“…Besides, the global warming potential of PFCs is thousands of times stronger than CO 2 (Hou, 2015; X. Li et al, 2016). Asphalt fume contains a complex mixture of compounds and substances, including phenols and benzopyrene, that are harmful to humans, animals, and plants (P. Li et al, 2019). Chinese aluminum industry generally emits small amounts of fluorine and asphalt fume; however, the emission intensity of these two pollutants is high in certain regions, which may adversely influence local agricultural and animal husbandry industries, causing severe air and water pollution and eventually soil pollution.…”

“…PFAS production or use in manufacturing can lead to PFAS additions to agricultural soils through atmospheric deposition and/or contaminating water used for irrigation. Soil samples in agricultural fields located in five cities near fluorochemical manufacturing sites were commonly found to contain PFAS with detection frequency of PFBA (18.2%) > PFOA (31.8%), > PFDA (11.4%) > PFNA(12.6%) [66]. Liu et al [36] reported total PFAS concentrations in agricultural soils of 79.9 to 200 ng/g and 2.09 to 3.75 ng/g within 0.3 km and 10 km, respectively, of a fluorochemical plant.…”

Purpose of Review Per- and polyfluoroalkyl substances (PFAS) are a family of > 4700 recalcitrant compounds, many of which are ubiquitous in the environment. This review aims to (1) identify PFAS sources and fate processes relevant to agricultural systems and (2) expand on plant uptake mechanisms and plant responses to PFAS. Recent Findings The number of PFAS being quantified in studies involving soil, water, and plants is increasing. Transformation of precursors that tend to stay in the rhizosphere can lead to long-term PFAS reservoir to plants. Some PFAS are readily taken up, particularly the shorter-chain PFAS, and can evoke metabolic responses and phytotoxic effects at high concentrations. PFAS translocation from roots to shoots occurs through both active and passive transport mechanisms. Both PFAS uptake and effects vary between and within species. Summary As new PFAS emerge, it will be necessary to continue expanding the list of PFAS quantified in land-applied media and assessing their accumulation potential in plants. While controlled laboratory or greenhouse studies have merit, comprehensive field studies are needed to provide clarity on PFAS fate and their relative risk in agricultural systems. Field studies should include identifying site-specific PFAS sources, quantifying a broader suite of PFAS and identifying potential precursors, evaluating plant uptake of replacement PFAS, reporting of soil properties and climatic conditions, and assessing risk of impacts to source and irrigation waters. This information can be utilized to inform future studies towards evaluating and mitigating risks to our food chain associated with PFAS in agricultural systems.

“…Nevertheless, as the ultimate receptor of PFASs, humans are exposed to more pollution sources [12,35] For example, the HR of PFASs in PM 10 in Bohai area were 1.80×10 -7~4 .04×10 -5 [40], and HRs of PFASs in soil, groundwater and tap water was lower than the risk value [41]. The EDI values of PFOS and PFOA in fatty shes and shell sh in six coastal cities in China were no more than 0.001 μg/kg/day, which is considerably lower than the acceptable daily intake values of 0.15 μg/kg/day and 1.5 μg/kg/day for PFOS and PFOA, respectively [10].…”

ObjectiveThe purpose of this investigation was to monitor the contamination characters and spatial and temporal distributions of 23 Perfluorinated alkyl substances (PFASs) in seafood along South China Coastal Regions. The exposure risks of PFOA and PFOS to human health in marine aquatic products were also evaluated.MethodsA total of 844 samples including 359 fishes, 391 shellfishes and 94 crustaceans were collected from Guangdong, Guangxi and Hainan provinces. The samples were extracted and purified using a modified QuEChERS procedure and analyzed by UPLC-MS / MS. The statistical analysis was performed in view of the detection of different PFAS components in variety of fishes, shellfishes and crustaceans, respectively.ResultsSixteen PFASs were detected in the survived samples and the total detection rates reached to 99.21 %. The highest ∑PFASs in each sample was 28.27 μg/kg, and the average and medium values of ∑PFAS were 1.83 μg/kg and 1.18 μg/kg, respectively. PFOS and PFBA have been considered as predominant PFAS components with corresponding pollution contribution rates of 29.14% and 24.71%, respectively. However, it is noted that PFNA and PFBS were primarily enriched in the oyster and mussel. During the period of this investigation (2014-2016), ∑PFAS average concentrations turned out constantly rising trend and new pollution component PFHxS detected in 2016. ∑PFAS concentrations of Guangdong, Guangxi and Hainan provinces were approximately at similar level.ConclusionThe contamination status of PFASs were getting worse in South China Coastal Regions. Safety and risk exposure assessments of PFOA and PFOS via daily diet intakes showed relatively low to local residents.
