Emisja Zanieczyszczeń Ze Spalania Odpadów Ściekowych W Piecu Półkowym, Robert Oleniacz, Marian Mazur, Marek Bogacki

Robert Oleniacz

The article presents incineration tests of silty-tar sludge produced in the wastewater treatment plant for coke industry. Sewage sludges were incinerated in a full-scale multiple hearth incinerator equipped with a wet flue-gas cleaning system (alkaline scrubber). Measurements of air pollutant emissions were carried out both before and after the cleaning system. The obtained results allow to conclude that the thermal utilization of sewage sludge in this type of installation might be just a little cumbersome for the environment, using the appropriate equipment for the purification of exhaust gases. The paper also specifies minimum exhaust gas cleaning performance that guarantees compliance …

Evaluation Of Constructed Wetlands For The Waste Management Of A Large Scale Swine Production Unit, Robert Sutton

Masters Theses & Specialist Projects

The effectiveness of using constructed wetlands to remove unwanted nutrients, increase dissolved oxygen while at the same time decreasing the biological oxygen demand, and to reduce the levels of the Fecal Coliform Bacteria from a swine operation was evaluated. The indicator of proper waste purification will be the result of testing for the following: ammonia nitrogen, nitrate nitrogen, total phosphorus, total suspended solids, dissolved solids, dissolved oxygen, biological oxygen demand, and Fecal Coliform Bacteria. The wetland was divided into nine connected cells that covered approximately 3.8 hectares. Material was loaded from an anaerobic holding lagoon on four separate occasions during …

Research Needs For The Risk Assessment Of Health And Environmental Effects Of Endocrine Disruptors: A Report Of The Us Epa-Sponsored Workshop, Rj Kavlock, Gp Daston, C Derosa, P Fennercrisp, Le Gray, S Kaattari, Et Al

VIMS Articles

The hypothesis has been put forward that humans and wildlife species have suffered adverse health effects after exposure to endocrine-disrupting chemicals. Reported adverse effects include declines in populations, increases in cancers, and reduced reproductive function. The U.S. Environmental Protection Agency sponsored a workshop in April 1995 to bring together interested parties in an effort to identify research gaps related to this hypothesis and to establish priorities for future research activities. Approximately 90 invited participants were organized into work groups developed around the principal reported health effects-carcinogenesis, reproductive toxicity, neurotoxicity, and immunotoxicity--as well as along the risk assessment paradigm--hazard identification, dose-response …

Rare And Endangered Plants At Gateway National Recreation Area: A Case For Protection Of Urban Natural Areas, Richard Stalter, Michael D. Byer, John T. Tanacredi Ph.D.

Faculty Works: CERCOM

The diversity of native plant species in urban environments is usually overlooked when biodiversity levels are considered. Inventories of native plants reveal many to be rare species surviving the harsh conditions encountered in urban ecosystems. Knowledge of their existence and an inventory of their distribution will assist in maintaining these populations. Protection strategies for rare plant species are outlined for urban National Parks.

The Real Cost Of Beef: A Monetary Assessment Of The Environmental Degradation Caused By Beef Production, Carolyn Babcock

UNLV Theses, Dissertations, Professional Papers, and Capstones

The environmental degradation caused by beef production is severe. The current literature assesses the ecological damage, but falls short of assigning a per pound dollar amount to reflect the real cost of beef. In the United States, most of the environmental focus has been centered around the use of public lands for grazing and the grazing fee the government considers appropriate. The fee covers the maintenance of the grazing program, which includes maintenance of the actual land. This paper will concentrate on beef-related environmental degradation and select specific damage for monetary valuation.

Based on our experience, if you don't have a customer service focus, there is no future to worry about.

Extension Wetlands Education In Texas, Darrin Bauer, Will E. Cohen

8th Triennial National Wildlife and Fisheries Extension Specialists Conference (1996)

The United States has lost more than half of the wetlands that existed prior to European settlement. Wetlands continue to be lost at an alarming rate due to human disturbance and natural processes. The loss of our countries' wetlands is costing our society greatly. Wetlands perform many functions that are beneficial, such as water filtration, recharging groundwater, providing natural flood control, and supporting a wide variety of birds, fish, mammals, amphibians, insects, and plants. Numerous commercially important fish also require wetlands to survive. Wetlands also provide many recreational opportunities.

Expectations And Future Opportunities For Fish And Wildlife Extension Programs, Jack H. Berryman

8th Triennial National Wildlife and Fisheries Extension Specialists Conference (1996)

The charge to the panel was really in the form of a question: What do customers and cooperators expect and what are the future opportunities for fish and wildlife extension programs?

It's a pretty risky subject. Each state is different; each has different problems and opportunities. And, most of the practitioners—those who know most about it— are here in this audience.

