Diffusive-Gradient Passive Samplers for Per- and Polyfluoroalkyl Substances.

Per- and polyfluoroalkyl substances (PFAS) are chemical pollutants of growing concern. Due to their ubiquity, persistence in the environment, and potential for toxicity at low environmental concentrations, it is necessary to have convenient and reliable methods to measure PFAS in natural waters. Passive sampling methods (in situ pre-concentration of PFAS) are investigated for monitoring purposes. The following dataset specifically deals with the calibration and application of a diffusive gradient in thin film (DGT) passive sampler, as well as comparisons to previously designed microporous polyethylene tube (MPT) passive samplers and water grab samples. Concentrations are measured with tandem liquid-chromatography mass spectrometry (LC-MS/MS) for all sampling methods. The dataset comprises: (i) a list of 25 PFAS compounds considered for the study at hand, (ii) method detection limits of considered PFAS compounds, (iii) calibration experiments of the DGT passive sampler, as well as results from modelling approaches to determine sampling rates, (iv) lab deployment of the developed DGT to challenge determined sampling rates, (v) field deployments of the developed DGT in an assortment of streams, ponds, and lakes in Minnesota and Maine, where concentrations of PFAS compounds are compared to concentrations measured by MPT, and water grab samples.

Field Validation of a Novel Passive Sampler for Dissolved PFAS in Surface Waters

Abstract Numerous per- and polyfluoroalkyl substances (PFAS) are of growing concern worldwide due to their ubiquitous presence, bioaccumulation and adverse effects. Surface waters in the United States have displayed elevated concentrations of PFAS, but so far discrete water sampling has been the commonly applied sampling approach. In the present study we field-tested a novel integrative passive sampler, a microporous polyethylene tube, and derived sampling rates (Rs) for nine PFAS in surface waters. Three sampling campaigns were conducted, deploying polyethylene tube passive samplers in the effluent of two wastewater treatment plant (WWTP) effluents and across Narragansett Bay (Rhode Island, USA) for 1 month each in 2017 and 2018. Passive samplers exhibited linear uptake of PFAS in the WWTP effluents over 16–29 days, with in situ Rs for nine PFAS ranging from 10 ml day−1 (perfluoropentanoic acid) to 29 ml day−1 (perfluorooctanesulfonic acid). Similar sampling rates of 19 ± 4.8 ml day−1 were observed in estuarine field deployments. Applying these Rs values in a different WWTP effluent predicted dissolved PFAS concentrations mostly within 50% of their observations in daily composite water samples, except for perfluorobutanoic acid (where predictions from passive samplers were 3 times greater than measured values), perfluorononanoic acid (1.9 times), perfluorodecanoic acid (1.7 times), and perfluoropentanesulfonic acid (0.1 times). These results highlight the potential use of passive samplers as measurement and assessment tools of PFAS in dynamic aquatic environments.

Uptake of Per- and Polyfluoroalkyl Substances by Fish, Mussel, and Passive Samplers in Mobile Laboratory Exposures using Groundwater from a Contamination Plume at a Historical Fire Training Area, Cape Cod, Massachusetts - Chemical and Biological Data from August to September 2018

This data release presents chemical and biological results from an investigation of the uptake of per- and polyfluoroalkyl substances (PFAS) from groundwater contaminated by fire training activities on Cape Cod, Massachusetts. Exposure experiments were conducted from August 29 to September 21, 2018 using groundwater from a relatively uncontaminated reference site and a fire training area contaminated site. To assess the uptake characteristics of the PFAS mixtures present in the 2 groundwater sources, 21-day mobile laboratory exposure experiments were conducted using fathead minnows (Pimephales promelas), polar organic chemical integrative samplers, and polyethylene tube samplers. Freshwater mussel (Ligumia subrostrata) exposure experiments were conducted for 14 days, beginning on day 7 of the fish and passive sampler exposures. Groundwater samples were collected daily (with a few exceptions). Samples for male fish and passive samplers were collected on days 0, 4, 7, 14, and 21. Samples for female fish were collected on days 0, 7, 14, and 21. The 14 day mussel exposures began on day 7 of the fish and passive sampler exposures, and mussel samples were collected on days 7, 11, 14, and 21. Groundwater site locations and well characteristics are presented in Table 1. Information on the various PFAS and co-occurring contaminants measured in the different media are presented in Table 2. Quality assurance results for PFAS analysis of the different media are presented in Table 3. Results for PFAS in groundwater are presented in Table 4. Results for co-occurring contaminants in groundwater are presented in Table 5. Results for fish biomarkers are presented in Table 6. Results for PFAS in male and female fish tissue are presented in Table 7. Results for PFAS in mussel tissue are presented in Table 8. Results for PFAS in polar organic chemical integrative samplers are presented in Table 9. Results for PFAS in polyethylene tube samplers are presented in Table 10.
