dvanced geochemical measurement capability allows us to better understand how the environment influences human health, and in turn how human activities influence the environment. The Environmental Geochemistry and Health Core Facility utilizes a new high-sensitivity geochemical instrument (an ICP-OES with CIT detector) to measure elemental compositions in water, soils, rocks, and human and other biological samples. Research covers a range of topics, from childhood lead poisoning to Antarctica climate change records. This facility is used by faculty from the School of Science, the School of Public and Environmental Affairs, the School of Engineering, and the Indiana University School of Medicine.
