Abstract

This study investigated the concentrations of 45 per‐ and polyfluoroalkyl substances (PFASs) in fledgling Flesh‐footed Shearwater (Ardenna carneipes; n = 33) and Wedge‐tailed Shearwater (A. pacifica; n = 9) livers via LC‐MS/MS and their relationship to body morphometrics and ingested plastic mass recorded in 2019 on Lord Howe Island, NSW, Australia. Sixteen PFASs were detected, of which perfluorooctanesulfonate (PFOS) was the dominant compound, detected in 100% of birds (1.34 to 13.4 ng/g ww). Long‐chain perfluorocarboxylic acids, including perfluorodecanoic acid (PFDA; 50% of birds. There was a positive correlation between PFDA and PFTrDA concentrations and wing chord length (Rs=0.36, p=0.0204; Rs=0.44, p=0.0037 respectively), and between PFDA concentrations and total body mass (Rs=0.33, p=0.032) suggesting that these compounds may impact shearwater fledgling morphometrics. Plastic was present in the intestinal tract of 79% of individuals (
