Book Synopsis Arsenic in Drinking Water by : National Research Council
Download or read book Arsenic in Drinking Water written by National Research Council and published by National Academies Press. This book was released on 2001-11-26 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Having safe drinking water is important to all Americans. The Environmental Protection Agency's decision in the summer of 2001 to delay implementing a new, more stringent standard for the maximum allowable level for arsenic in drinking water generated a great deal of criticism and controversy. Ultimately at issue were newer data on arsenic beyond those that had been examined in a 1999 National Research Council report. EPA asked the National Research Council for an evaluation of the new data available. The committee's analyses and conclusions are presented in Arsenic in Drinking Water: 2001 Update. New epidemiological studies are critically evaluated, as are new experimental data that provide information on how and at what level arsenic in drinking water can lead to cancer. The report's findings are consistent with those of the 1999 report that found high risks of cancer at the previous federal standard of 50 parts per billion. In fact, the new report concludes that men and women who consume water containing 3 parts per billion of arsenic daily have about a 1 in 1,000 increased risk of developing bladder or lung cancer during their lifetime.

Book Synopsis Total Diet Studies by : Gerald G. Moy
Download or read book Total Diet Studies written by Gerald G. Moy and published by Springer. This book was released on 2016-08-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unless a food is grossly contaminated, consumers are unable to detect through sight or smell the presence of low levels of toxic chemicals in their foods. Furthermore, the toxic effects of exposure to low levels of chemicals are often manifested slowly, sometimes for decades, as in the case of cancer or organ failure. As a result, safeguarding food from such hazards requires the constant monitoring of the food supply using sophisticated laboratory analysis. While the food industry bears the primary responsibility for assuring the safety of its products, the overall protection of people’s diets from chemical hazards must be considered one of the most important public health functions of any government. Unfortunately, many countries do not have sufficient capability and capacity to monitor the exposure of their populations to many potentially toxic chemicals that could be present in food and drinking water. Without such monitoring, public health authorities in many countries are not able to identify and respond to problems posed by toxic chemicals, which may harm their population and undermine consumer confidence in the safety of the food supply. From a trade perspective, those countries that cannot demonstrate that the food they produce is free of potentially hazardous chemicals will be greatly disadvantaged or even subject to sanctions in the international marketplace. The goal of a total diet study (TDS) is to provide basic information on the levels and trends of exposure to chemicals in foods as consumed by the population. In other words, foods are processed and prepared as typical for a country before they are analyzed in order to better represent actual dietary intakes. Total diet studies have been used to assess the safe use of agricultural chemicals (e.g., pesticides, antibiotics), food additives (e.g., preservatives, sweetening agents), environmental contaminants (e.g., lead, mercury, arsenic, cadmium, PCBs, dioxins), processing contaminants (e.g., acrylamide, polycyclic aromatic hydrocarbons, chloropropanols), and natural contaminants (e.g., aflatoxin, patulin, other mycotoxins) by determining whether dietary exposure to these chemicals are within acceptable limits. Total diet studies can also be applied to certain nutrients where the goal is to assure intakes are not only below safe upper limits, but also above levels deemed necessary to maintain good health. International and national organizations, such as the World Health Organization, the European Food Safety Agency and the US Food and Drug Administration recognize the TDS approach as one of the most cost-effective means of protecting consumers from chemicals in food, for providing essential information for managing food safety, including food standards, and for setting priorities for further investment and study. Total Diet Studies introduces the TDS concept to a wider audience and presents the various steps in the planning and implementation of a TDS. It illustrates how TDSs are being used to protect public health from chemicals in the food supply in many developed and developing countries. The book also examines some of the applications of TDSs to specific chemicals, including contaminants and nutrients.

