The paper presents the results of many years of complex research issues related to the emission of fluorine compounds of iron and steel processes. They allowed to examine these processes used in raw materials in terms of the fluorine content and their impact on the amount of emissions of fluorine compounds to the air. Were determined by measuring the levels of concentration in flue gases and stack emissions of fluorine in the form of gaseous and solid compounds, including water-soluble components (considered to be toxic).

English title: Analysis of emission sources of fluorine compounds from the processes of ferrous metallurgy.

Spalanie Odpadów Niebezpiecznych W Piecach Cementowych. Część 2. Destrukcja Paliwa I Emisja Zanieczyszczeń, Robert Oleniacz

Robert Oleniacz

Conditions occurring in cement rotary kilns assure high destruction and removal efficiency (DRE) of the most stable substances, efficacious dry sorption of acid gases in the alkaline raw meal and heavy metals bounding in the clinker. Adequate operation of hazardous waste incineration in the process connected with cement clinker production does not cause increasing air pollutant emissions. Magnitude of the emissions often does not depend of this if there are using wastes in the cement kiln at all. The work presents a review of DRE levels and stack emissions for selected flue-gas constituents during hazardous waste co-combustion in cement kilns ...

In order to share and properly interpret the data, the Bureau of Reclamation, Southern Nevada Water Authority and the three Wastewater Treatment Facilities (City of Las Vegas, Clark County Sanitation District and City of Henderson) formed a committee to examine sampling and analytical protocols and to share information with the goal of maximizing the data quality. The group first met in April 1997.

It was agreed that an effort should be made to discuss and compare specific sampling and analytical techniques ...


Vegetation Analysis: A Graphical Analysis Of Plant Succession In Desert Communities Affected By Fire, Jeff Lantow Oct 1998

Vegetation Analysis: A Graphical Analysis Of Plant Succession In Desert Communities Affected By Fire, Jeff Lantow

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Mojave Desert is affected by fire every year. With each fire comes the removal of old growth and, in its place, new growth – consisting primarily of those species which thrive in disturbed areas. The focus of my research is to look at plant communities that have been disturbed by fire, and examine the successional pathway of these disturbed environments. The seven environments I analyzed were burned within the last twenty years and are found in the Coleogyne ramosissima ecotone throughout the Spring Mountain range near Las Vegas, Nevada. The data was collected with randomly chosen circle plots in the ...

The Rocky Flats Environmental Technology Site is located in Golden, Colorado. It is situated on 384 acres in a 6,550-acre natural preserve. Rocky Flats ended its original mission in 1989, after raids on the site by both the FBI and the EPA for illegal dumping and other environmental violations. Since then the site has been scheduled for cleanup. This thesis will provide background information on the site and on the company hired to perform the cleanup. It also provides an evaluation of some key policies regarding the cleanup procedures. Since the end of the cold war, the production of ...


Lead Shot Concentration In Soil At The Overton Wildlife Management Area, Nevada, George R. Bertoty Oct 1998

Lead Shot Concentration In Soil At The Overton Wildlife Management Area, Nevada, George R. Bertoty

UNLV Theses, Dissertations, Professional Papers, and Capstones

During the spring of 1998, soil samples were collected from two areas at the Overton Wildlife Management Area (OWMA), located in the Moapa Valley of Clark County, Nevada. Lead shot has been banned for the hunting of waterfowl since 1986 but is still legal for upland game hunting. Both types of hunting occur at OWMA. One area sampled is a cultivated field and serves primarily as a dove hunting area. The other area is primarily a waterfowl hunting area and is flooded during the waterfowl-hunting season. Lead shot was recovered from 83% of the samples from the dove hunting area ...


Estimating Atrazine Leaching In The Midwest, Michael R. Burkart, Philip W. Gassman, Thomas B. Moorman, Piyash Singh Oct 1998

Estimating Atrazine Leaching In The Midwest, Michael R. Burkart, Philip W. Gassman, Thomas B. Moorman, Piyash Singh

CARD Working Papers

Data from seven Management Systems Evaluation Areas (MSEM) were used to test the sensitivity of a leaching model, PRZM-2, to a variety of hydrologic settings common in the Midwest. Atrazine leaching was simulated because the use of atrazine was prevalent in the MSEA studies and it frequently occurs in the region's groundwater. Results of long-term simulations using regional and generalized input parameters produced ranks of leaching potential similar to those based on measurements. Short-term simulations used site-specific soil and chemical coefficients.

