Advances in molecular biology and toxicology are paving the way for major improvements in the evaluation of the hazards posed by the large number of chemicals found at low levels in the environment. The National Research Council was asked by the U.S. Environmental Protection Agency to review the state of the science and create a far-reaching vision for the future of toxicity testing. The book finds that developing, improving, and validating new laboratory tools based on recent scientific advances could significantly improve our ability to understand the hazards and risks posed by chemicals. This new knowledge would lead to much more informed environmental regulations and dramatically reduce the need for animal testing because the new tests would be based on human cells and cell components. Substantial scientific efforts and resources will be required to leverage these new technologies to realize the vision, but the result will be a more efficient, informative and less costly system for assessing the hazards posed by industrial chemicals and pesticides.

The National Toxicology Program (NTP) conducted a systematic review of the evidence of adverse neurodevelopmental and cognitive effects of fluoride exposure. NTP's conclusions are summarized in the monograph Systematic Review of Fluoride Exposure and Neurodevelopmental and Cognitive Health Effects. At the request of NTP, a committee convened by the National Academies reviewed their monograph to ensure the integrity of that report. It is important to note that the committee was tasked with reviewing the monograph and focused its efforts on evaluating whether evidence as presented in the monograph supported NTP's conclusions. Thus, it did not conduct its own independent evaluation of the evidence, and it did not conduct a data audit. However, it did review some key literature to enable its review of the monograph. Review of the Draft NTP Monograph contains findings and suggestions for improvements and some overarching findings concerning methods, assessment of animal and human evidence, and NTP's hazard conclusion.

Genetic Toxicology Testing: A Laboratory Manual presents a practical guide to genetic toxicology testing of chemicals in a GLP environment. The most commonly used assays are described, from laboratory and test design to results analysis. In a methodical manner, individual test methods are described step-by-step, along with equipment, suggested suppliers, recipes for reagents, and evaluation criteria. An invaluable resource in the lab, this book will help to troubleshoot any assay problems you may encounter to optimise quality and efficiency in your genetic toxicology tests. Genetic Toxicology Testing: A Laboratory Manual is an essential reference for those new to the genetic toxicology laboratory, or anyone involved in setting up their own. - Offers practical and consistent guidance on the most commonly-performed tests and procedures in a genetic toxicology lab - Describes standard genetic toxicology assays, their methodology, reagents, suppliers, and analysis of their results - Includes guidance on general approaches: formulation for in vitro assays, study monitoring, and Good Laboratory Practice (GLP) - Serves as an essential reference for those new to the genetic toxicology laboratory, or anyone involved in setting up their own lab

Most people associate fluoride with the practice of intentionally adding fluoride to public drinking water supplies for the prevention of tooth decay. However, fluoride can also enter public water systems from natural sources, including runoff from the weathering of fluoride-containing rocks and soils and leaching from soil into groundwater. Fluoride pollution from various industrial emissions can also contaminate water supplies. In a few areas of the United States fluoride concentrations in water are much higher than normal, mostly from natural sources. Fluoride is one of the drinking water contaminants regulated by the U.S. Environmental Protection Agency (EPA) because it can occur at these toxic levels. In 1986, the EPA established a maximum allowable concentration for fluoride in drinking water of 4 milligrams per liter, a guideline designed to prevent the public from being exposed to harmful levels of fluoride. Fluoride in Drinking Water reviews research on various health effects from exposure to fluoride, including studies conducted in the last 10 years.
