Exercise 1 Heavy Metal Phytoextraction A plant accumulates a heavy metal to a bioconcentration factor of 10 (kg/kg dry weight based). There is a layer of 62.5 cm (density 1.6 kg/L = 1 ton per m 2 ) soil with 10 mg/kg of a heavy metal. Each year, the plant cover produces a net growth of 1 kg dry weight /m 2 . How long will it take until the concentration in the contaminated soil layer has fallen to 1 mg/kg, if plant extraction is the only relevant removal process?

Exercise 1
Heavy Metal Phytoextraction
A plant accumulates a heavy metal to a bioconcentration factor of 10 (kg/kg dry weight based).
There is a layer of 62.5 cm (density 1.6 kg/L = 1 ton per m2) soil with 10 mg/kg of a heavy metal.
Each year, the plant cover produces a net growth of 1 kg dry weight /m2.
How long will it take until the concentration in the contaminated soil layer has fallen to 1 mg/kg, if plant extraction is the only relevant removal process?
