AB: Mercury contamination in the Oxford, Alabama, area is well documented in soil tests in the Snow Creek watershed. In this investigation, mercury levels in soils as well as local plant species were examined. The objectives of the study were first determining the amount of mercury in the soil and then to determine to what degree this mercury is taken in by plant tissue from specimens at each survey site. Variation in accumulation within the individual plant species (leaves, stems) was also examined. Protocols developed for this study were used to achieve both objectives and also to ascertain if a particular plant species hyper accumulates this toxin at levels that would make it useful in bioremediation of mercury contamination in the area.
