AB  - Shorebirds (order Charadriiformes) are among the world's most threatened avian 
      taxa. Within the East Asian-Australasian Flyway (EAAF), a major threat to 
      shorebirds' survival may be the gauntlet of pollution along the flyway. Metals, 
      persistent organic pollutants (POPs), and per-/polyfluoroalkyl substances (PFASs) 
      persist in the environment to the detriment of wildlife. In this study, we 
      analysed element and PFAS concentrations in blood from 142 individuals across six 
      species of Arctic-breeding migratory shorebirds with contrasting population 
      trends, to discern species- and site-specific pollution differences, and 
      determine how pollution correlated with population trends of EAAF shorebirds. 
      Potential within-year pollution variations were investigated by blood-sampling 
      birds at two sites, representing different points in the birds' annual 
      migrations: staging in Taiwan on southward migrations and at non-breeding grounds 
      in Western Australia (WA). Species' pollutant concentrations were compared to 
      established population trends. Concentrations of potentially toxic elements were 
      low in most individuals regardless of species. PFASs (range: <0.001-141 ng/g), Hg 
      (<0.001-9910 ng/g) and Pb (<0.01-1210 ng/g) were higher in Taiwan than in WA 
      (PFAS Taiwan median: 14.5 ng/g, WA median: 3.45 ng/g; Hg Taiwan: 338 ng/g, WA: 
      23.4 ng/g; Pb Taiwan: 36.8 ng/g, WA: 2.26 ng/g). Meanwhile As (range 
      <0.001-8840 ng/g) and Se (290-47600 ng/g) were higher in WA than Taiwan (As 
      Taiwan median: 500 ng/g, WA median: 1660 ng/g; Se Taiwan: 5490 ng/g, Se WA: 
      23700 ng/g). Nevertheless, pollutant concentrations in a subset of individuals 
      may exceed sublethal effect thresholds (As, Se and PFASs). Finally, we found no 
      consistent differences in pollution among species and demonstrated no correlation 
      between pollution and population trends, suggesting pollution is likely not a 
      major driver for population declines of EAAF shorebirds. However, ongoing and 
      locally heavy environmental degradation and exposure to other contaminants not 
      investigated here, such as POPs, warrants continued consideration when managing 
      EAAF shorebird populations.
