Wildlife Toxicity Reference Values (TRVs)
for Ecological Risk Assessments
An integral component of a wildlife ecological risk assessment (ERA) is the development of some quantitative measure of the toxicity of a chemical to the animals of concern. This measure is often referred to as a toxicity reference value, or TRV. Our Center has developed, and is implementing, a standard method for developing toxicological profiles and toxicity reference values for military-related substances that may potentially pose risks to wildlife. Our Technical Guide 254 provides the standard practice for the development and documentation of wildlife TRVs. It is written primarily for risk assessors. The Standard Practice can be downloaded by clicking on the icon below.

Our Center's Wildlife Toxicity Assessment (WTA) program is implementing this Standard Practice for environmental chemicals of military concern. The Standard Practice is primarily intended for use by this Center to generate wildlife TRVs that are defensible and to provide a standard set of information for practitioners in the field. If a TRV relevant to a particular Army ERA has been generated by this Center using this methodology, then its use is expected unless an alternative can be reasonably defended. This Center is implementing this program in a phased approach, focusing upon the highest priority chemicals first. Other U.S. Army and military entities are encouraged to use this Standard Practice and our WTA reports within their ERA programs.

The Army Surgeon General is responsible for providing policy and technical expertise on human health and ecological aspects of pollution resulting from Army activities and operations (Army Regulation (AR) 200-1 Environmental Protection and Enhancement and AR 40-5 Preventive Medicine). The Army Surgeon General has delegated this responsibility through the U.S. Army Medical Command to the U.S. Army Center for Health Promotion and Preventive Medicine. This guide was developed pursuant to this authority.
This technical guide and the associated wildlife toxicity assessment reports should not be construed as official Department of the Army policy unless so designated by other authorizing documents. This document provides guidance and technical reference material based on scientific information current at the time of publication. As available information and supporting data are continuously being advanced, users are cautioned to ascertain existence of any updated information.
