PFASs proportions in water of different seasons were mutative in the Qing River.
Aquatic plants might have preference absorption for long-chain PFASs.
Absorption effect of roots and foliage of emergent plants were obviously different.
Capacity of tolerance and bioaccumulation towards PFOS of hornworts was good.
Hornworts could be used as remediation flora to eliminate PFOS pollution in water.
