Unformatted text preview: 1 1 30 1 1 30 = d Cd g d food kg food kg Cd g Final answer: Total Cd intake is 34 g Cd d-; 88 % from food. Example-2: The acceptable daily intake of a toxin Tox is 10 g per day for an adult weighing 60 kg. If the concentration of Tox in striped bass is 0.2 ppm, how much of this fish can an adult weighing 60 kg eat daily without exceeding this limit? First, re-express the concentration of Tox in the fish using explicit units. Guessing that the amount of fish ingested by a person per day is on the order of grams, we will select g as the denominator: Conc of Tox in fish = 0.2 ppm = fish g Tox g 1 2 . Now find out how many grams of fish will contain a total of 10 g of Tox: fish g Tox g fish g x Tox g 1 2 . 10 = Rearrange the above and solve for x give the final answer: x = 50 g Komada 1/26/2010...
