms of degradation of PFAS is limited. Through the application of new technologies in microbial ecology, such as stable isotope probing, metagenomics, transcriptomics, and metabolomics there is the potential to examine and identify the biodegradation of PFAS, a process which will underpin the development of any robust PFAS bioremediation technology.
