| The objective of our studies is to analyze environmental impacts of Monosodium Methane Arsenate, MSMA, on aquatic habitats using the Aqua-Terra microcosm system. MSMA was applied at environmentally relevant(recommended) doses to microcosms to determine the change in biodiversity and the bio-concentration of arsenic in the aquatic plants (_Elodea Sp._) used in the microcosms as an oxygen source. The microcosms are filled with unfiltered pond water and the diversity of each microcosm was determined before application of the herbicide. After population stabilization, the herbicide is applied to the terrestrial portion of the microcosm. The herbicide is watered into the microcosm by allowing the herbicide to be filtered by soil into the aquatic portion of... |
