The purpose of the Framework is to present key guiding principles based on the unique attributes of metals (as differentiated from organic and organometallic compounds) and to describe how these metals-specific attributes and principles may then be applied in the context of existing EPA risk assessment guidance and practices. This Framework document is not a prescriptive guide on how any particular type of assessment should be conducted within an EPA program or regional office. Rather, it outlines key metal principles and describes how they should be considered in conducting human health and ecological risk assessments to advance our understanding of metals impact and foster consistency across EPA programs and regions. As a result the Framework is a science-based document that describes basic principles that address the special attributes and behaviors of metals and metal compounds to be considered when assessing their human health and ecological risks. EPA’s Risk Assessment Forum oversaw the development of this document, which included input from stakeholders and experts throughout the Agency, obtained through several expert workshops, followed by peer review by the EPA Science Advisory Board. The Framework sets out a variety of principles that are general, fundamental properties of metals, which should be addressed and incorporated into all inorganic metals risk assessments. The five overarching principles are summarized as follows: (1) Metals are naturally occurring constituents in the environment and vary in concentrations across geographic regions; (2) All environmental media have naturally occurring mixtures of metals, and VerDate Aug<31>2005 18:53 Mar 07, 2007 Jkt 211001 metals are often introduced into the environment as mixtures; (3) Some metals are essential for maintaining proper health of humans, animals, plants and microorganisms; (4) Metals, as chemical elements, and unlike organic chemicals, are neither created nor destroyed by biological or chemical processes, although, these processes can transform metals from one species to another (valence states) and can convert them between inorganic and organic forms; and (5) The absorption, distribution, transformation and excretion of a metal within an organism depends on the metal, the form of the metal or metal compound, and the organism’s ability to regulate and/or store the metal.

Notice of Availability of the Framework for Metals Risk 
Assessment

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of document availability.

-----------------------------------------------------------------------

SUMMARY: The U.S. Environmental Protection Agency (EPA) is announcing 
the availability of the final ``Framework for Metals Risk Assessment'' 
(EPA 120/R-07/001, March 2007). The purpose of the Framework is to 
present key guiding principles based on the unique attributes of metals 
(as differentiated from organic and organometallic compounds) and to 
describe how these metals-specific attributes and principles may then 
be applied in the context of existing EPA risk assessment guidance and 
practices. This Framework document is not a prescriptive guide on how 
any particular type of assessment should be conducted within an EPA 
program or regional office. Rather, it outlines key metal principles 
and describes how they should be considered in conducting human health 
and ecological risk assessments to advance our understanding of metals 
impact and foster consistency across EPA programs and regions. As a 
result the Framework is a science-based document that describes basic 
principles that address the special attributes and behaviors of metals 
and metal compounds to be considered when assessing their human health 
and ecological risks. EPA's Risk Assessment Forum oversaw the 
development of this document, which included input from stakeholders 
and experts throughout the Agency, obtained through several expert 
workshops, followed by peer review by the EPA Science Advisory Board.
    The Framework sets out a variety of principles that are general, 
fundamental properties of metals, which should be addressed and 
incorporated into all inorganic metals risk assessments. The five 
overarching principles are summarized as follows: (1) Metals are 
naturally occurring constituents in the environment and vary in 
concentrations across geographic regions; (2) All environmental media 
have naturally occurring mixtures of metals, and metals are often 
introduced into the environment as mixtures; (3) Some metals are 
essential for maintaining proper health of humans, animals, plants and 
microorganisms; (4) Metals, as chemical elements, and unlike organic 
chemicals, are neither created nor destroyed by biological or chemical 
processes, although, these processes can transform metals from one 
species to another (valence states) and can convert them between 
inorganic and organic forms; and (5) The absorption, distribution, 
transformation and excretion of a metal within an organism depends on 
the metal, the form of the metal or metal compound, and the organism's 
ability to regulate and/or store the metal.
