Abstract : This project was developed to improve direct testing and refinement of the use of spatial models for wildlife exposure assessments. Past studies focused on whether spatial models could improve the assessment of avian exposures to chemicals in the environment. This study examined the value of spatial models with respect to improving the assessment of small mammal exposures in the environment, and aimed to overcome the disconnect that exists when applying spatial considerations between site-wide averages and an assessment that captures exposures based on species-specific habitat preferences.
