Human Health Risk
SADA provides a full human health risk assessment module and associated
databases. The risk models follow the EPA's Risk Assessment Guidance
for Superfund (RAGS) and can be customized to fit site specific exposure
conditions. The following landuse scenarios and exposure pathways are
available for both radionuclides and nonradionuclides to calculate risk
and data screening levels.
- Dermal contact
- External (radionuclides)
- Food consumption
- Combined Exposure
Risk results can be produced in standard tabular format or graphically.
This module allows users to perform benchmark screenings and the ability to calculate forward risk to a
number of terrestrial and aquatic receptors is currently being added. The routines access the contaminant
matching and data management functions already available in SADA. Accompanying the ecological risk module
is a database of benchmarks and other information that are supported and updated on the
SADA web site. Benchmarks are adjusted for
site-specific physical parameters
To set up ecological risk, the user goes through a simple
setup process that registers site
contaminants with toxicity and physical parameter information, as well as bringing information into the SADA file
that is necessary for exposure dose modeling.
Benchmark results can be produced in standard tabular format or graphically.
Terrestrial exposure dose models are also available in SADA.
Different types of output with terrestrial dose are available.
