The northern cardinal (Cardinalis cardinalis) is a good indicator species for environmental contaminants because it does not migrate and its range covers a diversity of habitats, including metropolitan Atlanta, GA and the geographically isolated Hawaiian Islands. In addition, the cardinal is often found near people's homes, making it likely to be exposed to the same outdoor elements, including soil, groundwater, and air, that surrounding humans experience. In this study, blood serum concentrations of 12 per- and polyfluoroalkyl substances (PFASs) were measured in 40 cardinals from Atlanta and 17 cardinals from the Big Island (Hawaii), HI. We observed significantly higher median concentrations of four PFASs and significantly higher detection frequencies of seven PFASs in the cardinals from Atlanta, relative to the PFAS median concentrations and detection frequencies observed in the cardinals from Hawaii (α = 0.05). Among the PFASs measured, perfluorooctane sulfonate (PFOS) was observed in the highest concentrations. A linear regression model controlling for sex, age, and airport distance did not explain PFOS variation within the Atlanta samples, but a similar model explained 90% of PFOS variation within the Hawaii samples. To our knowledge, these are the first measurements of PFASs in northern cardinals.
北美红雀（Cardinalis cardinalis）是环境污染物的良好指示物种，因为它不会迁徙，其分布范围涵盖了多种栖息地，包括佐治亚州亚特兰大市和地理位置孤立的夏威夷群岛。此外，红雀通常出现在人们的家附近，因此很可能接触到与周围人类相同的户外元素，包括土壤、地下水和空气。在这项研究中，我们测量了来自亚特兰大的 40 只红雀和来自夏威夷大岛的 17 只红雀血清中 12 种全氟和多氟烷基物质（PFAS）的浓度。与来自夏威夷的红雀的 PFAS 中位数浓度和检测频率相比，我们观察到来自亚特兰大的红雀中有四种 PFAS 的中位数浓度显著更高，有七种 PFAS 的检测频率显著更高（α=0.05）。在所测量的 PFAS 中，全氟辛烷磺酸（PFOS）的浓度最高。一个控制性别、年龄和机场距离的线性回归模型并不能解释亚特兰大样本中 PFOS 的变化，但类似的模型可以解释夏威夷样本中 90%的 PFOS 变化。据我们所知，这是首次对北美红雀中的 PFAS 进行测量。
