Available in PDF, EPUB and Kindle. Book excerpt: Effective management of urban water should be based on a scientific understanding of the impact of human activity on both the urban hydrological cycle - including its processes and interactions - and the environment itself. Such anthropogenic impacts, which vary broadly in time and space, need to be quantified with respect to local climate, urban d

Download or read book Chemical Contaminants in Canadian Aquatic Ecosystems written by D. M. Whittle and published by Canadian Government Publishing. 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.

Available in PDF, EPUB and Kindle. Book excerpt: Aquatic habitats supply a wide range of vital ecosystem benefits to cities and their inhabitants. The unsustainable use of aquatic habitats, including inadequate urban water management itself, however, tends to alter and reduce their biodiversity and therewith diminish their ability to provide clean water, protect us from waterborne diseases and po

Available in PDF, EPUB and Kindle. Book excerpt: The Toxic Substances Management Policy calls for the virtual elimination of all toxic, persistent bioaccumulative substances. This action plan falls under this policy. This document lays out the action plan with targeted actions for substances (carbon tetrachloride, methyl chloroform, chloromethyl methyl ether & bis ether - CMME, BCME, tetra- and trichloroethylene, 3,3 dichlorobenzidine, chlorofluorocarbons - CFC, short chain chlorinated paraffins - SCCP, chlorinated dioxins & furans, and others), and for industries. The report also discusses improving scientific understanding, public health & socio-economic studies, information, and international actions. Emission reductions, guidelines & agreements are discussed in annexes.

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.

This book was released on 2005 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximately 3 million gallons of oil or refined petroleum products are spilled into U.S. waters every year. Oil dispersants (chemical agents such as surfactants, solvents, and other compounds) are used to reduce the effect of oil spills by changing the chemical and physical properties of the oil. By enhancing the amount of oil that physically mixes into the water, dispersants can reduce the potential that a surface slick will contaminate shoreline habitats. Although called for in the Oil Pollution Act of 1990 as a tool for minimizing the impact of oil spills, the use of chemical dispersants has long been controversial. This book reviews the adequacy of existing information and ongoing research regarding the effectiveness of dispersants as an oil spill response technique, as well as the effect of dispersed oil on marine and coastal ecosystems. Oil Spill Dispersants also includes recommended steps for policy makers faced with making hard choices regarding the use of dispersants as part of spill contingency planning efforts or during actual spills.
