Download or read book 1987 WET DEPOSITION TEMPORAL AND SPATIAL PATTERNS IN NORTH AMERICA written by A. R. Olsen and published by . This book was released on 1990 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research project is to determine the spatial pattern of wet deposition in North America during 1987 and to investigate trends in wet deposition in North America from 1979 through 1987. The project considers precipitation-weighted average concentration and deposition for nine ion species: hydrogen ion, sulfate, nitrate, ammonium, calcium, chloride, sodium, potassium, and magnesium. To accomplish the research an Acid Deposition System (ADS) data base has been established that integrates wet deposition monitoring data from several regional and national monitoring networks. Networks included are the National Atmospheric Deposition Program/National Trends Network (NADP/NTN), the MAP3S precipitation chemistry network, the Utility Acid Precipitation Study Program (UAPSP) network, the Canadian Precipitation Monitoring Network (CAPMoN), and the daily and 4-weekly Acidic Precipitation Monitoring in Ontario Study networks (APIOS-D and APIOS-C). The ADS data base and statistical summaries are available to others to conduct additional research studies.

Download or read book 1986 Wet Deposition Temporal and Spatial Patterns in North America written by and published by . This book was released on 1989 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of this report is on North American wet deposition temporal patterns from 1979 to 1986 and spatial patterns for 1986. The report provides statistical distribution summaries of annual precipitation-weighted average concentration and annual deposition for nine ion species: hydrogen, sulfate, nitrate, ammonium, calcium, chloride, sodium, potassium, and magnesium. The data in the report are from the Acid Depositing System (ADS) for the statistical reporting of North American deposition data. Isopleth maps, based on surface estimation using kriging, display concentration and deposition spatial patterns of pH, hydrogen, sulfate, nitrate, ammonium, and calcium ion species for 1986 annual, winter, and summer periods. The temporal pattern analyses use a subset of 30 sites over an 8-year (1979-1986) period and an expanded subset of 137 sites with greater spatial coverage over a 5-year (1982-1986) period. The 8-year period represents the longest period with wet deposition monitoring data unavailable that has a sufficient number of sites with data of known quality to allow a descriptive summary of annual temporal patterns. 19 refs., 105 figs., 29 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: The focus of this report is on North American wet deposition temporal patterns from 1979 to 1988 and spatial patterns for 1988. It is the third in a series of reports that investigate the patterns of annual precipitation-weighted average concentration and annual deposition for nine ion species: hydrogen, sulfate, nitrate, ammonium, calcium, chloride, sodium, potassium, and magnesium. Mosaic maps, based on surface estimation using kriging, display concentration and deposition spatial patterns of pH, hydrogen, sulfate, nitrate, ammonium, and calcium ion species for 1988 annual, winter, and summer periods. Temporal pattern analyses use a subset of 35 sites over a 10-year (1979--1988) period and an expanded subset of 137 sites, with greater spatial coverage, over a 7-year (1982--1988) period. The 10-year period represents the longest period with wet deposition monitoring data available that has a sufficient number of sites with data of known quality to allow a descriptive summary of annual temporal patterns. Sen's median trend estimate and Kendall's seasonal tau (KST) test are calculated for each ion species concentration and deposition at each site in both subsets.

Download or read book Resources and References written by Donna S. Kocurek and published by Elsevier. This book was released on 1995-12-31 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guide book provides references and resources for the complex field of hazardous waste and hazardous materials management. The book is divided into general topics such as air quality, industrial wastewater, pollution prevention, and risk assessment under hazardous waste management and chemical hazards, emergency planning, and hazard communication under hazardous materials management. Each individual section includes a list of annotated bibliographies of the most recent books by major publishers as well as established, standard references. Following the annotated titles, are additional references of books and documents by publishers, technical associations, and governmental agencies (primarily the U.S. Environmental Protection Agency). In general, only references from 1986 onward are included since the technology and regulations affecting hazardous waste and materials are constantly evolving. Additional resources included in the book are video tapes for training and instruction, information services and databases, libraries, agency contacts, technical journals, and a list of publishers and ordering information. This book will be a useful reference to professionals in the environmental field who need an extensive, but concise source of technical information and contacts. The book will be a valuable addition to individual libraries and will fill a current reference void in university libraries, and technical libraries in industry and government. At present there are very few technical bibliographies in the field, and none has covered topics related to hazardous materials and hazardous waste as extensively as this book.

Available in PDF, EPUB and Kindle. Book excerpt: The new revised edition of a classic Earth science text This newly revised edition of Global Environment discusses the major elements of the geochemical cycles and global fluxes found in the atmosphere, land, lakes, rivers, biota, and oceans, as well as the human effects on these fluxes. Retaining the strengths of the original edition while incorporating the latest discoveries, this textbook takes an integrated, multidisciplinary, and global approach to geochemistry and environmental problems and introduces fundamental concepts of meteorology, surficial geology (weathering, erosion, and sedimentation), biogeochemistry, limnology, and oceanography. New concepts and information in this updated edition include changes of atmospheric carbon dioxide over geologic time, major advances in the study of chemical weathering of rocks, ocean acidification, and important environmental problems, such as the amelioration of the acid rain problem due to reduction in sulfur deposition, problems with nitrification of soils and lakes, and eutrophication of rivers and estuaries. An expanded chapter explores atmospheric chemistry and changing climate, with the most up-to-date statistics on CO2, the carbon cycle, other greenhouse gases, and the ozone hole. Only requiring a fundamental understanding in elementary chemistry, yet taking into account extensive and current data, this text is ideal for students in environmental geochemistry, environmental geology, global change, biogeochemistry, water pollution, geochemical cycles, chemical oceanography, and geohydrology, and serves as a valuable reference for researchers working on global geochemical and environmental issues. Revised edition takes a close look at global fluxes involving the atmosphere, land, lakes, rivers, biota, and oceans, and the human effects on these fluxes Detailed discussion of basic concepts including meteorology, surficial geology (weathering, erosion, and sedimentation), biogeochemistry, limnology, and oceanography An expanded up-to-date chapter on atmospheric chemistry and changing climate, including CO2, other greenhouse gases, and ozone Presentation of major advances in the study of chemical weathering Discussion of current environmental topics Global coverage of environmental problems involving water
