In Shivaji Nagar, if you are 39 years old you are most likely dead. Some in this neighborhood say it is far worse if you are alive. Yet, seemingly paradoxically, the residents of this neighborhood do not want to leave it. Located between one of Asia’s largest garbage dumps and Mumbai’s largest abattoir, this Deonar neighborhood is popularly known as “Bombay’s gas chamber.” This dissertation examines the social worlds of the residents of Shivaji Nagar by asking how an apparently odious, and potentially toxic place that appears to foreclose all possibilities other than failure, waste and death becomes an object of attachment for its residents.

Magister Scientiae (Biodiversity and Conservation Biology) - MSc (Biodiv and Cons Biol) / The study illustrates the current ecological integrity of the Diep River system, based on the recent river health assessment using the South African Scoring System version 5 (2000-2003) and the water quality data (1996-2002). Some of the major land-use impacts on the river system are highlighted.

The response of several plant species to heavy metal contaminated soils was evaluated using plant bioassays with a soil substrate. A natural soil was collected from Dinwiddie County, Virginia and soil analysis was performed. The plant species, Lolium multiflorum, setaria italica and Trifolium rep ens latum, Robinia pseudoacacia, Andropogon gerardi, Asclepias syriaca, Echinacea purpurea, Rudbeckia hirta and Festuca rubra were grown in to determine the response to cupric and cadmium chloride in soils (mg Cu/kg soil). A few plant species were grown in small pots in a plant growth chamber for 28 days using control, 10, 30, 100 and 300mg Cu or Cd/kg soil. Germination proved to be less sensitive than root length. S. italica had highest ECSOs. In eu 20.7 and 15.3 in Cd. All plant species were grown for 7 days in 0.3, 1.0, 3.0 10.0, and 30.0mg Cu/kg soil and in control. Germination was not effected by metal concentrations in most species (p=0.07-0.6), except T.repens latum, R. hirta and F. rubra at 30mg/kg (p=0.0007). Root length was significantly effected by Cu concentrations for almost all species (p=0.0001-0.0112). Setaria italica had the highest EC50 at 10.86mg/kg. Robinia pseudoacacia root length was not significantly affected by CU concentrations. The other species had EC50s ranging from 3.74-7.51mg/kg. Both inhibition and stimulation of root growth were observed. Preliminary studies regarding germination rates, fungicides and rangefinding are included. / Master of Science

The geotechnical aspects of a hazardous waste disposal site located in Piney River, Nelson County, Virginia, were investigated. The waste material consisted primarily of a by-product of the production of titanium known as copperas which is highly acidic. The investigatory program consisted of field and laboratory work. Objectives included delineating the pit geometry and liner system, assessing the characteristics of the natural soils at the site as well as the wastes, and evaluating the degree of contamination of the natural subsoils around the pit. The field investigation findings show a more complex geometry for the pit than that suggested in the design documents. While shown on the plans, the presence of the bottom clay liner is questionable. Large depressions and numerous cracks were found in the waste area. Acid contamination of the groundwater and the subsoils exists to a considerable depth. Laboratory tests illustrated the susceptibility of the copperas to dissolution under water seepage. This could have caused the large settlements. Remedial actions could include grading the top of the pit for better drainage. Other actions could include redepositing the waste in a burial pit which has a leachate collection system and properly compacted clay liners which include an impervious fabric. Perhaps the waste could be treated chemically prior to final disposition. In any case, some level of continual maintenance will be necessary. / M. S.
