This study investigated the accumulation and translocation characteristics of emerging short-chain per- and polyfluoroalkyl substances (PFAS) in a typical submerged macrophyte Aquarius uruguayensis through controlled exposure experiments. The target pollutants included six short-chain PFAS (three perfluoroalkyl carboxylic acids (PFCAs) and three perfluoroether acids (PFEAs)). A. uruguayensis demonstrated bioaccumulation capability of all six short-chain PFAS from water, with whole-plant bioconcentration factors (BCFtotal) ranging from 3.0 to 46.0L/kg, primarily detected in leaves with average shoot bioconcentration factors (BCFshoot) of 2.5~62.2L/kg; In addition to roots and stems, A. uruguayensis leaves were also proven capable of accumulating PFASs independently, with stronger absorption capacity than roots and stems; A. uruguayensis showed selective accumulation of the six short-chain PFAS, preferentially concentrating hydrophilic small-molecule PFASs, with plant BCF showing significant negative correlations with logKow and molecular mass(ρ1= -0.62, ρ2= -0.81, P<0.05), and its BCF decreases with the increase of logKow and molecular mass; Short-chain PFAS underwent translocation within the plant, with a high contribution from roots to leaves, and a low contribution from leaves to roots.
