“…Over 700 papers have now been published using DGT, with over 300 users in more than 30 countries. Building on this track record, DGT has been developed more recently to sample a range of organic chemicals, including antibiotics (Chen et al 2015a, Chen et al 2012, Chen et al 2013, household and personal care products (Chen et al 2017), polar organic contaminants (Challis et al 2016), anionic pesticides (Guibal et al 2017), bisphenols (Zheng et al 2015), phenol and 4-chlorophenol (Dong et al 2014a, Dong et al 2014b, glyphosate and aminomethyl phosphonic acid (Fauvelle et al 2015) and illicit drugs (Guo et al 2017). This paper develops DGT for a very important new set of selected endocrine disrupting compounds.…”

Diffusive gradients in thin-films (DGT) for in situ sampling of selected endocrine disrupting chemicals (EDCs) in waters

et al. 2018

A passive water sampler based on the diffusive gradients in thin-films (DGT) technique was developed and tested for 3 groups of endocrine disrupting chemicals (EDCs, including oestrogens, alkyl-phenols and bisphenols). Three different resins (hydrophilic-lipophilic-balanced (HLB), XAD18 and Strata-XL-A (SXLA)) were investigated for their suitability as the binding phase for DGT devices. Laboratory tests across a range of pH (3.5-9.5), ionic strength (0.001-0.5 M) and dissolved organic matter concentration (0-20 mg L) showed HLB and XAD18-DGT devices were more stable compared to SXLA-DGT. HLB-DGT and XAD18-DGT accumulated test chemicals with time consistent with theoretical predictions, while SXLA-DGT accumulated reduced amounts of chemical. DGT performance was also compared in field deployments up to 28 days, alongside conventional active sampling at a wastewater treatment plant. Uptake was linear to the samplers over 18 days, and then began to plateau/decline, indicating the maximum deployment time in those conditions. Concentrations provided by the DGT samplers compared well with those provided by auto-samplers. DGT integrated concentrations over the deployment period in a way that grab-sampling cannot. The advantages of the DGT sampler over active sampling include: low cost, ease of simultaneous multi-site deployment, in situ analyte pre-concentration and reduction of matrix interferences compared with conventional methods. Compared to other passive sampler designs, DGT uptake is independent of flow rate and therefore allows direct derivation of field concentrations from measured compound diffusion coefficients. This passive DGT sampler therefore constitutes a viable and attractive alternative to conventional grab and active water sampling for routine monitoring of selected EDCs.

“…Sample analysis methodology was adapted from previous studies (Fauvelle et al, 2015;Freuze et al, 2007). Briefly, analysis was performed on HPLC-MS/MS using an AB/Sciex API6500+Q mass spectrometer (Sciex, Concord, Ontario, Canada) equipped with an electrospray (TurboV) interface coupled to a Shimadzu Nexera HPLC system (Shimadzu Corp., Kyoto, Japan).…”

“…Subsequently, passive sampling methods were adapted for the monitoring of ionizable organic compounds in water systems (Fauvelle et al, 2014, Kaserzon et al, 2014Li et al, 2011). Aiming to target PMG and AMPA, a previous study adapted the Diffusive Gradient in Thin-film (DGT) passive sampling technique with a TiO 2 receiving phase (Fauvelle et al, 2015), while another adapted the POCIS design using molecularly imprinted polymer (MIP) as a receiving phase (Berho et al, 2017). Both TiO 2 and MIP sorption phases successfully accumulated these analytes.…”

“…However, limitations of the developed sampling tools include: i) the low sampling rates (R s ) achieved for PMG and AMPA with the DGT based sampler, i.e. around 10 mL day -1 (Fauvelle et al, 2015), which affects the sensitivity and applicability of the sampler under environmental conditions ii) the dependency of the analytes flux and sampling rates on the external water velocity (i.e., water boundary layer thickness; WBL) with the POCIS based sampler, which…”

Glyphosate (PMG) is one of the most widely used herbicides with a reported 8.6 million tons applied globally in 2016. Due to widespread use and limited understanding of long-term environmental impacts, it is expected that future monitoring requirements for PMG and its primary metabolite aminomethyl phosphonic acid (AMPA) in aquatic environments will increase, along with the need for low cost monitoring and risk assessment strategies. The aim of this study was to investigate a microporous polyethylene tube (MPT; 2-mm thickness, 17.6 cm surface area, 35% porosity, 2.5 μm pore size) as a diffusive layer for the passive sampling of PMG and AMPA. Levels of PMG and AMPA sorbed to MPT were low (K close to 1 mL g), validating MPT as a diffusive layer. Uptake experiments were conducted first under controlled laboratory conditions (pH = 6.8, 6 days), followed by an in situ freshwater lake system deployment (pH = 7.3, 11 days). PMG and AMPA accumulated linearly (slope relative standard deviation < 6%) under laboratory conditions with sampling rates (R) of 18 and 25 mL d, respectively. PMG in situ R was 28 mL d, and was not different from the one found in the laboratory. AMPA was below the limit of quantification (LOQ, 1 ng mL) in grab water samples, but was detected (>LOQ) in all passive samplers. Results illustrate the gain in sensitivity provided by the passive sampling technique, and the applicability of the device developed for the passive sampling of PMG and AMPA.

“…By then, a considerable number of passive samplers have been developed for medium polar contaminants: MESCO (Membrane-Enclosed Silicone Collector; Paschke et al, 2006), LDPE (Low-Density Polyethylene; Müller et al, 2001), SR (Silicone Rubber; Rusina et al, 2010), Chemcatcher® (Kingston et al, 2000), POCIS (Polar Organic Chemical Integrative Sampler; Alvarez et al, 2004). Several recent developments reported the adaptation of POCIS and DGT for the sampling of highly polar compounds such as antibiotics (e.g., sulfamethoxazole), perfluorinated chemicals, and pesticides (e.g., glyphosate, 2,4-D) (Fauvelle et al, 2012, 2015; Chen et al, 2013; Kaserzon et al, 2014a). …”

Complexity of contaminants exposure needs to be taking in account for an appropriate evaluation of risks related to mixtures of pesticides released in the ecosystems. Toxicity assessment of such mixtures can be made through a variety of toxicity tests reflecting different level of biological complexity. This paper reviews the recent developments of passive sampling techniques for polar compounds, especially Polar Organic Chemical Integrative Samplers (POCIS) and Chemcatcher® and the principal assessment techniques using microalgae in laboratory experiments. The progresses permitted by the coupled use of such passive samplers and ecotoxicology testing as well as their limitations are presented. Case studies combining passive sampling devices (PSD) extracts and toxicity assessment toward microorganisms at different biological scales from single organisms to communities level are presented. These case studies, respectively, aimed (i) at characterizing the “toxic potential” of waters using dose-response curves, and (ii) at performing microcosm experiments with increased environmental realism in the toxicant exposure in term of cocktail composition and concentration. Finally perspectives and limitations of such approaches for future applications in the area of environmental risk assessment are discussed.
