Download or read book Sediment Quality Assessment written by Graeme Batley and published by CSIRO PUBLISHING. This book was released on 2016-02-01 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contaminated sediments represent an ongoing threat to the health of aquatic ecosystems. The assessment of sediment quality is, therefore, an important concern for environmental regulators. Sediment quality guidelines are now well established in regulatory frameworks worldwide; however, practical guidance that covers all of the key aspects of sediment quality assessment is not readily available. In 2005, CSIRO published its highly cited Handbook for Sediment Quality Assessment. In the ensuing period, the science has advanced considerably. This practical guide is a revised and much expanded second edition, which will be a valuable tool for environmental practitioners. Written by experts in the field, it provides coverage of: sediment sampling; sample preparation; chemical analysis; ecotoxicology; bioaccumulation; biomarkers; and ecological assessment. In addition, detailed appendices describe protocols for many of the tests to be used.

Download or read book PAHs written by Peter E. T. Douben and published by John Wiley & Sons. This book was released on 2003-07-25 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polycyclic aromatic hydrocarbons (PAHs), or polyarenes, are one of the largest and most structurally diverse class of organic molecules known. High percentages of polyarenes, representing a wide range of molecular sizes and structural types, are present in coal tars and petroleum residues. The major sources of PAHs are crude oil, coal and oil shale. The fuels produced from these fossil sources constitute the primary source of energy for the industrial nations of the world, and the petrochemicals from these raw materials are the basis of the synthetic fibre and plastics industries. PAHs are however, widespread pollutants and their impact on the environment and human health must be monitored and controlled. This book will review and assess our scientific understanding of the ecological exposure and effects PAHs have in different environments and habitats. It will accomplish this by taking the recipients of the pollution in the environment as starting points and working its way back through pathways to access what is required for our understanding of effects and rationale for control. Although this book will concentrate on ecological exposure of PAHs, the general impacts of PAHs on human populations will be touched upon. It is thought to be the first book to focus on the ecological aspects of PAHs.

This book was released on 2012 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: The St. Lawrence River is subject to various anthropological pressures that can entail negative consequences for the ecosystem. As a result of the third and fourth St. Lawrence Action Plans, the current vision of sustainable management of this river and its main functions emphasizes the need for sound risk-based assessment approaches to support management decisions. More specifically, the sustainable navigation strategy, drawn up under St. Lawrence Action Plan III, explicitly identifies the need to develop sediment quality assessment tools, including those derived from ecotoxicological studies. The first management option addressed in this perspective was the open-water disposal of dredged sediments. In this context, an ecotoxico-logical risk assessment (ERA) approach using chemical characterization in Tier 1 and benthic organisms' toxicity tests in Tier 2 was elaborated based on physicochemical, toxicity testing, and benthic community structure data acquired from sediment samples collected in 59 sites along the St. Lawrence River. Hence this ERA approach will be used to determine whether the risk posed by the exposure of benthic organisms to dredged sediments at deposit sites and downstream is acceptable and compatible with open-water disposal.
Download or read book Contaminated Rivers written by Jerry R. Miller and published by Springer Science & Business Media. This book was released on 2007-05-06 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an introductory understanding of fluvial geomorphic principles and how these principles can be integrated with geochemical data to cost-effectively characterize, assess and remediate contaminated rivers. The book stresses the importance of needing to understand both geomorphic and geochemical processes. Thus, the overall presentation is first an analysis of physical and chemical processes and, second, a discussion of how an understanding of these processes can be applied to specific aspects of site assessment and remediation. Such analyses provide the basis for a realistic prediction of the kinds of environmental responses that might be expected, for example, during future changes in climate or land-use.

Available in PDF, EPUB and Kindle. Book excerpt: There is not an extensive literature on street sweeping. Much of the research that has been completed exists in the "gray" area of technical reports and government documents. Furthermore, a great deal of this research is locally based, and has not been widely published. Indeed, our review of the scientific literature, revealed that, while storm water quality has received a lot of attention, few academicians have been involved in street sweeping research per se. Thus, throughout our research into street we sweeper effectiveness, sweeping protocols, and sweeping practices, wished that there had been a book summarizing some of the important issues associated with street sweeping. As our frustration grew, we realized that we were uniquely poised to write such a book as our research had encompassed a variety of different projects including sweeper testing, waste management, and related storm water quality. Also, early on in this exercise, we recognized that there was a growing demand for information about street sweeping policies and management, especially for studies focusing on the effectiveness of different sweeping schedules, on waste management operations, and on non-point, pollution reduction practices associated with storm water runoff. It was abundantly clear that there was a profound lack of research on street sweeping that could assist with developing local, regional, or national policies. There was, in effect, little guidance for city managers on these issues.
Download or read book Screening Guide for Contaminated Sediment Treatment Technologies written by and published by . This book was released on 1993 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guide describes contaminated sediment treatment scenarios (with variants) available to project promoters: everything from no action to partial or total removal of sediment contaminants, depending on the decontamination level required by current criteria. The strengths and limitations of each scenario are outlined, and scenario evaluation and selection criteria are proposed. Pretreatment technologies are described, and each's stage of development, strengths and limitations are indicated. Soil and sediment treatment technologies tested in different parts of the world or under demonstration for sediment remediation are described. For each type of technology, the following information is given: basic principle, methods or processes available, application, strengths and limitations, processes demonstrated on sediment processes under demonstration and processes recommended for contaminated sediment cleanup projects. Given the amount of contaminated water generated by the handling and treatment of sediment, the guide also describes technologies demonstrated or under demonstration for effluent or leachate treatment.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Preindustrial marine clays, often dredged in the maritime seaway, represent a concern for the environment management as they are considered potentially toxic with regards of the sediment quality criteria. A research project was initiated in 1999, at the St. Lawrence Centre, to better document the background levels of target chemicals in these "uncontaminated" sediments. The results highlight the association of Cr and Ni to the inert silicate fraction of marine clay sediments, whereas Cd, Pb, Zn as well as Cd and Hg display generally an affinity towards more reactive phases of the sediment. The latter trace metals in these sediments are not an issue for dredged material management as their levels are always close to the no-effect level. Future results will include normalization of trace metal concentrations with organic carbon content, grain size distribution and conservative elements such as Al and Li, for a better application of the criteria to preindustrial marine clays.
