Air quality economics: Three essays
… technique to investigate problems related to air quality economics. The first chapter is a general introduction to all three studies. The second chapter explores adopting an environmentally-friendly public transportation system in Europe. The Bayesian econometric methods show that willingness …

Petroleum refining and air quality management
Management of the air quality surrounding Petroleum Refineries deserves attention because the industry contributes almost five percent of the total emissions from all anthropogenic sources. A document containing a complete set of guidelines for use in the refining industry which satisfies the …

LearnAir : toward intelligent, personal air quality monitoring
Air pollution is responsible for :1/8 of deaths around the world. While the importance of air quality has led to a boom in inexpensive air sensors, studies have shown that the status quo of sparse, fixed sensors cannot accurately capture personal exposure levels of nearby populations. Especially in …

The architectural design process and indoor air quality
… as if it is occupied by users. Although, indoor air quality (IAQ) has been discussed for almost thirty years, it is a new subject for architects from the architectural design point of view. Most of the time, the subject is defined as an engineering problem. However anything related to the …

Evolving air quality and impact of changing climate
… on understanding the complex interaction of air quality and climate change using a suit of global climate chemistry model simulation using Community Earth System Model (CESM). The first phase of the research uses the global model simulation to investigate long-range transport of pollutants …

Measuring ambient air quality using low-cost sensors
Exposure to ambient air pollution increases morbidity and mortality - it is the leading environmental risk factor for the global burden of disease. Accurate and reliable air quality measurements can help identify sources of pollution, enabling mitigation strategies that lead to longer, healthier …

Decision support tools for urban air quality management
… gap between available data and action for urban air quality management, focusing on strategies to reduce particle concentrations. One of the principal thesis contributions is a Bayesian method to exploit the asymmetry between the rich aerosol dataset and the relatively poor dataset on gas-phase …

Incident-response monitoring technologies for aircraft-cabin air quality
Poor air quality in commercial aircraft cabins can be caused by volatile organophosphorus (OP) compounds emitted from the jet engine bleed air system during smoke/fume incidents. Tri-cresyl phosphate (TCP), a common anti-wear additive in turbine engine oils, is an important component in today’s …

Determination of indoor air quality at the Unlv campus
Research on air pollution has gained particular momentum over the past decade. The presence of volatile hydrocarbons, and aldehydes in indoor environments has raised concern about the safety and well-being of personnel exposed to environments containing these pollutants. Because of potential …

Predicting Air Quality Near Roadway Intersections Through The Applicat
… become imperative that the models used to assess air quality be as accurate as possible. The United States (US) Environmental Protection Agency (EPA) currently promulgates the use of CAL3QHC to model concentrations of carbon monoxide (CO) near roadway intersections. This model uses steady-state …

A Methodology for Improved, Data-Oriented, Air Quality Forecasting
Air quality has emerged as an acute environmental problem, especially in densely populated areas, causing amongst other things negative effects on health. Air quality forecasting system can potentially facilitate amelioration of the situation by providing alerts regarding potential high air …

Connecting Water Quality With Air Quality Through Microbial Aerosols
… materials (including nutrients and bacteria) to air. These materials can then be transported by onshore winds to land, representing a biogeochemical connection between aquatic and terrestrial systems not normally considered. In urban waterfront environments, this transfer could result in …

Study of building material emissions and indoor air quality
… considers VOC mass transfer processes in the air, material-air interface, material film, and the substrate. The model can predict "wet" material emissions under different environmental conditions (i.e., temperature, velocity, turbulence, and VOC concentration in the air) with reasonable …

Future trends in local air quality impacts of aviation
… estimate the health impacts of aviation-related air pollution. The model follows an impact pathway approach based on a review of the best practices for air quality policy-making in Europe and the United States. This model is used to develop the Air Quality Module within the Benefits Valuation …

Stabilized Explicit Time Integration for Parallel Air Quality Models
Air Quality Models are defined for prediction and simulation of air pollutant concentrations over a certain period of time. The predictions can be used in setting limits for the emission levels of industrial facilities. The input data for the air quality models are very large and encompass various …
