1. Suppose a 70-kg individual drinks 2 L/day of water containing 0.1 mg/L of 1,1-dichloroethylene for 20 years.
(a) Find the hazard quotient,( RQ) for this exposure.
(b) Find the cancer risk.
(c) If the individual drinks this water for 30 years instead of just 20, recompute the risk quotient and the cancer risk.
