Air Pollution Processes in Regional Scale (NATO Science Series: IV: #30)

by Dimitrios Melas Dimiter Syrakov

An understanding of long-range transport of air pollutants in the atmosphere requires a knowledge of the relevant atmospheric dynamic and chemical processes active at the regional scale as well as the temporal and spatial distribution of emissions. Numerical modeling is the most efficient way to determine the atmospheric transport, photochemistry and deposition pathways. The book therefore discusses the physical and chemical processes that determine regional air pollution and presents the relevant modeling techniques to describe the different atmospheric processes that are active at that scale.

Air Quality and Livestock Farming (Sustainable Energy Developments)

by Thomas Banhazi Andres Aland Jörg Hartung

Air quality has a direct influence on health, welfare and production performance of livestock as the high concentrations of noxious gases, dust and airborne microorganisms are likely to reduce production efficiency and the general welfare of farm animals. Long term exposure to particulates in livestock buildings might also affect the respiratory health of farm workers. Dust in animal buildings contains many biologically active substances such as bacteria, fungi, endotoxins and residues of antibiotics (as a result of veterinary treatments) that are suspected to be hazardous to human health. Furthermore, air pollutants emitted from livestock buildings can reduce air, water and soil quality and can potentially undermine the health of nearby residents. Airborne emissions include ammonia, methane, nitrous oxide, particulates like dust and microorganisms. In addition, other potentially harmful substances such as heavy metals, antibiotic residues and components of disinfectants might be also emitted from livestock building that are potentially damaging to ecosystems. In this book, key aspects of agricultural air quality, such as monitoring, managing and reducing airborne pollutants in and around livestock facilities are reviewed. Features: addressing the raising awareness of the importance of optimal health and welfare for lifestock species with contributions from international specialists and researchers providing up-to-date information for professionals involved in modern animal producti This book will be useful for farming professionals, academics, students, policy makers, business leaders, regulatory bodies and agricultural consultants.

Air Quality in Cities

by Nicolas Moussiopoulos

Urban areas are major sources of air pollution. Pollutant emissions affecting air quality in cities are considered to have adverse consequences for human health. Public and government concern about environmental issues arising from urban air pollution has increased over the last decades. The urban air pollution problem is widespread throughout the world and it is important to find ways of eliminating or at least reducing the risks for human health. The fundamentals of the physical and chemical processes occurring during air pollutant transport in the atmosphere are nowadays understood to a large extent. In particular, modelling of such processes has experienced a remarkable growth in the last decades. Monitoring capabilities have also improved markedly in the most urban areas around the world. However, neither modelling nor monitoring can solve urban air pollution problems, as they are only a first step in improving useful information for future regulations. The defining of efficient control strategies can­ not be achieved without a clear knowledge of the complete pollution process, i.e. emission, atmospheric transport and transformation, and deposition at the receptor. Improving our ability to establish valid urban scale source-receptor relation­ ships has been the objective of SA TURN, one of the 14 subprojects of EURO­ TRAC-2. Similar to the other subprojects of this co-ordinated environmental pro­ ject within the EUREKA initiative, SA TURN brought together international groups of scientists to work on problems directly related to atmospheric chemistry and physics. The present volume summarises the scientific results of SATURN.

Air Quality in the Mexico Megacity: An Integrated Assessment (Alliance for Global Sustainability Bookseries #2)

by Mario J. Molina Luisa T. Molina

In this book, experts in atmospheric sciences, human health, economics, social and political sciences contribute to an integrated assessment of the complex elements needed to structure air quality policy in the 21st century. The analysis is developed through a case study of the Mexico City Metropolitan Area - one of the world's largest megacities in which air pollution grew unchecked for decades. The international research team is led by Luisa T. and Mario J. Molina, Nobel Laureate in Chemistry. Improvements in Mexico City's air quality in the last decade testifies to the power of determined and enlightened policy making, and throws into relief the tough problems that remain to be solved.The volume's first six chapters, including the contributions of over 50 distinguished scholars from Mexico and the US, outline the fundamental areas of knowledge policy makers must accommodate. The message is that only good science and well-chosen technologies can direct the way to corrective regulatory measures; but without strong commitment from government, no amount of science or technology can help.

Air Sampling and Industrial Hygiene Engineering

by Martha J. Boss Dennis W. Day

We know certain chemicals cause problems in the workplace. The issues now are: Where do they occur in the workplace? How can we best evaluate them? What are the procedures for dealing with them safely? Many books simply define the problem and tell you that you need a program. Air Sampling and Industrial Hygiene gives you a guide to air sampling protocols from start to finish. The book presents sampling technology updated with today's tools - such as microcircuitry and remote sensing. The authors emphasize an interdisciplinary approach to understanding how air monitoring can adequately report current environmental conditions associated with outdoor media, indoor remediation efforts, proximal equipment, interior line monitoring, and the interrelationship of ventilation parameters. In addition to providing the how-tos of sampling, this guide covers the basics of chemical risk assessment, biological assessment, engineering evaluation of mechanical system design criteria, and chemical or process engineering hazard assessments. It presents the information using text, text outlines, graphics, and pictures - including cross sections of instrumentation and side bars to elaborate on complex concepts.Faulty readings caused by poor sampling techniques can be very costly. This book provides the how-tos for making design engineering and on-site decisions as to instrumentation selection and scheduled usage. Air Sampling and Industrial Hygiene Engineering will allow you to complete the sampling process systematically and correctly from initial suspicions to the use of obtained results.

