Introduction: Assessing Toxic Substances Through a Glass Darkly
This chapter provides an overview of the topics discussed in the book and likens the assessment of toxic substances to the experience of peering through a glass darkly. The work is divided into five main chapters and these chapters give an exploration of the scientific background necessary for understanding the subject. The book examines the practice of predicting risks from animal bioassays and addresses the normative implications of the scientific uncertainties in risk assessment. In addition, the book examines problems in the statistics of human epidemiological studies and animal bioassay and considers practical evidence-gathering problems, theoretical difficulties, and traditional practices in interpreting epidemiological studies and offers an alternative to traditional practices.
