Raw leachates from three landfills and treated leachates from two landfills on Jeju Isalnd were analyzed for ten perfluorinated compounds (PFCs) detected in aquaruc environments. The leachates were collected six times in 2014 and 2015. Among the ten PFCs, three were not detected, namely perfluoroundecanoic acid (PFUnDA), perfluorododecanoic acid (PFDoDA), and perfluorodecane sulfonate (PFDS). The total concentrations of PFCs ranged as 724-3313 ng/L (mean 1999 ng/L) in raw leachates and from less than the limit of quantification (LOQ) to 394 ng/L (mean 133.2 ng/L) in treated leachates. The domonant compounds measured were perfluorooctanoic acid (PFOA) (mean contribution 37.7%) and perfluorobutane sulfonate (PFBS) (mean contribution 38.2%) in raw leachates, and PFOA (mean contribution 40.7%), perfluorohexanoic acid (PFHxA) (mean contribution 27.3%) and PFBS (mean contribution 26.5%) in treated leachates. No significant correlations were observed between total/several individual PFCs and leachate pH and CODCr, which may be due to complex chemical nature of landfill leachates and characteristics of waste and landfills.
