DDT is a pesticide that was once widely used to control insects. Both DDD and DDE are breakdown products of DDT. This profile includes: (1) The examination, summary, and interpretation of available toxicologic info. and epidemiologic evaluations on DDT/DDD/DDE to ascertain the levels of significant human exposure for the substance and the associated chronic health effects; (2) A determination of whether adequate info. on the health effects of DDT/DDD/DDE is available to determine levels of exposure that present a significant risk to human health of chronic health effects; and (3) Identification of toxicologic testing needed to identify the types or levels of exposure that may present significant risk of adverse health effects in humans.

This is the first book to set out a full range of research strategies for evaluating the clinical practice of acupuncture. Leading acupuncturists and researchers with international reputations share their expertise. They illustrate their descriptions with practical examples of what has worked and what has not. It outlines many of the key challenges in the field. These challenges relate to the nature of acupuncture and the gap between current research evidence and the actual experiences of acupuncturists in the field. By focusing the chapters on key research questions, rather than methods, the book has a user-friendly feel. Each chapter is easily accessible with brief explanations of research designs as well as vignettes of relevant past research. The book is based on a deep understanding of acupuncture, with its inherent complexity in practice, whether based on traditional principles or more modern concepts. By incorporating a more sophisticated understanding of the field, this book details a range of strategies aiming to develop the evidence base with the utmost rigour. It is the first book on acupuncture research to take this unique view, integrating the very best of evidence-based medicine with a genuine sensitivity to the discipline of acupuncture, from its traditional and holistic roots to its more modern interpretations.

The Department of Toxic Substances Control (DTSC) of the State of California Environmental Protection Agency is in the process of complying with the Regulatory Structure Update. The Regulatory Structure Update is a comprehensive review and refocusing of California's system for identifying and regulating management of hazardous wastes. As part of this effort, the DTSC proposes to change its current waste classification system that categorizes wastes as hazardous or nonhazardous based on their toxicity. Under the proposed system there would be two risk-based thresholds rather than the single toxicity threshold currently used to distinguish between the wastes. Wastes that contain specific chemicals at concentrations that exceed the upper threshold will be designated as hazardous; those below the lower threshold will be nonhazardous; and those with chemical concentrations between the two thresholds will be "special" wastes and subject to variances for management and disposal. The proposed DTSC system combines toxicity information with short or long-term exposure information to determine the risks associated with the chemicals. Under section 57004 of the California Health and Safety Code, the scientific basis of the proposed waste classification system is subject to external scientific peer review by the National Academy of Sciences, the University of California, or other similar institution of higher learning or group of scientists. This report addresses that regulatory requirement.
