In some lakes, the fish are contaminated with methylmercury. As a member of the Department of Environmental Quality, you have been assigned the job of developing an "advisory" for adult males to limit consumption of fish from these lakes. The advisory will be in terms of a recommended limit on the number of fish meals per unit of time. You must determine the unit of time, which is one per day, or one per week, or one per month. In addition to the EPA recommended values for estimating intake, use 1 x 10-6 for the fraction ingested, a 30-year exposure duration, and a 30-year averaging time to estimate the chronic daily intake. Your superiors have set a hazard index of 0.10 as a matter of policy. The RfD for methylmercury is 1 x 10-4 mg/kg-day.
