Introduced to the technical aspects of forestry aerial spraying in the mid-1970's, we were immediately impressed by the complexity of the process of delivering pesticide to foliage.
The increasing concern over environmental and health impact of urban air pollution has lead to a growing need for an international conference focussing specifically on urbanised regions.
The Environmental Monitoring and Assessment Program was created by EPA to develop the capability for tracking the changing conditions of our natural resources and to give environmental policy the advantages ofa sound scientific understanding of trends.
In an lUlffianaged woodland, forest development follows a succession of periods of undisturbed natural growth, interrupted by intermediate loss or damage of trees caused by fire or wind or other natural hazards.
In the summer of 1999, an international group of experts convened in Jerusalem, Israel, in order to define the major environmental challenges facing humanity at the dawn of the new millennium and - where possible - propose ways of addressing them.
Separation technologies are of crucial importance to the goal of significantly reducing the volume of high-level nuclear waste, thereby reducing the long-term health risks to mankind.
Among the many technological and legal efforts being made to restore our environment, electrostatic technologies may well hold the solution to the cleaning of air, water and soil.
The monitoring of point sources by the Environmental Protection Agency (EPA), the states, and the tribes has documented and helped reduce the levels of chemical stressors affecting our ecosystems.
This book - the first published on this topic in plants - presents the reader with an overview of recent research on nitric oxide (NO) in plants, which, in view of its empirical interest and its growth regulatory potential, is in the forefront of scientific endeavor in plant science.
More than 10 years after the "e;First European Symposium on Organic Micropollutants in the Aquatic Environment"e;, the "e;Sixth Symposium"e; was held in Lisbon (Portugal) from 22 to 24 May 1990.
The main subject of the Workshop was the new developments about the cost effective treatment techniques for better removal efftciencies and dis- cussion of policies for pollution control.
In recent decades it has become increasingly urgent to protect human health and wellbeing from the possible negative consequences of man's economic activities, both at the actual production sites and in areas where the im- pact is felt.
Sun, wind and water draining from the land interact with the morphological features of a water body to create the environment experienced by freshwater plants and animals.
Interest in the occurrence and behaviour of volatile organic compounds (VOCs) is increasing due to their adverse effects on the environment and human health.
Towards the Balance and Management of the Carbon Budget of the Biosphere The current state of misunderstanding of the global C cycle and our failure to resolve an issue that has been debated for 100 years (Jones and Henderson-Sellers, 1990) speaks loudly about the limitations of modem science when faced with the complexity of the biosphere.
Air pollution has historically been viewed as a local or regional scale problem with attention focused on acute episodes such as the sulphur dioxide and smoke smogs of London in the 1950s and 1960s and the photochemical smogs of southern California first recognized by Haagen- Smit in the early 1950s.
In 1962 Rachel Carson warned of the consequences of man's pollution in her book Silent Spring, a book that some feel marks the real beginning of our environmental awareness.
This volume contains material first presented at an international workshop on the 'Use of Microorganisms to Combat Pollution', held in Israel, May 10--18, 1992.
Ecotones, or boundary zones between land and inland waters (such as lakes, streams and rivers), are the principal routes for transport of organic matter and nutrients across landscapes via physical and biological vectors.
This Workshop was organized to assess the status of knowledge on the behaviour of phosphorus in sediments and to define gaps and reassess research strategies, particularly with respect to prevalent methodology and future approach; and to define gaps and reassess research strategies for water management measures in aquatic ecosystems, especially in relation to the release of phosphorus from the sediments and its impact on the functioning of the whole system.
Hydrometallurgy '94 contains the 78 papers that were presented at the international symposium organized by the Institution of Mining and Metallurgy and the Society of Chemical Industry and held in Cambridge, England, in July 1994.
Objectives The current global environmental crisis has reinforced the need for developing flexible mathematical models to obtain a better understanding of environmental problems so that effective remedial action can be taken.
To honour the remarkable contribution of Michel David in the inception, establishment and development of Geostatistics, and to promote the essence of his work, an international Forum entitled Geostatistics for the Next Century was convened in Montreal in June 1993.
