    Lead can be treated at a cost of $9/m2 with phytoremediation with sunflowers or $45/m3 with removal of soil by excavation. Show your work in each calculation below. a)What is the range of lead concentrations in mg/kg? b)What is the area of the primary area? What is the area of the secondary area?
