Seventeen PFAS compounds were detected at least once in liver samples, with PFOS found in 100 % of liver samples, and PFDA and PFBA detected in over 50 % of liver samples. The seven PFAS found in liver samples above 1 ng/g (and their maximum concentrations) were PFOS (96.0 ng/g), 6:2 FTS (48.4 ng/g), PFBA (9.14 ng/g), NFDHA (5.75 ng/g), PFOA (4.84 ng/g), PFHxS (2.78 ng/g), and PFHpA (2.42 ng/g). Statistically significant differences in PFAS concentrations were found between sites; PFAS profiles were generally consistent with the known or suspected PFAS sources at the three sites. Total PFAS concentrations also differed between deer life stage-sex groups, with adult males having significantly higher concentrations of total PFAS compared to adult females and male fawns. To assess human consumption potential, paired deer muscle samples were evaluated when liver PFOS reached a concentration threshold of ≥20 ng/g (<em>n</em> = 17 muscle samples). PFOS was the most frequently detected PFAS in muscle (88 % detection frequency), with PFOS liver levels approximately two orders of magnitude higher than in the paired muscle tissue.

Using a Bruker timsTOF Pro 2 instrument, three fat-based proficiency test samples - fish oil, palm oil, and milk fat - were analyzed and compared to a validated GC-sectorHRMS method, in accordance with the criteria set by Commission Regulation (EU) 2017/644. Linearity was confirmed across broad dynamic ranges, with relative response factor (RRF) precision consistently below 20 %. Instrumental limits of quantification (iLOQs) reached the 100–500 fg/μL range for dioxins and low pg/μL for PCBs, while method LOQs (mLOQs) were typically in the high fg/g to low pg/g range. Intermediate precision (RSD<sub>R</sub>) remained below regulatory thresholds in 97 % of cases. Furthermore, 80 % of PCDD/Fs and over 87 % of PCB measurements met trueness requirements, with summed WHO<sub>2005</sub>-TEQ and NDL-PCB concentrations in close agreement with sectorHRMS values. Importantly, the addition of the ion mobility dimension provided distinct benefits. It enabled the separation of coeluting isomers (e.g., 2,3,7,8-TCDD), resolved isobaric interferences (e.g., PeCDD and HxCB 169), and allowed for high-confidence analyte identification using collision cross section (CCS) values. CCS differences between native and <sup>13</sup>C-labeled standards were consistently below 0.5 %, supporting its use as an additional identification criterion.
