Incremental Lifetime Cancer Risk (ILCR) Risk Calculation Tool

Use this tool to calculate the Incremental Lifetime Cancer Risk (ILCR) for a non-threshold contaminant (see training material for more information ).
If an Incremental Lifetime Cancer Risk greater than 1 x 10-5 is calculated, a cancer risk potentially exists.

Total Calculation of  Incremental Lifetime Cancer Risk:

ILCR = ((DoseSoilIngestion + DoseWaterIngestion + DoseFoodIngestion ) × SFOral) + ( DoseParticleInhalation × SFInhalation)+ (DoseDermalContact × SFDermal) =

SFOral = (kg day)/mg Oral slope factor for contaminant (see Table: Health Canada’s Slope Factors, or US EPA’s Slope Factors).
SFInhalation = (kg day)/mg Oral slope factor for contaminant (see Table: Health Canada’s Slope Factors, or US EPA’s Slope Factors).
SFDermal = (kg day)/mg Dermal slope factor for contaminant (see Table: Health Canada’s Slope Factors, or US EPA’s Slope Factors). Where SFDermal is not available, use the SFOral value.
DoseSoilIngestion = mg/(kg day)
DoseWaterIngestion = mg/(kg day)
DoseFoodIngestion = mg/(kg day)
DoseParticleInhalation = mg/(kg day)
DoseDermalContact = mg/(kg day)
Total Dose =   mg/(kg day)
