I he content of 13 analogues of PFAS—PFHpA (perfluoroheptanoic acid). PFOA (perfluorooctanoic acid). PFNA (perfluorononanoic acid). PFDA (perfluorodecanoic acid). PFUnA (perfluoroundecanoic acid). PFDoA (perfluorododecanoic acid). PFIrA (perfluorotridecanoic acid). PFIeA (perfluorotetradecanoic acid). PFHxS (perfluorohexane sulfonate). PFHpS (perfluoroheptane sulfonate). PFOS (perfluorooctane sulfonate). and PFDS (perfluorodecane sulfonate). PFHxA (perfluorohexanoic acid). was examined. For quantitation prior to an extraction procedure mass labelled internal standards were added into freeze-dried fish samples. I he samples were extracted with ammonium acetate in methanol. and centrifuged. I he supernatants were collected. extracts were evaporated to dryness and filtered Ihe PFAS were analysed using liquid chromatography negative ion electrospray tandem mass spectrometry (LCESI-MS/MS). Details of the LC-ESI-MS/MS parameters and quantitation have been presented earlier (Koponen et al. 2013). Measurement uncertainty of PFAS was 30%.
Perfluorodecanoic Acid (PFDA)

Perfluorodecanoic acid (PFDA, or sometimes PFDeA or Ndfda) is classified as a perfluorinated carboxylic acid and is used in commercial wetting agents and aqueous film forming foams (AFFF). It has been found in environmental samples contaminated by AFFF use, and in human maternal and cord serum samples collected at delivery (Yang et al. 2016). The half-life of PFDA in laboratory animals and humans is unknown. There is very little toxicity information published for PFDA, although a few publications are valuable in the assessment of its potential to affect development and endocrine function (Harris and Birnbaum 1989, Van Rafelghem et al. (1987). Toxicity information of PFDA is limited to the class Mammalia.
Variabilities in concentrations of selected perfluoroalkyl acids among normotensives and hypertensives across various stages of glomerular function
Published in Archives of Environmental & Occupational Health, 2021
Relevant data on demographics, body measures, PFAA, serum creatinine, diabetes, anemia, and albuminuria were downloaded from NHANES for 2003-2016 for US adults aged > = 20 years. PFAA selected for analyses for this study were PFOA, PFOS, perfluorodecanoic acid (PFDA), perfluorohexane sulfonic acid (PFHxS), and perfluorononanoic acid (PFNA) because these were the only PFAAs for which at least 60% values were observed to be at or above the limit of detection (LOD). Percent observations > = LOD were found to be 99.7%, 99.9%, 74.8%, 98.5%, and 99.1% for PFOA, PFOS, PFDA, PFHxS, and PFNA respectively.
