Available in PDF, EPUB and Kindle. Book excerpt: 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 or read book Assessment of Exposure to Indoor Air Pollutants written by Matti Jantunen and published by WHO Regional Office Europe. This book was released on 1997 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most people spend most of their time indoors, and the poor quality of the indoor environment is a strong determinant of a variety of health problems. The principal way of preventing adverse health effects is to eliminate exposure to hazardous factors. But first, standardized methods of assessing exposure are necessary to assess the risk to health and to select optimal risk management actions. This book aims to facilitate the implementation of exposure assessment methods in public health practice.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research developed efficient applications of portable measurement systems to assess human exposure to traffic-related air pollution through direct measurement, and evaluation of exposure models.Passive NO2 samplers are deployed at large numbers of sites in epidemiological studies to estimate typical concentrations over 1-4 weeks. I found that deployment time could be reduced to 2 days with limited impact on the accuracy and precision of exposure estimates. This shorter measurement time enabled observation of wind-speed effects leading to overestimation of ambient concentrations by passive samplers. Through development of a post-processing technique and/or inclusion of a membrane I improved sampler accuracy. Portable sensors can provide detailed estimates of personal exposures to air pollution. Many sensor-based monitors have not been subject to rigorous testing procedures to quantify their accuracy. I observed that the most accurate estimates of concentrations from NO2 and O3 sensor-based monitors required regular, intermittent calibration against reference analysers under similar environmental conditions to field measurements. I also found deterioration in BC monitor accuracy and precison when the attenuation of the collection filter exceeded 40 and no improvement in monitor accuracy was observed when filter darkness correction algorithms were applied. Portable sensors can be used to identify locations with higher concentrations, which may require more detailed monitoring. I established that repeated 6-minute measurements of BC and particle number concentrations estimated similar spatial trends to 1-week NO2 measurements using passive samplers. Dispersion models can be used to estimate pollution exposure at multiple locations over a study area. I found that initial user parameterisation in a weather model had limited effect on pollution estimates from a dispersion model. I evaluated a new GIS-based dispersion model (5 x 5 m NO2 estimates for a 3,500 km2 area, with model run times of under 10 minutes). I demonstrated that inclusion of discrete street canyon models and geospatial surrogates (accounting for urban morphology) improved model accuracy. The measurement and modelling evaluation research in this thesis complimented each other by providing efficient ways to directly measure population exposures.

Download or read book Comparison of Real time Smoke Particulate Monitors with a Federal Reference Method Sampler written by Mary Ann Davies and published by . This book was released on 2015 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2000-04-21 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since Operation Desert Shield/Desert Storm, Gulf War veterans have expressed concerns about health effects that could be associated with their deployment and service during the war. Although similar concerns were raised after other military operations, the Gulf War deployment focused national attention on the potential, but uncertain, relationship between the presence of chemical and biological (CB) agents and other harmful agents in theater and health symptoms reported by military personnel. Strategies to Protect the Health of Deployed U.S. Forces which is one of the four two-year studies, examines the detection and tracking of exposures of deployed personnel to multiple harmful agents.
