Download or read book Nitrate Handbook written by Christos Tsadilas and published by CRC Press. This book was released on 2022-01-03 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrate Handbook: Environmental, Agricultural, and Health Effects provides an overview of the entire nitrate cycle and the processes influencing nitrate transformation. It clearly identifies the role of nitrate as an essential nutrient in plant growth, food preservation, and human health. Using the most up-to-date knowledge and research, this handbook illustrates how the steadily increasing human population and demand for food, which results in higher amounts of nitrate needed by soils, makes new regulations on the management and usage of nitrates a high priority. A detailed explanation concerning the discrepancies between the public’s perception of nitrate’s harm versus the reality of its human health benefits is given via a balanced and evidence-based approach. All questions pertaining to the influences of nitrate and its derivatives on plant physiology and human health are explored in depth. This comprehensive resource with contributions from distinguished researches in the field is a must-have for professionals and students who study and work with nitrates. Features: Includes in depth discussion on the wide spectrum of nitrate present in the environment. Focuses on the progress made on nitrate research and its importance. Answers all questions about nitrate and its derivatives’ influences on plant physiology and human health. Enables decision makers and public authorities to manage social concerns Compiles in one resource the findings of many distinguished researchers in the field.
Download or read book The North American Mosaic written by Commission for Environmental Cooperation (Montréal, Québec). Secretariat and published by . This book was released on 2001 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

This book was released on 2000 with total page 740 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardbound. Our modern economies consume annually about 4.6 billion metric tons of crude oil, a third of which is shipped across the oceans. Along the way, about 3 million metric tons are lost into the environment, primarily through handling in ports, but also leakage at sea. So, the threat of a major ecological disaster is always present, for example the Exxon Valdez, Braer and Sea Empress accidents. In addition to oil leakage from tankers, considerable quantities of oil enter the sea from operational discharges or bunker spills. Fortunately, current international agreements, though not always strictly enforced, have greatly reduced the threat of oil pollution.The oceans are faced with an onslaught from many other sources. The potential for radioactive pollution of the seas, through dumping of nuclear wastes or an accident to a ship carrying radioactive nuclear wastes, has never been absent from the public mind. Recently, people have become more awar
Download or read book Biological Monitoring written by Shane Que Hee and published by John Wiley & Sons. This book was released on 1993-06-01 with total page 676 pages. Available in PDF, EPUB and Kindle. Book excerpt: This definitive source provides practicing professionals and students in the occupational, environmental, and public health and safety fields with the functional basics of biological monitoring. The author examines how environmental exposures to particular chemicals are related to concentrations of markers in body tissues and fluids. Biological Monitoring integrates the applied sciences of industrial/environmental hygiene, epidemiology, public health, occupational medicine, toxicology, biochemistry, and analytical chemistry with the basic sciences to interpret the connections between exposures and lifestyle/environmental influences, and their effects on humans. This comprehensive introduction provides dependable, detailed coverage of: * monitoring for harmful substances in the workplace * the benefits and limitations of testing for critical levels of toxic materials in bodily tissues and fluids * state-of-the-art developments in biological monitoring * a wide variety of toxic chemicals and selected physical agents * immunoassays * monitoring for HIV and AIDS * importance of exposure routes * the most up-to-date methods of health and medical surveillance * the interpretation of adduct concentrations * biological exposure indices * biological monitoring of pesticides * biological monitoring in the home and around hazardous waste sites * and much more This essential, compelling guide is the only inclusive and thorough introduction available. Biological Monitoring's rigorous, accessible, interdisciplinary approach makes this an invaluable reference and text for industrial and environmental hygienists, physicians, pharmacists, nurses, epidemiologists, toxicologists, laboratory technicians, chemical engineers, science graduate students, and the environmentally concerned.

This book was released on 2012-12-06 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: The determination of the hazards resulting from the accidental or deli berate contamination of terrestrial and aquatic environments is in most countries still lirnited to the detection and quantification of the suspected pollutants by chemical analyses. Such an approach is unfortunately hampered by the following constraints : the costs as weil as the technical difficulties of analyzing every individual chemical which may be present in the sampies, and the difficulty of assessing the hazards and risks of environmental contaminations from a set of chemical data. During the last decades the scientific and regulatory community has gradually realized that biological methodologies have to be taken into consideration for an ecologically meaningful assessment of the toxicological hazards of contaminants. Effect evaluations obtained with biological techniques indeed integrate the impact of all the contaminants to which living biota are exposed. Bioassays with selected test species representative for the biological commumtles of the environments under consideration, are now applied more or less regularly to determine toxic and genotoxic effects. Taking into account the species specific and chemical specific character of toxicity to biota, the necessity of a «battery of tests» approach with species of different trophic levels is currently also generally accepted and implemented. It is dear that a balanced partnership between chemical, biological, toxicological and microbiological analyses is always the best strategy for generating the broadest information base on environmental hazards.

Download or read book The Failure of Modern Civilization and the Struggle for a deep Alternative written by Claudia von Werlhof and published by Beiträge zur Dissidenz. This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Western civilization is the Utopia of a better and higher life on Earth. The globalization of neo-liberalism proves that this project has failed. The paradigm of «Critical Theory of Patriarchy» explains this failure and discusses alternatives. By confronting the central civilizations in history, the egalitarian, life-oriented matriarchal one, and the hierarchical, nature and life dominating, hostile patriarchal one, we see that 5000 years of patriarchy have «replaced» matriarchies and nature itself by a «progressive» counter-world of «capital». This transformation characterizes «capitalist patriarchy» including «socialism». Its demise is due to the «alchemical» destruction of the world's resources, thought of, theologically legitimized and fetishized as «creation». This violence is not recognized. Elites have, instead, begun with a new «military alchemy», treating the whole Planet as weapon of mass destruction. Hence, the «Planetary Movement for Mother Earth».
