Determination and partitioning behavior of perfluoroalkyl carboxylic acids and perfluorooctanesulfonate in water and sediment from Dianchi Lake, China

► A method for determination of ten PFCs in water and sediment was developed. ► Occurrence and partitioning of PFCs between water and sediment was evaluated. ► Values of logKoc were correlated with PFCA alkyl chain length.
