This volume of the IARC Monographs provides an assessment of the carcinogenicity of fluoro-edenite fibrous amphibole, silicon carbide fibres and whiskers, and carbon nanotubes, including single-walled and multiwalled types. None of these agents had been assessed previously by the IARC Monographs Working Group. The Working Group relied mainly on epidemiological studies to evaluate the carcinogenic hazard to humans exposed to fluoro-edenite fibrous amphibole, an environmental contaminant that was reported to cause mesothelioma in the regional population of Biancavilla, Sicily, Italy. Silicon carbide fibres are by-products of the manufacture of silicon carbide particles by the Acheson process; silicon carbide whiskers are produced by other processes. The evaluations of the fibres and of the occupational exposures associated with the Acheson process were mainly based on epidemiological studies, whereas the assessment of the whiskers--in the absence of epidemiological--was based on carcinogenicity bioassays and consideration of their physical properties. In view of the absence of epidemiological studies on carbon nanotubes and the limited information available from mechanistic data, the evaluations of single-walled and multiwalled carbon nanotubes relied essentially on carcinogenicity bioassays.

Health and Environmental Safety of Nanomaterials addresses concerns about the impact of nanomaterials on the environment and human health, and examines the safety of specific nanomaterials. Understanding the unique chemical and physical properties of nanostructures has led to many developments in the applications of nanocomposite materials. While these materials have applications in a huge range of areas, their potential for toxicity must be thoroughly understood. Part one introduces the properties of nanomaterials, nanofillers, and nanocomposites, and questions whether they are more toxic than their bulk counterparts. Part two looks at the release and exposure of nanomaterials. The text covers sampling techniques and data analysis methods used to assess nanoparticle exposure, as well as protocols for testing the safety of polymer nanocomposites. It explains characterization techniques of airborne nanoparticles and life cycle assessment of engineered nanomaterials. Part three focuses on the safety of certain nanomaterials, including nanolayered silicates, carbon nanotubes, and metal oxides. In particular, it explores the potential ecotoxicological hazards associated with the different structures of carbon nanotubes and the safe recycling of inorganic and carbon nanoparticles. The final two chapters address the risks of nanomaterials in fire conditions: their thermal degradation, flammability, and toxicity in different fire scenarios. This is a scientific guide with technical background for professionals using nanomaterials in industry, scientists, academicians, research scholars, and polymer engineers. It also offers a deep understanding of the subject for undergraduate and postgraduate students. - Introduces the properties of nanomaterials, nanofillers, and nanocomposites, and questions whether they are more toxic than their bulk counterparts - Covers sampling techniques and data analysis methods used to assess nanoparticle exposure, as well as protocols for testing the safety of polymer nanocomposites - Explores the potential ecotoxicological hazards associated with the different structures of carbon nanotubes and the safe recycling of inorganic and carbon nanoparticles

This edited volume discusses the short-term inhalation study (STIS) and intratracheal administration, the two major in vivo inhalation-toxicity screening methods, which play an important role in efficient hazard evaluation. It also provides a general overview of the inhalation toxicity of nanomaterials and related issues. For each screening method, it provides up-to-date information on the test procedures, interpretation of the test results, useful applications, and related technologies. In view of the increasing variety of nanomaterials in practical use, the book offers a basis for building a framework for grouping and read-across assessments of nanomaterials. With contributions by academic and industrial experts, In vivo Inhalation Toxicity Screening Methods for Manufactured Nanomaterials is a pragmatic reference resource for readers who are responsible for assessing the safety of nanomaterials in R&D and business, as well as researchers.

This book offers an updated review of malignant mesothelioma, including the latest advances in our understanding of its genetic control and molecular biology, as well as pre-clinical and clinical research. It also presents state-of-the-art diagnostic approaches and therapeutic options, and an open discussion on the future prospects for patient management. Malignant mesothelioma is an enormous global health problem related to asbestos exposure. Despite the best efforts of scientists and oncologists, the prognosis for those affected remains poor. Due to anatomical characteristics and non-specific symptoms, the diagnosis of mesothelioma at an early stage is often difficult, while surgery and radiotherapy are only of limited use, even if some multimodality approaches seem promising. In turn, medical treatments are sometimes successful in tumor control, but have little impact on overall survival. However, advances in our understanding of the disease’s biology, together with the availability of new drugs and combinations, make mesothelioma an essential and highly topical field for pre-clinical and clinical studies. This book is subdivided into four parts: epidemiology and preclinical data, diagnosis, therapy, and extrathoracic mesothelioma. It highlights the progress made in a variety of areas – e.g. in vitro and in vivo experimental models, genetics, environment, biomarkers, targeting agents, immunotherapy, metabolic imaging and ongoing clinical trials – and describes the standard clinical management of mesothelioma patients, including those with extra-thoracic localizations. Given its scope, the book offers an invaluable tool for researchers, oncologists and clinicians alike.
