Draft Toxicological Review of Acrylamide: In Support of Summary 
Information on the Integrated Risk Information System (IRIS)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of Public Comment Period.

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

SUMMARY: The EPA is announcing a public comment period to review the 
final draft document titled, ``Toxicological Review of Acrylamide: In 
Support of Summary Information on the Integrated Risk Information 
System (IRIS)'' (EPA/635/R-07/009), related to the human health 
assessment for acrylamide. The document was prepared by the National 
Center for Environmental Assessment (NCEA) within EPA's Office of 
Research and Development.
    EPA is releasing this draft document solely for the purpose of pre-
dissemination peer review under applicable information quality 
guidelines. This document has not been formally disseminated by EPA. It 
does not represent and should not be construed to represent any Agency 
policy or determination. EPA will consider any public comments 
submitted in accordance with this notice when revising the document.

DATES: The 60-day public comment period begins on December 28, 2007 and 
ends February 26, 2008. Technical comments should be in writing and 
must be received by EPA by February 26, 2008.

ADDRESSES: The draft ``Draft Toxicological Review of Acrylamide: In 
Support of Summary Information on the Integrated Risk Information 
System (IRIS)'' (EPA/635/R-07/009) is available primarily via the 
Internet on NCEA's home page under the Recent Additions menu at

SUPPLEMENTARY INFORMATION: 

I. Information About the Document

    Acrylamide is a monomer used primarily in the production of 
polyacrylamide polymers. Polyacrylamides are used as a flocculent in 
water purification, oil recovery, and soil stabilization; and in the 
manufacturing of a wide range of products as a coating, matrix, 
additive, or stabilizer. Human exposure to acrylamide occurs primarily 
in the workplace from dermal contact and inhalation of dust and vapor 
during processing or use. The public may be exposed to acrylamide 
through emissions from production facilities, use in consumer products, 
contaminated drinking water, and cigarette smoke. In early 2002, 
Swedish scientists reported high concentrations of acrylamide in 
certain fried, baked, and deep-fried foods. Subsequent research 
demonstrated that acrylamide forms ``de novo'' (i.e., newly formed, not 
present as an environmental contaminant) during high temperature 
cooking of carbohydrate-rich foods that contain asparagine and in a few 
other food processes. Considerable research is on-going to assess the 
level of and the potential risk from exposure to

[[Page 73814]]

acrylamide in food (additional information is available on the U.S. 
FDA's Internet site for acrylamide: http://www.cfsan.fda.gov/lrd/pestadd.html#acrylamide
).

    This public review draft of ``Toxicological Review of Acrylamide'' 
is an update and reassessment of the human health effects that may 
result from exposure to acrylamide. The acrylamide oral and inhalation 
reference values and carcinogenicity classification have been revised 
based upon new data and changes in guidance that have occurred since 
the previous assessment in 1988.
    IRIS is a database of human health effects that may result from 
exposure to various chemical substances found in the environment. The 
database (available on the Internet at http://www.epa.gov/iris) 

contains qualitative and quantitative health effects information for 
more than 540 chemical substances that may be used to support the first 
two steps (hazard identification and dose response evaluation) of the 
risk assessment process. When supported by available data, the database 
provides oral reference doses (RfDs) and inhalation reference 
concentrations (RfCs) for health effects, and oral slope factors and 
inhalation unit risks for carcinogenic effects. Combined with specific 
exposure information, government and private entities use IRIS to help 
characterize public health risks of chemical substances in a site-
specific situation and thereby support risk management decisions 
designed to protect public health.
