“…Similar findings have been reported in Canada [52], China [30,53], Ireland [54,55], Spain [56] and the United States [32,33,37,57,58], at generally similar concentrations, with one measurement near manufacturing activities at concentrations exceeding 290,000 ng/L (290 mg/kg) [53]. Carpet waste and clothing were determined [33] to be sources of biotransformation precursors of PFAS compounds in the aqueous phases of anaerobic landfill model reactors.…”

This review synthesises the available published research on interactions of per- and polyfluoroalkyl substances (PFAS) with landfill liners, with the view to inform on the expected behaviour of these persistent environmental pollutants in landfills. The review addresses the nature and significant types of PFAS compounds that are destined for landfills, as well as their by-product. It discusses the known and anticipated interactions with separate landfill liner components, namely geomembranes, geosynthetic clay liners and compacted clay liners. Various water-soluble PFAS are shown to advectively transport through geosynthetic clay liners (GCL) and showcase the limitations of relying on mineral liners alone to retain PFAS. Addition of activated carbon, while increasing saturated hydraulic conductivity, significantly increases PFAS retention by the GCL and reduced PFAS flux to manageable concentrations. An assessment of the relative risk for environmental exposure of different types of PFAS from landfills through interaction with those liner components is achieved with reference to published case studies of PFAS detection in and around landfills from Australia and around the World.

“…The concentration of BDE congeners in all the groundwater samples were higher when compared to previous studies (Streets et al, 2006;Wurl et al, 2006). Also, previous work on Predecelle River (France), Aire River (UK), electronic industrial water (China) and groundwater in Ireland (Harrad et al, 2020) had reported varying concentrations of ΣPBDEs but these are comparatively lower to the results obtained in this study (Labadie et al, 2010;Cristale et al, 2013;Jiang et al, 2014;Olutona et al, 2017;Harrad et al, 2020). Essumang et al (2018) reported BDE 100 as the most abundant congener, followed by BDE-99.…”

“…Dumpsites leachates is a heterogeneous mixture of persistent organic compounds and inorganic elements that are formed from interaction between excess water percolating through layers of waste in dumpsites (Kapelewska et al, 2016). Leachates in unlined dumpsites have been reported to contaminate groundwater (Nevondo et al, 2019;Harrad et al, 2020). The acute toxicity of leachate from selected dumpsites has been reported worldwide (Olujimi et al, 2016;Ancic et al, 2020).…”

Groundwater from the communities adjoining Abule Egba (ABE), Epe (EPE), Ikorodu (IKR), Olushosun (OSH) and Solous (SOL) dumpsites in Lagos State, Nigeria were collected and analyzed for Polybrominated diphenyl ethers. Water samples were extracted using liquid-liquid extraction followed by Gas Chromatography/Mass Spectroscopy analysis using already validated standard method. PBDEs concentrations ranged from 7.1 ± 10.1 (IKR) to 78 ± 109 µgL-1 (ABE) for BDE 28; 5.4 ± 0.3 (OSH) to 31.5 ± 27.3 µgL-1 (ABE) for BDE 47; 17 ± 24 (ABE) to 183 ± 226 µgL-1 for BDE 100; 11.7 ± 16.5 (ABE) to 174 ± 217 µgL-1(EPE) for BDE 99; 117 ± 166 (ABE) to 2034 ± 2819 µg L-1 (EPE) for BDE 183; 296 ± 392 (IKR) to 4283 ± 1278 µg L-1 (EPE) for BDE 209. BDE 153 and BDE 154 were not detected in all the water samples while BDE 28 was only detected in ABE and IKR water samples. The BDE 209 was the most dominant congener in all the water samples. The cumulative HI values for children through ingestion route ranged from 4.95 E+00 (SOL) to 4.53 E+01 (EPE) while in adult, it ranged from 4.25 E+00 (SOL) to 3.88 E+01 (EPE). This study confirmed the presence of PBDEs at elevated concentration in groundwater. Since there is no regular supply of pipe-borne water in the study area, residents consume the contaminated groundwater and may therefore be exposed to endocrine disrupting chemicals. Government should provide pie-borne water for the populace and discourage people from living close to the dumpsites.

“…Treatment methods for leachate include physical separation (adsorption, resin, and membrane filtration), oxidation, reduction, or thermolysis. Although landfills were intended to be the final stage in the PFAS lifecycle (Wei et al 2019;Lang et al 2017), research has demonstrated this is not the case (Harrad et al 2020;Ghisi et al 2019;Hepburn et al 2019;Riedel et al 2019). Outputs from landfills can contaminate water (leachate) and air, discussed in the liquid-phase and gas-phase sections of this review, respectively.…”
