Available in PDF, EPUB and Kindle. Book excerpt: Past generations of industrial development and chemical production are still very much with us-through contaminants they've left in all phases of the ecosystem. Especially vulnerable to this damage: water. Professionals from various disciplines in environmental sciences are becoming increasingly involved in water quality issues. The Manual of Bioassessment of Aquatic Sediment Quality now provides the most current techniques and methods, in the laboratory and the field, to detect and evaluate aquatic contaminants. Designed to complement the analytical methods presented in the companion volume, Manual of Physico-Chemical Analysis of Aquatic Sediments, the Bioassessment edition offers a comprehensive review of chemical forms, encompassing different elements and compounds in sediments, along with evaluation of their availability to aquatic biota. A discussion about the use of reference materials in sediment analysis also accompanies a review of laboratory safety measures. While greater environmental conscientiousness has led to sustainable industrial development and the recycling of materials, there remains the "hidden need" to remediate contaminated water sources throughout the world-essential to the continued survival of all life. The Manual of Bioassessment of Aquatic Sediment Quality will help environmental professionals ensure the protection of life-supporting streams, lakes and oceans throughout the world.

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.
Download or read book Sediment Toxicity Assessment written by G.Allen Burton and published by CRC Press. This book was released on 2018-05-04 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sediment Toxicity Assessment provides the latest information regarding how to evaluate sediment contamination and its effects on aquatic ecosystems. It presents an integrated ecosystem approach by detailing effective assessment methods, considerations, and effects to each major component of marine and freshwater systems, including the benthos, plankton, and fish communities. The approaches emphasize defining habitat conditions (physical and chemical), toxicant bioavailability, factors influencing toxicity (lab and field), biomarkers, acute and chronic toxicity, study design, collection methods, and EPA management strategies. The book also explains how to integrate the assessments. Sediment Toxicity Assessment will be useful to to all environmental managers, environmental scientists, ecotoxicologists, environmental regulators, aquatic ecologists, environmental contractors and consultants, instructors, students, conservation commissions, and environmental activist organizations.

Book excerpt: This document is a compendium of scientifically valid and accepted methods that can be used to assess sediment quality and predict ecological impacts...the intent here is to provide the most useful overall measures or predictors of ecological impacts currently in use rather than procedures that may have limited application outside of a particular regulatory framework... parag The information provided in the compendium on the relative strengths and weaknesses of the different assessment methods can provide assistance in selecting the appropriate methods.

Book excerpt: "Updated every five years by the Working Group on the State of the St. Lawrence Monitoring, the Overview of the State of the St. Lawrence provides a diagnosis of the state of the St. Lawrence River. To do so, partners analyze at regular intervals, some 20 environmental indicators related to water, sediment, biological resources, shorelines and uses of the St. Lawrence River. The results make it possible to assess the state of the ecosystem and to provide guidance for decision-making towards ensuring conservation and sustainability of the St. Lawrence. The Overview also addresses emerging environmental issues in the River: nutrient overload in Lake Saint-Pierre, acidification of the waters of the Gulf of St. Lawrence, and the impacts of climate change on the River's tributaries"--Provided by publisher.
