Table 6: Concentration of 18 PFAS in unknown fish samples ■ Conclusion

Large Farm raised A novel supercritical fluid extraction method, using
Walleye Mouth Trout the Shimadzu Nexera UC offline SFE system, for the
ng/g
Bass ng/g ng/g extraction of PFAS compounds from fish tissue was
PFBS 1.0 1.6 n.d. evaluated and provided excellent results for recovery,
PFHxA n.d. n.d. n.d. linearity, and reproducibility. The results summarized
HFPO-DA n.d. n.d. n.d. here demonstrate the suitability of SFE as a sample
