Asadi and published by Laxmi Book Publication. This book was released on 2023-11-18 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: The properties of sediment particles, transportation and their deposition in the sedimentary environments can be deciphered by the granumlometric studies, which also provide critical information regarding sedimentary provenance and depositional conditions. Many factors like currents and wave activities, offshore and onshore movements, transgression and regression of the sea levels, periodic storms, confluence of streams, rivulets and rivers into the oceans can influence the grain size in the depositional environments. Variations in the size of the grains reflect various earth surface processes viz., developmental processes of landforms. So, many researchers from all over the world carried out panoptic research and emphasized the significance of granulometric analysis to understand and to distinguish various depositional environments viz., estuarine, lacustrine, fluvial and marine etc., in particular in the coastal realms.
Download or read book Environmental Remediation Technologies for Metal Contaminated Soils written by Hiroshi Hasegawa and published by Springer. This book was released on 2015-10-08 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive and detailed description of remediation techniques for metal-contaminated soils derived from both natural processes and anthropogenic activities. Using a methodical, step-by-step presentation, the book starts by overviewing the origin of toxicants and the correlated comparative extent of contamination to the environment. The legal provisions as proposed or applied in different countries are then discussed to explain the global regulatory situation regarding soil contamination and the extent of consequent concern. The core part of this publication describes the major techniques for in situ or ex situ treatment of the contaminated soil to meet the regulatory limits. Finally, risk evaluation is incorporated, giving special attention to possible impacts during or after implementation of the remediation strategies. The intrusion of metals in soils mostly occurs from various anthropogenic activities, e.g., agricultural practices, industrial activities, and municipal waste disposal. The volumes of metal-contaminated soil are becoming greater than before and are ever-increasing due to rapid urbanization, intensified industrialization, and/or population booms in certain parts of the world. Hence, the options previously proposed, such as isolation of the contaminated site or movement of the contaminated mass to a secure disposal site after excavation, are becoming unsuitable from the economic point of view, and instead, decontamination alternatives are preferred. This book will help readers such as scientists and regulators to understand the details of the remediation techniques available to deal with the soils contaminated by toxic metals.

Available in PDF, EPUB and Kindle. Book excerpt: Wetlands Conservation An up-to-date overview of approaches for addressing wetlands degradation and its effects on ecosystem services, human health, and other ecosystems Wetlands are essential sources of biodiversity, water purification, groundwater replenishment, flood control, storm protection, sediment retention, recreation and tourism, and more. Human exploitation of natural resources over the past 200 years has caused significant wetlands degradation and loss. Although the Ramsar Convention of 1971 drafted polices for wetland conservation and responsible use, many wetland sites remain inadequately conserved or managed. Maintaining the ecological balance and equilibrium of wetlands requires a clear understanding of the vital role of wetlands, the difficulties they face, and the policies enacted for their protection. Wetlands Conservation: Current Challenges and Future Strategies summarizes both current and emerging management strategies, trends, and policies regarding wetlands protection around the world. The authors provide accurate scientific information on wetlands while discussing the effects of climate change, global warming, modernization in agriculture, and other key topics. Designed to assist in the development of future solutions for wetlands conservation and management strategies, this important volume: Highlights the environmental, socioeconomic, and cultural importance of wetlands Identifies the factors responsible for the failure of many conservation initiatives Describes the natural and anthropogenic factors of wetlands degradation Discusses the role of community-based wetlands conservation and management Explores Ramsar wetlands conservation and its impacts worldwide Wetlands Conservation: Current Challenges and Future Strategies is an invaluable resource for graduate and postgraduate students, researchers, ecologists, policymakers, conservation organizations, and others working in the field of natural resources management.

Download or read book Monitoring of Marine Pollution written by Houma Bachari Fouzia and published by BoD – Books on Demand. This book was released on 2019-06-05 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many of the pollutants discharged into the sea are directly or indirectly the result of human activities. Some of these substances are biodegradable, while others are not. This study is devoted to monitoring areas of the environment. Methods assessment is based on monitoring data and an evaluation of the impact of pollution.Surveillance provides a scientific basis for standards development and application. The methodology of marine pollution control is governed by algorithms and models. A monitoring strategy should be put in place, coupled with an environmental assessment concept, through targeted research activities in areas identified at local and regional levels. This concept will make it possible to diagnose the state of "health" of these zones and consequently to correct any anomalies. Monitoring of the marine and coastal environment is based on recent methods and validated after experiments in the field of marine pollution.

