Book Synopsis Chemical Mixtures and Combined Chemical and Nonchemical Stressors by : Cynthia V. Rider
Download or read book Chemical Mixtures and Combined Chemical and Nonchemical Stressors written by Cynthia V. Rider and published by Springer. This book was released on 2018-02-16 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, both basic and advanced concepts are discussed for considering mixtures from initial exposure characterization through evaluation of risk associated with combined exposures. This book will provide an introduction to key issues and multiple options for evaluating both the toxicity of mixtures as well as the risk associated with exposure to mixtures. Additionally, promising tools adapted from other disciplines will be discussed in the context of mixtures toxicology and risk assessment. Finally, the discussion will move beyond chemical mixtures to address incorporating non-chemical stressors into toxicity studies and cumulative risk assessments. Although exposure to multiple chemical and non-chemical stressors is the rule, not the exception, consideration of mixtures in toxicology and risk assessment continues to be a significant challenge. This book will be an essential resource for researchers and professionals in the fields of toxicology, epidemiology, exposure science, risk assessment, and statistics.

Book Synopsis Carcinogens and Anticarcinogens in the Human Diet by : National Research Council
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.

Download or read book Genetic Toxicology of Complex Mixtures written by Michael D. Waters and published by Springer Science & Business Media. This book was released on 2013-03-13 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contained in this volume are the proceedings of the international conference on the "Genetic Toxicology of Complex Mixtures," held from July 4-7, 1989, in Washington, DC. This meeting was a satellite of the "Fifth International Conference on Environmental Mutagens" and the seventh in a biennial series of conferences on "Short-term Bioassays in the Analysis of Complex Environmental Mixtures. " Our central objective in calling together key researchers from around the world was to extend our knowledge of the application of the methods of genetic toxicology and analytical chemistry in the evaluation of chemical mixtures as they exist in the environment. This conference emphasized the study of genotoxicants in air and water, and the assessment of human exposure and cancer risk. The latest strategies and methodologies for biomonitoring of genotoxicants (including transformation products) were described in the context of the ambient environment. Source character ization and source apportionment were discussed as an aid to understand ing the origin and relative contribution of various kinds of complex mix tures to the ambient environment. Similarly, investigations of genotoxi cants found in the indoor environment (sidestream cigarette smoke) and in drinking water (chlorohydroxyfuranones) were given special attention in terms of their potential health impacts. New molecular techniques were described to enable more precise quantitation of internal dose and dose to-target tissues. The emphasis of presentations on exposures/effects assessment was on integrated quantitative evaluation of human exposure and potential health effects.

Download or read book Some Chemicals Present in Industrial and Consumer Products, Food and Drinking-water written by IARC Working Group on the Evaluation of Carcinogenic Risks to Humans and published by IARC Monographs on the Evaluat. This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of the IARC Monographs provides an assessment of the carcinogenicity of 18 chemicals present in industrial and consumer products or food (natural constituents, contaminants, or flavorings) or occurring as water-chlorination by-products. The compounds evaluated include the widely used plasticizer di(2-ethylhexyl) phthalate and the food contaminant 4-methylimidazole. In view of the limited agent-specific information available from epidemiological studies, the IARC Monographs Working Group relied mainly on carcinogenicity bioassays, and mechanistic and other relevant data to evaluate the carcinogenic hazards to humans exposed to these agents.
Book Synopsis Complex Mixtures by : National Research Council
Download or read book Complex Mixtures written by National Research Council and published by National Academies Press. This book was released on 1988-02-01 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the laboratory, testing the toxic effects for a single compound is a straightforward process. However, many common harmful substances occur naturally as mixtures and can interact to exhibit greater toxic effects as a mixture than the individual components exhibit separately. Complex Mixtures addresses the problem of identifying and classifying complex mixtures, investigating the effect of exposure, and the research problems inherent in testing their toxicity to human beings. A complete series of case studies is presented, including one that examines the cofactors of alcohol consumption and cigarette smoke.

Download or read book How Tobacco Smoke Causes Disease written by United States. Public Health Service. Office of the Surgeon General and published by . This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.
Book Synopsis Modeling Spatially Varying Effects of Chemical Mixtures by : Jenna Czarnota
Download or read book Modeling Spatially Varying Effects of Chemical Mixtures written by Jenna Czarnota and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Cancer incidence is associated with exposures to multiple environmental chemicals, and geographic variation in cancer rates suggests the importance of accommodating spatially varying effects in the analysis of environmental chemical mixtures and disease risk. Traditional regression methods are challenged by the complex correlation patterns inherent among co-occurring chemicals, and the applicability of geographically weighted regression models is limited in the setting of environmental chemical risk analysis. In comparison to traditional methods, weighted quantile sum (WQS) regression performs well in the identification of important environmental exposures, but is limited by the assumption that effects are fixed over space. We present an extension of the WQS method that models spatially varying chemical mixture effects called local weighted quantile sum (LWQS) regression, and assess through a simulation study its ability to identify important environmental risk factors over space. We use two different approaches to estimate the LWQS model based on variable subspaces. One uses an ensemble of variable subsets of the same size, and the other selects the best subset over a range of candidate subset sizes according to the model goodness-of-fit. We assess the performance of both estimation methods in simulated scenarios that incorporate increasingly complex levels of spatial dependency in the model, and consider correlation patterns from observed exposure data. The results demonstrate that LWQS has the ability to replicate spatially dependent mixture effects and can correctly identify important exposures in a mixture of environmental chemicals. In all scenarios, the best subset approach correctly chose an index containing only the important chemicals and improved on the accuracy of the chemical importance weights in comparison with the ensemble solutions. Future work will evaluate if the ensemble subset approach has better relative performance with larger chemical mixtures of highly correlated components.

Download or read book Chemical Carcinogenesis written by Trevor M. Penning and published by Springer Science & Business Media. This book was released on 2011-03-03 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume will provide a contemporary account of advances in chemical carcinogenesis. It will promote the view that it is chemical alteration of the DNA that is a route cause of many cancers. The multi-stage model of chemical carcinogenesis, exposure to major classes of human carcinogens and their mode-of-action will be a focal point. The balance between metabolic activation to form biological reactive intermediates and their detoxification, ensuing DNA-lesions and their repair will be profiled. It will describe the chemical changes that occur in DNA that result from endogenous insults including epigenetic changes that lead to gene silencing. It will describe major mechanisms of mutagenesis, affects on tumor suppressor genes and proto-oncogenes, and how cell-cycle check points can be by-passed by the "stealth-like" properties of chemical carcinogens. Environmental agents that can promote tumor formation will be discussed. The monograph will have wide appeal as a knowledge base for graduate students, post-doctoral fellows and faculty interested in this aspect of cancer causation and research.
