Book Synopsis Mad Cows and Mother's Milk, Second Edition by : William Leiss
Download or read book Mad Cows and Mother's Milk, Second Edition written by William Leiss and published by McGill-Queen's Press - MQUP. This book was released on 2004-11-25 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Communicating the nature and consequences of environmental and health risks is still one of the most problematic areas of public policy in Western democracies. "Mad Cows and Mother's Milk" outlines the crucial role of risk management in dealing with public controversies and analyses risk communication practice and malpractice to provide a set of lessons for risk managers and communicators. This second edition adds new case studies on mad cow disease in North America, climate change, and genetics technologies. The first of the new case studies brings the story of the Bovine Spongiform Encephalopathy (BSE) outbreak in the United Kingdom in the 1980s up-to-date. Mad cow disease is still being discovered in UK herds and cases of mad cow disease have been found in twenty countries across the European continent and as far away as Japan with devastating consequences for the food industry. BSE has now been discovered on the North American continent in two cows born in Canada. The original cause of these two new cases is almost certainly importation of infected cattle, cattle feed, or both from Britain. Canadian government regulators and those in the cattle industry have failed to correctly assess the risks of the disease in the Canadian herd, take the precautionary measures needed to prevent the spread of disease, and communicate risks and precautionary measures to the public. The second new study deals with global warming. Not only is every aspect of this risk debate both contentious and difficult for the public to understand but the potential consequences of the risks extend all the way to global catastrophe for human civilization. A new chapter outlines the many dimensions of risk debate in the context of the need for effective and sustained dialogue by an informed public. The last new case study provides an introduction to genomic science, which is placed in the context of both the health benefits expected from genetic manipulation and some of the risk factors associated with it. One example is gene therapy, which can be used to eliminate inherited genetic diseases (i.e. cystic fibrosis), enhance human traits (i.e. athletic performance), and perhaps double life-spans. Gene technologies are relevant to some of the most fundamental human values. This new chapter suggests that we must think about the range of new risks introduced by these technologies as well as the potential benefits - and that we should do this collective thinking soon, since, given the furious pace of genomics discoveries, the possibilities will be with us sooner than we imagine. All of the case studies emphasize the need for effective communication about risks to allow effective dialogue by informed publics on health and environmental risks.

Available in PDF, EPUB and Kindle. Book excerpt: The human footprint on the global environment now touches every corner of the world. This book explores the myriad ways that environmental archives can be used to study the distribution and long-term trajectories of chemical contaminants. The volume first focuses on reviews that examine the integrity of the historic record, including factors related to hydrology, post-depositional diffusion, and mixing processes. This is followed by a series of chapters dealing with the diverse archives and methodologies available for long-term studies of environmental pollution, such as the use of sediments, ice cores, sclerochronology, and museum specimens.

Available in PDF, EPUB and Kindle. Book excerpt: When toxins are suspected to be the cause of illness or death, governments, scientists and professional health associations are faced with a dilemma: at what point does sufficient evidence justify changes in policy or the issuance of public warnings which might result in undue public fear? Powell (food science, U. of Guelph) and Leiss (environmental policy, Queen's U., Canada) discuss mad cow's disease, silicone in breast implants, E.coli in hamburger, and dioxins in the environment, in terms of available scientific research and the question of assessing actual risk.

This book was released on 1998 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report focuses on those chemicals that persist in the Canadian environment and that are accumulated by aquatic organisms. It summarizes scientific information collected previously, with emphasis on Canadian research findings published in the last decade. The first part of the report introduces the general features of aquatic ecosystems and provides basic information on the fate and effects of chemical contaminants. The second part reviews contaminant related issues for the following geographic areas: Atlantic marine ecosystems including the St. Lawrence, Bay of Fundy, and general north-west Atlantic; freshwater ecosystems including the Great Lakes and inland waters; the Arctic marine ecosystem; and Pacific aquatic ecosystems including the British Columbia coastal ecosystem, the open coast, and some of the major rivers. All chapters discuss the major contaminant issues, important oceanographic or limnological features, biological resources, and sources of contaminants as well as contaminant trends, distribution, and effects. Current and emerging chemical contaminant issues and associated research topics are summarized at the end of each chapter. The third part is an overall assessment of current knowledge of chemical contaminants and their effects on fish and fish habitat, and identifies major current and emerging contaminant issues confronting Canada's fish and fish habitat.

Book Synopsis Estimating Gulf of Maine Zooplankton Distributions Using Multiple Frequency Acoustic, Video and Environmental Data by : Joseph David Warren
Download or read book Estimating Gulf of Maine Zooplankton Distributions Using Multiple Frequency Acoustic, Video and Environmental Data written by Joseph David Warren and published by . This book was released on 2001 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis develops methods useful for estimating zooplankton distributions in the field by combining acoustic scattering models and an integrated set of field data. The accuracy of existing scattering models for fluid-like and elastic-shelled animals is determined by analysis of scattering data from individual animals in a laboratory tank. Results indicate that simple two-ray scattering models are accurate and allow predictions of size or orientation of an animal to be made for certain animal orientations. A scattering model for gas-bearing zooplankton is compared with in situ multiple frequency acoustic measurements from siphonophores. Estimates of the numerical density of these animals are made using echo integration data from a scientific echo-sounder. Multiple frequency acoustic scattering data from a survey of an internal wave are analyzed to determine the contributions from biological and physical sources. Net tow data provide information about biological scatterers while temperature and salinity profiles are used with a theoretical scattering model to predict contributions from physical sources. Results indicate that scattering from physical sources is comparable to that from biological sources in certain regions and that scattering spectra may be used to distinguish these sources. Improved estimates of biomass from acoustic scattering data were made by accounting for the scattering contributions from physical sources. This is the first work to quantify the scattering contributions from biological and physical sources of scattering in a field study.
