A Plan Of Study Submitted To The Florida Department Of Environmental Regulation Southwest District, Department Of Sanitary Sewers Bay Study Group

Reports

The proposed study will examine effects of nutrient limitation on phytoplankton growth rates in Tampa Bay. The response of growth rate to changes in nutrient additions will be indicated through changes in algal biomass (chlorophyll-a) and fixation of CO2 (C‑14­ uptake). The selected method is similar to methods currently used by the states of Maryland and Virginia for determination of nutrient limitation in Chesapeake Bay waters (Fisher et al. 1992a and b). The proposed study will, therefore, not only yield valuable information about nutrient limitation in Tampa Bay, but will also allow for comparison of information between Tampa Bay and …

Pesticides are commonly used in the poultry industry for fly and litter beetle contro land are often a component of the surface-applied poultry waste. No information exists in the scientific literature regarding the transport of this pesticide component to nearby water supplies.Our research focused on cyromazine, a feed-through larvicide used to control flies in caged-layer hen houses. Tetrachlorvinphos and carbaryl are also used in poultry waste, but these pesticides have a …

Measurement Of The Effects Of Food Preparation Activities On The Microclimate Of The Snowball Dining Room Area Of Mammoth Cave, Kelly Kaletsky

Masters Theses & Specialist Projects

The stability of Mammoth Cave’s microclimate has never undergone extensive investigation. The Snowball Dining Room area was chosen to measure the microclimate of the cave and to determine if food preparation, human presence and surface temperature variations alter this microclimate. Three portable weather stations containing a temperature / humidity probe, datalogger and microbarograph were placed in various locations along three passageways leading away from the dining room. Readings were taken 24 hours per day for four months. Plotting temperature readings in graph form show a correlation between temperature of the passageway and distance from the dining room.

Fage Measurements Of Tropospheric Ho With Measurements And Model Of Interferences, Thomas M. Hard, A. A. Mehrabzadeh, C. Y. Chan, Robert J. O'Brien

Environmental Science and Management Faculty Publications and Presentations

Ambient HO measurements by low-pressure laser-excited fluorescence with chemical modulation, and supporting ozone and water-vapor data, are presented for periods in May and August 1987. The observed peak daytime ambient HO concentrations in Oregon are in the range (2.5 to 8) times106 molecules cm⁻³ and show small negative offsets due to photochemical interference. Direct measurements of the interference at fixed [O₃] give the dependence on ambient [H₂O] and on the modulating reagent [isobutane]. At ambient [O₃]=30 p.p.b. and 10 torr H₂O, with excitation and detection at a total pressure of 4 torr, the net interference is equal to [HO]=-1.3times10⁶ molecule …

Diurnal Ho₂ Cycles At Clean Air And Urban Sites In The Troposphere, Thomas M. Hard, C. Y. Chan, A. A. Mehrabzadeh, Robert J. O'Brien

Environmental Science and Management Faculty Publications and Presentations

HO₂ concentrations have been determined at two Oregon sites for continuous periods of 36 to 48 hours, using fluorescence assay with gas expansion. At the sea level coastal site (45degN 124degW), NNW winds prevailed during daytime, and a point measurement of very low total nonmethane hydrocarbon concentration indicated the presence of remote tropospheric air of oceanic origin. At the urban site, HO₂ was determined during moderately low ozone pollution levels. At both sites, maximum daily [HO₂] was in the range of 1-2times10⁸ cm⁻³ under clear-sky conditions, with an estimated overall uncertainty of 40%.

Thermal Oxidative Decomposition Of Chlorobenzene In A Tubular Flow Reactor, Jian Liu

Theses

The thermal reaction experiments of chlorobenzene decomposition were carried out in a tubular flow reactor in hydrogen and oxygen mixtures ranged from 1% to 5% at one atmosphere total pressure. Experiment temperatures were varied over a range of 590--640°C. Residence times ranged from 0.3 to 2.0 seconds.

It was found that the decomposition of chlorobenzene increased with both temperature and residence time. The oxidation of chlorobenzene occurred more rapidly when oxygen concentration was increased. 95% decomposition of chlorobenzene occurred at 620°C, O₂/H₂ = 5%, and two seconds residence time.

The major products were benzene and HCl, and …

Irreversible Immobilization Of Heavy Metal, Hyoung-Seog Ko

Theses

Heavy metals are contaminants of both solid and liquid wastes. For example, the ash produced from the incineration of domestic or industrial wastes often contains substantial concentration of lead, mercury, cadmium and other heavy metals that make it a hazardous waste. These heavy metals in wastes are hazardous because they are mobile. Immobilization of the metals is an effective method of rendering the metals harmless, provided that immobilization is irreversible. This study focused on the heavy metal immobilization potential associated with the activities of anaerobic bacteria known as the dissimilatory sulfate reducers (Postgate, 1984). The sulfate-reducing bacteria produce sulfide and …

Microwave Treatment Of Hazardous Wastes : Feasibility Studies - Operating Costs, Yongping Lu

Theses

Pilot plant studies have been carried out on a process for the remediation of soils contaminated with volatile organics (VOCs) and semi-volatile organics (SVOCs) by microwave-assisted steam distillation that had been developed in benchscale studies. The major concern had been that the process is based upon the use of electrical energy, and thus could not be competitive with fossil fuel based technologies like incineration. That concern was addressed in the pilot plant studies.

A pilot plant rated at 6 kW power and a cavity of approximately 60 cubic feet was used. In studies carried out on a water load it …

Measurement Of Vocs Pollution From Recycling Petroleum Contaminated Soils In Hot Mix Asphalt Concrete, Yaoqing Chen

Theses

The petroleum contaminated soils (PCSs) due to leaking underground storagetanks are required to be removed and isolated in a designated area for proper treatment. Recently, a technique of recycle has been developed to incorporate PCSs into hot mixing asphalt (HMA) as a partial substitute for stone aggregate; the mixture then was used for road paving.

This study focuses on the estimation of the emission of volatile organic compounds from the process of mixing asphalt with PCSs and the contamination of ground water by paving the asphalt mixture made with PCSs. Eleven volatile organic compounds and total non-methane organic compounds emitted …
