This book was released on 2012 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until recently, very little research has been conducted to assess the potential human health hazards associated with engineered nanomaterials (ENMs). In-vitro high-throughput screening (HTS) assays for the assessment of engineered nanomaterials provide new opportunities to learn how these particles interact at the cellular level, and may aid in reducing the demand for in-vivo testing. The large number of potential factors that could link nanomaterials to adverse human health impacts, create an imperative need to develop a stronger foundation for quantitative risk assessment in nanotoxicology. In this dissertation we propose a probability model for the analysis of high-throughput cellular assays. In particular, we develop a method that builds a balance between model complexity and interpretability as a tool to be used by subject-matter specialists for assessing cytotoxicity. The resulting multivariate surface-response model allows for joint inference on dose and time kinetics, and associated classical risk assessment parameters of interest. We illustrate the proposed methodology by profiling a multivariate screening study of eight metal-oxide nanomaterials. Next, we present loss-function-based methods for the hazard ranking of engineered nanomaterials. Specifically, we provide a decision-making tool for prioritizing extensive in-vivo testing of emerging nanomaterials. The proposed framework allows for the aggregation of ranks across different sources of evidence while allowing for differential weighting of this evidence based on its reliability and importance in risk ranking. We illustrate the methodology by ranking particles from a multivariate cytotoxicity screening study of eight metal oxides, conducted in two human cell-lines. Finally, we propose methodology for modeling the relationship between physicochemical properties of ENMs and their observed cytotoxicity, as an initial step in the development of a framework for predictive nanotoxicology. In particular, the proposed approach introduces a new measure of toxicity that is seamlessly integrated into a multi-dimensional model that accounts for dose and duration kinetics jointly using a flexible smooth surface fit. Moreover, the designed approach is appropriate for small sample size, and includes data integration and a framework for advanced dimension reduction through variable selection. The proposed method was applied to a library of 24 engineered nanomaterials.

Download or read book Toxicity Testing in the 21st Century written by National Research Council and published by National Academies Press. This book was released on 2007-10-05 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in molecular biology and toxicology are paving the way for major improvements in the evaluation of the hazards posed by the large number of chemicals found at low levels in the environment. The National Research Council was asked by the U.S. Environmental Protection Agency to review the state of the science and create a far-reaching vision for the future of toxicity testing. The book finds that developing, improving, and validating new laboratory tools based on recent scientific advances could significantly improve our ability to understand the hazards and risks posed by chemicals. This new knowledge would lead to much more informed environmental regulations and dramatically reduce the need for animal testing because the new tests would be based on human cells and cell components. Substantial scientific efforts and resources will be required to leverage these new technologies to realize the vision, but the result will be a more efficient, informative and less costly system for assessing the hazards posed by industrial chemicals and pesticides.

Download or read book Computational Nanotoxicology written by Agnieszka Gajewicz and published by CRC Press. This book was released on 2019-11-13 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of computational methods that support human health and environmental risk assessment of engineered nanomaterials (ENMs) has attracted great interest because the application of these methods enables us to fill existing experimental data gaps. However, considering the high degree of complexity and multifunctionality of ENMs, computational methods originally developed for regular chemicals cannot always be applied explicitly in nanotoxicology. This book discusses the current state of the art and future needs in the development of computational modeling techniques for nanotoxicology. It focuses on (i) computational chemistry (quantum mechanics, semi-empirical methods, density functional theory, molecular mechanics, molecular dynamics), (ii) nanochemoinformatic methods (quantitative structure–activity relationship modeling, grouping, read-across), and (iii) nanobioinformatic methods (genomics, transcriptomics, proteomics, metabolomics). It reviews methods of calculating molecular descriptors sufficient to characterize the structure of nanoparticles, specifies recent trends in the validation of computational methods, and discusses ways to cope with the uncertainty of predictions. In addition, it highlights the status quo and further challenges in the application of computational methods in regulation (e.g., REACH, OECD) and in industry for product development and optimization and the future directions for increasing acceptance of computational modeling for nanotoxicology.

This book was released on 2012-05-09 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nanotechnology sector, which generated about $225 billion in product sales in 2009, is predicted to expand rapidly over the next decade with the development of new technologies that have new capabilities. The increasing production and use of engineered nanomaterials (ENMs) may lead to greater exposures of workers, consumers, and the environment, and the unique scale-specific and novel properties of the materials raise questions about their potential effects on human health and the environment. Over the last decade, government agencies, academic institutions, industry, and others have conducted many assessments of the environmental, health, and safety (EHS) aspects of nanotechnology. The results of those efforts have helped to direct research on the EHS aspects of ENMs. However, despite the progress in assessing research needs and despite the research that has been funded and conducted, developers, regulators, and consumers of nanotechnology-enabled products remain uncertain about the types and quantities of nanomaterials in commerce or in development, their possible applications, and their associated risks. A Research Strategy for Environmental, Health, and Safety Aspects of Engineered Nanomaterials presents a strategic approach for developing the science and research infrastructure needed to address uncertainties regarding the potential EHS risks of ENMs. The report summarizes the current state of the science and high-priority data gaps on the potential EHS risks posed by ENMs and describes the fundamental tools and approaches needed to pursue an EHS risk research strategy. The report also presents a proposed research agenda, short-term and long-term research priorities, and estimates of needed resources and concludes by focusing on implementation of the research strategy and evaluation of its progress, elements that the committee considered integral to its charge.

Download or read book Green Toxicology written by Alexandra Maertens and published by Royal Society of Chemistry. This book was released on 2022-02-01 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Green toxicology is an integral part of green chemistry. One of the key goals of green chemistry is to design less toxic chemicals. Therefore, an understanding of toxicology and hazard assessment is important for any chemist working in green chemistry, but toxicology is rarely part of most chemists' education. As a consequence, chemists lack the toxicological lens necessary to view chemicals in order to design safer substitutions. This book seeks to fill that gap and demonstrate how a basic understanding of toxicology, as well as the tools of in silico and in vitro toxicology, can be an integral part of green chemistry. R&D chemists, product stewards, and toxicologists who work in the field of sustainability, can all benefit from integrating green toxicology principles into their work. Topics include in silico tools for hazard assessment, toxicity testing, and lifecycle considerations, this book aims to act as a bridge between green toxicologists and green chemists.
