Abstract : The overall objective of this research project was to explore the use of in situ biomonitoring using wild mammalian animal models to access ecotoxicity risks from petrochemical contaminants. We approached this objective by comparing the relative sensitivities of selected measures of metabolic, immunologic, genetic, and histopathologic toxicity (multiparameter model) in small mammalian residents of terrestrial ecosystems contaminated with complex mixtures of patrochemical (an abandoned oil refinery complex). Multiparameter response profiles of small mammals were evaluated relative to result from common laboratory bioassay tests (fathead minnow survival, rice seed germination test, etc.) and soil chemical analysis to determine their ability to predict ecotoxicity risk (as indexed by demographic changes in the small mammal community). pg1.
