of For approximately 35 years quantities of the PBC has been entering lake Michigan. Analysis of a composite sample of the bottom mud provides the data in Table 1. a. Normalize the data with respect to PCB concentration at the lake floor and the depth at L-9.25 cm and compare this concentration profile with the predicted by a steady-state diffusion model in the absence of SOURCES/SINKS. Are the data consistent with such model? b. Polar organic molecules can often be absorbed by soils. Resolve the problem by using a first-order reaction, where Ray = k CA (CA = PCB concentration) to show that the normalized profile will depend on z/L as well as on lo = k!? [p c. Compare the experimental value of the molar flux at the late floor with that predicted by the model in (b) and obtain an estimated value for lo Table 1 Depth (cm) 0 PCB concentration u (g/g) 0.36 0.29 0.2 0.75 1.25 2.25 3.25 4.25 9.25 0.08 0.09 0.04 of For approximately 35 years quantities of the PBC has been entering lake Michigan.
