EROD activity, chromosomal damage, and oxidative stress in response to contaminant exposure to tree swallows (Tachycineta bicolor) nesting in the Great Lakes Areas of Concern: Data Tree swallow, Tachycineta bicolor, nestlings were collected from 60 sites in the Great Lakes which included multiple sites at 27 Areas of Concern (AOCs) and 6 sites not listed as AOCs from 2010 to 2014. Nestlings were measured for ethoxyresorufin-O-dealkylase (EROD) activity, chromosomal damage (DNA CV), and six measures of oxidative stress. Each of these bioindicators was divided into four groups from the highest to lowest values and the groups were compared to contaminant concentrations using multivariate analysis. Nestling contaminant concentrations included polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), perfluorinated compounds (PFCs), and 17 elements. Alkylated polycyclic aromatic...

Tree swallow nestlings were collected from 69 sites which included multiple sites at some of the 27 Areas of Concern (AOCs) and at nine non-AOC sites. Polycyclic aromatic hydrocarbon (PAHs), polychlorinated biphenyl (PCBs), and polybrominated diphenyl ether (PBDEs) concentrations were measured in nestling stomach contents. Concentrations of PCBs and PBDEs were measured in nestling carcasses. Perfluorinated compounds (PFCs) were measured in nestling plasma. Pooled dietary concentrations of total PAHs were highest at the Rouge River, MI AOC (1,856 ng/g wet weight) and lowest at White Lake, MI...
