In 1982, a section of the adjacent Spring Creek was designated
as a catch and release zone for fishing as a result of high levels
of pesticides in fish.

a) Find the concentration of kepone that bioconcentrated in the
brown trout fish if concentration of kepone in the Spring Creek was
10 ppb. Assume that octanol is a good representation of the fatty
tissues of the trout fish.

b) US Food and Drug Administration (FDA) action level is 300 µg
kepone/kg fish. Show that the amount of kepone found in part a)
exceeds FDA recommendation.

Assume:

The density of the fish is1.2 kg/L

All kepone is accumulated in the fish fat

The fish has 8% fat
