“…Thus, it is reasonable to suggest that the long-chain PFOA and PFOS would be the main composition, whereas short-chain PFASs would be dominated in aboveground plant tissues. Kim et al. (2019) investigated the uptake of PFASs from soil by rice and analyzed the relative distribution patterns of PFASs in each matrix ( Figure 3 ).…”

“…(2019) investigated the uptake of PFASs from soil by rice and analyzed the relative distribution patterns of PFASs in each matrix ( Figure 3 ). They found that the composition of PFCA with ≤8 carbons and >8 carbons were similar (44.4% and 40.4%, respectively) in soil ( Kim et al., 2019 ), whereas in the void water, PFCA with ≤8 carbons was the dominant form (83.8%). In brown rice, PFOA was the most predominant form (86.7%), relative to other PFCAs.…”

“…A wide number of reports have detected PFOA and PFOS in soil, water, biota, and food all over the globe. These studies identified contamination from historic and recent PFAS usage, as well as identifying direct and/or indirect human exposure in Europe (Kowalczyk et al 2012;Toft et al 2012;Flores et al 2013;Filipovic et al 2015;Lindim et al 2016), the Americas (Olsen et al 2012;Geiger et al 2014;Rankin et al 2016;Harris et al 2017;Olsen et al 2017), Australia (Baduel et al 2014;Toms et al 2014;Gomis et al 2017;Gallen et al 2018;O'Connor et al 2018), Antarctica (Bengtson et al 2010;Cai et al 2012;Llorca et al 2012), Africa (Hanssen et al 2010;Essumang et al 2017;Verhaert et al 2017;Groffen et al 2018), and Asia (Fujii et al 2012;Lee et al 2013b;Choi et al 2017;Kim and Kim 2018;Kim et al 2019;Li et al 2020).…”

This study performed the first environmental and dietary exposure assessment to explore plant uptake of perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) from agricultural soil and irrigation water in the Nakdong River delta, South Korea. Annual average concentrations of total PFOA and PFOS ranged from 0.026 to 0.112 µg L -1 (irrigation water), and from 0.818 to 1.364 µg kg -1 (soil), respectively. PFOA and PFOS hotspots were identified downstream of the Nakdong River, and were influenced by seasonal climatic variations. The observed average biennial concentration of the sum of PFOA and PFOS decreased in irrigation water, from 0.112 µg L -1 in 2013 to 0.026 µg L -1 in 2015, suggests that the 2013 Persistent Organic Pollutants Control Act may have helped to reduce levels of PFAS at this location. This study calculated some of the highest plant uptake factors reported to date, with values ranging from 0.962 in green onions to < 0.004 in plums. Leafy vegetables and rice are important components of the Korean diet; these groups had the largest contribution to the estimated dietary intake of PFOA and PFOS, which was calculated at 0.449 and 0.140 ng kgbw -1 day -1 , respectively. This corresponded to 66.4% for PFOA and 7.9% for PFOS of the EFSA reference dose (RfD). The dietary intake of PFOA and PFOS from crops alone did not exceed the RfD. However, when the estimated daily intake (EDI) from other sources such as tap water, meat, fish, dairy and beverages were included in the exposure risk assessment, both of the EDIs to PFOA and PFOS exceeded the RfDs, indicating there may be a risk to human health. This study concludes that consumption of crops might, therefore, be a significant and underappreciated pathway for human exposure to PFAS.

“…However, it would be difficult to propose the environmental guideline for agricultural soil and water unless the study on crops uptake of PFOA and PFOS from soil environment is supported. To solve this problem, plant uptake factors (PUFs) or bioconcentration factors of PFOA and PFOS were reported in several crops such as carrot, cucumber, lettuce, maize, potato, radish, rice and wheat [7,11,19,22,37]. However, the plant uptake potentials of PFAAs were studied limitedly and there was still needed to study on various food crops.…”

The long-chained perfluoroalkyl acids (PFAAs), perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), are a potential exposure risk in the environment, specifically for humans due to high levels of bioaccumulation, persistence, and toxicity. In the current study, the plant uptake factors (PUFs) of spinach and Welsh onion were investigated on the three different concentration levels of PFOA and PFOS in soil. Spinach and Welsh onion were divided into three residue groups, a control group and two levels of PFOA and PFOS. The PFAAs spiked soils were aged for six months and the extractable residue of PFOS in the aged soil was reduced to 30-59% of the initial spiked concentrations for PFOS, while PFOA showed almost the same initial spiked concentrations. The PUFs for PFOA and PFOS were 0.111-2.821 and 0.047-3.175 for spinach, and 0.203-0.738 and 0.035-0.181 for Welsh onion, respectively. The highest PUF values in both vegetable were displayed when the residual concentration of PFAAs were part-per-billion (ppb) or sub-ppb in soil.