Download or read book Sediment Provenance Studies in Hydrocarbon Exploration and Production written by R.A. Scott and published by Geological Society of London. This book was released on 2014-06-25 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sediment provenance studies concern the origin, composition, transportation and deposition of detritus and therefore are an important part of understanding the links between basinal sedimentation, and hinterland tectonics and unroofing. Such studies can add value at many stages of hydrocarbon exploitation, from identifying regional-scale crustal affinities and sediment dispersal patterns during the earliest stages of exploration, to detailed correlation in producing reservoirs and understanding the impact of mineralogy on reservoir diagenesis. The volume showcases the wide variety of techniques available, using examples and applications from all aspects of sediment provenance research. The papers are organized into four sets around the following themes: • Overview: applications of provenance information in hydrocarbon reservoir sandstones • Provenance, diagenesis and reservoir quality • Provenance studies linking sediment to source • Looking forward: development of techniques and data handling This book is dedicated to the memory of Maria Mange and Robert A. Scott.

Download or read book Trace Metals in a Tropical Mangrove Wetland written by Santosh Kumar Sarkar and published by Springer. This book was released on 2017-08-09 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive and accessible guide covering various aspects of trace metal contamination in abiotic and biotic matrices of an iconic Indian tropical mangrove wetland – Sundarban. Divided into nine chapters, the book begins by discussing the fundamental concepts of sources, accumulation rate and significance of trace metal speciation, along with the impact of multiple stressors on trace metal accumulation, taking into account both tourist activities and the exacerbating role of climate change. The second chapter presents a detailed account of the sampling strategy and preservation of research samples, followed by exhaustive information on sediment quality assessment and ecological risk, instrumental techniques in environmental chemical analyses, quality assurance and quality control, along with the Sediment Quality Guidelines (SQGs). Using raw data, the sediment quality assessment indices (e.g., pollution load index, index of geoaccumulation, Nemerow Pollution Load Index etc.) and conventional statistical analyses are worked out and interpreted precisely, allowing students to readily evaluate and interpret them. This is followed by chapters devoted to trace metal accumulation in sediments and benthic organisms, as well as acid-leachable and geochemical fractionation of trace metals in sediments. The book then focuses on chemical speciation of butylin and arsenic in sediments as well as macrozoobenthos (polychaetous annelids). Finally, potential positive role of the dominant mangrove Avicennia in sequestering trace metals from rhizosediments of Sundarban Wetland is elaborately discussed. This timely reference book provides a versatile and in-depth account for understanding the emerging problems of trace metal contamination – issues that are relevant for many countries around the globe.

Download or read book Marine Pollution Monitoring Management and Mitigation written by Amanda Reichelt-Brushett and published by Springer Nature. This book was released on 2023-05-11 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of marine environments inevitably involves considering the problem of marine pollution, which includes questions that focus on the essential need to ensure the long-term health of these exceptional ecosystems and the lives and livelihoods they support. The open access textbook "Marine Pollution: monitoring, management and mitigation" approaches these questions in a practical and highly readable format. It gives newcomers to the field background and perspective through the first comprehensive, multidisciplinary exploration of the topic. The topic is indeed complex, requiring the integration of the natural sciences and chemistry with management, policymakers, industry and all of us who are users of the marine environment. The textbook was written by leading experts to especially prepare graduates for a career in marine pollution studies. At the same time, it is relevant for anyone invested in the marine environment with a will to reduce their impacts. The chapters can easily be used independently and are also connected through the cross-referencing of related content. The introductory chapter provides a historical account of marine pollution and explores the fundamental physicochemical conditions of seawater. Two full chapters cover the requisite resources for ensuring success in field and laboratory studies. Then, chapter by chapter the book dives into to the various types of marine pollutants. In closing, it discusses the challenges of understanding multiple stressors and presents mitigation and restoration practices, along with a global overview of marine pollution legislation. We envisioned this textbook as being open access for the very reason we created it: this topic calls for global contributions and champions, and financial restraints should not limit access to this knowledge.

This book was released on 2012-12-06 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Joint Commission (IJC) was established between Canada and the United States under the Boundary Water Agreement in 1909. The Great Lakes Water Quality Agreement between the two countries (signed in 1972, revised and renewed in 1978) expresses the determination of each country to restore and en hance the water quality of the largest freshwater system in the world. The Agreement provides for two inter national boards to assist the IJC: the Great Lakes Water Quality Board and the Great Lakes Science Advisory Board. In 1982, the Dredging Subcommittee of the Great Lakes Water Quality Board was asked to investigate and provide an assessment of the environmental impacts of sediment-bound contaminants and to recom mend alternate strategies for solving ecological problems associated with the presence and removal of pollu tants. This issue however, was beyond the scope of the Dredging Subcommittee. It was then referred to the Great Lakes Science Advisory Board with a specific request that the Board focus on whether contaminated sediments located in areas with water quality problems and impaired uses should be removed and if so, under what conditions. The Science Advisory Board established a Task Force to address these issues with specific reference to: - provide the IJC with an assessment of the effects of sediment-bound contaminants on biota and water quality; - recommend appropriate remedies for possible application by the parties for remedial activities in the Great Lakes; and - identify gaps in knowledge and suggest appropriate investigations to provide this knowledge.
