Emission inventory is basic for the understanding of environmental behaviors and potential effects of compounds, however, current inventories are often associated with relatively high uncertainties. One important reason is the lack of emission factors (EFs), especially for the residential solid fuel combustion in developing countries. In the present study, emission factors of a group of pollutants including particulate matter, organic carbon, elemental carbon (sometimes known as black carbon) and polycyclic aromatic hydrocarbons were measured for a variety of residential solid fuels including coal, crop straw, wood, and biomass pellets in rural China. The study provided a large number of emission factors that can be further used in emission estimation. Composition profiles and isomer ratios were investigated and compared so as to be used in source apportionment. In addition, the present study identified and quantified the influence of factors like fuel moisture, volatile matter on emission performance. The publication of the study will be of interest and helpful to the readers in the field of air pollution, human health, fuel saving and energy consumption etc. Guofeng Shen works at the Institute of Atmospheric Sciences, Jiangsu Academy of Environmental Sciences, China.

This volume describes what is arguably the first and only valuation study to meet in full the reference study standards set by NOAA's Blue Ribbon Panel on Contingent Valuation. This book documents a contingent valuation study for a generic environmental good: preventing the likely injuries from oil spills on the coast of Central California. It provides a wealth of materials which will reduce the long lead time which characterizes most economic damage assessments. This is achieved by so richly documenting the design, administration, and analysis of such studies as to be effectively a 'how-to' guide for undertaking state-of-the-art contingent valuation studies. The book is supported by a CD-ROM containing a wealth of additional material, including data, questionnaires, and transcripts. Together, they constitute a unique and vital contribution to the literature concerning the valuation of non-market preferences.

This book addresses the synthesis of photosensitizers, the main emphasis being on the new methods of synthesis such as microwave, sonochemistry and the use of ionic liquids.

Many large mathematical models, not only models arising and used in environmental studies, are described by systems of partial differential equations. The discretization of the spatial derivatives in such models leads to the solution of very large systems of ordinary differential equations. These systems contain many millions of equations and have to be handled over large time intervals by applying many time-steps (up to several hundred thousand time-steps). Furthermore, many scenarios are as a rule to be run. This explains the fact that the computational tasks in this situation are enormous. Therefore, it is necessary to select fast numerical methods; to develop parallel codes and, what is most important when the problems solved are very large to organize the computational process in a proper way.
The last item (which is very often underestimated but, let us re-iterate, which is very important) is the major topic of this book. In fact, the proper organization of the computational process can be viewed as a preparation of templates which can be used with different numerical methods and different parallel devices. The development of such templates is described in the book. It is also demonstrated that many comprehensive environmental studies can successfully be carried out when the computations are correctly organized. Thus, this book will help the reader to understand better that, while (a) it is very important to select fast numerical methods as well as (b) it is very important to develop parallel codes, this will not be sufficient when the problems solved are really very large. In the latter case, it is also crucial to exploit better the computer architecture by organizing properly the computational process.
- Use of templates in connection with the treatment of very large models
- Performance of comprehensive environmental studies
- Obtaining reliable and robust information about pollution levels
- Studying the impact of future climatic changes on high pollution levels
- Investigating trends related to critical levels of pollution

The new fifth edition of Ecotourism focuses on an array of economic, social and ecological inconsistencies that continue to plague ecotourism in theory and practice, and examines the sector in reference to other related forms of tourism, impacts, conservation, sustainability, education and interpretation, policy and governance, and the ethical imperative of ecotourism as these apply to the world's greenest form of tourism. Building on the success of prior editions, the text has been revised throughout to incorporate recent research, including ecotourism taking place in under-represented world regions. It includes new case studies on important themes in research and practice as well as learning objectives in each chapter. David Fennell provides an authoritative and comprehensive review of the most important issues, including climate change and UN Sustainable Development Goals. Ecotourism continues to be embraced as the antithesis of mass tourism because of its promise of achieving sustainability through conservation mindedness, community development, education and learning, and the promotion of nature-based activities that are sensitive to both ecological and social systems. The book debates to what extent this promise has been realised. An essential reference for those interested in ecotourism, the book is accessible to students, but retains the depth required for use by researchers and practitioners in the field. This book will be of interest to students across a range of disciplines including geography, economics, business, ethics, biology, and environmental studies.

