Microbial Activity in "Overland Flow" Industrial Waste Treatment

Description: One of the major problems of modern industries concerns the disposal of waste materials without the concomitant pollution of the environment. Several food and wood products industries have solved this problem by using the "overland flow" method of waste treatment. The research described in this paper was undertaken to ascertain the fact that the waste purification occurring on the disposal field is the result of microbial activities in the soil, and to study the transformations taking place.

Atrazine Monitoring and Modeling in the Lake Lavon Watershed

Description: This report describes a study to identify the distribution and extent of areas potentially at risk for atrazine (a broad leaf weedkiller) runoff in the Lake Lavon watershed, which is a major water supply for the Dallas area. The report presents the results of the study and makes recommendations for how information can be used in a cost-effective watershed atrazine reduction strategy.

Streamlining climate change and air pollution reporting: Final Report

Description: The environmental policies currently being negotiated are likely to require Member State (MS) to control and report their emission of greenhouse gases (GHG) and air pollutants (AP) more precisely. While there are likely to be associated costs, it is also likely that the cost of timely and targeted action will be less than the longer term cost of inaction. A number of European Union (EU) legal instruments are used to regulate emissions - several of these are under review. The review not only needs to anticipate future policy needs but also assess the alignment of the various instruments and whether the burden on users can be further minimized.

Evaluation of the Use of the Bivalves Ischadium recurvum Rafinesque, 1820 and Corbicula fluminea Muller, 1774 as Biological Indicators of Relative Water Quality in Terms of Growth and Upper Temperature Tolerance

Description: Growth of mussels under laboratory conditions was examined under various food regimes in different water types and temperatures. Growth was less than would be useful as an indicator and comparisons with field exposures were of minimal value. The effects of organophosphates on bivalves were examined via toxicity tests, tissue concentration, and by controlling exposure through the use of physical constraints. Upper temperature tolerance of both bivalve species was examined with respect to different acclimation temperatures and organophosphate exposures. Deviations from control exposures occurred at some temperatures. Copper effectively lowered the mean heat coma temperatures of C. fluminea at some concentrations, however, chlorine exposures did not alter heat coma temperature.

Toward a philosophy of water: Politics of the pollution and damming along the Ganges River.

Description: This thesis sets out to develop a beginning of a philosophy of water by considering philosophical implications of ecological crises currently happening along the waters of the Ganges River. In my first chapter, I give a historical account of a philosophy of water. In my second chapter, I describe various natural and cultural representations of the Ganges, accounting for physical features of the river, Hindu myths and rituals involving the river, and ecological crises characterized by the pollution and damming of the river. In my third and final chapter, I look into the philosophical implications of these crises in terms of the works of the contemporary philosopher Bruno Latour.
