School Air Toxic Monitoring Project: Church Rock Elementary School

January 2015 (has links)
abstract: United States Environmental Protection Agency (USEPA) had identified and recommended air quality monitoring to take place at 63 schools throughout the country. Unfortunately, tribal schools were not considered during the time USEPA conducted the analysis. The importance of identifying any air toxic pollutants affecting school children needs to be analyzed. Conducting an air monitoring toxic analysis on the Navajo Nation at Church Rock Elementary School, Church Rock, New Mexico (CRNM) was carried out. The current school location posed a concern, in regards to the surrounding stationary, mobile, and natural emissions emitted all types of toxic pollutants. USEPA sponsors various air monitoring program, which Tribal Air Monitoring Support (TAMS) program undertook, and offered tribal programs, organizations or agencies to utilized air monitoring equipment's. The air monitoring setup was conducted with the contract Eastern Research Group, Inc. (ERG) laboratory, where collection of 24-hour ambient air samples for 60 days on a 6-day sampling interval were performed. The analysis for volatile organic compounds (VOCs)were collected from canister samples using USEPA Compendium Method TO-15, polycyclic aromatic hydrocarbons (PAHs) from polyurethane foam (PUF) and XAD-2 resin samples using USEPA Compendium Method TO-13A. Carbonyl compounds were collected by sorbent cartridge samples using USEPA Compendium Method TO-11A, and trace of metals from filters were sampled using USEPA Compendium Method IO-3.5 and FEM EQL-0512-202. A total of 53 VOC concentrations were greater than 1 μg/m3, where dichlorodifluoromethane, trichlorofluoromethane, chloromethane, dichloromethane, propylene, toluene, acrolein and acetylene were detected. A total of 23 carbonyl compound concentrations were greater than 1 μg/m3, where acetone and formaldehyde were measured. Naphthalene average with the highest average for PAHs, where phenanthrene and retene were the second and third highest averages. As for the metals the highest averages resulted from manganese, chromium and lead. Overall, the air toxic pollutants resulted from CRNM surrounding monitoring site were detected. Identifying the potential emitter source or sources cannot be assessed. / Dissertation/Thesis / Masters Thesis Engineering 2015

The Failed Bombing Offensive: A Reexamination Of The Combined Bomber Offensive In 1943

Truxal, Luke W. 12 1900 (has links)
For decades nations have debated how to successfully employ air power. In 1943 the United States and Great Britain launched a massive strategic bombing campaign against Germany. The two sides agreed to a flawed plan due to the fundamental differences on bombing doctrine. As a result, the campaign was fraught with issues that remained largely unresolved in 1943. Without a clearly defined plan, the Allies were unable to determine which commands or targets received priority throughout the offensive. This ultimately led to a confused and unfocused campaign. High losses and inconclusive results derailed the American bombing effort. By November, the two sides agreed that the entire bombing offensive was either behind schedule or had failed entirely.

Composition, time, and size distributions of airborne particulate material in Utah Valley

Lawson, Douglas R. 01 April 1975 (has links)
The Lundgren impactor is used to determine the variations in time and size distributions of particulate matter in Utah Valley. Charged particle X-ray fluorescence is employed in this study to determine elemental concentrations. Air samples are taken during two 24-hour periods in downtown Provo, 24 hours near U.S. Steel Corporation, Geneva Works, and 12 hours at Lindon Elementary School, and diurnal particulate variations are compared. The amounts of lead and bromine are four times greater on a weekday than on a Sunday in downtown Provo, suggesting the effect of the automobile on atmospheric particulate concentrations. Paraffin coated impaction surfaces are compared with uncoated surfaces, and it is shown that collection efficiency is at least 1.5 times greater when a coated impaction surface is used. The effect of rainfall on particulate levels is studied. Experimental results show that potassium, calcium, iron, and titanium are concentrated in larger airborne particulates, while lead, bromine, zinc, and manganese are concentrated in the smaller particles.
