  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 = _____________________ × 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.
