For dioxins in fathead minnows, the BCF = 29,200. The half-life for elimination of dioxins from fathead minnows is 14.5 days.
a. For an aquatic habitat where the dioxin concentration is 0.020 ppt, what is the concentration of dioxin in fathead minnows?
b. If a fathead minnow is taken from the contaminated habitat and placed in a clean laboratory water tank, how many days will it take for the dioxin concentration in the minnow to drop to 0.10 ppb?
