Short chain chlorinated paraffins (SCCPs) are a group of complex emerging persistent organic pollutants. In this study, the uptake, translocation, and transformation of four constitutionally defined SCCP isomers were studied using whole pumpkin (Cucurbita maxima × C. moschata) and soybean (Glycine max L. Merrill) seedlings via hydroponic exposure. Results showed that the daughter SCCPs were C 10 Cl 5-8 and C 11-13 Cl 5-6. The metabolic transformation of all tested isomers included dechlorination and chlorine rearrangement. In addition, carbon chain decomposition products were found for isomers with trichlorinated carbon atoms (CCl 3-groups) in both pumpkin and soybean seedlings. This study provides the first evidence of carbon chain decomposition of SCCPs in whole plants, and it suggests new metabolism pathways of SCCPs in the environment. The influence of carbon chain length and degree of chlorination of SCCPs on their fate and behavior within different plant species were also investigated. Bioaccumulation of SCCPs in pumpkin and soybean increased with increasing carbon chain length and degree of chlorination. In comparison, soybean translocated and degraded parent SCCPs faster and to a greater extent than pumpkin, but pumpkin accumulated parent SCCPs to a greater extent than soybean. After 10 days exposure, less than 4% of the initial mass of exposed chemicals remained in solution of exposure groups. The parent chemicals accumulated in roots ranging from 23.6% to 59.9% for pumpkin and 1.98% to 54.5% for soybean and in stems ranging from 0.7% to 3.81% for *

“…68 Several studies have also investigated the uptake of PFASs into crops and earthworms from biosolids application. 69–71 In one study, concentration factors for roots relative to soil up to 4.7 and 10.3 were found for PFOS and PFOA, respectively, and all seven plants investigated displayed root concentration factors greater than one. 71 Elevated PFAS concentrations in meat and dairy products has also been reported, 57, 72 suggesting PFAS uptake from biosolids contaminated agriculture is a source of dietary exposure for farm animals.…”

Here we review present understanding of sources and trends in human exposure to poly- and perfluoroalkyl substances (PFASs) and epidemiologic evidence for impacts on cancer, immune function, metabolic outcomes, and neurodevelopment. More than 4000 PFASs have been manufactured by humans and hundreds have been detected in environmental samples. Direct exposures due to use in products can be quickly phased out by shifts in chemical production but exposures driven by PFAS accumulation in the ocean and marine food chains and contamination of groundwater persist over long timescales. Serum concentrations of legacy PFASs in humans are declining globally but total exposures to newer PFASs and precursor compounds have not been well characterized. Human exposures to legacy PFASs from seafood and drinking water are stable or increasing in many regions, suggesting observed declines reflect phase-outs in legacy PFAS use in consumer products. Many regions globally are continuing to discover PFAS contaminated sites from aqueous film forming foam (AFFF) use, particularly next to airports and military bases. Exposures from food packaging and indoor environments are uncertain due to a rapidly changing chemical landscape where legacy PFASs have been replaced by diverse precursors and custom molecules that are difficult to detect. Multiple studies find significant associations between PFAS exposure and adverse immune outcomes in children. Dyslipidemia is the strongest metabolic outcome associated with PFAS exposure. Evidence for cancer is limited to manufacturing locations with extremely high exposures and insufficient data are available to characterize impacts of PFAS exposures on neurodevelopment. Preliminary evidence suggests significant health effects associated with exposures to emerging PFASs. Lessons learned from legacy PFASs indicate that limited data should not be used as a justification to delay risk mitigation actions for replacement PFASs.

“…The PFAAs have been detected in fruits, vegetables, grains, and processed food products in Europe (Haug et al 2010;Herzke et al 2013) and North America (Ostertag et al 2009;Schecter et al 2010). Multiple studies have observed uptake and accumulation of PFAAs by plants from soils (Stahl et al 2009(Stahl et al , 2013Lechner and Knapp 2011;Felizeter et al 2012Felizeter et al , 2014Blaine et al 2013Blaine et al , 2014aBlaine et al , 2014bWen et al 2013Wen et al , 2014Wen et al , 2016Krippner et al 2014Krippner et al , 2015Bizkarguenaga et al 2016;Gobelius et al 2017;Navarro et al 2017). The influence of soil organic carbon on plant uptake of PFAAs has been evaluated; % organic carbon is a primary driver in PFAA availability (Blaine et al 2014b;Wen et al 2014;Bizkarguenaga et al 2016).…”

Although many studies have evaluated the fate of per‐ and polyfluoroalkyl acids (PFAAs) in aquatic environments, few have observed their fate in terrestrial environments. It has been proposed that ingestion could be a major PFAA exposure route for humans. We determined PFAA uptake in radish, carrot, and alfalfa under a maximum bioavailability scenario. Bioconcentration factors (BCFs) were determined in the edible tissue of radish (perfluorobutanesulfonate [PFBS] = 72; perfluorohexanesulfonate [PFHxS] = 13; perfluoroheptanoate [PFHpA] = 65; perfluorooctanoate [PFOA] = 18; perfluorooctanesulfonate [PFOS] = 2.9; and perfluorononanoate [PFNA] = 9.6), carrot (PFBS = 5.9; PFHxS = 1.1; PFHpA = 29; PFOA = 3.1; PFOS = 1; and PFNA = 1.4), and alfalfa (PFBS = 107; PFHxS = 12; PFHpA = 91; PFOA = 10; PFOS = 1.4; and PFNA = 1.7). Some of these PFAA BCFs are as much as 2 orders of magnitude higher than those measured previously in plants grown in biosolid‐amended soils. Environ Toxicol Chem 2019;38:2497–2502. © 2019 SETAC
