Zusammenfassung:[SUMMARY][OBJECT] To provide a per- and polyfluoroalkyl compound-adsorbing activated carbon having a high collection rate of per- and polyfluoroalkyl compounds in an atmospheric sample, and a filter body using the same.[ACHIEVING MEANS] A per- and polyfluoroalkyl compound-adsorbing activated carbon for desorbably adsorbing per- and polyfluoroalkyl compounds in an atmospheric sample, the activated carbon including an activated carbon adsorbent having a BET specific surface area of 900 m2/g or more, a sum (Vmic) of a volume of micropores of 1 nm or less of 0.35 cm3/g or more, a sum (Vmet) of a volume of mesopores of 2 to 60 nm of 0.02 cm3/g or more, a volume difference (Vs) between the micropore volume (Vmic) and the mesopore volume (Vmet) of 0.45 or more, and a surface oxide amount of 0.10 meq/g or more.