Environmental forensics is the application of scientific techniques for the purpose of identifying the source and age of a contaminant. Over the past several years, this study has been expanding as a course of study in academia, government and commercial markets. The US Environmental Protection Agency (EPA), Federal Bureau of Investigation (FBI), and Federal Emergency Management Agency (FEMA) are among the governmental agencies that utilize the study of environmental forensics to ensure national security and to ensure that companies are complying with standards. Even the International Network for Environmental Compliance and Enforcement (INECE), a group supported by the European Commission and the World Bank, utilizes the study of environmental forensics as it applies to terror threats.
This title is a hands-on guide for environmental scientists, engineers, consultants and industrial scientists to identify the origin and age of a contaminant in the environment and the issues involved in the process. An expansion of the authors' first title with Academic Press, "Introduction to Environmental Forensics," this is a state-of-the-art reference for those exploring the scientific techniques available.

There is widespread public concern about hazardous chemicals that are contained in air, soil, water and food. Policy has therefore adopted a series of laws and regulations concerning emissions into and concentration levels in different media including food. As policy makers do not only have to consider the protection of the environment but also need to ensure a well-functioning economy at the same time, these limit or target values need to be set in a balanced way. The main problem, however, is to compare the costs for achieving these targets with the benefits to society by having a smaller exposure to hazardous substances (cost-benefit analysis).

This book sets out to improve the reliability of cost-benefit analyses particularly of hazardous substances present in air, water, soil and food. It suggests that the human health risk assessment of chemicals is performed in a bottom-up analysis, i.e., following a spatially resolved multimedia modelling approach. In order to support cost-benefit analyses, the approach is accompanied by monetary valuation of human health impacts, yielding so-called external costs. Results for selected priority metals show that these external costs are small compared to those by the classical air pollutants and involve rather long time horizons touching on the aspect of intergenerational equity within sustainable development. When including further hazardous substances, the total external costs attributable to contaminants are expected to be more substantial.

sector. This ensured eventual transfer of the technology demonstrated at the wo- shops and Technical Meetings to marketable devices. BIOSET provided assistance for researchers from European laboratories to meet to exchange ideas, use equ- ment, and establish a basis for new joint projects. The secretariat of the Concerted Action BIOSET supported the Technical Meetings. There were three Technical Meetings held, two in Berlin in 1997 and 1998, and the third in Barcelona, in April 2000. The goal of these technical meetings was to join different research and industrial teams to evaluate the performance of their biosensor technology in field conditions with common and standardized surface and waste waters. As a result of these field experiments, the additional information that biosensors can offer to environmental monitoring was also evaluated. Thus, these three Technical Meetings were useful accompanying measures and practical additions to the currently organized yearly workshops. The concerted action BIOSET was f- lowed by the SENSPOL network. The 1st SENSPOL Workshop was held on the 9-11 May 2001 on Sensing Technologies for Contaminated Sites and Groundwater at the University of Alcala. There was one special Workshop on "Genotoxicity Biosensing (TECHNOTOX)" supported by the European Commission DG XII D-1 and BIOSET in the year 2000. The TECHNOTOX meeting at the Flemish Institute for Technological Research (VITO) in Mol was organized by Phillippe Corbisier (VITO), Peter-D. Hansen (TU Berlin) and Damia Barcelo (CSIC Barcelona).

