This book was released on 2018-05-18 with total page 775 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millions of Americans use e-cigarettes. Despite their popularity, little is known about their health effects. Some suggest that e-cigarettes likely confer lower risk compared to combustible tobacco cigarettes, because they do not expose users to toxicants produced through combustion. Proponents of e-cigarette use also tout the potential benefits of e-cigarettes as devices that could help combustible tobacco cigarette smokers to quit and thereby reduce tobacco-related health risks. Others are concerned about the exposure to potentially toxic substances contained in e-cigarette emissions, especially in individuals who have never used tobacco products such as youth and young adults. Given their relatively recent introduction, there has been little time for a scientific body of evidence to develop on the health effects of e-cigarettes. Public Health Consequences of E-Cigarettes reviews and critically assesses the state of the emerging evidence about e-cigarettes and health. This report makes recommendations for the improvement of this research and highlights gaps that are a priority for future research.

Download or read book Emulsifiers in Food Technology written by Viggo Norn and published by John Wiley & Sons. This book was released on 2015-01-20 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emulsifiers are essential components of many industrial food recipes. They have the ability to act at the interface between two phases, and so can stabilise the desired mix of oil and water in a mayonnaise, ice cream or salad dressing. They can also stabilise gas/liquid mixtures in foams. More than that, they are increasingly employed in textural and organoleptic modification, in shelf life enhancement, and as complexing or stabilising agents for other components such as starch or protein. Applications include modifying the rheology of chocolate, the strengthening of dough, crumb softening and the retardation of staling in bread. This volume, now in a revised and updated second edition, introduces emulsifiers to those previously unfamiliar with their functions, and provides a state of the art account of their chemistry, manufacture, application and legal status for more experienced food technologists. Each chapter considers one of the main chemical groups of food emulsifiers. Within each group the structures of the emulsifiers are considered, together with their modes of action. This is followed by a discussion of their production / extraction and physical characteristics, together with practical examples of their application. Appendices cross-reference emulsifier types with applications, and give E-numbers, international names, synonyms and references to analytical standards and methods. This is a book for food scientists and technologists, ingredients suppliers and quality assurance personnel.

This book was released on 2019-09-17 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents a cost analysis of Propylene Glycol production from propylene oxide. The process examined is a typical hydration process, in which propylene oxide is hydrolyzed to Propylene Glycol. The hydration reaction output is purified, yielding Propylene Glycol as the main product and dipropylene glycol as by-product. This report was developed based essentially on the following reference(s): (1) "Propanediols," Ullmann's Encyclopedia of Industrial Chemistry, 7th edition (2) "Glycols, Propylene Glycols," Kirk-Othmer Encyclopedia of Chemical Technology, 5th edition Keywords: PO, Epoxypropane, Propane-1,2-diol

This book was released on 1995-05-12 with total page 988 pages. Available in PDF, EPUB and Kindle. Book excerpt: People are increasingly concerned about potential environmental health hazards and often ask their physicians questions such as: "Is the tap water safe to drink?" "Is it safe to live near power lines?" Unfortunately, physicians often lack the information and training related to environmental health risks needed to answer such questions. This book discusses six competency based learning objectives for all medical school students, discusses the relevance of environmental health to specific courses and clerkships, and demonstrates how to integrate environmental health into the curriculum through published case studies, some of which are included in one of the book's three appendices. Also included is a guide on where to obtain additional information for treatment, referral, and follow-up for diseases with possible environmental and/or occupational origins.

Download or read book Emergency and Continuous Exposure Guidance Levels for Selected Submarine Contaminants written by National Research Council and published by National Academies Press. This book was released on 2009-10-21 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: U.S. Navy personnel who work on submarines are in an enclosed and isolated environment for days or weeks at a time when at sea. Unlike a typical work environment, they are potentially exposed to air contaminants 24 hours a day. To protect workers from potential adverse health effects due to those conditions, the U.S. Navy has established exposure guidance levels for a number of contaminants. The Navy asked a subcommittee of the National Research Council (NRC) to review, and develop when necessary, exposure guidance levels for specific contaminants. This volume, the third in a series, recommends 1-hour and 24-hour emergency exposure guidance levels (EEGLs) and 90-day continuous exposure guidance levels (CEGLs) for acetaldehyde, hydrogen chloride, hydrogen fluoride, hydrogen sulfide, and propylene glycol dinitrate.
