Treatment of dynamical processes in two-dimensional models of the troposphere and stratosphere

Description: The physical structure of the troposphere and stratosphere is the result of an intricate interplay among a large number of radiative, chemical, and dynamical processes. Because it is not possible to model the global environment in the laboratory, theoretical models must be relied on, subject to observational verification, to simulate atmospheric processes. Of particular concern in recent years has been the modeling of those processes affecting the structure of ozone and other trace species in t… more

Calculation of particulate dispersion in a design-basis tornadic storm from the Atomics International Nuclear Material Development Facility, Santa Susana, California

Description: A three-dimensional numerical model is used to calculate ground-level air concentration and deposition (due to precipitation scavenging) after a hypothetical tornado strike at the Atomics International Nuclear Material Development Facility at Santa Susana, California. Plutonium particles less than 20 ..mu..m in diameter are assumed to be lifted into the tornadic storm cell by the vortex. The rotational characteristics of the tornadic storm are embedded within the larger mesoscale flow of the st… more

Sampling and analysis of trace-organic constituents in ambient and workplace air at coal-conversion facilities

Description: A review of the recent literature reveals that current sampling procedures involve the use of glass fiber filters for particulate-sorbed organics and sorbent resins such as Tenax GC and XAD-2 for vapor-phase organics. Ultra trace-organic analysis of air pollutants or particulates may require the collection of a large (1000 to 3000 m/sup 3/) sample by a high volume air sampler. Personal air sampling requires a smaller (approx. = 0.5 m/sup 3/) and a portable collection apparatus. Trapped organic … more

Po-210 as long-term integrating radon indicator in the indoor environment

Description: The general objective is to improve the knowledge about the transferring processes leading from airborne radon/radon daughters to embedded Po-210 in hard surfaces in the indoor environment. The specific goal of the research is to identify situations in which the surface activity of Po-210 can be used as a long-term indicator of lung cancer risk from past or future radon exposures.

Enhancing the use of coals by gas reburning-sorbent injection

Description: The objective of this project is to evaluate and demonstrate a cost effective emission control technology for acid rain precursors, oxides of nitrogen (NO{sub x}) and sulfur (SO{sub x}), on two coal fired utility boilers in Illinois. The units selected are representative of pre-NSPS design practices: tangential and cyclone fired. Work on a third unit, wall fired, is on hold'' because of funding limitations. The specific objectives are to demonstrate reductions of 60 percent in NO{sub x} and 50 … more

Transport of radon and thoron at the earth's surface

Description: This report covers progress under the current funding period 1 Jan 1992 to 1 Jan 1993 and presents the continuation proposal for 1 Jan 1993 to 1 Jan 1994. The previous progress report was submitted in June 1991, so activities during the last half of 1991 will also be included. Our major activities over the last year have continued to focus on measurements and modeling of the disequilibrium of radon and thoron progeny outdoors, and analysis of data on indoor thoron and thoron progeny.

Radionuclide distributions and migration mechanisms at shallow land burial sites. Annual report of research investigations on the distribution, migration and containment of radionuclides at Maxey Flats, Kentucky. [Maxey Flats]

Description: Subsurface waters at Maxey Flats are anoxic systems with high alkalinity and high concentrations of dissolved ferrous ion. Americium and cobalt in these trench waters are made more soluble by the presence of EDTA, while strontium and cesium are unaffected under the same conditions. EDTA is the major organic complexing component in waste trench 27 leachate, but other polar, water-soluble organics are also present. Evidence points to the migration of plutonium between waste trench 27 and inert at… more

Transport of solid commodities via freight pipeline: impact assessment. Volume V. First year final report

Description: The application of freight pipeline for the movement of solid goods offers a new option in the field of transportation. This volume examines impacts and their assessments. This study has only identified the areas where truck and/or rail substitution by pipeline may have impacts. It only can be said that pipeline, if it can substitute for surface traffic without correspondingly increasing it at another location, is inherently a more environmentally compatible mode of transport. Based on data pre… more

Assessment of geothermal development in the Imperial Valley of California. Volume 2. Environmental control technology

Description: Environmental control technologies are essential elements to be included in the overall design of Imperial Valley geothermal power systems. Environmental controls applicable to abatement of hydrogen sulfide emissions, cooling tower drift, noise, liquid and solid wastes, and induced subsidence and seismicity are assessed here. For optimum abatement of H{sub 2}S under a variety of plant operating conditions, removal of H{sub 2}S upstream of the steam turbine is recommended. The environmental impa… more

CO sub 2 emissions from developing countries: Better understanding the role of energy in the long term

Description: Recent years have witnessed a growing recognition of the link between emissions of carbon dioxide (CO{sub 2}) and changes in the global climate. Of all anthropogenic activities, energy production and use generate the single largest portion of these greenhouse gases. Although developing countries currently account for a small share of global carbon emissions, their contribution is increasing rapidly. Due to the rapid expansion of energy demand in these nations, the developing world's share in gl… more

Estimation of spatial distributions from point sources with application to air pollution measurement. Technical report No. 9

Description: A class of weighted estimators of a stationary distribution function is introduced which exploits correlation structure in the data as frequently found in air quality measurements. The nature of these weighted estimates is examined for several simple cases, in particular for spatially clustered measurements where the advantage over the usual empirical distribution function seems most pronounced. An illustration is presented using total suspended particulate concentrations from a 14-station moni… more
