5. You are cooking beef soup. According to chemical analysis, unfortunately, beef contains 0.2 ng 2,3,7,8-TCDD per kg beef. Fat content of beef is 5% (i.e., 2 g per 40 g). You put 40 g beef to make one liter soup. After cooking, you see drops of oil floating over the soup. The volume of all floating oil drops is estimated 2 mL. Octanol/water partition coefficient of 2,3,7,8-TCDD is 10°*. (a) Estimate the concentration of 2,3,7,8-TCDD in floating oil drops. State any required assumption(s). 6.4 (b) How much you can reduce the intake of 2,3,7,8-TCDD by removing all floating oil drops? 5. You are cooking beef soup.
