If bluefish contains 0.336 ppm of mercury (that is, 0.336 oz of mercury per 1 × 10 6 oz of fish), how many ounces of mercury would a pregnant woman consume in a month if she ate the maximum recommended amount of bluefish?
The recommended amount of blue fish in pregnant women is 0.5 pounds once a month. So, 0.5 pound is solely 8 ounces. If 0.336 oz of mercury is present in 1 x 10^6 oz of fish then (8 / 1000000) x 0.366 = 2.688 x 10^-6 oz is the amount of mercury a pregnant woman will consume if she eats half a pound of blue fish one per month.
