Ben Odhiambo Kisila and Leanna Giancarlo Publish Paper

Ben Odhiambo Kisila, associate professor of Earth and Environmental Science, and Leanna Giancarlo, associate professor of Chemistry, have had their collaborative study, “Sediment trace metals and PCB input history in Lake Anna, Virginia, USA,” published in the July issue of the peer-reviewed journal Environmental Earth Sciences.  This research, involving undergraduate students Gayle Armentrout, Virginia Brown and Chelsea Wegner, constitutes a four-year investigation to construct a historical record of Lake Anna, extending through Louisa, Orange, and Spotsylvania Counties in Northern Virginia, by analysis of sediment cores, from seven locations within the lake and three from nearby areas, for heavy metals and polychlorinated biphenyls (PCBs).  Chemical specific analysis of these samples enables an examination of the environmental evolution of the reservoir system since sediments sequester metals derived from both natural and anthropogenic sources and isotopic sediment chronology provides the temporal dimension.
