Fish Acute Toxicity Syndromes And Their Use In The Qsar Approach To Hazard Assessment, Steven P. Bradbury, James M. Mckim, Gerald J. Niemi
Fish Acute Toxicity Syndromes And Their Use In The Qsar Approach To Hazard Assessment, Steven P. Bradbury, James M. Mckim, Gerald J. Niemi
Steven P. Bradbury
Implementation of the Toxic Substances Control Act of 1977 creates the need to reliably establish testing priorities because laboratory resources are limited and the number of industrial chemicals requiring evaluation is overwhelming. The use of quantitative structure activity relationship (QSAR) models as rapid and predictive screening tools to select more potentially hazardous chemicals for in-depth laboratory evaluation has been proposed. Further implementation and refinement of quantitative structure-toxicity relationships in aquatic toxicology and hazard assessment requires the development of a "mode-of-action" database. With such a database, a qualitative structure-activity relationship can be formulated to assign the proper mode of action, and …
Physiological Response Of Rainbow Trout (Salmo Gairdneri) To Acute Fenvalerate Lntoxication, Steven P. Bradbury, James M. Mckim, Joel R. Coats
Physiological Response Of Rainbow Trout (Salmo Gairdneri) To Acute Fenvalerate Lntoxication, Steven P. Bradbury, James M. Mckim, Joel R. Coats
Steven P. Bradbury
The physiological responses of rainbow trout (Salmo gairdneri) to fenvalerate intoxication during aqueous exposure were examined to provide information about the pyrethroid mode of action in fish. Trout (n = 4) were exposed to 412 ± 50 μg/liter fenvalerate and died in 10.9 ± 1.5 hr. Brain, liver, and carcass fenvalerate concentrations associated with mortality were 0.16 ± 0.05, 3.62 ± 0.57, and 0.25 ± 0.05 mg/kg, respectively. Visible signs of intoxication included elevated cough rate, tremors, and seizures. Histopathological examination of gill tissue showed damage consistent with irritation. An evaluation of respiratory-cardiovascular and blood chemistry responses indicated an elevated …
Estimating The Value Of Water Quality Improvements In A Recreational Demand Framework, Nancy E. Bockstael, Catherine Kling, W. Michael Hanemann
Estimating The Value Of Water Quality Improvements In A Recreational Demand Framework, Nancy E. Bockstael, Catherine Kling, W. Michael Hanemann
Catherine Kling
With the advent of Executive Order 12291, policymakers involved in water quality regulation are increasingly interested in assessing the benefits of their programs. Several methods for valuing water quality improvements using recreational demand models have been developed by economists, most of which depend on observing recreationists visiting an array of sites with varying water quality and costs of access. In this paper, three general types of models are described: systems of demands, discrete choice models, and the hedonic travel cost approach; the latter two models are demonstrated using a common data set on water quality and swimming behavior in the …
The Exclusive Economic Zone-Considerations For Management With Special Reference To Developing Nations, John G. Catena
The Exclusive Economic Zone-Considerations For Management With Special Reference To Developing Nations, John G. Catena
Theses and Major Papers
Having successfully initiated and developed the legal aspects of the Exclusive Economic Zone (EEZ) the challenge which now arises for the developing coastal nations is to implement an ocean management system to more fully realize the potential benefits of extended jurisdiction. This study discusses the needs and problems developing nations may encounter in developing such a management system and also considers the ways and means to meet these needs and overcome these problems. The study suggests that coastal nations should adopt an integrated three phased ocean policy process consisting of a (1) priority establishment phase (policy formulation) (2) strategic phase …
Balancing Conservation And Development In Maryland's Coastal Zone: A Program Evaluation, James G. Turek
Balancing Conservation And Development In Maryland's Coastal Zone: A Program Evaluation, James G. Turek
Theses and Major Papers
An evaluation of a federal regulatory program administered by the Baltimore District Corps of Engineers (COE), governing certain development activities in Maryland's coastal zone, was conducted to (1) identify cumulative development and wetland impact outcomes that occurred over a 5-year (1981-1985) period; and (2) assess a component of the decision-making process that resulted in these outcomes. This study focuses specifically on program coordination between the COE and the National Marine Fisheries Service (NMFS) to evaluate how the process has been affected by (1) programmatic changes resultant of the Reagan Administration's regulatory reform; and (2) societal demands as indicated by changes …

A Prototype For Quality: Bryce Canyon National Park Interpretive Prospectus, 1987, United States Department Of The Interior, National Park Service
Parks and Reserves
To ensure maximum coordination of message delivery, personal service efforts should be orchestrated as a result of annual (winter season) planning sessions involving TW Services, Bryce/Zion Trail Rides, and park personnel. Such planning should coordinate general summer season schedules, brainstorm new program ideas and service proposals, and establish procedures for monitoring and evaluation. This is also an opportunity to identify high priority messages regarding resources, events, new services, and park management pertinent in the coming season; in this manner, emphases for seasonal training are established.
