This book discusses a wide range of health-related mining issues, with particular reference to occupational diseases, metal toxicity, postural injuries in miners, modern fire safety controls, noise-induced hearing loss prevention, and noise mapping. Mining plays a central role in the development of modern civilization. By providing the essential raw materials, mining ensures progress, safety, and comfort of people. However, this necessary activity comes with several woes, the most important of which are occupational health hazards. Mines act as sources of constant danger and risk to the miners irrespective of the scale of mining, such as large-scale industrial mining or small-scale artisanal mining. Not only are there accidents, but continuous exposure to dust, metal toxicity, hazardous gases and fumes, and loud noises, giving rise to a variety of diseases to mine workers. The comprehensive coverage of issues and the case studies will make this book an essential reference and critical reading. Medical geology is a necessary discipline in earth sciences. Unfortunately, not much literature is available on this subject. Therefore, this book is essential for practicing engineers and supervisors in mines, health and safety professionals, researchers, and mining industry students.

This book provides an overview of Data Monitoring Committees(DMC) - what was done in the past, what is currently being done, and thoughts on improvements for the future. Previous works focused primarily on large cardiovascular studies (where DMCs originated more than 30 years ago) but updated references are needed that discuss smaller, more flexible studies in areas such as oncology. The authors have attended ~800 DMC meetings from ~200 distinct studies across all areas of clinical studies (oncology, rheumatology, rare diseases, cardiology, immunology, etc.) This wide range of expertise will be used, as well as the expertise that comes from working with virtually every large biotechnology and pharmaceutical company and CRO for DMC work. The reader of the book will know when DMCs are needed or helpful, how to form the DMC, how to work with external CROs and with sponsor teams and the DMC to create needed DMC outputs, how the DMC meetings are conducted, and - especially for DMC members - what are considerations within the Closed Session to review safety/efficacy outputs to assess risk/benefit to make appropriate recommendations that protect the patient safety and trial integrity.This is a practical hands-on book on how to decide if a DMC is necessary, how to form the DMC, how to expertly create the necessary materials for the DMC and have smooth running DMC meetings. There is no specialized training in school about how DMCs work - frequently people may have been in industry for many years without ever needing to work with a DMC. This book is the helpful reference for those new to these DMCs. The DMC work is critical to be correctly implemented as the impact of DMC activity on safeguarding the trial is so important.This book provides the following:Provides thorough instructions on the steps needed to form and implement a Data Monitoring Committee for clinical trial evaluation;Includes practical and hands-on information on DMC implementation;Discusses a wide range of clinical trial ¿ by phase and therapeutic area.

This book focuses on the topic of ecotoxicology of aquatic macrophytes and is wide ranging, including the use of macrophytes for remediation of contaminated sites. Many human activities are threats to the equilibrium of natural ecosystems. Pollution from point and non-point sources can be assessed using a variety of techniques, such as biomonitoring, biomarkers and biosensors. In aquatic ecosystems, biomonitoring of pollutants is mostly conducted by analysis of the tissues of invertebrates and fishes, and biomarker studies are also more widely applied to animals rather than in plants. Aquatic macrophytes occupy a key niche in aquatic ecosystems and provide a range of ecosystem services. In addition to their role in primary production, vegetation plays a key role in the cycling and retention of nutrients and generally acts as a sink for pollutants. Therefore, because of their importance to aquatic ecosystems, more attention should be paid to understanding the fate of pollutants and to developing methods to evaluate the health status of macrophytic plants in freshwater, marine and estuarine environments.

"e;Doubt is our product,"e; a cigarette executive once observed, "e;since it is the best means of competing with the 'body of fact' that exists in the minds of the general public. It is also the means of establishing a controversy."e;In this eye-opening expose, David Michaels reveals how the tobacco industry's duplicitous tactics spawned a multimillion dollar industry that is dismantling public health safeguards. Product defense consultants, he argues, have increasingly skewed the scientific literature, manufactured and magnified scientific uncertainty, and influenced policy decisions to the advantage of polluters and the manufacturers of dangerous products. To keep the public confused about the hazards posed by global warming, second-hand smoke, asbestos, lead, plastics, and many other toxic materials, industry executives have hired unscrupulous scientists and lobbyists to dispute scientific evidence about health risks. In doing so, they have not only delayed action on specific hazards, but they have constructed barriers to make it harder for lawmakers, government agencies, and courts to respond to future threats. The Orwellian strategy of dismissing research conducted by the scientific community as "e;junk science"e; and elevating science conducted by product defense specialists to "e;sound science"e; status also creates confusion about the very nature of scientific inquiry and undermines the public's confidence in science's ability to address public health and environmental concerns Such reckless practices have long existed, but Michaels argues that the Bush administration deepened the dysfunction by virtually handing over regulatory agencies to the very corporate powers whose products and behavior they are charged with overseeing. In Doubt Is Their Product Michaels proves, beyond a doubt, that our regulatory system has been broken. He offers concrete, workable suggestions for how it can be restored by taking the politics out of science and ensuring that concern for public safety, rather than private profits, guides our regulatory policy. Named one of the best Sci-Tech books of 2008 by Library Journal!

