Abstract

Core samples from Lake Helena at depths ranging from 20 - 200cm have been digested, filtered, and analyzed for heavy metals via Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES). ICP-AES allows for analysis of a wide range of metals of interest because each metal emits radiation at a characteristic wavelength. This study investigates the correlation between metal concentration and events such as a flood or mining. Using an internal standard of rhodium, metals such as lead, iron, manganese and zinc have been detected in varying concentrations through the range of depths.