Pete Petoskey and Jim Miller have already presented some historical background and a perspective for the future. And, the fact of these workshops and a glance at the program is clear evidence of the progress being made. The professionalism, …

Balancing Split Appointments: A View From The Trenches, Margaret Brittingham

8th Triennial National Wildlife and Fisheries Extension Specialists Conference (1996)

The following comments primarily address the extension/research split but many of them are also applicable to the extension/teaching split.

Who Are Our Clientele?, Robert D. Brown

8th Triennial National Wildlife and Fisheries Extension Specialists Conference (1996)

The title of this session asks us to address what our clientele want, but I think we first need to address a more basic issue—who are our clientele, or at least who might they be in the future? We've given this a lot of thought in Texas in the past year or so, as we find that we have one of the most rapidly growing and changing states in the nation. In my position as department head in Texas, it is imperative that I be aware of those changes, and that I provide leadership as to how our extension program …

Public Issues Education In Natural Resources: Speaking As A Professional, Dave Cleaves, Paul Adams

8th Triennial National Wildlife and Fisheries Extension Specialists Conference (1996)

One certainty these days is that public policy will continue to shape the future of forestry. We foresters seem to take what's served up, wishing we had more influence on the ingredients and how they are prepared. We need to assert more leadership in providing forestry knowledge to citizens and decision-makers. However, information delivery is not enough; we need to be involved in the process of policy as well as its content. Technical information and good science will not prevail on their own. We don't have to push a particular option to be effective. We can use our skills and …

Exotic Aquatic Plants-Some Good; Some Bad, James T. Davis

8th Triennial National Wildlife and Fisheries Extension Specialists Conference (1996)

Aquatic plants, like all other plants, may be weeds in one location and a source of income and therefore coveted in another location. Introduction of exotic aquatic plants to the United States has always proceeded at a rapid rate. Many plants were brought in for horticultural or agricultural purposes. A greater number of aquatic species were brought in as aquarium plants and then accidentally or purposely introduced into the wild as a future source of income. A much lesser number have been introduced into natural waters from ballast pumpage. Most are of tropical or semi-tropical origin and initially were confined …

Importance Of Youth-A Challenge, Holly Davis

8th Triennial National Wildlife and Fisheries Extension Specialists Conference (1996)

As I was looking through your program for the next few days, I noticed that several of the workshops had to do with the future—Perspectives on Natural Resources Extension for the 21st Century, A Perspective on the Past, Present, and Future Extension Wildlife and Fisheries Programs, Extension Technologies for the 21st Century, and on and on. But it is our youth with whom we should focus. It's the young generations now that are going to be doctors, pilots of major airlines, presidents, UN Peacekeepers, but most important of all—keepers of our planet earth. Our future is going to be built …

National 4-H Sportfishing Program, Catherine A. Elliott

8th Triennial National Wildlife and Fisheries Extension Specialists Conference (1996)

In May I went to the Cornell Biological Field Station with nine volunteers from Maine to attend the pilot training for the National 4-H Sportfishing Program. While I was there, Ron Howard, chair of the program development committee, asked if I was coming to this meeting, and if so, would I speak about the sportfishing program. In the euphoria of the moment, I said yes, then immediately began to wonder why I had said yes. Although I live more than 50 miles from here, I am giving this talk without slides and I haven't been fishing for over 25 years, …

Expectations And Opportunities-View From The Profession, Erik K. Fritzell

8th Triennial National Wildlife and Fisheries Extension Specialists Conference (1996)

Extension Specialists are in a unique position to address what may become the most significant issue in professional fisheries and wildlife management in the last 50 years—the erosion of public support and confidence in government agencies to manage natural resources.

The fisheries and wildlife fields comprise a diverse community of professionals—biologists, managers, decision-makers, consultants, researchers, educators, and others. In this country, the foundation of our field is based upon the Public Trust responsibilities for wild animals. State and federal governments share the role of trustees.

Rural America faces a crisis in natural resource management. Natural resource-based economies have suffered with …

Managing Recreational Fish Ponds, Michael P. Masser

8th Triennial National Wildlife and Fisheries Extension Specialists Conference (1996)

Kentucky has over 135,000 farm ponds. These ponds are used for irrigation, watering livestock, and recreation. However, most ponds are under-utilized for recreation. Existing ponds can provide excellent recreational opportunities if properly managed.

The first step in recreational pond management is to determine the pond's purpose. Ponds can be managed for swimming, fishing, aesthetics, and to attract wildlife. It may be difficult to manage for all of these things simultaneously. The pond owner must decide about goals or what is most important. If fishing is the desired objective, the following should help.

