Universal Citation: MN Rules 4717.8450
Current through Register Vol. 48, No. 39, March 25, 2024
Subpart 1. Scope.
This part establishes the methods for determining the multimedia health risk values (MHRVs) for carcinogens emitted to the air.
Subp. 2. General equation for calculating MHRVs for carcinogens.
The general equation for calculating MHRVs for carcinogens is:
Additional lifetime risk | ||
MHRV = | -------------------------------- | X 1,000 |
Potency slope |
Where:
A. MHRV is
expressed in units of micrograms per kilogram of body weight per day (
µg/kg-day);
B. potency slope is
expressed in units of the inverse of milligrams per kilogram of body weight per
day (mg/kg-day)-1;
C. additional lifetime risk is unitless;
and
D. 1,000 is a factor to convert
milligrams to micrograms.
