- Abstract
- Per- and polyfluoroalkyl substances (PFASs) are used in industrial and commercial products due to their amphiphilic
properties. Birds have been utilized as biomonitoring species due to their environmental pollutant vulnerability and
wide distribution. The Oriental Magpie (Pica serica) is a representative residential species inhabiting terrestrial
environments. In this study, we measured PFAS concentrations in Magpie liver tissue (n = 253) collected from
12 Korean regions in 2004 and 2017. The predominant compounds were perfluorooctanesulfonic acid (PFOS;
mean: 23.8 ng/g wet weight), perfluorotridecanoic acid (PFTrDA; 2.79 ng/g), and perfluoroundecanoic acid
(PFUnDA: 2.11 ng/g). We observed significant correlations between Magpie PFAS measurements, indicating similar
sources and bioaccumulation processes. Adult females showed significantly lower PFOS concentrations than adult
males and young males and females, indicating that avian sex is a crucial physiological factor of PFAS accumulation.
PFOS, perfluorodecanoic acid (PFDA), and perfluorotetradecanoic acid (PFTeDA) concentrations in urban regions
were significantly higher than rural regions. PFOS concentrations in Magpie livers increased significantly between
sampling years, whereas C11–C13 carboxylic acids (PFCAs) decreased. This suggests that urbanization and popula-
tion are major factors in Magpie PFAS accumulation. Almost all hepatic PFOS concentrations were below the thresh-
old values proposed by previous studies, implying limited risks. Our findings suggest that the Oriental Magpies are
PFAS sentinel in residential environments. This is the first comprehensive report on biomonitoring of PFASs using
the Oriental Magpie.
