Electron Microscopy In Forensic Occupational And Environmental Health Sciences

Forensic, Occupational and Environmental Health Sciences are identification sciences dealing with criminal and delicate societal problems for which scanning electron microscopy (SEM) with energy dispersive x-rays (EDAX) and analytical transmission electron microscopy (TEM) are providing increasingly definitive solutions. This is particularly true in the area of particulates. However, electron microscopists working independently in these three related fields are often called upon to identify particulates which have been well characterized by microscopists in one of the other fields of study. Exchange of information on particulate identification and techniques for analyzing new unusual samples has been difficult between the three disciplines. For example, automated search and identification of particulates has become a standard procedure in environmental and occupational health. The procedure, however, has yet to find its way into forensic laboratories for analysis of gunshot residue particles. This volume represents a beginning for collaboration and exchange of ideas between such areas of study with diverse interests but similar analytical problems. It is virtually certain that this effort will also interest other electron microscopists in some novel scientific problems with criminal and societal relevance. The volume presents full-length articles of several invited speakers and participants at the "Forensic, Occupational and Environmental Health Sciences" Symposium held as a part of the EMSA-MAS Joint Annual Meeting, 5-9 August 1985, Louisville, Kentucky. Extended 2-4 page abstracts of these presentations have been published in the EMSA Proceedings (1985).

The most exhaustive book on forensic dentistry, the fourth edition of this volume covers the latest advances in the field, including regulations affecting forensic dental practice and procedures in light of the Health Insurance Portability and Accessibility Act, updated ABFO guidelines, and new digital radiographic and photographic developments.

An applied approach to teaching forensic microscopy in educational settings, featuring new experiments and an up-to-date overview of the field Practical Forensic Microscopy: A Laboratory Manual, 2nd Edition, is a unique resource that brings the microscopic procedures used by real-world forensic investigators to the college laboratory, providing hands-on knowledge of the microscopes and microscopic techniques used in the field. Presenting a balanced, skills-based approach to the subject, this student-friendly lab manual contains dozens of experiments designed to cover the various microscopic evidence disciplines, including examinations of fingerprints, firearm, toolmark, shoeprint and tire impressions, gunshots, fibers, soil, glass breakage, drugs, semen, and human hair. The second edition includes revised and updated experiments that reflect current technologies and techniques used in forensic science, including new experiments examining plastic film, food condiments, feathers, building materials, explosive residue, cigarette butts and more. Each chapter includes a list of simple objectives for the experiment, a general overview of the topic, further readings, and selected references. The manual contains worksheets and templates for students to use when compiling analytical results. The concluding chapter features an innovative case scenario that requires students to analyze items of evidence, complete a laboratory report, reach a conclusion, and present their findings. This popular lab manual: Teaches practical forensic microscopy skills through hands-on experiments and engaging practical activities Covers a wide range of microscopes and forensic tools, including stereomicroscopes, ocular micrometers, and fluorescence, polarized light, and phase contrast microscopes Explains simple stereomicroscopic techniques for analyzing various types of common forensic evidence Includes more complex procedures for examining biological, drug, and trace evidence Discusses laboratory safety, microscope maintenance, and the Micro Kit Written by an author with years of academic and professional experience, Practical Forensic Microscopy: A Laboratory Manual, 2nd Edition, is a must-have companion for any college-level forensic science course with a laboratory component, and is a useful supplement for related courses that cover microscopy and the principles of forensic lab procedures.

Forensic Microscopy: Truth Under the Lenses provides an overview and understanding of the various types of microscopes and their techniques employed in forensic science. The book emphasizes both the theoretical and practical aspects of microscopy to enrich the reader’s understanding of the various tools, techniques, and utility—including strengths and weaknesses—of types of microscopes in analyzing certain forms of evidence. The book begins with the history of microscopes, the basic optics for microscopy, then moves to advanced microscopies such as electron microscopes and atomic force microscopes. In addition to the various types of microscopes and how to use and best utilize them, the book looks at the analysis of specific types of evidence, including hair, fiber, fingerprint, body fluids, tool marks, ink, pollen grains, spores, diatoms, bullets, cartridges, among other evidence types. Since forensic science is an applied, hands-on discipline, the book includes both a theoretical and a practical approach to the topic. Key Features: Addresses simple to advanced microscopy techniques for the effective analyses of trace evidence Pairs chapters on a particular type of microscopy, explaining it thoroughly, before delving into specific usage for forensic applications Presents theories and as well as real-world application of concepts Provides abundant micro-photographs, including graphical representations and flow charts, to illustrate concepts clearly Forensic Microscopy serves as a helpful reference for undergraduate and postgraduate students in forensic science, forensic biology, forensic chemistry and related programs. It is also recommended for research students, academicians, technicians, industry and laboratory professionals working on trace evidence analysis.

Settled Asbestos Dust Sampling and Analysis compiles the most significant data on asbestos in settled dust. This ready reference presents an analysis of settled dusts and surface particles of all sizes for asbestosthat is useful for qualitative and quantitative assessment and helps to determine the source of fibers. The main scope of this reference includes sample collection, sample analyses, and interpretation of settled dust data, as well as the use of such data for purposes including asbestos abatement projects and in-place management programs. Sections on lead and other particulates are also included.
