Download or read book Concentrations of Metallothionein in Fish Peace Athabasca and Slave River Basins September to December 1994 written by J. F. Klaverkamp and published by . This book was released on 1996 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metallothioneins are a family of proteins whose synthesis in animal organs and tissues can be induced by exposure to heavy metals. This report describes metallothionein concentrations in fish collected from northern Alberta rivers and tributaries. The analyses incorporate results from examination of kidney, liver, intestine, and gill tissues of burbot, longnose sucker, northern pike, and flathead chub. Results are organised into reference (upstream locations and tributaries receiving no inputs from pulp mills), near-field (within 100 kilometres downstream from a pulp mill), and far-field (over 100 kilometres downstream).
Download or read book Fish Collections Peace Athabasca and Slave River Basins September to December 1994 written by Toni-Lynne Jacobson and published by . This book was released on 1995 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents a study that collected and prepared fish from 23 sites along the Peace, Athabasca, and Slave river drainages in order to conduct physical, physiological, contaminant, and biophysical analyses. The primary fish species targeted for collection and analysis was burbot, used as a sentinel species for monitoring contaminants in northern waters because of its wide distribution, ease of catching, place at the top of the aquatic food chain, and large liver which can bioaccumulate organic compounds. Other species collected were northern pike, longnose sucker, and flathead chub. Specific analyses included gross pathology, metals, liver mixed function oxygenase induction, sex steroids and gonad morphology, retinols, metallothioneins, and basic life history information. Fish were also examined externally and internally for gross pathological abnormalities and deformities. Appendices contain descriptions of fish collection and handling protocols, as well as detailed data.

Download or read book A Database of Environmental Samples Collected and Analysed for the Northern River Basins Study written by Robert B. More and published by . This book was released on 1996 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: An important component of the Northern River Basins Study was the original data resulting from the collection and analysis of environmental samples. Samples were collected, stored, and analysed by a number of different agencies, and an inventory of samples obtained by the Study and results data were compiled into a single electronic database to ensure future ease of access to the original data. This report describes the data contained in the database, the methods used to compile the database, the media and the nature of the samples, the collection site, and the data collected. Information is provided on which analyses were conducted on samples as well as the values of various parameters measured for the samples. All the files and the data fields that comprise the database are described in the users' guide in the report appendix.

Available in PDF, EPUB and Kindle. Book excerpt: North American and European governments have adopted national programs for environmental monitoring and assessment that include the use of aquatic biota. These programs will use a variety of indicators of environmental health; benthic macroinvertebrates are one of the most promising of them. The chapters in this book deal with the many different approaches available for using benthic macroinvertebrates in biological monitoring programs.
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 Wildlife Ecotoxicology written by John E. Elliott and published by Springer Science & Business Media. This book was released on 2011-08-27 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many books have now been published in the broad field of environmental toxicology. However, to date, none of have presented the often fascinating stories of the wildlife science, and the steps along the way from discovery of problems caused by environmental pollutants to the regulatory and non-regulatory efforts to address the problems. This book provides case by case examinations of how toxic chemical effects on wildlife have brought about policy and regulatory decisions, and positive changes in environmental conditions. Wild animal stories, whether they are about the disappearance of charismatic top predators, or of grossly deformed embryos or frogs, provide powerful symbols that can and have captured the public's imagination and have resulted in increased awareness by decision makers. It is the intent of this book to present factual and balanced overviews and summaries of the science and the subsequent regulatory processes that followed to effect change (or not). We cover a variety of chemicals and topics beginning with an update of the classic California coastal DDT story of eggshell thinning and avian reproduction to more recent cases, such as the veterinarian pharmaceutical that has brought three species of Asian vultures to the brink of extinction. Researchers, regulators, educators, NGOs and the general public will find valuable insights into the processes and mechanisms involved both in environmental scientific investigation and in efforts to effect positive change.
Download or read book Ecological Risk Assessment written by Glenn W. Suter II and published by CRC Press. This book was released on 1992-10-23 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, environmental scientists have been required to perform a new type of assessment-ecological risk assessment. This is the first book that explains how to perform ecological risk assessments and gives assessors access to the full range of useful data, models, and conceptual approaches they need to perform an accurate assessment. It explains how ecological risk assessment relates to more familiar types of assessments. It also shows how to organize and conduct an ecological risk assessment, including defining the source, selecting endpoints, describing the relevant features of the receiving environment, estimating exposure, estimating effects, characterizing the risks, and interacting with the risk manager. Specific technical topics include finding and selecting toxicity data; statistical and mathematical models of effects on organisms, populations, and ecosystems; estimation of chemical fate parameters; modeling of chemical transport and fate; estimation of chemical uptake by organisms; and estimation, propagation, and presentation of uncertainty. Ecological Risk Assessment also covers conventional risk assessments, risk assessments for existing contamination, large scale problems, exotic organisms, and risk assessments based on environmental monitoring. Environmental assessors at regulatory agencies, consulting firms, industry, and government labs need this book for its approaches and methods for ecological risk assessment. Professors in ecology and other environmental sciences will find the book's practical preparation useful for classroom instruction. Environmental toxicologists and chemists will appreciate the discussion of the utility for risk assessment of particular toxicity tests and chemical determinations.
