Abstract
Heavy metals such as cadmium, manganese and cadmium pose as a public and environmental health concern when left unchecked. Heavy metal toxicity depends on overall exposure in terms dosage, frequency and duration. Exposures can lead to organ damage including but not limited to intestinal, liver and kidney, as well as anemia and cancer. Heavy metals may also displace needed minerals from their original place and hinder their biological function. Multiple techniques exist that are capable of detecting and determining the concentrations of trace amounts of the heavy metal contaminants. Experiments preformed will utilize conventional techniques of analyzing trace concentrations of Pb, Cd, and MN. Two techniques of atomic absorption spectroscopy have been tested and their analytical properties analyzed. Flame atomic absorption spectroscopy and atomic emission spectroscopy through an inductively coupled plasma instrument. The flame atomic absorption instrument will determine the absorbance of electromagnetic radiation as a function of concentration while the inductively coupled plasma involves intensity of emitted photons as a function of concentration. The results of these experiments will be applied to the development of novel devices capable of detecting heavy metal contaminants in biological or environmental samples.
