Breeding songbird tissue analysis and metal concentrations in tissues, soil and invertebrates collected near nesting sites within the Southeast Missouri Lead Mining District, 2016-19

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.

Histopathology of American Kestrels (Falco sparverius) Exposed to Two Brodifacoum Isomer Formulations with Differing Elimination Half-Lives

This dataset documents histopathological changes in liver, kidney, skeletal muscle and intestine of captive American kestrels (Falco sparverius) exposed to brodifacoum formulations with differing elimination half-lives in target rodents. The toxicity of two brodifacoum formulations with stereoisomers having markedly different elimination half-lives in rats (Formulation A containing the 2 least persistent stereoisomers, Formulation B containing the most persistent stereoisomer) were tested in a 7-day dietary feeding trial. Based on previous kestrel studies using commercially available brodifacoum, Formulations A and B were each provided at 3 dietary concentrations (0.05, 0.1 and 0.5 µg/g diet, 4 kestrels/dose level)...
