A key task during the performance of environmental human health risk assessments is the selection of appropriate chemical toxicity values. These values are combined with project-specific exposure estimates based on sampling or modeling to characterize the magnitude of health risks. The selection of toxicity values is a task repeated by every such risk assessment. Technical Guide 373 (TG373) is a new technical guide developed to set a standard approach to selecting toxicity values for use in Army environmental health risk assessments.
The TG373 Companion Dataset is generated using the TG373 method to give risk assessors a tool that can be used across all thier efforts. The TG373 supplements provide supporting information.
