Abstract : A standardized system for obtaining and testing of cores of lake bottom sediments for analysis of background and time-varying concentrations of potentially toxic materials, in particular mercury and lead, is required to allow correlation of data from various sampling sites. Core analysis includes description of structure, texture, color, and composition, measurement of pH and Eh, and determination of mercury and lead concentrations. A simple, hand-operated coring device was developed and subsequently used to obtain cores from Gravel Lake, Wright-Patterson Air Force Base, Ohio. (Author)
