“…Heavily polluted surface and ground water used for irrigation might pose risks due to PFAAs in soils and subsequent accumulation into crops and vegetables and eventual accumulation in humans (Blaine et al, 2014;Wen et al, 2014). Local surface water and groundwater are believed to be also used for poultry farming and aquaculture.…”

Perfluoroalkyl acids (PFAAs) can be released to water bodies during manufacturing and application of PFAA-containing products. In this study, the contamination pattern, attenuation dynamics, sources, pathways, and risk zoning of PFAAs in surface and ground water was examined within a 10 km radius from a mega-fluorochemical industrial park (FIP). Among 12 detected PFAAs, perfluorooctanoic acid (PFOA) dominated, followed by shorter-chained perfluoroalkyl carboxylic acids (PFCAs). PFAA-containing waste was discharged from the FIP, with levels reaching 1.86 mg/L in the nearby rivers flowing to the Bohai sea together with up to 273 μg/L in the local groundwater in the catchment. These levels constitute a human health risks for PFOA and other shorter-chained PFCAs within this location. The concentrations of ∑PFAAs in surface water strongly correlated with the local groundwater. The dominant pollution pathways of PFAAs included (i) discharge into surface water then to groundwater through seepage, and (ii) atmospheric deposition from the FIP, followed by infiltration to groundwater. As the distance increased from the source, PFAAs levels in groundwater showed a sharp initial decrease followed by a gentle decline. The contamination signal from the FIP site on PFAAs in groundwater existed within a radius of 4 km, and at least 3 km from the polluted Dongzhulong River. The major controlling factor in PFAA attenuation processes was likely to be dilution together with dispersion and adsorption to aquifer solids. The relative abundance of PFOA (C8) declined while those of shorter-chained PFCAs (C4-C6) increased during surface water seepage and further dispersion in groundwater.

“…Perfluoroalkyl compounds (PFASs) are used in, or derived from, nonstick cookware, stain-resistant textiles, coatings on food packaging, components of fire-fighting foam and in many industrial applications including metal plating, hydraulic fluids and surfactants. These compounds are of interest as they have a degree of water solubility [8] and they can therefore be taken up by crops e.g., [9,10]. Polychlorinated napthalenes (PCNs) have dioxin-like properties, and are used in applications such as dielectric fluids, engine oil additives and lubricants [5].…”

Organic Contaminant Content and Physico-Chemical Characteristics of Waste Materials Recycled in Agriculture

A range of wastes representative of materials currently applied, or with future potential to be applied, to agricultural land in the UK as fertilisers and soil improvers or used as animal bedding in livestock production, were investigated. In addition to full physico-chemical characterization, the materials were analysed for a suite of priority organic contaminants. In general, contaminants were present at relatively low concentrations. For example, for biosolids and compost-like-output (CLO), concentrations of polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDD/Fs) and polychlorinated biphenyls (PCBs) were approximately 1−10 and 5-50 times lower, respectively, than various proposed or implemented European limit values for these contaminants in biosolids or composts applied to agricultural land. However, the technical basis for these limits may require re-evaluation in some cases. Polybrominated, and mixed halogenated, dibenzo-p-dioxins/dibenzofurans OPEN ACCESSAgriculture 2015, 5 1290 are not currently considered in risk assessments of dioxins and dioxin-like chemicals, but were detected at relatively high concentrations compared with PCDD/Fs in the biosolids and CLOs and their potential contribution to the overall toxic equivalency is assessed. Other 'emerging' contaminants, such as organophosphate flame retardants, were detected in several of the waste materials, and their potential significance is discussed. The study is part of a wider research programme that will provide evidence that is expected to improve confidence in the use of waste-derived materials in agriculture and to establish guidelines to protect the food chain where necessary.

“…Within the PFAS group, perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) are the most commonly used and found compounds (Arvaniti and Stasinakis, 2015). Up until now, PFOS and PFOA have been detected in all environmental and biological matrices, including the atmosphere Ahrens et al, 2011;Dreyer et al, 2009), soil (Kim et al, 2015;Wen et al, 2014;Washington et al, 2010), water (Eschauzier et al, 2010;Bossi et al, 2008), sediment (Kwadijk et al, 2010), biota (Houde et al, 2011), and human serum (Gao et al, 2015). Adverse effects of PFOS and PFOA on plants, animals and humans have been reported (Wen et al, 2013;Stevenson et al, 2006).…”

“…Industrial and municipal wastewater treatment plants (WWTPs) are significant sources for dispersing PFASs into the environment (Kim et al, 2015;Wen et al, 2014;Washington et al, 2010;Bossi et al, 2008). High concentrations of PFASs have been found in the sludge from WWTPs (Vierke et al, 2013;Sun et al, 2011;Higgins et al, 2005).…”

a b s t r a c tThe roles of protein and lipid in the accumulation and distribution of perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) in seven species of plants from biosolids-amended soils were investigated. The PFOS and PFOA root concentration factors (C root /C soil ) ranged from 1.37 to 4.68 and 1.69 to 10.3 (ng/g root )/(ng/g soil ), respectively, while the translocation factors (C shoot /C root ) ranged from 0.055 to 0.16 and 0.093 to 1.8 (ng/g shoot )/(ng/g root ), respectively. The PFOS and PFOA accumulations in roots correlated positively with root protein contents (P < 0.05), while negatively with root lipid contents (P < 0.05). These suggested the promotion effects of protein and inhibition effects of lipid on root uptake. The translocation factors correlated positively with the ratios between protein contents in shoots to those in roots (P < 0.05), showing the importance of protein on PFOS and PFOA translocation. This study is the first to reveal the different roles of protein and lipid in the accumulation and distribution of PFOS and PFOA in plants.
