“…In brief, water samples were taken near under the surface water using 2-L plastic bottle made of polypropylene (PP) mounted on a tall pole and then transported and stored in 500 mL PP bottles. Substantial losses of organofluorines could potentially be associated with sampling and storing of samples in PP tubes [ 36 , 37 ], which potentially led to an underestimation of EOF and PFAS target values. Samples were collected in triplicates from each sampling point.…”

Per- and polyfluoroalkyl substances (PFAS) are emerging organic pollutants and can occur in surface and groundwater. To identify the degree of pollution in surface water with PFAS, often targeted HPLC–ESI–MS/MS has been employed in which commonly 30–40 compounds are analyzed. However, other PFAS and organofluorines remain undetected. We sampled surface water of the river Spree and the Teltow Canal in Berlin, Germany, which are affected by the effluent discharge of wastewater treatment plants. Here, we employed high-resolution continuum source graphite furnace molecular absorption spectrometry (HR-CS-GFMAS) for measuring extractable organofluorines (EOF) and compared in a mass balance approach the total fluorine to the identified and quantified PFAS from the targeted analysis. The analysis highlights that the EOF are in the range expected for an urban river system (Winchell et al. in Sci Total Environ 774, 2021). However, downstream of an effluent discharge, the EOF increased by one order of magnitude, e.g., 40.3 to 574 ng F L−1, along the Teltow Canal. From our target analytes, mostly short-chained perfluorinated carboxylic acids and sulfonates occur in the water, which however makes up less than 10% of the EOF. The increase in EOF in the Teltow Canal correlates well with the increase of perfluorohexanoic acid (PFHxA), indicating that PFHxA is characteristic for the discharged EOF but not responsible for the increase. Hence, it points to PFHxA precursor discharge. The study highlights that EOF screening using HR-CS-GFMAS is necessary to identify the full scale of pollution with regard to PFAS and other organofluorines such as pharmaceutical compounds from the effluent of WWTPs.

“…We note that some of these samples were not collected specifically for this study and that, consequently, sample bottle material, storage duration, and storage temperature are variable among the sample types. Nevertheless, we do not expect this to impact our analysis because previous studies have shown that sample bottle material, storage duration, and storage temperature do not significantly impact the recovery of short- and ultrashort-chain PFCAs and PFSAs. , We used 12 mL polypropylene syringes and 0.45 μm cellulose acetate membrane syringe filters (Restek) to filter 10 mL aliquots of each sample into polypropylene beakers. We serially diluted each sample up to 1 000 000-fold with Milli-Q water to create a series of prepared samples with varying target PFAS concentrations to ensure that the acquired data were within the range of our calibration curve.…”

Per-and polyfluoroalkyl substances (PFASs) are a class of chemicals of growing concern. Recently, there has been a shift toward the use of short-and ultrashort-chain PFASs, which are difficult to measure with current analytical methods and rarely included in environment monitoring studies. In this research, we developed and optimized online solid-phase extraction, highperformance liquid chromatography, and electrospray ionization high-resolution mass spectrometry methods for the rapid and simultaneous quantification of 10 short-and ultrashort-chain PFASs. We applied our method to water samples collected from a variety of natural, engineered, industrial, and commercial water systems. We detected ultrashort-chain PFASs in every sample, including hydraulic fracturing water and wastewater samples and wastewater from electronic fabrication facilities for the first time, identifying previously unknown sources of ultrashort-chain PFASs. We also measured ultrashort-chain PFASs in a variety of drinking water sources, including what was thought to be pristine groundwater and surface water sources. The measurement of ultrashortchain PFASs in every sample type studied here raises concern over the potential ubiquity of these compounds in the environment and highlights the need for further monitoring studies, especially as longer-chain PFASs become regulated, and the industrial shift to short-and ultrashort-chain PFASs increases.

Tracking PFAS in Drinking Water: A Review of Analytical Methods and Worldwide Occurrence Trends in Tap Water and Bottled Water

et al. 2023

View full text Add to dashboard Cite

Per-and polyfluoroalkyl substances (PFAS) used in various industrial applications are pollutants of concern for the environment and human health. Drinking water consumption is one key exposure pathway to PFAS, as recently highlighted by multiple studies on their occurrence in tap and bottled water worldwide. However, PFAS quantification at low part-pertrillion (ng/L) or part-per-quadrillion (pg/L) concentrations remains challenging. PFAS presence in blanks and incomplete method recoveries can lead to false positives or negatives; PFAS concentration changes under different storage durations or conditions can also affect accuracy and precision. Here, we review the most recent data related to analytical methods that were used in research articles for the detection and quantification of PFAS from drinking water. Commonly encountered pitfalls are summarized, and analytical performance is appraised including detection limits, recovery, matrix effects, and other quality assurance/quality control endpoints. In addition, we collated available guidelines for health advisory levels of PFAS in tap water. Finally, we compiled concentration data on legacy and emerging PFAS in tap and bottled water.
