A 70 kg adult male is exposed to cadmium-containing vapors at his worksite. If he inhales 20m3 per work day and he works 8 hours a day, 5 days a week, 48 weeks a year, for 30 years, what is the maximum allowable cadmium concentration in the air if the cancer risk is to be maintained below 10−6? How would the acceptable concentration change if the calculation were repeated for a 50 kg woman?

A laboratory trial is conducted to evaluate the risks associated with consumption of pesticide-contaminated water. 45 out of 500 mice exposed to the pesticide-contaminated water develop stomach cancer. 11 out of 500 mice that were not exposed to the pesticide contaminated water also developed cancer. What are:
- a. the relative risk?
- b. the attributable risk?
- c. the odds ratio?