Spalanie Odpadów Niebezpiecznych W Piecach Cementowych. Część 1. Informacje Podstawowe, Robert Oleniacz

Robert Oleniacz

A widely employed method of reducing cement production costs is the substitution of traditional fuels with alternative and waste-derived fuels to heat the cement kiln. Cement industry offers the most acceptable method of hazardous waste incineration and co-combustion with significantly lower cost in comparison to incinerators. The high temperatures and long residence times inherent in the operation of cement kilns ensure the almost complete destruction of the organic compounds introduced together with waste fuels. This part of the article presents general characteristic of sort of waste incinerated in cement kilns, way of their charging, advantages and limitations of waste co-combustion ...

Gray Wolf (Canis Lupus) Jul 1998

Gray Wolf (Canis Lupus)

Rocky Mountain Wolf Recovery Annual Reports

Historically, most Native Americans revered gray wolves, trying to emulate their cunning and hunting abilities. However, wolves became nearly extinct in the lower 48 states in the early part of the 20th century because settlers believed wolves caused widespread livestock losses. Constantly persecuted and targeted by large scale predator eradication programs sponsored by the federal government, wolves have been pursued with more passion and determination than any other animal in U.S. history. By the time wolves were finally protected by the Endangered Species Act of 1973, they had been exterminated from the lower 48 states, except for a few ...


The Price Of Clean Air: A Consideration Of Market Based Emissions Trading, Mark W. Miller May 1998

The Price Of Clean Air: A Consideration Of Market Based Emissions Trading, Mark W. Miller

UNLV Theses, Dissertations, Professional Papers, and Capstones

Traditional regulatory approaches for environmental protection do not consider

the costs and benefits of the standards they impose. Further, imposing strict performance

standards on firms with heterogeneous control costs leads to an inefficient allocation of resources devoted to pollution control. This paper explores the use of emission allowance trading as a way to improve economic efficiency within the context of environmental protection. PM10 air pollution from sources within the Las Vegas Valley is used as the case study.

This paper found that an emission trading

program in this particular case study would not live up to the theoretical expectations. Although ...


Measuring The Applicability Of The Seville Strategy To The Mammoth Cave Area Biosphere Reserve, Debra Kreitzer May 1998

Measuring The Applicability Of The Seville Strategy To The Mammoth Cave Area Biosphere Reserve, Debra Kreitzer

Masters Theses & Specialist Projects

The dominant paradigms of the past decade involve the preservation of biodiversity through the use of landscape corridors and buffer zones, as well as the integration of economic growth through sustainable use. The International Biosphere Reserve (IBR) program, as defined in the Seville Strategy, encourages locations already involved in conservation to continue to protect biodiversity and foster harmonious relationships between humans and their environment through sustainable development. An excellent example of an IBR is the Mammoth Cave Area Biosphere Reserve (MCABR) in south-central Kentucky. In order to measure the significance of the implementation of the Seville Strategy in the MCABR ...

Field research was conducted from Purdue University during 1991 to 1993 to examine some aspects of the efficaciousness of the various types of glue traps against wild populations of house mice. The research was conducted in agricultural and livestock buildings containing various infestation levels of mice. Tests compared the capture and escape rates of glue boards vs. trays, covered vs. uncovered glue traps, and glue traps vs. snap traps, and multiple catch curiosity traps. Observational work, via night vigils, was also conducted to note the behavioral response of mice to glue surfaces, including the behavioral aspects of mice neutralizing glue ...


Development Of An Internet Center For Wildlife Damage Management (Html.Www.Ianr.Unl/Wildlife), Scott E. Hygnstrom, Robert H. Schmidt, Paul D. Curtis, Greg K. Yarrow Mar 1998

Development Of An Internet Center For Wildlife Damage Management (Html.Www.Ianr.Unl/Wildlife), Scott E. Hygnstrom, Robert H. Schmidt, Paul D. Curtis, Greg K. Yarrow

Proceedings of the Eighteenth Vertebrate Pest Conference (1998)

Wildlife damage problems are experienced by all segments of society. Row crops, forages, rangeland, fruits, vegetables, ornamentals, and turf are all susceptible to wildlife damage at various stages of development. Agricultural producers lose billions of dollars each year due to crop damage caused by deer, voles, blackbirds, and other wildlife species (Conover et al. 1995). In addition, over 75,000 people are injured annually or become ill in North America due to wildlife-related incidents. For most of these problems, IPM principles can be applied to reduce damage to tolerable levels. Information, materials, and services on wildlife damage management are available ...


