Download or read book Submarine Exposure Guidance Levels for Selected Hydrofluorocarbons written by National Research Council and published by National Academies Press. This book was released on 2000-07-01 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of the effort to phase out the use of stratospheric ozone-depleting substances, such as chlorofluorocarbons (CFCs), the U.S. Navy is considering hydrofluorocarbons (HFCs) as replacements for the CFC refrigerants used aboard its submarines. Before using the HFCs, the Navy plans to set emergency exposure guidance levels (EEGLs) and continuous exposure guidance levels (CEGLs) to protect submariners from health effects that could occur as a result of accidental releases or slow leaks. In this report, the Subcommittee on Exposure Guidance Levels for Selected Hydrofluorocarbons of the National Research Council's (NRC 's) Committee on Toxicology independently reviews the scientific validity of the Navy's proposed 1-hr and 24-hr EEGLs and 90-day CEGLs for two of the candidate refrigerants-HFC-236fa and HFC-404a. In addition, the subcommittee reviews the the EEGLs and CEGL for HFC-23, one of the combustion products of HFC-236fa. This NRC report is intended to aid the Navy in using HFCs safely.

Download or read book Standing Operating Procedures for Developing Acute Exposure Guideline Levels for Hazardous Chemicals written by National Research Council and published by National Academies Press. This book was released on 2001-06-25 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Standing Operating Procedures for Developing Acute Exposure Guideline Levels for Hazardous Chemicals contains a detailed and comprehensive methodology for developing acute exposure guideline levels (AEGLs) for toxic substances from inhalation exposures. The book provides guidance on what documents and databases to use, toxicity endpoints that need to be evaluated, dosimetry corrections from animal to human exposures, selection of appropriate uncertainty factors to address the variability between animals and humans and within the human population, selection of modifying factors to address data deficiencies, time scaling, and quantitative cancer risk assessment. It also contains an example of a summary of a technical support document and an example of AEGL derivation. This book will be useful to persons in the derivation of levels from other exposure routesâ€"both oral and dermalâ€"as well as risk assessors in the government, academe, and private industry.

Download or read book Acute Exposure Guideline Levels for Selected Airborne Chemicals written by National Research Council and published by National Academies Press. This book was released on 2002-10-07 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews toxicity documents on five chemicals that can be released in the air from accidents at chemical plants, storage sites, or during transportation. The documents were prepared by the National Advisory Committee on Acute Exposure Guideline Levels for Hazardous Substances and were evaluated for their scientific validity, comprehensives, internal consistency, and conformance to the 1993 guidelines report.

Download or read book Essential Chemistry for Formulators of Semisolid and Liquid Dosages written by Vitthal S. Kulkarni and published by Academic Press. This book was released on 2015-10-15 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: A needed resource for pharmaceutical scientists and cosmetic chemists, Essential Chemistry for Formulators of Semisolid and Liquid Dosages provides insight into the basic chemistry of mixing different phases and test methods for the stability study of nonsolid formulations. The book covers foundational surface/colloid chemistry, which forms the necessary background for making emulsions, suspensions, solutions, and nano drug delivery systems, and the chemistry of mixing, which is critical for further formulation of drug delivery systems into semisolid (gels, creams, lotions, and ointments) or liquid final dosages. Expanding on these foundational principles, this useful guide explores stability testing methods, such as particle size, rheological/viscosity, microscopy, and chemical, and closes with a valuable discussion of regulatory issues. Essential Chemistry for Formulators of Semisolid and Liquid Dosages offers scientists and students the foundation and practical guidance to make and analyze semisolid and liquid formulations. - Unique coverage of the underlying chemistry that makes possible stable dosages - Quality content written by experienced experts from the drug development industry - Valuable information for academic and industrial scientists developing topical and liquid dosage formulations for pharmaceutical as well as skin care and cosmetic products
