Description

Written specifically for the undergraduate course in Forensic Chemistry, Bell’s Forensic Chemistry provides a solid foundation for basic chemistry, introducing chemical concepts and practices from a forensic perspective (including multivariate statistics, quality assurance/quality control, and protocols used in working forensic laboratories). It offers students insight into the legal context in which forensic chemistry is conducted, the variety of types of samples and matrices, and extensive use of instrumentation they will likely encounter in the lab and future professions.

Features

  • A comprehensive section on essential elements delves into the aspects of study unique to forensic chemistry, including: types of samples and how they are prepared; acid/base chemistry of drugs; solubility; preparations; presumptive testing, and a detailed discussion of microscopy, a fundamental tool of the forensic chemist.
  • Extensive coverage of drug analysis presents an overview of forensic pharmacology, including physical and biological evidence, toxicology, and aspects of drug analysis critical to reconstructing a crime scene.
  • Broad coverage of chemical analysis of physical evidence addresses the analysis of evidence related to combustion; polymers; paper and inks, and paints and coatings.
  • Extensive problem sets in each chapter include chapter-based questions, integrative queries that require further research, and “Food for Thought” questions drawn from the experience of practicing forensic chemists.
  • Applying the Science boxes are drawn from current literature and working forensic laboratories. These provide context for chapter material, linking coursework to current research and forensic casework.
  • Exhibits include contemporary and historical cases, developments, and information pertinent to the professional world are provided to add context to the topics throughout the text.

New to this Edition

  • NEW! N ew Applying the Science boxes, including Sampling and Method Uncertainty in Urine (Chapter 4) and You Are What You Eat (Chapter 6), provide the context for the material presented and integrate several aspects of forensic chemistry in one place.
  • NEW! New Exhibit boxes such as Tylenol and Toxicity (Chapter 9) and Trace and Transfer Evidence (Chapter 17) provide a link to the professional world.
  • NEW! T o reflect the new research and development recently made in Forensic chemistry, three new chapters have been added:
    • Reporting Defensible Uncertainty and Obtaining Representative Samples (Chapter 4) addresses recent interest in the forensic community on how to improve forensic science in the future.
    • Forensic Toxicology (Chapter 10): engages students in cutting-edge research relevant to the field.
    • Firearms and Associated Chemical Evidence (Chapter 13) provides critical discussion of extensively reworked and updated content on combustion chemistry in this revision.
  • NEW! Online Laboratory Manual is now available on the TheChemPlace (www.chemplace.com):
    • The labs are designed to ensure that they can be performed with typical chemical instrumentation and reagents, including drugs and metabolites. The content is tied directly to specific sections of the text and includes example student results.
    • Emphasis on microscopy is decreased, with greater emphasis placed on forensic toxicology, metabolism, and drug analysis. Existing labs focusing on microscopy have been replaced with laboratories in the area of drug metabolism, solubility as a function of pH, and acid/base extractions.
    • Also included on the ChemPlace for this edition are Virtual Forensic Science Labs for topics including Forensic Glass Analysis, Drug Identification, and Arson Detection. These highly interactive exercises give students the virtual experience of working in forensics laboratory.
  • NEW! Several new sections have been added, including Metrology and Measurement (2.1), Absorption (9.4), and Forensic Analysis of Explosives (12.3).
  • Several new questions have been added throughout the text, with an emphasis on quantitative problems.
  • References have been updated and outdated sidebars have been removed and replaced with current information to reflect new developments in this field.
