Book Description
"The original purpose of this research was to investigate the possibility of building an electrostatic particle size discriminator. We went beyond this objective and have worked out theoretically and experimentally a new method for determination of particle size distribution by settling charged aerosol particles in an electrostatic field. Two further methods based on gravitational and centrifugal settling of charged aerosol particles were developed theoretically"--p.1, 1954/1955.

Book Description
AEROSOL TECHNOLOGY An in-depth and accessible treatment of aerosol theory and its applications The Third Edition of Aerosol Technology: Properties, Behavior, and Measurement of Airborne Particles delivers a thorough and authoritative exploration of modern aerosol theory and its applications. The book offers readers a working knowledge of the topic that reflects the numerous advances that have been made across a broad spectrum of aerosol-related application areas. New updates to the popular text include treatments of nanoparticles, the health effects of atmospheric aerosols, remote sensing, bioaerosols, and low-cost sensors. Additionally, readers will benefit from insightful new discussions of modern instruments. The authors maintain a strong focus on the fundamentals of the discipline, while providing a robust overview of real-world applications of aerosol theory. New exercise problems and examples populate the book, which also includes: Thorough introductions to aerosol technology, key definitions, particle size, shape, density, and concentration, as well as the properties of gases Comprehensive explorations of uniform particle motion, particle size statistics, and straight-line acceleration and curvilinear particle motion Practical discussions of particle adhesion, Brownian motion and diffusion, thermal and radiometric forces, and filtration In-depth examinations of sampling and measurement of concentration, respiratory deposition, coagulation, condensation, evaporation, and atmospheric aerosols Perfect for senior undergraduate and junior graduate students of science and technology, Aerosol Technology: Properties, Behavior, and Measurement of Airborne Particles will also earn a place in the libraries of professionals working in industrial hygiene, air pollution control, climate science, radiation protection, and environmental science.

Book Description
The selection and design of aerosol removal equipment depend largely on knowledge of the size of the particle. In this work the distribution of particle sizes of aerosols of sulfuric, phosphoric, hydrochloric, hydrobromic, chlorosulfonic, and nitric acids was measured by means of a four-stage, high velocity jet impactor. The effect of the relative humidity of the air system, the addition of foreign nuclei, the concentration of the aerosol particles and time on the size distribution was studied.

Book Description
The National Institute of Allergy and Infectious Diseases (NIAID) gives the highest priority to developing countermeasures against bioterrorism agents that are highly infective when dispersed in aerosol form. Developing drugs to prevent or treat illnesses caused by bioterrorism agents requires testing their effectiveness in animals since human clinical trials would be unethical. At the request of NIAID, the National Academies conducted a study to examine how such testing could be improved. Overcoming Challenges to Develop Countermeasures Against Aerosolized Bioterrorism Agents provides recommendations to researchers on selecting the kinds of animal models, aerosol generators, and bioterrorism agent doses that would produce conditions that most closely mimic the disease process in humans. It also urges researchers to fully document experimental parameters in the literature so that studies can be reproduced and compared. The book recommends that all unclassified data on bioterrorism agent studies-including unclassified, unpublished data from U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID)-be published in the open literature. The book also calls on the U.S. Food and Drug Administration to improve the process by which bioterrorism countermeasures are approved based on the results of animal studies.

Book Description
Fine Particles: Aerosol Generation, Measurement, Sampling, and Analysis is a collection of technical papers presented at the Symposium on Fine Particles held in Minneapolis, Minnesota, on May 28-30, 1975. The symposium aims to explore the developments in instrumentation and experimental techniques for aerosol studies. This book is organized into four parts encompassing 34 chapters that focus on fine particles below about 3.5 μm in diameter. Part I presents the research and development in Europe and Japan on fine particles and aerosols, as well as the aerosol standards development work at the Particle Technology Laboratory, University of Minnesota. This part also includes calibration studies on condensation nuclei counters and the diffusion battery. Significant chapters in Part II are devoted to the common techniques for generation of aerosols of various sizes, from fine particles to monodisperse aerosols. This part further looks into the equipment limitations and problems in producing fine particle aerosols for life testing air cleaning systems and for weather modification experimentation. Part III describes the techniques and equipment used for size-selective aerosol sampling in terms of the design principles applied, the correspondence between design and performance of specific samplers, their applicability to field conditions, and their ability to satisfy sampler acceptance criteria. Part IV deals first with the methods for determination of aerosol properties, including their optical, electrical, and spectral properties. Other chapters examine the principles, mode of operation, and application of processes and instruments for aerosol studies.

Book Description
Biological warfare agent (BWA) detectors are designed to provide alerts to military personnel of the presence of dangerous biological agents. Detecting such agents promptly makes it possible to minimize contamination and personnel exposure and initiate early treatment. It is also important, though, that detectors not raise an alarm when the situation does not warrant it. The question considered in this book is whether Agent-Containing Particles per Liter of Air (ACPLA) is an appropriate unit of measure for use in the evaluation of aerosol detectors and whether a better, alternative measure can be developed. The book finds that ACPLA alone cannot determine whether a health threat exists. In order to be useful and comparable across all biological agents and detection systems, measurements must ultimately be related to health hazard. A Framework for Assessing the Health Hazard Posed by Bioaerosols outlines the possibility of a more complex, but more useful measurement framework that makes it possible to evaluate relative hazard by including agent identity and activity, particle size, and infectious dose.