Air-Sea Exchange of Heat and Moisture During Storms (Atmospheric and Oceanographic Sciences Library #10)

by R.S. Bortkovskii

Scientists investigating the interaction between the ocean and the atmosphere now believe that the drag coefficient, and the coefficients of heat transfer and moisture transfer at the sea surface, all increase with an intensification of the wind, reaching high values during a storm. This belief is based on the results of gradient and eddy correlation measurements in the air layer over the water, as weIl as on data concerning the effect of storms on the structure of the upper layer of the ocean and on the planetary atmospheric boundary layer. However, until recently it was impossible to explain just how the above coefficients depend on the wind velocity and to extrapolate this dependence into the region of hurricane velocities. Only by studying nonturbulent mechanisms of transfer, which play an important role dose to the surface of a stormy sea, and mechanisms of spray­ mediated transfer in particular, was it possible to proceed to a solution of this problem. This book presents the results of laboratory and field studies of the spray field in the air layer above the surface of a stormy sea. Since there is a dose correlation between the generation of spray and the breaking of wind waves, considerable attention is given to the analysis of data on the sea state during a storm. Su'ch data are of interest when solving a number of diverse theoretical and applied problems.

Air-Sea Exchange: Physics, Chemistry and Dynamics (Atmospheric and Oceanographic Sciences Library #20)

by G. L. Geernaert

During the 1980's a wealth of information was reported from field and laboratory experiments in order to validate andlor modify various aspects of the surface layer Monin-Obukhov (M-O) similarity theory for use over the sea, and to introduce and test new concepts related to high resolution flux magnitudes and variabilities. For example, data from various field experiments conducted on the North Sea, Lake Ontario, and the Atlantic experiments, among others, yielded information on the dependence of the flux coefficients on wave state. In all field projects, the usual criteria for satisfying M-O similarity were applied. The assumptions of stationarity and homogeneity was assumed to be relevant over both small and large scales. In addition, the properties of the outer layer were assumed to be "correlated" with properties of the surface layer. These assumptions generally required that data were averaged for spatial footprints representing scales greater than 25 km (or typically 30 minutes or longer for typical windspeeds). While more and more data became available over the years, and the technology applied was more reliable, robust, and durable, the flux coefficients and other turbulent parameters still exhibited significant unexplained scatter. Since the scatter did not show sufficient reduction over the years to meet customer needs, in spite of improved technology and heavy financial investments, one could only conclude that perhaps the use of similarity theory contained too many simplifications when applied to environments which were more complicated than previously thought.

Air-Sea Interaction: Instruments and Methods

by F. Dobson L. Hasse R. Davis

During the past decade, man's centuries-old interest in marine me­ teorology and oceanography has broadened. Ocean and atmosphere are now treated as coupled parts of one system; the resulting interest in air-sea interaction problems has led to a rapid growth in the sophistication of instruments and measurement techniques. This book has been designed as a reference text which describes, albng with the instruments themselves, the accumulated practical experi­ ence of experts engaged in field observations of air-sea interac­ tions. It is meant to supplement rather than replace manuals on standard routine observations or instnunentation handbooks. At the inception a textbook was planned, which would contain only well tested methods and instruments. It was quickly discovered that for the book to be useful many devices and techniques would have to be included which are still evolving rapidly. The reader is therefore cautioned to take nothing in these pages for granted. Certainly, every contributor is an expert, but while some are back­ ed up by generations of published work, others are pioneers. The choice of topics, of course, is debatable. The types of observa­ tions included are not exhaustive and topics such as marine aero­ sols and radio-tracers are omitted, as was the general subject of remote sensing, which was felt to be too broad and evol ving too rapidly. The guideline adopted in limiting size was maximum use­ fulness to 'a trained experimentalist new to the field'.

Air Survey of Sand Deposits by Spectral Luminance

by Mariya A. Romanova

This book gives an account of a method of determining the type composition of sandy deposits from the air by the nature of their reflection of radiant energy. The measured spectral luminance of a rock outcrop rela­ ti ve to the luminance of a standard is the basic property considered in this method. The spectral luminance factors p\ are measured by means of special instruments - a universal photometer, cinespectrograph, spectro­ visors, and other spectrometers. The measured values of P" of the investigated rocks are interpreted geologically with the aid of some methods of mathematical statistics so that a means of lithological mapping of sandy deposits from the air can be found. The importance of developing a method of determining the type composition of rocks, primarily sandy de­ posits, from the air stems from the extensive occurrence of deserts on the earth's surface. Sandy deserts occupy vast areas in the southern latitudes of the USSR and occur in western and central China, Pakistan, Iran, India, and other states. In these deserts there are numerous deposits of petroleum and gas, and a search for water is continuously in progress. Successful prospecting for the above minerals depends on a determination of the material composition of the sandy deposits in these deserts and the solution of several questions of recent tec­ tonics, paleogeography, and quaternary geology, the answers to which might also be given by a study of the dis­ tribution of lithological types of sands.
