Basic and applied research related to health and ecological effects of environmental contamination, including:

• health-based exposure criteria
  
  
• new, rapid, accurate, cost-effective technologies and methods to determine toxic effects in the environment.
  
  
• toxic substance fate and transport in the environment research.
  
  
• health-based replacement substance criteria reviews.

• Collaboration with other USACHPPM, Defense Department (DoD), Federal and State entities.

Wildlife Toxicity Assessments

WTAs address a primary wildlife and habitat risk evaluation component--subsequent and related toxicity associated with exposures to a specific chemical--through rigorous investigation and evaluation of toxicity data, and logical derivation of terrestrial wildlife Toxicity Reference Values.

Army Risk Assessment Modeling System (ARAMS). ARAMS integrates the following, individual, accessible units.

• Terrestrial Toxicity Database (TTD) An assemblage of chemical-specific soil screening levels (SSLs) and Toxicity Reference Values (TRVs) that assist in plant, invertebrate and wildlife risk identification.
  
  
• Terrestrial Wildlife Exposure Model (TWEM) a simple food web model useful in calculating oral exposures in various wildlife species.
  
  
• Life History Database(LHD)--contains relevant and vital information, such as ingestion rates, food types, home range and body weight range and population characteristics, to calculate exposure estimates for various wildlife species. A text version containing all the information within the database is available here.
  
  
• Bioaccumulation Factors Database(BAF) --An assemblage of refined chemical and biota-specific data that can be used to determine wildlife trophic transfer of contaminant concentrations in various food items.
  
  
• Spatially Explicit Exposure Model (SEEM) a selected wildlife species population-level model that estimates intake and risk as influenced by a determined area's relative habitat quality.
  
  
• Habitat Suitability Database(HSI)--integrates the U.S.Fish & Wildlife Service Habitat Suitability Indices into a user-friendly database format, that functions with SEEM.
