Environmental Protection Agency. Other known hazards of this substance include damage to the kidneys, liver and brain. Since 1,2-DCP presents health risks to humans, a method for degrading the compound to less harmful compounds is desired and is therefore the aim of this project. Data is presented on a comparison of several degradation methods including treatment with zerovalent magnesium (ZVMg) in acidified ethanol, emulsified zero-valent magnesium (EZVMg) and polymer stabilized zero-valent magnesium (PSZVMg). Gas chromatography is used for analysis of 1,2-DCP and its degradation byproducts. The benefits and challenges of headspace solid phase micro-extraction and automated headspace analysis are also compared.
10:45 a.m. ENV-08 Quantifying Everglades peat using geospatial techniques and historical data. T. W. DRESCHEL and S. M. HOHNER. South Florida Water Management District, 3301 Gun Club Road, MSC: 4352, West Palm Beach, FL 33406. The Florida Everglades is a patterned peatland which once covered about 1.1 million hectares (2.7 million acres) of south Florida and now covers approximately 0.6 million hectares (1.5 million acres). The peat of the Everglades is formed from sawgrass or other aquatic plant material that has accumulated over millennia, with decomposition limited by inundation. Drainage for agricultural and urban development has had a significant impact on the amount of peat currently present in the Everglades. In this study, we utilized spatial data sets developed for the Everglades surfaces. The South Florida Topography Project provided the data for current peat surface. The predrainage Everglades surface was obtained from the South Florida Water Management District’s Natural Systems Regional Simulation Model. The bedrock surface was constructed using a bedrock map of the Everglades region published by Garald Parker and his colleagues in 1955. We used these surfaces to calculate the original volume of peat present in the Everglades and the current volume of peat in the Everglades. We then projected regional soils values for bulk density and carbon content using USEPA R-EMAP data, evaluated various geospatial techniques for applicability and used these volumes and the R-EMAP data to calculate the mass and carbon content of the predrainage and current volumes of peat in the Everglades. The predrainage Everglades was about 1.1 million hectares in size and contained on the order of 20 billion cubic meters of peat, massing 3 billion metric tons. The current Everglades is about 6 hundred thousand hectares in size and contains on the order of 5 billion cubic meters of peat, massing 500 million metric tons. 11:00 a.m. ENV-09 Concentration of soil nutrients: Carbon, Nitrogen, and Phosphorus in soil surrounding pond apple, Annona glabra, in a cypresspond apple swamp in the Arthur R.
