This dataset provides results for the following: (1) metals concentrations in soils surrounding breeding song bird nest sites; (2) metals concentrations in invertebrates (earthworm and grub composites) collected near nest sites; (3) metals concentrations and delta-aminolevulinic acid dehydratase (ALAD) activity in avian blood samples; and (4) metals concentrations, indicators of oxidative stress and DNA damage, and histopathology in liver and/or kidney tissues collected from breeding song birds.

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...
