The goal of this study was to evaluate human exposure to per- and polyfluoroalkyl substances (PFASs) in the air near the Hyeongsan River in Pohang, and to quantify associated health risks. The daily intake of PFOS was the highest, and those of PFBS, PFHxA, PFUnDA, and PFOA were also high. Humans were exposed more to ionic PFASs than to neutral PFASs. The exposure level of PFASs increased from upstream to downstream; this trend suggests that emission sources exist downstream. For the gaseous phase, the exposure level was highest to PFBS, which have the shortest carbon-chain length, whereas for the particulate phase, exposure was highest to PFOS. The exposure and distribution of PFAS congeners differed among sites and phases, which means that humans are exposed differently depending on the PFASs emitted from the emission source at each site, and on the physicochemical properties of PFASs. Inhalation exposure to PFASs was below the PFAS intake safety threshold, and the toxicity was also lower than the level allowed by WHO. However, health risks from long-term exposure to PFASs are of concern, and combining exposure by various routes may have a significant health effect. Therefore, continuous monitoring and risk assessment are required.

Per-and polyfluoroalkyl substances (PFAS) are synthetic chemicals that exhibit various physicochemical characteristics, making it difficult to analyze many PFAS simultaneously. In this study, the simultaneous analytical methods of 37 per- and polyfluoroalkyl substances (PFAS), including the PFAS alternative compounds Gen-X, ADONA, Major F53B, Minor F53B, and precursors FOSA, FOSAA, MeFOSAA, EtFOSAA, n:2 FTUA, n:3 FTCA, and n:2 FTS in drinking water and sediment samples were developed using liquid chromatography-tandem mass spectrometry based on the Korean persistent organic pollutants (POPs) standard method. The water samples were extracted using a WAX cartridge by solid-phase extraction, while the sediment samples were extracted by ultrasonic extraction. The accuracy and precision satisfied the values of 50.7-118% and 0.01-8.5%, respectively, with a method detection limit of 0.12-1.36 ng/L. The PFAS analytical method for sediment samples was modified based on the Korean standard analytical method for persistent organic pollutants. The accuracy and precision of the 37 target PFAS ranged from 63% to 129% and 0.6% to 11.7%, respectively, with method detection limits of 0.03-1.94 ng/g in sediment. Satisfactory results were obtained for water samples using the current Korean standard analytical method for POPs. Meanwhile, for sediment samples, owing to the poor results obtained for the two compounds, the method was modified.

Cylindrospermopsin (CYN) is an emerging freshwater cyanobacterial toxin, and its reports on toxicity toward the human liver and kidney tissues has drawn a lot of attention. An appropriate analytical method is necessary to determine the presence of this emerging cyanobacterial toxin in water resources including drinking water; therefore, it is necessary to develop a sensitive analytical method for CYN detection. In this study, we developed a simple and sensitive analytical method for CYN detection using liquid chromatography-tandem mass spectrometry (LC-MS/MS) using direct injection. The method was validated for linearity of calibration, limit of detection, limit of quantitation, accuracy, and precision. The limit of detection and quantitation were in the range of 0.029 μg/L and 0.091 μg/L, respectively. Accuracy and precision were also obtained within an acceptable range. The optimized method was used to measure the concentrations of CYN in the surface water from each weir areas of the Geum River, Nakdong River. Additionally, this method was applied to samples of drinking water obtained from the treatment plants of the Geum River, Nakdong River for each process.
