Part 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.
