Описание: This edited book is devoted to environmental risk management in gas industry impacted polar ecosystems of Russia, one of the hottest topics of modern environmental science. The contributions from experts cover topics that shed new light on the impacts of oil and natural gas production on arctic ecosystems in the country as well as biogeochemical engineering technologies to manage pollution in these areas. Readers will also discover new insights on potential ecological indicators for assessing geo-environmental risks of these impacted ecosystems, and climate modeling in polar areas.
The book has interdisciplinary appeal, and specialists and practitioners in environmental sciences, ecology, biogeochemistry and those within the energy sector who are interested in understanding ecosystems affected by anthropogenic impacts in severe climatic conditions will find it particularly engaging. Through this book, readers will learn more about biogeochemical cycling through food chains and specific reactions of biota to environmental pollution in extreme environments through the lens of experts.
Описание: Here is a collection of papers from BIOGEOMON, The Fourth International Symposium on Ecosystem Behavior. The contributions address a wider-than-ever range of concerns: aspects of catchment monitoring and modeling; biogeochemistry of restored ecosystems; and the dynamics of such chemicals as mercury and phosphorous, among many other topics.
Описание: This book offers insights from a new perspective on selenium in traditional risk assessment of environmental mercury pollution at contaminated sites (and elsewhere) and related health exposure and risks.
Описание: From a new perspective, namely focusing on the interaction of selenium and mercury, this thesis provides new insights into traditional research on biogeochemical cycles of mercury in soil-plant interaction and associated human exposure and risks. The subject of this thesis is both valuable and timely, providing essential information not only on selenium-mercury interaction in the soil-plant system but also on how to assess the combined benefits and risk of co-exposure to mercury and selenium. This work also sheds light on future aspects regarding prevention, remediation and risk management for environmental mercury contamination. Presenting high-quality papers published in leading international SCI journals such as Environmental Health Perspectives and Environmental Science & Technology and having been recognized with the Special Award of Presidential Scholarship Award and Excellent Doctoral Dissertations Prize of the Chinese Academy of Sciences (CAS), this thesis offers a valuable resource for scientific communities, policy-makers and non-experts who are interested in this field. Dr. Hua Zhang works at the Norwegian Institute for Water Research (NIVA), Oslo, Norway.
Описание: Focuses on themes such as: catchment monitoring and manipulations, catchment and regional-scale modeling, nitrogen transformations and processes, and stable and radiogenic isotopes in the environment. This book also focuses on mercury and metal dynamics, phosphorus, terrestrial DOC and soil organic matter, and scaling of biogeochemical processes.
Описание: Contains reviewed papers from BIOGEOMON, the third International Symposium on Ecosystem Behavior, held at Villanova University in June 1997. This title is intended for researchers in biogeochemistry, ecosystem ecology, global change, and anthropogenic pollution, as well as to natural resource managers and policy specialists.
Описание: This book presents an intensive study on the biogeochemical cycle of mercury in a river-reservoir system in Wujiang River Basin, the upper branch of the Yangtze River. Six reservoirs located in the mainstream of the Wujiang River and their corresponding inflow/outflow rivers were selected for inclusion in this study, which was conducted by researchers from the Institute of Geochemistry, Chinese Academy of Sciences. The concentration and distribution of Hg in reservoirs (the water column, sediment, sediment pore water), inflow/outflow rivers of reservoirs, and wet deposition in Wujiang River Basin were systematically investigated, and measurements were taken of the water/air exchange flux of gaseous elemental mercury (GEM). On the basis of the data gathered, a detailed mass balance of total mercury (THg) and methylmercury (MeHg) in the six reservoirs was developed. In addition, the book identifies the primary factors controlling Hg methylation in the river-reservoir system in Wujiang River Basin. The accumulation and bio-magnification of Hg species within food chains in reservoirs and human health risk of MeHg exposure through fish consumption are also included in this book.

Описание: This book describes the interaction of greenhouse gasses with the Earth System. It takes the perspective of the Earth as an integrated system and provides examples of both changes in our current climate and those in the geological past. The book gives a required elementary description of the physics of the earth system, the atmosphere and ocean.

Описание: Nowadays, major environmental issues are the object of large public debates de- spite the fact that scientific knowledge is often insufficient to draw unequivocal conclusions. Such is the case in the ongoing debate regarding the specific contri- butions of anthropogenic greenhouse gas emissions and of natural climate changes to global warming. At least 10 to 20 years of additional observations will be re- quired, before we will be able to conclude, with certainty, on this subject. In the mean time, and as directed by their immediate interests, people will continue to promote contradictory opinions. The media are, in part, responsible for perpetuat- ing such debates in that they convey indiscriminately the opinion of highly credi- ble scientists as that of dogmatic researchers, the latter, unfortunately too often expressing working hypotheses as established facts. Naturally, in a similarly mis- informed manner, pressure groups tend to support the researcher whose opinions most closely represent either their particular ideological battles or their economic interests and, hence, in their own way, add further to the confusion and obscurity of the debate. Only a few years ago, mercury (Hg)contamination in hydroelectric reservoirs was the object of such media and social biases. At the time, analytical data used to support the discourse were themselves uncertain and numerous hypotheses, often times fanciful, were proposed and hastily "delivered" to the public.

Описание: This book provides a comprehensive review of the biogeochemistry in the Baltic Sea. It is based on the fact that biogeochemical processes that are relevant for the ecological state of the Baltic Sea (and other sea areas), are all in some way related to the production and mineralization of organic matter (biomass) and thus are associated with the consumption or release of CO2. The significant progress with regard to our chemical analytical capabilities concerning the marine CO2 system has facilitated new approaches to study the Baltic Sea biogeochemistry, in particular with regard to a quantitative process understanding. To demonstrate this, the authors present the fundamentals of the marine CO2 system in a theoretically sound, but still intelligible way. This is followed by a comprehensive presentation of our current knowledge about the CO2 system in the Baltic Sea and the implications for our understanding of biogeochemical processes such as production/mineralization of organic matter and the stoichiometry involved, nitrogen fixation, denitrification, and phosphate transformations at varying redox conditions. Finally, the CO2 gas exchange balance and related problems such as acidification are addressed.
