This book was released on 2012-10-17 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most impressive large rivers worldwide is in Egypt the river Nile known since ages for its intense anthropogenic use as well as for increasing pollution along its course from spring to estuary forming presumably a strong gradient of pollutants. Effective management of the river Nile in a manner that supports a sustainable economy and society with sufficient quantity and quality of water is essential. In order to do this, however, improved water quality monitoring is necessary to facilitate resource protection and to understand ecological changes within ecosystems. In past decades, aquatic monitoring programs dealt only with the measurement of physical and chemical variables. Physicochemical analyses alone are insufficient to provide the information about water quality and it is essential to use biological test systems (biomonitoring) with living cells or organisms that provide a general response to the pollutants present in the sample. Biomonitoring takes advantage of the knowledge that chemicals that have entered the organisms leave biomarkers reflecting this exposure. Biomarkers have been proposed as sensitive tools for detecting environmental exposure and adverse effects of toxic anthropogenic chemicals on aquatic organisms. Biomarkers may take many forms - from the assessment of chemical residues in the tissues of living organisms (bioaccumulation level), through to assaying specific biological end points based on changes to various biochemical, physiological, morphological or behavioral characteristics in organisms, as well as traditional ecological community attributes such as abundance and diversity. Biomarkers at the molecular level tend to respond first, followed by responses at the cellular (biochemical), morphological/histological and whole-body levels. Thus, by monitoring molecular, biochemical and physiological parameters biomarkers can be used as an early warning system and the potential harm of an agent can be assessed before more severe disturbances/consequences occur. Within this book, in the interest of clarity, the early warning biomarkers are limited as “rapidly-responding biomarkers” to the sub-organismic changes, such as bioaccumulation biomarkers, molecular biomarkers, biochemical biomarkers, physiological biomarkers, and morphological/histological biomarkers, that can be measured in cells, body fluids, tissues or organs within an organism and are indicative of xenobiotic exposure and/or effect.

Download or read book Fundamentals of Tropical Freshwater Wetlands written by Tatenda Dalu and published by Elsevier. This book was released on 2021-11-25 with total page 864 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Tropical Freshwater Wetlands: From Ecology to Conservation Management is a practical guide and important tool for practitioners and educators interested in the ecology, conservation and management of wetlands in tropical/subtropical regions. The book is written in such a way that, in addition to scientists and managers, it is accessible to non-specialist readers. Organized into three themed sections and twenty-three chapters, this volume covers a variety of topics, exposing the reader to a full range of scientific, conservation and management issues. Each chapter has been written by specialists in the topic being presented. The book recognizes that wetland conservation, science and management are interlinked disciplines, and so it attempts to combine several perspectives to highlight the interdependence between the various professions that deal with issues in these environments. Within each chapter extensive cross-referencing is included, so as to help the reader link related aspects of the issues being discussed. Contributed to by global experts in the field of tropical wetlands Includes case studies and worked examples, enabling the reader to recreate the work already done Focuses on tropical systems not available in any other book

Download or read book Chemical Biomarkers in Aquatic Ecosystems written by Thomas S. Bianchi and published by Princeton University Press. This book was released on 2011-02-28 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook provides a unique and thorough look at the application of chemical biomarkers to aquatic ecosystems. Defining a chemical biomarker as a compound that can be linked to particular sources of organic matter identified in the sediment record, the book indicates that the application of these biomarkers for an understanding of aquatic ecosystems consists of a biogeochemical approach that has been quite successful but underused. This book offers a wide-ranging guide to the broad diversity of these chemical biomarkers, is the first to be structured around the compounds themselves, and examines them in a connected and comprehensive way. This timely book is appropriate for advanced undergraduate and graduate students seeking training in this area; researchers in biochemistry, organic geochemistry, and biogeochemistry; researchers working on aspects of organic cycling in aquatic ecosystems; and paleoceanographers, petroleum geologists, and ecologists. Provides a guide to the broad diversity of chemical biomarkers in aquatic environments The first textbook to be structured around the compounds themselves Describes the structure, biochemical synthesis, analysis, and reactivity of each class of biomarkers Offers a selection of relevant applications to aquatic systems, including lakes, rivers, estuaries, oceans, and paleoenvironments Demonstrates the utility of using organic molecules as tracers of processes occurring in aquatic ecosystems, both modern and ancient
