We 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 liquid chromatography–tandem mass spectrometry 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 (1.34–13.4 ng/g wet wt). Long‐chain perfluorocarboxylic acids, including perfluorodecanoic acid (PFDA; <0.04–0.79 ng/g wet wt) and perfluorotridecanoic acid (PFTrDA; <0.05–1.6 ng/g wet wt) were detected in >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 (<7.6 g), although there was no correlation between PFAS concentrations and plastic mass, indicating that ingested plastic is not the likely primary exposure source. The widespread occurrence of PFASs in fledgling marine birds from a relatively pristine location in the Southern Hemisphere suggests that further studies in adult shearwaters and other marine birds are warranted to investigate whether there are any long‐term physiological effects on bird species.

受太平洋偏远岛屿塑料消耗影响的雏海鸥的全氟和多氟烷基物质与身体形态测量学之间的相关性

我们调查了 45 种全氟烷基物质和多氟烷基物质 (PFAS) 在新生肉足剪切水(Ardenna carneipesn  = 33)和楔尾剪切水(A. pacifican)中的浓度 = 9) 2019 年在豪勋爵岛(澳大利亚新南威尔士州)记录的通过液相色谱-串联质谱法测定的肝脏及其与身体形态计量学和摄入的塑料质量的关系。检测到 16 种 PFAS,其中全氟辛烷磺酸 (PFOS) 是主要化合物,在 100% 的鸟类中检测到(1.34–13.4 ng/g 湿重)。在超过 50% 的鸟类中检测到长链全氟羧酸,包括全氟癸酸(PFDA;<0.04–0.79 ng/g 湿重)和全氟十三酸(PFTrDA;<0.05–1.6 ng/g 湿重)。PFDA 和 PFTrDA 浓度与翼弦长度呈正相关(R s  = 0.36,p  = 0.0204;R s  = 0.44,p = 0.0037,分别),以及 PFDA 浓度和总体质量之间(R s  = 0.33,p  = 0.032),表明这些化合物可能会影响剪切水雏形形态测量学。尽管 PFAS 浓度与塑料质量之间没有相关性,但 79% 的个体(<7.6 克)的肠道中存在塑料,这表明摄入的塑料不是可能的主要暴露源。全氟和多氟烷基物质在南半球相对原始位置的雏海鸟中广泛存在,这表明有必要对成年海鸥和其他海鸟进行进一步研究,以调查是否对鸟类物种有任何长期的生理影响。环境毒理学化学2021;40:799-810。© 2020 SETAC
