Abstract

The goal of this thesis research was to determine the capacity of switchgrass to degrade atrazine. The major objectives were as follows: (1) to characterize the ability of above-ground leaf material of switchgrass to take up atrazine from sand, (2) to quantify the amount of degradation occurring in the leaf biomass, (3) to quantify the amount of degradation occurring in the rhizosphere, (4) and to evaluate the uptake and degradation of atrazine in older switchgrass plants to get a better understanding of what could be expected in a field remediation study. To accomplish these objectives, atrazine was applied to soils, and its fate was monitored in laboratory and greenhouse phytoremediation settings. At the end of the respective test periods, soil and the grass tissues were evaluated for quantification and identification of atrazine and three selected metabolites.
