Book Description
Scanning Electron Microscopy (SEM) coupled with Energy-Dispersive X-ray analysis (EDX) is a powerful tool in the characterization and source apportionment of environmental particulate matter (PM), providing size, chemistry, and morphology of particles as small as a few tenths of a micrometer. Such information can reveal information about emission sources which cannot be determined through bulk chemical analysis. Automated SEMs capable of routinely analyzing hundreds of particles per hour have dramatically increased the throughput of SEM/EDX, making it feasible to conduct statistically meaningful analyses of PM samples and to generate large data sets for source apportionment studies. The National Exposure Research Laboratory (NERL) of the U.S. EPA has been developing and evaluating the use of SEM/EDX to characterize ambient and source-derived particles. The present document, which evolved over several years as a product of research carried out in support of the U.S. EPA/NERL SEM/EDX Laboratory, is intended to provide guidelines for researchers using SEM/EDX for aerosol characterization and source apportionment. Topics include laboratory procedures for sample handling, sample preparation, guidelines for successful manual and automated SEM/EDX analyses, data interpretation, issues relating to data quality and method validation and case studies highlighting the use of SEM/EDX in PM research

Book Description
Measurement of ambient particulate matter (PM) mass and chemical composition is important for source attribution, studies of health and welfare effects, and determination of compliance with standards. A comprehensive approach to PM monitoring requires a combination of analytical techniques to assess mass and chemical composition, and an integrated network of ambient and stack/source PM monitors. There are several commercially available devices that can continuously monitor PM mass. However, none of these methods have been approved by the EPA, since most of these devices do not directly measure mass. In addition, chemical analysis of PM is costly and difficult, since existing technologies are not capable of continuous sampling/monitoring for chemical composition. Therefore, the next generation of PM monitors should be multi-functional instruments capable of continuous, real-time monitoring of both PM mass and chemical composition. In addition, they will need to address several barriers to their use including cost, complicated calibration and verification systems, and cumbersome installation and maintenance procedures.

Book Description
Particulate matter (PM)-dust, dirt, smoke, soot, and liquid droplets-comes from a variety of sources and is a mixture of many pollutants made up of several different chemical species. Recent evidence about health effects and the fundamental physical and chemical differences between fine and coarse PM prompted the EPA to set new standards. Monitoring to determine whether an area has met these standards requires a comprehensive approach that combines analytical techniques to assess mass and chemical composition with an integrated network of ambient and source PM monitors.

Book Description
Research has shown that inhaling fine particles is a greater health risk than breathing larger particles. Title is "very timely...needed NOW," according to one reviewer Covers a "controversial" but important topic, for which there is a lack of literature and hence guidance for those professionals affected by it Covers legislative background and gives insight into regulatory and technical matters such as measurement and control of fine particle emissions Combines the practical, theoretical, and regulatory areas of fine particulate monitoring, with "reference to the regulated community" Written by a recognized authority with over 30 years of pollution control experience
