The fda recommends that women who are pregnant avoid eating more than three 6.00 oz servings of bluefish per month because of the relatively high mercury levels in that type of fish. if bluefish contains 0.321 ppm of mercury (that is, 0.321 oz of mercury per 1×106 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?

Tooth enamel consists mainly of the mineral calcium hydroxyapatite, ca_10(po_4)_6(oh)_2. trace elements in teeth of archaeological specimens provide anthropologist with clues about diet and diseases of ancient people. students at hamline university measured strontium in enamel from extracted wisdom teeth by atomic absorption spectroscopy. solutions with a constant total volume of 10.0 ml contained 0.726 mg of dissolved tooth enamel plus variable concentrations of added sr. added sr find the concentration of sr in the 10 ml sample solution in parts per billion = ng/ml. find the concentration of sr in tooth enamel in parts per million = mu g/g.