Toxische Stoffe sind ubiquitär und auf Grund hochempfindlicher Analysenmethoden in allen umweltrelevanten Matrices, biologischen Materialien und Lebensmitteln nachweisbar. Die Frage ist, wann und in welchen Konzentrationen sind sie für den Menschen gesundheitsschädlich oder sogar tödlich. Rauchen, Alkohol- und Tablettenmissbrauch sind die Klassiker für Intoxikationen. Aber wie (stark) wirken Toxine, Drogen, Dopingsubstanzen oder toxische Kampfstoffe wie Nowitschok? Die Mechanismen der toxischen Wirkungen sind sehr verschieden ¿ ist eine Kohlenmonoxid-Vergiftung durch wesentlich höhere Bindungskraft von CO im Vergleich zum O2 an das Fe-Atoms des Hämoglobins relativ einfach erklärbar, so wirken andere Noxen innerhalb komplexer Reaktionen und auf molekularer Ebene. Das cancerogene Benzo(a)pyren ist selbst nicht toxisch ¿ erst wenn es über mehrere Stufen zum Diol-Epoxid metabolisiert wird, erfolgt die Schädigung der DNA. Die 210 unterschiedlichen Dioxine besitzen extrem verschiedene Toxizitäten ¿ durch Aktivierung eines Aryl-Hydrocarbon-Rezeptors werden Reaktionen ausgelöst, die zu Intoxikationen führen. Das Tetrodotoxins des Kugelfisches blockiert die spannungsaktiven Na-Kanäle in den Neuronen und führt zu Lähmungen. Chemische Kampfstoffe wie Nowitschok (Fall Nawalny) blockieren die Acetylcholinesterase. Weitere wissenschaftliche Erklärungen beinhalten, warum Zyankali Lactozidose bewirkt, weshalb Cadmium zu Osteoporose führen kann oder wie Methanol-Abusus blind macht? Spannende Antworten erwarten wir auch in Zukunft: Welche Langzeitfolgen können durch Tattoos entstehen oder setzt sich die E-Zigarette durch?

Since its advent, nanotechnologies are considered key enabling technologies that take advantage of a wide array of nanomaterials (NMs) for biomedical and industrial applications generating significant societal and economic benefits. However, such innovation increases human exposure to these substances through inhalation, ingestion or dermal contact raising public health concerns. Furthermore, the NMs' specific physicochemical properties, that confer them unique beneficial characteristics, can also elicit nano-bio interactions leading to toxicity and concerns for public health. In addition, such properties can be affected by the surrounding matrix, particularly when incorporated in complex matrices such as food products, leading to secondary features potentially more relevant than primary characteristics for determining their toxicological outcome. These nano specific issues raise the question of whether the NMs may produce adverse outcomes that are not accounted for when using conventional toxicological approaches to assess their safety.Such uncertainties about the safety of NMs for human health and the environment may hamper a faster and more widespread exploration of their potentials. In response, the NMs definition has evolved, and nanotoxicology has developed towards new and more integrative approach methods to support regulatory and policy actions.This book provides a perspective on recent developments in the synthesis, application, and characterization of NMs and the related nanotechnologies, focusing on nanotoxicology for their accurate safety assessment early in the product development stage. The use of complex in vitro models, including multicellular systems and organoids, and "e;omics-based"e; approaches, such as transcriptomics or epigenomics, have greatly contributed to an in-depth understanding of the cellular and molecular mechanisms behind some NMs toxicity. Such mechanistic knowledge is equally addressed in this book and has set the basis for a predictive nanotoxicology approach building on adverse outcome pathways. In addition, considering the knowledge provided by the above-mentioned approaches, insights into risk assessment, standardization, and regulation of NMs are also included.Incorporating adequate nanosafety assessment early in the life-cycle of NMs will allow the implementation of the safe and sustainable-by-design paradigm enabling safety to keep pace with innovation.Chapters 10 and 15 are available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.