Walk-In Hunting Area Program In Kansas, Charles D. Lee

8th Triennial National Wildlife and Fisheries Extension Specialists Conference (1996)

Hunting license sales in Kansas are declining. Hunters often cite the lack of access as a reason for no longer hunting. Some landowners are seeking opportunities to use wildlife and other natural resources as a source of supplemental income. Kansas Department of Wildlife and Parks (KDWP) initiated a pilot program to lease land and make it available for public hunting. In 1995 KDWP leased 10,345 acres of land from 46 different landowners at a lease cost of $20,400. This lease program follows a simple concept by which landowners receive a fee from the Department to allow people to hunt their …

Multimedia Programs And New Computer Technologies: A Look At Texas 4-H Wildlife School Enrichment Programs, Billy Higginbotham

8th Triennial National Wildlife and Fisheries Extension Specialists Conference (1996)

4-H multimedia school enrichment modules offer excellent wildlife educational opportunities for elementary students as we near the 21st century. Modules consisting of hands-on displays, interactive computer programs, videos, lesson plan activities, and pre/post-test components serve to reinforce information relative to topical issues in the wildlife arena. In Texas, modules have been developed entitled "The White-tailed Deer," "Wildlife Success Stories and Endangered Species," and "Something's Fishy." These modules and their duplicates are used as components of county 4-H programs and serve to deliver wildlife information to an ethnically and socio-economically diverse audience of third and fourth graders. Teacher committees are instrumental …

Fee-Fishing: Introduction And Marketing, Michael P. Masser

8th Triennial National Wildlife and Fisheries Extension Specialists Conference (1996)

Essential ingredients for a successful fee-fishing operation include: location, knowledge of clientele, facility design, providing services, advertising, and management of the fish. A fee-fishing operation is a business, a recreational people-oriented business, and not just a method to market fish.

Development And Management Of Fishing Leases, Billy Higginbotham, Greg Clary

8th Triennial National Wildlife and Fisheries Extension Specialists Conference (1996)

The popularity of developing sportfish leases is increasing rapidly in the South, much as development of hunting leases has done over the past three decades. This trend is occurring because an increasing number of: (1) landowners realize that their ponds and reservoirs are valuable resources capable of generating additional profits and (2) anglers desire a level of exclusivity not normally available on public waters. A sound economic evaluation of sportfish leasing opportunities is essential if landowners are to identify their most profitable alternatives. Net present value analysis is recommended as one method for evaluating compared profitability of selected investment and …

Training Field Staff About Wetlands And Wetland Issues: Dealing With The Unknowns-A Case History, James A. Parkhurst

8th Triennial National Wildlife and Fisheries Extension Specialists Conference (1996)

In response to an increasing number of requests for assistance from county-based extension agents in Virginia about regulatory issues relating to wetlands, an in-service training program on wetland definition, delineation, and permit review was developed and conducted in spring 1995. As a means to familiarize agents with the various wetland regulators, representatives from all agencies or organizations who have any regulatory authority over wetlands in Virginia were invited and asked to introduce and describe their agency and its responsibilities, and discuss when and how they conduct wetland permit reviews. Although an important objective of this training workshop was to help …

Finding Your Song, John Munn

8th Triennial National Wildlife and Fisheries Extension Specialists Conference (1996)

Planet Earth is a magnificent mix of things that make "living" possible. Delicate mixtures of chemicals, minerals, gases, and waters bathe us. Earth is just the right distance from our sun to provide the energy, driving all the systems—necessary for life—as we know it. Some refer to this as the Great Balance of Life.

How well are these systems balanced, and what would it take for the Planet to lose its ability to create and sustain Life?

We are all aware of the long list of environmental problems facing us. We are also aware of the scientific uncertainties that make …

Perspective On Natural Resources Extension For The 21st Century, Merrill Petoskey

8th Triennial National Wildlife and Fisheries Extension Specialists Conference (1996)

Speaking to this group of fish, wildlife, and natural resources professionals is getting to be a habit with me, having talked at this workshop three times in the past 2 decades. This is the fourth.

The first time was in 1977, I was gainfully employed as Director of Wildlife Management for the U.S. Forest Service (USFS). I'm not quite sure why I was at your meeting. I expect my good friend, Jim Miller, trapped me because of some earlier discussions we had on grazing on the Ouachita National Forest in Arkansas. Regardless, at the time, I suggested that funding, in …

Habitat Management Planning: Blending Commercial Forest Management And The Protection Of Forest Ecosystems, Including Their Wildlife Communities, James A. Rochelle

8th Triennial National Wildlife and Fisheries Extension Specialists Conference (1996)

The purpose of a Habitat Management Plan is to use the best available science, within an adaptive framework, to provide habitat for a wide variety of native forest wildlife species while profitably managing private land for wood production. This process is currently under development by Weyerhaeuser Company in Washington State. The process starts with a Watershed Analysis conducted under the forest practices laws of the state. In this analysis, technical experts of the appropriate disciplines identify the causal mechanisms behind those processes (mass wasting, surface erosion, temperature regulation, etc.) which are related to fish habitat and water quality. With knowledge …
