Available in PDF, EPUB and Kindle. Book excerpt: "World War II was the largest and most destructive conflict in human history. It was an existential struggle that pitted irreconcilable political systems and ideologies against one another across the globe in a decade of violence unlike any other. There is little doubt today that the United States had to engage in the fighting, especially after the Japanese attack on Pearl Harbor on December 7, 1941. The conflict was, in the words of historians Allan Millett and Williamson Murray, "a war to be won." As the world's largest industrial power, the United States put forth a supreme effort to produce the weapons, munitions, and military formations essential to achieving victory. When the war finally ended, the finale signaled by atomic mushroom clouds over Hiroshima and Nagasaki, upwards of 60 million people had perished in the inferno. Of course, the human toll represented only part of the devastation; global environments also suffered greatly. The growth and devastation of the Second World War significantly changed American landscapes as well. The war created or significantly expanded a number of industries, put land to new uses, spurred urbanization, and left a legacy of pollution that would in time create a new term: Superfund site"--

Download or read book Nitrate Contamination written by Istvan Bogardi and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nitrate content of drinking water is rising at an alarming rate in several regions of NATO countries and elsewhere in the world. The increase is due to lack of proper sewage treatment, and primarily to excess fertilizer application. Also, eutrophication in several coastal areas is triggered by high nitrate concentrations. The main purpose of this book is to integrate scientific knowledge related to exposure assessment, health consequences and control of nitrate contamination in water. The motivation is related to the magnitude, the possible adverse health effects, and the high cost of control ling nitrate contamination. Future research tasks are defined by an interaction among hydro logists, toxicologists and environmental engineers in an integrated framework for nitrate risk management. The target readership of this book is a mix of university colleagues, practitioners from both the private and public sectors and advanced graduate students working with the hydrological, health science or environmental engineering aspects of nitrate contamination. The main conclusions include: 1. For risk assessment purposes, knowledge and sufficiently accurate models are available to predict nitrate load and its fate in water under changes in land use. 2. Once agricultural exposure controls are implemented, the response times in ground water may be so long as to make controls unrealistic. 3. It is still unknown whether agricultural best management practice is a compromise between nitrate risk reduction and agricultural revenue. 4. The current drinking water guidelines of 10 mg/L NOrN need not be changed.
