Calculations for Chemicals that do not cause cancer:
Noncancer Comparison Value = U.S.EPA Reference Dose x Body Weight
____________________________________
Intake Rate
Body Weight = The amount a person weights. Generally 70 kilograms is used for an adult and 10-15 kilograms for a child.
Intake Rate = The amount of water or soil a person would drink or eat.
Cancer Risk Guide
Cancer Risk Guide = Body Weight x Risk Factor
____________________________
Intake Rate x Cancer Slope Factor
Body Weight = The amount a person weights. Generally 70 kilograms is used
for an adult body weight.
Risk Factor = Either one additional cancer in one person in 10,000 people, one person in 100,000 people or one person in 1,000,000 people.
Intake Rate = The amount of water or soil a person would drink or eat.
Cancer Slope Factor = It is a U.S.EPA number which represents the cancer potential of a chemical. Each chemical has its own slope factor.
