This document provides a screening level probabilistic acute dietary
exposure assessment for propylene chlorohydrin.  Propylene chlorohydrin
forms as a reaction product in commodities fumigated with propylene
oxide.  This assessment is an addendum to the Propylene Oxide Dietary
Exposure Assessment (B. Daiss, D329648, 6/30/06).  Background 

A screening level acute dietary risk assessment for propylene
chlorohydrin was conducted using the Dietary Exposure Evaluation Model
(DEEM-FCID(, Version 2.03) which uses food consumption data from the
USDA’s Continuing Surveys of Food Intakes by Individuals (CSFII) from
1994-1996 and 1998.  This assessment is considered highly conservative
based on the fact that a chronic endpoint was used in the absence of an
acute endpoint from the available toxicological data.  Data on levels of
the reaction product propylene chlorohydrin were provided in studies on
propylene oxide sterilization of nutmeats, cocoa powder, herbs and
spices, figs, prunes and raisins.  Residue distribution data from these
studies were used for the acute dietary analysis of propylene
chlorohydrin.  Percent crop treated data provided by the registrant and
verified by the Biological Economic Analysis Division were used for the
acute analyses where available.  Percent crop treated data was not
available for figs, prunes and raisins.  Therefore, 100% crop treated
was conservatively assumed for these commodities. The percent crop
treated values used for this assessment are the same as those used to
evaluate acute risk for propylene oxide.  For a more detailed
description of the methodology and input parameters used in this
assessment, please refer to the June 30, 2006 Propylene Oxide Dietary
Exposure Assessment conducted for the Propylene Oxide Reregistration
Eligibility Decision (D329648).

Toxicological Endpoint

An acute reference dose (RfD) was not established for propylene
chlorohydrin because an endpoint attributable to a single day exposure
was not identified from the available database.  Therefore, the chronic
RfD selected for propylene chlorohydrin from a two generation rat
reproduction study was used for the acute analysis.  This is an
extremely conservative endpoint for use in an acute assessment given
that the NOAEL is established from repeat dosing and is based on
decreased pup weights.  Doses and toxicological endpoints used for the
screening level acute dietary exposure scenarios are summarized in Table
1.

Acute Dietary Screening Analysis Exposure Results and Characterization

A probabilistic acute dietary exposure assessment was conducted for all
supported propylene oxide food uses for the general U.S. population and
various population subgroups for the propylene oxide reaction product
propylene chlorohydrin.  Since an acute RfD was not established for
propylene chlorohydrin because an endpoint attributable to a single day
exposure was not identified from the available database, the chronic RfD
was used.  Use of a chronic endpoint to assess acute dietary exposure
results in a highly conservative, screening level estimate of risk from
dietary exposure to propylene chlorohydrin that is likely to
significantly overestimate risks.  

 

The results of the DEEM acute dietary exposure analyses for propylene
chlorohydrin conducted using the chronic RfD as the toxicological
endpoint are reported in Table 2.  The DEEM acute dietary exposure
estimate for the highest exposed population subgroup, children 1-2 years
old, is 113% of the cPAD.   This assessment indicates that for all
supported commodities, the acute dietary exposure estimates for
propylene chlorohydrin are slightly above HED’s level of concern
(>100% PAD) for infants and young children.  However, given the highly
conservative nature of the assessment i.e., the use of a chronic
endpoint, use of 100% crop treated for some commodities, and use of
residue values at the earliest point of consumption, HED confidently
concludes that PCH does not present acute dietary risks of concern.
