“…Compared to PFASs contamination in leachates from Australia, our results are similar to the PFASs concentration detected by Gallen et al (2016) in eight closed landfill sites (1365 ng/L). However, they are lower than the PFASs (16) found by Gallen et al (2016) in 6 operational sites in Australia (5254 ng/L), the PFASs (16) reported in leachates from U.S. by Allred et al (2016) in 6 landfill sites (6156 ng/L) or by Huset et al (2011) in four lined landfill sites in U.S. (2253-6157 ng/L). In the last case, landfill sites received biosolids from WWTP to be disposed of together with the domestic wastes, and in the study by Allred et al (2014) some of the studied sites also accepted biosolids.…”

Perfluorinated alkyl substances (PFASs) in northern Spain municipal solid waste landfill leachates

Landfill leachates have been recognized as significant secondary sources of poly- and perfluoroalkyl substances (PFASs). This study presents data on the occurrence and concentration of 11 perfluoroalkyl carboxylates (PFCAs) and 5 perfluoroalkyl sulfonates (PFSAs) in leachates from 4 municipal solid waste landfill sites located across northern Spain. To the best of our knowledge, this is the first report of the presence of PFASs in Spanish landfill leachates. Two of the landfill sites applied on-site treatment using membrane bioreactors (MBR), and its effect on PFASs occurrence is also reported. Total PFASs (∑PFASs) in raw leachates reached 1378.9 ng/L, while in treated samples ∑PFASs was approximately two-fold (3162.3 ng/L). PFCAs accounted for the majority of the detected PFASs and perfluorooctanoic acid (PFOA) was the dominant compound in raw leachates (42.6%), followed by shorter chain PFHxA (30.1%), PFPeA and PFBA. The age of the sites might explain the PFASs pattern found in raw leachates as all of them were stabilized leachates. However, PFASs profile was different in treated samples where the most abundant compound was PFHxA (26.5%), followed by linear perfluorobutane sulfonate (L-PFBS) (18.7%) and PFOA (17.7%). The overall increase of the PFASs content as well as the change in the PFASs profile after the MBR treatment, could be explained by the possible degradation of PFASs precursors such as fluorotelomer alcohols or fluorotelomer sulfonates. Using the volume of leachates generated in the landfill sites, that served 1.8 million people, the discharge of 16 ∑PFASs contained in the landfill leachates was estimated as 1209 g/year.

“…All the studies performed in Europe correspond to northern and central European countries. Recently, a study on PFASs has been published dealing with landfill leachates in Australia (Gallen et al, 2016). The number of PFASs monitored varies from one study to another.…”

“…Nonetheless, the global comparison of the findings from the present study further confirms the ubiquitous distribution of the targeted BFRs, especially the PBDEs. As shown in Table 3, the sum PBDEs in the present study were generally higher than those previously reported for raw and treated leachate in China, Japan and South Africa (Huang et al 2013, Odusanya et al 2009, Osako et al 2004), but were similar to those reported for some Chinese landfill sites (Li et al 2014), while the reported levels of the sum PBDEs for some Australian and South African landfill sites (Daso et al 2013, Gallen et al 2016 were significantly higher than those observed in the present study. Furthermore, the levels of HBCDD observed in the present study were also generally higher than those previously reported.…”

The occurrence of selected brominated flame retardants, including nine polybrominated diphenyl ether (PBDE) congeners, hexabromocyclododecane (HBCDD) and tetrabromobisphenol A (TBBPA) in leachate samples from eight landfill sites in South Africa, were investigated. In addition, the possible influences of dissolved organic carbon on their levels were also evaluated. Filtered leachate samples were subjected to solid-phase extraction to isolate the various target compounds. PBDEs with six bromine substituents and above, as well as α-HBCDD, β-HBCDD and TBBPA, were generally found below the detection limit. However, the mean value of the total lower PBDE congeners ranged between 0.04 and 0.48 μg L, and the concentrations of γ-HBCDD ranged from not detectable (ND) to 0.05 μg L. No significant correlation was observed between the target compounds and dissolved organic carbon, although weak to moderate correlations were mostly observed for the lower PBDEs.

“…The use of ultrapure water and acid-washed sand as laboratory control samples may not adequately represent WWTP matrices (and the associated interferences) and present some uncertainty with analytical results. However, similar methods have been successfully employed in WWTP matrices in other studies [32, 46, 47] and overall we considered the QA/QC results provided an acceptable assurance of the quality of the data set for this study.…”

Quantifying the emissions of per- and polyfluoroalkyl substances (PFAS) from Australian wastewater treatment plants (WWTP) is of high importance due to potential impacts on receiving aquatic ecosystems. The new Australian PFAS National Environmental Management Plan recommends 0.23 ng L −1 of PFOS as the guideline value for 99% species protection for aquatic systems. In this study, 21 PFAS from four classes were measured in WWTP solid and aqueous samples from 19 Australian WWTPs. The mean ∑ 21 PFAS was 110 ng L −1 (median: 80 ng L −1 ; range: 9.3–520 ng L −1 ) in aqueous samples and 34 ng g −1 dw (median: 12 ng g −1 dw; range: 2.0–130 ng g −1 dw) in WWTP solids. Similar to WWTPs worldwide, perfluorocarboxylic acids were generally higher in effluent, compared to influent. Partitioning to solids within WWTPs increased with increasing fluoroalkyl chain length from 0.05 to 1.22 log units. Many PFAS were highly correlated, and PCA analysis showed strong associations between two groups: odd chained PFCAs, PFHxA and PFSAs; and 6:2 FTS with daily inflow volume and the proportion of trade waste accepted by WWTPs (as % of typical dry inflow). The compounds PFPeA, PFHxA, PFHpA, PFOA, PFNA, and PFDA increased significantly between influent and final effluent. The compounds 6:2 FTS and 8:2 FTS were quantified and F–53B detected and reported in Australian WWTP matrices. The compound 6:2 FTS was an important contributor to PFAS emissions in the studied Australian WWTPs, supporting the need for future research on its sources (including precursor degradation), environmental fate and impact in Australian aquatic environments receiving WWTP effluent.
