Download or read book Damp Indoor Spaces and Health written by Institute of Medicine and published by National Academies Press. This book was released on 2004-10-01 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Almost all homes, apartments, and commercial buildings will experience leaks, flooding, or other forms of excessive indoor dampness at some point. Not only is excessive dampness a health problem by itself, it also contributes to several other potentially problematic types of situations. Molds and other microbial agents favor damp indoor environments, and excess moisture may initiate the release of chemical emissions from damaged building materials and furnishings. This new book from the Institute of Medicine examines the health impact of exposures resulting from damp indoor environments and offers recommendations for public health interventions. Damp Indoor Spaces and Health covers a broad range of topics. The book not only examines the relationship between damp or moldy indoor environments and adverse health outcomes but also discusses how and where buildings get wet, how dampness influences microbial growth and chemical emissions, ways to prevent and remediate dampness, and elements of a public health response to the issues. A comprehensive literature review finds sufficient evidence of an association between damp indoor environments and some upper respiratory tract symptoms, coughing, wheezing, and asthma symptoms in sensitized persons. This important book will be of interest to a wide-ranging audience of science, health, engineering, and building professionals, government officials, and members of the public.

Download or read book Mycotoxins and Animal Foods written by DUPLICATE Smith and published by CRC Press. This book was released on 1991-07-23 with total page 902 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ingestion of feed containing mycotoxins has serious adverse effects on the health of farm animals, contributing to reduced weight gain, lower reproductivity, damage to the immune system, severe illnesses, and even death. Mycotoxins formed in animal feedstuffs depend on the presence of specific strains of filamentous fungi or molds and are strongly influenced by environmental factors such as temperature and humidity. This book considers the biological nature of mycotoxin formation, the chemical and biological methods of analysis, as well as the extensive range of substrates capable of supporting the growth of toxigenic fungi. The book also provides extensive coverage of the mycotoxicoses of farmed animals and the current state of research into the control and detoxification of mycotoxins. All researchers interested in mycotoxins and their effects on animals will find important information in this book.
Download or read book Aflatoxin written by Lukman Abdulra'Uf and published by BoD – Books on Demand. This book was released on 2017-08-30 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aflatoxins are a group of highly toxic and carcinogenic substances, which occur naturally, and can be found in food substances. Aflatoxins are secondary metabolites of certain strains of the fungi Aspergillus flavus and A. parasiticus and the less common A. nomius. Aflatoxins B1, B2, G1, and G2 are the most important members, which can be categorized into two groups according to the chemical structure. As a result of the adverse health effects of mycotoxins, their levels have been strictly regulated especially in food and feed samples. Therefore, their accurate identification and determination remain a Herculean task due to their presence in complex food matrices. The great public concern and the strict legislation incited the development of reliable, specific, selective, and sensitive analytical methods for pesticide monitoring that are discussed in this book.
Download or read book Mycotoxin Protocols written by Mary W. Trucksess and published by Springer Science & Business Media. This book was released on 2008-02-05 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mycotoxins produced by molds are common contaminants of many important crops, including wheat, corn, rice, and peanuts. Some mycotoxins are found in fruits and vegetables. These contaminants have a broad range of toxic effects, including carcinogenicity, neurotoxicity, and reproductive and developmental toxicity. The occurrence of mycotoxins in foods is an unavoidable worldwide problem. About 80 countries have imposed regulatory limits to minimize human and animal exposure to mycotoxins. Regulatory limits, including international standards, have tremendous economic impact and must be developed using science-based risk assessments. The purpose of Mycotoxin Protocols is to provide the scientific and technological basis for analytical methods for use in obtaining the exposure data needed for risk assessments. Mycotoxin Protocols is divided into four sections, which are interc- nected. The first section: Chapters 1–5 describe the general techniques for mycotoxin analysis with emphasis on the importance of method validation based on statistical parameters; sampling procedures for collecting a sample as representative as possible of a bulk lot; the isolation of mycotoxins for use as analytical standards or for toxicological studies; the evaluation of purity and preparation of standards; and the detection and identification of impu- ties in isolated mycotoxins. Sections 2–4: Chapters 6–19 describe the most current chromatographic and immunochemical methods for studies on the major mycotoxins.

Download or read book The Biosynthesis of Mycotoxins written by Pieter Steyn and published by Elsevier. This book was released on 2012-12-02 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Biosynthesis of Mycotoxins: A Study in Secondary Metabolism focuses on the biosynthetic analysis of mycotoxins, which are inherently a heterogeneous group of metabolites that are formed along the terpene route and the route polyketide, as well as from amino acids. This book discusses the unique biological properties and structural complexity of the highly specialized secondary microbial metabolites. Organized into 12 chapters, this book starts with an overview of the characteristics of secondary metabolites, including their problematic function and the combination of their structural diversity with their restricted biological occurrence. This text then explains the sporadic occurrence of the mycotoxins as fungal metabolites. Other chapters explore ergochromes, which are a group of light yellow mycotoxins that are isolated from ergot, mold fungi, and lichens. The final chapter discusses the biosynthesis of several unrelated fungal metabolites for which toxicological data are reported. Biochemists, organic chemists, mycologists, enzymologists, plant pathologists, toxicologists, and graduate students will find this book useful.

Download or read book Carcinogens and Anticarcinogens in the Human Diet written by National Research Council and published by National Academies Press. This book was released on 1996-03-12 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite increasing knowledge of human nutrition, the dietary contribution to cancer remains a troubling question. Carcinogens and Anticarcinogens assembles the best available information on the magnitude of potential cancer riskâ€"and potential anticarcinogenic effectâ€"from naturally occurring chemicals compared with risk from synthetic chemical constituents. The committee draws important conclusions about diet and cancer, including the carcinogenic role of excess calories and fat, the anticarcinogenic benefit of fiber and other substances, and the impact of food additive regulation. The book offers recommendations for epidemiological and diet research. Carcinogens and Anticarcinogens provides a readable overview of issues and addresses critical questions: Does diet contribute to an appreciable proportion of human cancer? Are there significant interactions between carcinogens and anticarcinogens in the diet? The volume discusses the mechanisms of carcinogenic and anticarcinogenic properties and considers whether techniques used to evaluate the carcinogenic potential of synthetics can be used with naturally occurring chemicals. The committee provides criteria for prioritizing the vast number of substances that need to be tested. Carcinogens and Anticarcinogens clarifies the issues and sets the direction for further investigations into diet and cancer. This volume will be of interest to anyone involved in food and health issues: policymakers, regulators, researchers, nutrition professionals, and health advocates.
