APPENDIX B: CALCULATIONS

Calculations for Chemicals that do not cause cancer:

Comparison Value equals U.S. EPA RfD times Body Weight divided by the Intake Rate --and-- Exposure Dose equals Contaminant Concentration times the Intake Rate times the Exposure Factor divided by the Body Weight

Contaminant Concentration = the concentration of the chemical in water or soil.

Intake Rate = The amount of water or soil a person would drink or ingest.

Exposure Factor = The amount of time in years that a person would be exposed to the specific chemical. No exposure factor is used if the exposure occurs daily.

Body Weight = The amount a person weighs. Generally 70 kilograms is used for an adult and 10-15 kilograms for a child.

Calculation of risk for those chemicals that may cause cancer:

Comparison Value equals (Risk divided by the Oral Slope Factor) times the (Body Weight divided by the Intake Rate)

Lifetime Excess Cancer Risk = Annual exposure dose x slope factor x exposure factor in years

Dose is in mg/kg/day

Slope factor = The U.S.EPA cancer slope factor, (mg/kg/day)-1

Exposure factor = The amount of time in years that a person would be exposed to the specific chemical. No exposure factor is used if the exposure occurs over a person's lifetime.