Management Of Conflicts Between Urban Coyotes And Humans In Southern California, Rex O. Baker, Robert M. Timm Mar 1998

Management Of Conflicts Between Urban Coyotes And Humans In Southern California, Rex O. Baker, Robert M. Timm

Proceedings of the Eighteenth Vertebrate Pest Conference (1998)

An apparent increase in coyote-human conflicts, notably attacks on humans, demonstrates that such incidents are not rare in California. The authors discuss coyote attacks on 53 humans, resulting in 21 instances of human injury, over the last decade. These illustrate repeated, predictable pre-attack coyote behavior patterns. Specific changes in human environments and in human behavior that have contributed to coyote attacks are discussed. Case histories of attacks reveal contributing factors and suggest appropriate corrective and preventive actions. Padded leghold traps have been the most effective and efficient tool in removing problem coyotes and changing the behavior of coyotes to fear ...

Research And Management Of Bird Depredations At Catfish Farms, Mark E. Tobin Jan 1998

Research And Management Of Bird Depredations At Catfish Farms, Mark E. Tobin

Proceedings of the Eighteenth Vertebrate Pest Conference (1998)

Depredations by fish-eating birds are a major constraint on production at commercial catfish facilities in the southeastern United States. A recent survey of catfish farmers estimated total losses due to direct predation by birds and costs associated with employing preventive measures at $17 million, or 4% of national sales. In 1988, the U.S. Department of Agriculture's (USDA) National Wildlife Research Center (NWRC) established a research station in Mississippi to develop more effective methods for reducing the impact of birds on southeastern aquaculture farms. This paper describes the impact of double-crested cormorants (Phalacrocorax auritus, DCCO) on the catfish industry ...


Rat Management For Endangered Species Protection In The U.S. Virgin Islands, Gary W. Witmer, Earl W. Campbell Iii, Frank Boyd Jan 1998

Rat Management For Endangered Species Protection In The U.S. Virgin Islands, Gary W. Witmer, Earl W. Campbell Iii, Frank Boyd

Proceedings of the Eighteenth Vertebrate Pest Conference (1998)

Introduced roof rats (Rartus rattus) pose a substantial threat to the fauna and flora of many tropical islands. In the Caribbean, there is concern about rat impacts to several endangered species, including the Atlantic hawksbill sea turtle (Eretmochelys imbricata) and the least tern (Sterna antillarum). The authors surveyed the rat population on Buck Island, Buck Island Reef National Monument, U .S. Virgin Islands in February 1998. Based on three nights of trapping, rats were of low to moderate abundance during the sampling period when compared to results from other Caribbean islands. The impact of rats on native vegetation was evident ...


The Bait Surcharge Program: Research Improves Zinc Phosphide Use For Vole Control In Alfalfa, Ray T. Sterner Jan 1998

The Bait Surcharge Program: Research Improves Zinc Phosphide Use For Vole Control In Alfalfa, Ray T. Sterner

Proceedings of the Eighteenth Vertebrate Pest Conference (1998)

This paper describes several unexpected benefits of rodenticide-registration research funded by The California Bait Surcharge Program. An enclosure-type study was conducted to determine efficacy of single, pre- and test-bait broadcasts (10 lb./ac.) of 0% and 2% zinc phosphide (Zn3P2, CAS #1314-84-7) steam-rolled-oat (SRO) groats to control voles (Microtus spp.) in alfalfa (Medicago sariva). Unexpected research spinoffs resulted from the use of: 1) eight randomly-located, sieved-dirt plots per enclosure to monitor bait distribution, bait removal, and rodent/avian (non-target) activity; 2) a bait-weathering plot and bait-sample analyses to monitor Zn3P2 biodeterioration; and 3) a ...


The Use Of Aerosol Repellents As An Avian Deterrent Strategy, Gwen R. Stevens, Larry Clark, Richard A. Weber Jan 1998

The Use Of Aerosol Repellents As An Avian Deterrent Strategy, Gwen R. Stevens, Larry Clark, Richard A. Weber

Proceedings of the Eighteenth Vertebrate Pest Conference (1998)

Traditional protective measures to keep wildlife away from areas include exclusion by use of netting, hazing, and chemical repellents. The primary problem with most hazing systems is that wildlife quickly habituate to the devices if their use falls into a predictable pattern. Repellent substances cause wildlife species to avoid otherwise attractive or palatable resources by creating a disincentive to visit a specific area or consume a particular resource. Chemical repellents, both lethal and non-lethal, are typically used for agricultural and horticultural purposes, but in addition may provide a strategy to deter wildlife in other contexts. Aerosol delivery of chemical repellents ...


