Figure 7. Concentrations of indeno[1,2,3-c,d]pyrene and perylene in bottom-sediment cores at four sites in Lake Mead, May 1998. Solid circles represent cesium-137 concentrations. Open circles represent cesium-137 concentrations that are less than the value plotted. Years shown indicate the approximate date of that section of the core.
