Minn. R. agency 144, ch. 4717, HEALTH RISK VALUES, pt. 4717.8450 - EQUATION FOR CALCULATION OF MHRV FOR CARCINOGENS
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.