Effects Of Taste Stimuli (Quinine And Sucrose) In Pelleted Granulated, And Wax Block Baits On Feeding Preferences Of Northern Pocket Gophers (Thomomys Talpoides), Stephen A. Schumake, Geraldine R. Mccann Jan 1998

Effects Of Taste Stimuli (Quinine And Sucrose) In Pelleted Granulated, And Wax Block Baits On Feeding Preferences Of Northern Pocket Gophers (Thomomys Talpoides), Stephen A. Schumake, Geraldine R. Mccann

Proceedings of the Eighteenth Vertebrate Pest Conference (1998)

A two-choice, taste preference study was conducted using 18 northern pocket gophers to evaluate pelleted sorghum, granulated sorghum, and wax block baits containing either 0.01 to 0.05 % quinine or 0.10 to 5.0 % sucrose. Bait consumption was significantly higher across treatments (P≤.001) for granulated sorghum, followed by pelleted sorghum, and wax blocks. Gophers also showed a high frequency of moving the granulated bait in their cheek pouches to be deposited at alternate locations within their cages. Although increasing sucrose concentration did not produce significantly (P ≥.10) enhanced consumption for any of the baits, a trend toward ...


Managing Island Biotas: Brown Treesnake Control Using Barrier Technology, Gad Perry, Earl W. Campbell Iii, Gordon H. Rodda, Thomas H. Fritts Jan 1998

Managing Island Biotas: Brown Treesnake Control Using Barrier Technology, Gad Perry, Earl W. Campbell Iii, Gordon H. Rodda, Thomas H. Fritts

Proceedings of the Eighteenth Vertebrate Pest Conference (1998)

The brown treesnake (Boiga irregularis), accidentally introduced to the previously snake-free U.S. island of Guam after World War 11, decimated the island's naive wildlife. Today, it periodically stows away on craft going to other islands where the ecological damage may be repeated. Barriers offer an effective tool for keeping the snakes out of areas from which they can disperse off-island, as well as sites identified as critical for the protection of human health, conduct of economic activity, or conservation of endangered species. The authors have developed a variety of barrier designs which repulse at least 95% of snake ...


The Impact Of Timber Management On The Phytochemicals Associated With Black Bear Damage, Dale L. Nolte, Bruce A. Kimball, Georg J. Ziegltrum Jan 1998

The Impact Of Timber Management On The Phytochemicals Associated With Black Bear Damage, Dale L. Nolte, Bruce A. Kimball, Georg J. Ziegltrum

Proceedings of the Eighteenth Vertebrate Pest Conference (1998)

Black bears forage on Douglas-fir vascular tissue in the spring, and this behavior can be severely detrimental to the health and economic value of a timber stand. Foraging is selective in that not all stands are damaged and, within a stand, one tree may be stripped while its neighbor is ignored or minimally sampled. A series of studies was conducted to assess whether bear selectivity is affected by chemical constituents within vascular tissue, and whether these constituents are affected by silvicultural practices. The results are interpreted to identify forest practices that may alleviate damage, or at least predict where damage ...


Deer On Airports: An Accident Waiting To Happen, Sandra E. Wright, Richard A. Dolbeer, Andrew J. Montoney Jan 1998

Deer On Airports: An Accident Waiting To Happen, Sandra E. Wright, Richard A. Dolbeer, Andrew J. Montoney

Proceedings of the Eighteenth Vertebrate Pest Conference (1998)

The authors analyzed data on civil aircraft strikes with wild ungulates (deer [Odocoileus spp.], elk [Cervus canadensis] and moose [Alces alces]) in the U.S. from the Federal Aviation Administration (FAA) Wildlife Strike Database and the National Transportation Safety Board (NTSB) Aviation Accident Database for 1983 to 1997. Prior to 1991, the FAA Form 5200-7 for reporting strikes was designated solely for bird strike data, thus, strike reports for non-avian species prior to 1991 are underrepresented. A total of 343 ungulate strikes was reported, 48 from 1983 to 1990 and 295 from 1991 to 1997. Forty-four states reported ungulate strikes ...