This book was released on 2018-06-22 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bachelor Thesis from the year 2017 in the subject Engineering - Metal Engineering / Metal Processing / Metal Structure, grade: -, , language: English, abstract: In the industry of crude oil refining, can be found wide range of applications of ferrous metals such as in the storage and transportation. The corrosion is a kind of major problem faced in the usage of such ferrous metals. The formation of the oxides, sulfides, hydroxides or the compound related to the carboxylic group on the surface of metal due to the chemical reaction between metals and surrounding are known as the corrosion which is highly depended on the sulfur content, salt content, mercaptans content and the acidity of crude oil as well as the chemical composition of ferrous metals. In the current research it was expected to investigate the effect of Murban and Das blend crude oils on the rate of corrosion of seven different ferrous metals which are used in the crude oil refining industry and also expected to investigate the change in hardness of each metal due to the corrosion. The sulfur content, acidity and salt content of each crude oil were determined. A series of similar pieces of seven different types of ferrous metals were immersed in each crude oil separately for 15, 30 and 45 days. Their rate of corrosion was determined by using their relative weight loss after these time periods. The corroded metal surfaces were observed under the microscope. The hardness of each metal piece was tested before the immersion in crude oil and after the corrosion with the aid of Vicker’s hardness tester. It was found that blend crude oil contains higher sulfur content and acidity than Murban crude oil. Carbon steel metal pieces show the highest corrosion rates whereas the stainless steel metal pieces show the least corrosion rates in both crude oils. The mild steel piece and the Monel piece show relatively intermediate corrosion rates compared to the other types of ferrous metal pieces in both crude oils. It can be observed that there is a slight decrease in hardness of all the ferrous metal pieces due to corrosion. The corrosion rates of ferrous metals are varied with the properties of crude oils such as sulfur content, acidity and the amount of mercaptans present. Finally the relevant metallic concentration of each crude oil sample was tested using atomic absorption spectroscopy (AAS). According to those results significant Fe and Cu concentrations were observed from some of crude oil samples.

Download or read book Atmospheric Corrosion written by Christofer Leygraf and published by John Wiley & Sons. This book was released on 2016-06-07 with total page 509 pages. Available in PDF, EPUB and Kindle. Book excerpt: ATMOSPHERIC CORROSION Presents a comprehensive look at atmospheric corrosion, combining expertise in corrosion science and atmospheric chemistry Atmospheric corrosion has been a subject of engineering study, largely empirical, for nearly a century. Scientists came to the field rather later on and had considerable difficulty bringing their arsenal of tools to bear on the problem. Atmospheric corrosion was traditionally studied by specialists in corrosion having little knowledge of atmospheric chemistry, history, or prospects. Atmospheric Corrosion provides a combined approach bringing together experimental corrosion and atmospheric chemistry. The second edition expands on this approach by including environmental aspects of corrosion, atmospheric corrosion modeling, and international corrosion exposure programs. The combination of specialties provides a more comprehensive coverage of the topic. These scientific insights into the corrosion process and its amelioration are the focus of this book. Key topics include the following: Basic principles of atmospheric corrosion chemistry Corrosion mechanisms in controlled and uncontrolled environments Degradation of materials in architectural, transport, and structural applications; electronic devices; and cultural artifacts Protection of existing materials and choosing new ones that resist corrosion Prediction of how and where atmospheric corrosion may evolve in the future Complete with appendices discussing experimental techniques, computer models, and the degradation of specific metals, Atmospheric Corrosion, Second Edition continues to be an invaluable resource for corrosion scientists, corrosion engineers, conservators, environmental scientists, and anyone interested in the theory and application of this evolving field. The book concerns primarily the atmospheric corrosion of metals and is written at a level suitable for advanced undergraduates or beginning graduate students in any of the physical or engineering sciences.

Book excerpt: Presentation slides from the year 2017 in the subject Chemistry - Materials Chemistry, grade: 0.9, Srinivas School of Engineering, language: English, abstract: This presentation deals with organic inhibitors on the corrosion of steel and zinc.In the19th century, as the result of technological innovations, revolution in the industry, advancement in the science field, there was a growth in agricultural, industrial production, economic expansion and tremendous changes. People have changed the way of manufacturing processes during this time. All the hand works shifted to the machines. As a result of this revolution, the products were quite cheaper. Mild steel and zinc are very active in the presence of aggressive environment. In the presence of moisture and air, they give respective oxide. It results in the deterioration of metals take place that results in the failures in the industrial equipment in oil industries, gas industries, and water circulating cooling systems. These are main disadvantages of mild steel and zinc. The cause of corrosion of mild steel and zinc and the corrosion control is having critical fundamental, industrial and academic concern .In the existed literature various type of various research groups developed inhibitors. The developed inhibitors, few of them satisfied all the requirements of the industries and society. Even though they are toxic in nature, they aren’t showing inhibition at high temperature. In addition, no one has discussed complete mechanism of corrosion inhibition. In the present study, more attention is given to developing eco-friendly inhibitors. The complete mechanism of inhibition action of these inhibitors were evaluated by using practical and theoretical studies like weight loss, polarization, impedance, activation parameters, thermodynamic parameters. Scanning electron microscope is used to do morphological studies of the inhibitor. The quantum chemical studies are carried out to correlate the theoretical studies with experimental work of corrosion inhibitors. All the results were agreeing with each other. All the developed inhibitors find applications in industries.
