This book is the eighth volume in the series Acute Exposure Guideline Levels for Selected Airborne Chemicals, and reviews AEGLs for acrolein, carbon monoxide, 1,2-dichloroethene, ethylenimine, fluorine, hydrazine, peracetic acid, propylenimine, and sulfur dioxide for scientific accuracy, completeness, and consistency with the NRC guideline reports.

Occupational exposure to heat can result in injuries, disease, reduced productivity, and death. To address this hazard, the National Institute for Occupational Safety and Health (NIOSH) has evaluated the scientific data on heat stress and hot environments and has updated the Criteria for a Recommended Standard: Occupational Exposure to Hot Environments [NIOSH 1986a]. This updated guidance includes information about physiological changes that result from heat stress, and relevant studies such as those on caffeine use, evidence to redefine heat stroke, and more.

Acute Exposure Guideline Levels for Selected Airborne Chemicals, Volume 15 identifies, reviews, and interprets relevant toxicologic and other scientific data for ethyl mercaptan, methyl mercaptan, phenyl mercaptan, tert-octyl mercaptan, lewisite, methyl isothiocyanate, and selected monoisocyanates in order to develop acute exposure guideline levels (AEGLs) for these high-priority, acutely toxic chemicals. AEGLs represent threshold exposure limits (exposure levels below which adverse health effects are not likely to occur) for the general public and are applicable to emergency exposures ranging from 10 minutes (min) to 8 h. Three level--AEGL-1, AEGL-2, and AEGL-3--are developed for each of five exposure periods (10 min, 30 min, 1 h, 4 h, and 8 h) and are distinguished by varying degrees of severity of toxic effects. This report will inform planning, response, and prevention in the community, the workplace, transportation, the military, and the remediation of Superfund sites.

The aim of radiation protection standards is to make the radiation workplace as safe as is humanly possible. The gradual evolution over the last 20 years has been towards a more precise definition of the limits for occupational exposure. These have been created not only in terms of short-term effects but also more importantly in terms of long-term risks involving such problems as the potential for carcinogenesis and genetic change. In the United States the National Committee for Radiation Protection has recom mended that 5 rems (50 mSv) should remain as the maximum permissible dose equiva lent for total body exposure. This would represent the sum of internal and external ex posure and should be regarded as the upper limit allowed. The community of radiation users is required to conduct its operations in such a man ner that the absolute value of the individual's dose equivalent in rems does not exceed his age in years. There should be additional limits for tissues and organs based on short term effects. Therefore, individual organs are limited to dose equivalents low enough to ensure that the dose threshold values are not exceeded.

In response to rapidly accumulating evidence that environmental tobacco smoke (ETS) exposure causes disease beyond lung cancer & respiratory effects in children, the Calif. Environmental Protection Agency undertook a comprehensive assessment of the total range of health effects correlated with exposure to ETS. Chapters: impact of ETS on the health of Californians; exposure measurement & prevalence; developmental toxicity I: perinatal manifestations; developmental toxicity II: postnatal manifestations; reproductive effects; respiratory health effects; carcinogenic effects; & cardiovascular effects. Dozens of tables & figures.

Prenatal Cocaine Exposures addresses the timely problem of maternal cocaine abuse and its effects on exposed infants, including growth retardation, learning, cardiovascular effects, and seizures. The impact of substance abuse on this and future generations presents an ongoing challenge to medical science. This comprehensive and authoritative volume reviews both animal and clinical studies to explain implications for treatment and long-term outcomes of early exposure. Prenatal Cocaine Exposures investigates the specific role of cocaine in altering fetal development. Discussions of current studies and state-of-the-art techniques provide a basis for informed clinical decisions. Pediatricians, medical specialists, basic scientists, educators, and policy makers will all benefit from the comprehensive research gathered in this volume.