Throughout the world's arid regions, and particularly in northern and eastern Africa, formerly nomadic pastoralists are undergoing a transition to settled life. Pastoral sedentarization represents a response to multiple factors, including loss of livestock due to drought and famine, increased competition for range land due to growing populations, land privatization or appropriation for commercial farms, ranches, and tourist game parks, and to fear of increasing violence, ethnic conflict, and civil war. Although pastoral settlement is often encouraged by international development agencies and national governments as solutions to food insecurity, poor health care and problems of governance, the social, economic and health concomitants of sedentism are not inevitably beneficial. Biosocial studies presented in this volume, for example, point to greater nutritional and health benefits among nomadic livestock keepers, but increased opportunities in education, employment, and food security in towns.
This book examines from an interdisciplinary perspective pastoral sedentarization in one region of Africa - Marsabit District in northern Kenya - an isolated and arid region bordering Ethiopia and which contains multiple pastoral groups including Rendille, Samburu, Ariaal, Borana and Gabra peoples. Within this locale, we present recent studies conducted by cultural and biological anthropologists, veterinary biologists, economists, geographers and medical and community health personnel, linked by the common goal of delineating the consequences, both positive and negative, of settlement for formerly nomadic pastoral populations. For many of these former pastoralists, settled life does notnecessarily constitute a break with their pastoral kin and neighbors, but represents one more opportunity with which to survive in a difficult physical and social environment.
This edited work is a collection of international contributors from North America, Africa and Europe and focuses on a dilemma that affects many parts of the indigenous world.

This book presents the proceedings and the outcomes of the NATO Advanced Research Workshop (ARW) on Integrated Technologies for Environmental Monitoring and Information Production, which was held in Marmaris, Turkey, between September 10- 14, 200 I. With the contribution of 45 experts from 20 different countries, the ARW has provided the opportunity to resolve the basic conflicts that tend to arise between different disciplines associated with environmental data management and to promote understanding between experts on an international and multidisciplinary basis. The prevailing universal problem in environmental data management (EDM) systems is the significant incoherence between data collection procedures and the retrieval of information required by the users. This indicates the presence of problems still encountered in the realization of; (1) delineation of objectives, constraints, institutional aspects of EDM; (2) design of data collection networks; (3) statistical sampling; (4) physical sampling and presentation of data; (5) data processing and environmental databases; (6) reliability of data; (7) data analysis and transfer of data into information; and (8) data accessibility and data exchange at local, regional and global scales. Further problems stem from the lack of coherence between different disciplines involved in EDM, lack of coordination between responsible agencies on a country basis, and lack of coordination on an international level regarding the basic problems and relevant solutions that should be sought.

Nitrous oxide gas is a long-lived relatively active greenhouse gas (GHG) with an atmospheric lifetime of approximately 120 years, and heat trapping effects about 310 times more powerful than carbon dioxide per molecule basis. It contributes about 6% of observed global warming. Nitrous oxide is not only a potent GHG, but it also plays a significant role in the depletion of stratospheric ozone. This book describes the anthropogenic sources of N2O with major emphasis on agricultural activities. It summarizes an overview of global cycling of N and the role of nitrous oxide on global warming and ozone depletion, and then focus on major source, soil borne nitrous oxide emissions. The spatial-temporal variation of soil nitrous oxide fluxes and underlying biogeochemical processes are described, as well as approaches to quantify fluxes of N2O from soils. Mitigation strategies to reduce the emissions, especially from agricultural soils, and fertilizer nitrogen sources are described in detail in the latter part of the book.

For the past 3.8 billion years, the geochemistry of the Earth's surface - its atmosphere, waters and exposed crust - has been determined by the presence of biota. Photosynthetic organisms exposed the Earth's surface to oxygen, denitrifying bacteria have maintained the nitrogen concentration in Earth's atmosphere, and land plants have determined the rate of chemical weathering. Life determines the global biogeochemical cycles of the elements of biochemistry, especially C, N, P and S. Volume 8 traces the origin and impact of life on the geochemistry of the Earth's surface, with special emphasis on the current human impact on global biogeochemical cycles.