An Inventory And Condition Survey Of Rangelands In The Carnarvon Basin, Western Australia, A L. Payne, G F. Spencer, P J. Curry
An Inventory And Condition Survey Of Rangelands In The Carnarvon Basin, Western Australia, A L. Payne, G F. Spencer, P J. Curry
Technical Bulletins
The inventory and condition survey of rangelands in the Carnarvon Basin, undertaken by the Department of Agriculture and Food, Western Australia (DAFWA) between 1980 and 1982, describes and maps the natural resources of the region’s pastoral leasehold land. This survey report provides a baseline record of the existence and condition of the natural area’s resources, to assist with the planning and implementation of land management practices. The report identified and described the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. It also assessed the impact of pastoralism and made land management recommendations. The area surveyed covers …
The Incorporation Of Environmental Perception Information Into Wilderness Park Safety Planning, Thomas Craig Waldichuk
The Incorporation Of Environmental Perception Information Into Wilderness Park Safety Planning, Thomas Craig Waldichuk
Theses and Dissertations (Comprehensive)
The park safety planning process currently in use limits users’ inputs to accident statistics. It would be better to more accurately anticipate accident-prone locations and to take preventative measures. A planning methodology is proposed which integrates the safety perceptions of park users into the decision-making for locating facilities and services: the Recreation Opportunity Spectrum (ROS) serves as a systematic planning guide for such decision-making and is compatible with park policy and objectives. Applications to Garibaldi Provincial Park, British Columbia, and statistical and cartographic analyses of 273 questionnaires returned from there, indicate that park users’ perceptions can be advantageously incorporated into …
Scarcity-Induced Conflict: The Lebanese-Israeli Conflict Over Water, Hussein A. Amery
Scarcity-Induced Conflict: The Lebanese-Israeli Conflict Over Water, Hussein A. Amery
Theses and Dissertations (Comprehensive)
This thesis sets out to determine possible links between the depleting water resources in Israel and the country’s hegemony over the water-rich area of south Lebanon. The early Zionist and later Israeli leaders have coveted the Litani river of Lebanon, to which Israel has had access since 1978. Israel’s replenishable water stock is being fully utilized. This fact is the basis of the theoretical motif of the thesis, namely the state conflict induced by resource scarcity. Thus conflict theory is discussed and a model of conflict process is derived.
Also discussed are 1) the reasons for the high water consumption …
Oyster Spatfall In Virginia Rivers: 1986 Annual Summary, James Whitcomb
Oyster Spatfall In Virginia Rivers: 1986 Annual Summary, James Whitcomb
Reports
The Virginia Institute of Marine Science (VIMS) conducts weekly surveys from June through early October to obtain oyster spatfall information. Spat counts are made on oyster shells strung on wire and suspended from stakes on public and private beds. The number of spat on shells is counted each week of the spawning season to determine the potential of a particular area for receiving a strike and to predict the most likely period the strikes will occur.
