Abstract

This thesis examined heavy metal concentrations of sediments from accreting and eroding beaches along the coast of Guyana to determine if differences occurred between the two beach types as well as within both beach types. A total of 24 samples were taken from two separate beaches and were subjected to dry sieving analysis. Discriminant analysis and analysis of variance were conducted to determine if accreting beaches, with smaller grain-sizes and eroding beaches, with larger grain-sizes exhibit contrasting concentrations of heavy metals. Two separate series of line graphs were constructed to ascertain whether spatial variations in the concentrations of heavy metals were discernible and distinct in both across-shore and along-shore directions within accreting and eroding beaches. Lastly, correlation and regression analysis was performed to reveal the role of grain-size in the spatial distribution of heavy metals. (Abstract shortened by UMI.)Dept. of Earth Sciences.
