Oxidative stress biomarkers indicate sublethal health effects in a sentinel small mammal species, the deer mouse (Peromyscus maniculatus), on reclaimed oil sands areas

- Biomarkers of oxidative stress evident in deer mice on reclaimed, oil sands mine.
- Liver and testes GSH redox and Vit A status indicate disruption in oil sands mice.
- Selected biomarkers respond to higher tissue Co, Se, and Tl from oil sands site.
- Oxidative stress parallels decreased body condition and testis mass in deer mice.
- Biomarkers in mice are specified to support risk assessments in oil sands region.
