The Bureau of Mines laboratory tested the response of a commercially available real-time aerosol monitor (GCA RAM-I) to various dusts. Monitor measurements were recorded, averaged, and compared with simultaneous gravimetric measurements of each test dust. Tests usually lasted several hours. The test dusts of various particle size distributions used included coal, limestone, and a commercially available test dust. For each particular dust, the monitor response was linear and correlated well with mass concentration over the range of about 0.5 to 10 mg/ma3 The monitor can estimate a 2.0-mg/m3 respirable coal dust concentration within as little as ± 6 pet with 95 pet confidence. The monitor must, however, be calibrated with the dust to be measured because the instrument response is affected by the type of dust particle. The average monitor response to a mass concentration of coal dust was approximately twice the average monitor response to the same mass concentration of limestone dust.

Download Aerosol Technology In Hazard Evaluation Book in PDF, ePub and Kindle
Aerosol Technology in Hazard Evaluation is the fifth in the series of books on the subject of aerosol technology. This series is organized into nine chapters that cover the properties, sampling, and respirable activity of aerosol. After briefly describing the nature of an inhalation hazard, the book examines the properties, measurement, and significance of geometric diameters of aerosols, as well as the shape factors relating them to various particulate properties. The mathematical description of size distributions and the statistics of sampling from a lognormal distribution of particle sizes are provided. Considerable chapters deal with the methods of aerosol concentration measurement and geometric and aerodynamic size sampling. Operating characteristics of respirable aerosol activity samplers and their limitations are also examined. The concluding chapter discusses problems in the production, flow measurement, apparatus calibration, and isokinetic sampling of aerosols. This series will provide a convenient source of information to those concerned in industrial hygiene and will stimulate the interest of those involved in all phases of environmental health.

Download Comparison of Real-time Smoke Particulate Monitors with a Federal Reference Method Sampler Book in PDF, ePub and Kindle
This paper presents findings on the accuracy of real-time smoke particulate monitors when compared with the U.S. Environmental Protection Agency Federal Reference Method (FRM) gravimetric sampler. The U.S. Department of Agriculture, Forest Service, National Technology and Development Program (T&D), performed the last evaluation on real-time smoke particulate monitors during 2006. Since that time, the manufacturers have refined and upgraded many of the real-time smoke monitors T&D evaluated. The Forest Service Air Resource Management Program asked T&D to performa market search for new, portable, real-time smoke particulate monitors and provide an update on their accuracy when compared with an FRM gravimetric sampler. This paper provides information on the accuracy of Met One Instruments Inc., E-Samplers and E-BAMs and a TSI Inc., DustTrak DRX Aerosol Monitor 8533 when compared with an FRM sampler.

Download Aerosol Sampling and Characterization for Hazard Evaluation. Progress Report, October 1, 1977-September 30, 1978. [239Pu Aerosol Monitor Performance in Work Area]. Book in PDF, ePub and Kindle
Measurements of the dilution of air contaminants between worker breathing zone and area air samplers were made by releasing a test fluorescent aerosol in workrooms equipped with aerosol surveillance systems. These data were used to evaluate performance and suggest improvements in design of alarming air monitor systems. In one workroom studied, average half-hour breathing zone air concentration needed to trigger alarm was found to be 960 times the maximum permissible air concentration for occupational exposure to soluble 239Pu (MPC/sub a/). It was shown that alternative monitor placement in this room could result in decreasing average triggering concentration to 354 times the MPC/sub a/. Analysis of data from impaction-autoradiographic sizing comparison studies showed average disintegration to track ratio called track efficiency factor, to be 2.7 +- 0.4.

Download Aerosol Measurement Book in PDF, ePub and Kindle
In recent years, industry has become increasingly interested in modern aerosol measurement methods, not only to protect the health of their workers but also to augment productivity and thereby gain competitive advantage. Aerosol Measurement: Principles, Techniques, and Applications, Second Edition offers scientists and practitioners the fundamental principles used in deciding which aerosol properties to measure and how to interpret the results. Divided into three parts, the material reviews the physical understanding of aerosols, covers specific instrumental techniques, and explains applications in fields ranging from health care to mining and upper-atmosphere research. Leading experts contribute to the review of such areas as direct-reading techniques, bioaerosol sampling, indoor air evaluations, industrial aerosol processing, and measurement in semiconductor clean rooms. Plus, all the chapters in this latest edition have been updated and some have been rewritten by new authors. Two new chapters have been added: one on historical aspects of aerosol measurements and the other on real-time single particle analysis.
