Book Description
Coal remains one of the principal sources of energy for the United States, and the nation has been a world leader in coal production for more than 100 years. According to U.S. Energy Information Administration projections to 2050, coal is expected to be an important energy resource for the United States. Additionally, metallurgical coal used in steel production remains an important national commodity. However, coal production, like all other conventional mining activities, creates dust in the workplace. Respirable coal mine dust (RCMD) comprises the size fraction of airborne particles in underground mines that can be inhaled by miners and deposited in the distal airways and gas-exchange region of the lung. Occupational exposure to RCMD has long been associated with lung diseases common to the coal mining industry, including coal workers' pneumoconiosis, also known as "black lung disease." Monitoring and Sampling Approaches to Assess Underground Coal Mine Dust Exposures compares the monitoring technologies and sampling protocols currently used or required by the United States, and in similarly industrialized countries for the control of RCMD exposure in underground coal mines. This report assesses the effects of rock dust mixtures and their application on RCMD measurements, and the efficacy of current monitoring technologies and sampling approaches. It also offers science-based conclusions regarding optimal monitoring and sampling strategies to aid mine operators' decision making related to reducing RCMD exposure to miners in underground coal mines.

Book Description
Forensic, Occupational and Environmental Health Sciences are identification sciences dealing with criminal and delicate societal problems for which scanning electron microscopy (SEM) with energy dispersive x-rays (EDAX) and analytical transmission electron microscopy (TEM) are providing increasingly definitive solutions. This is particularly true in the area of particulates. However, electron microscopists working independently in these three related fields are often called upon to identify particulates which have been well characterized by microscopists in one of the other fields of study. Exchange of information on particulate identification and techniques for analyzing new unusual samples has been difficult between the three disciplines. For example, automated search and identification of particulates has become a standard procedure in environmental and occupational health. The procedure, however, has yet to find its way into forensic laboratories for analysis of gunshot residue particles. This volume represents a beginning for collaboration and exchange of ideas between such areas of study with diverse interests but similar analytical problems. It is virtually certain that this effort will also interest other electron microscopists in some novel scientific problems with criminal and societal relevance. The volume presents full-length articles of several invited speakers and participants at the "Forensic, Occupational and Environmental Health Sciences" Symposium held as a part of the EMSA-MAS Joint Annual Meeting, 5-9 August 1985, Louisville, Kentucky. Extended 2-4 page abstracts of these presentations have been published in the EMSA Proceedings (1985).
