Air Quality Modelling For Ireland, Aoife Donnelly, Bruce Misstear, Brian Broderick

Reports

Air pollution is the primary environmental cause of premature death in the EU (European Commission, 2013) and the most problematic pollutants across Europe have consistently been oxides of nitrogen (e.g. nitrogen dioxide (NO₂)), particulate matter (e.g. PM₁₀, PM_2.5) and ozone (O₃). While measurements form an important aspect of air quality assessment, on their own they are unlikely to be sufficient to provide an accurate spatial and temporal description of the pollutant concentrations for exposure assessment and moreover they cannot provide information regarding future air quality. Annex XVI of 2008/50/EC requires member states …

Health Benefits From Upgrading Public Buses For Cleaner Air: A Case Study Of Clark County, Nevada And The United States, John O. Olawepo, L.-W. Antony Chen

Public Health Faculty Publications

Public transit buses, which move more than 5 billion passengers annually in the United States (U.S.), can contribute substantially to the environmental health burden through emitted air pollutants. As a leader in transforming to cleaner bus fleets, the Regional Transport Commission of Southern Nevada (RTC) has been transitioning from diesel to compressed natural gas (CNG) transit buses since 1999. By 2017, ~75% of RTC’s buses operating in Clark County, Nevada were CNG-powered. This study assesses the health benefits of the venture using the US Environmental Protection Agency’s (EPA) Co-Benefits Risk Assessment (COBRA) model, considering the emission and exposure changes from …

The Effect Of Particles Pm10 And Pm2.5 In Dust Emission Of Urban Infrastructure From Thermal Power Plant Technology Kosovo, Afrim Syla

International Journal of Business and Technology

Airborne particulate matter with aerodynamic diameters less than 10 microns (referred to as PM10) is one of the six criteria pollutants used by the U.S. Environmental Protection Agency as indicator of air quality. During the last decade, the health effects of urban aerosols have become a major concern for the society.

The main environmental problems in Kosovo include all issues related to water supply and sanitation system, air quality, solid waste management and urban infrastructure. The major problem remains high pollutions, energy losses and low collection efficiency. The awareness of environmental issues among the general public is poor. Air quality …

Caracterización De Bioaerosoles Presentes En Las Áreas Cercanas A Las Estaciones De La Red De Monitoreo De La Calidad Del Aire De La Zona Industrial De Bogotá, Angie Lorena Díaz Molina, Lina Fernanda Hernández Coca

Ingeniería Ambiental y Sanitaria

La contaminación atmosférica como problema ambiental, social y de salud pública es ampliamente conocida y relacionada con fuentes de tipo industrial, móviles o puntuales. Su control y monitoreo se reduce a la obtención de valores de concentraciones emitidas de los contaminantes criterio (SO2, NOx, PM10 y PM2.5). No obstante, también existe la contaminación de tipo biológico: Los bioaerosoles (partículas sólidas o líquidas, que corresponden a partículas de origen natural vivo como granos de polen, esporas, bacterias, hongos, entre otros) presentes en la atmósfera se encuentran relacionados a producción y transmisión de virus y enfermedades infecciosas respiratorias. Sin embargo, la información …

Assessing Spatiotemporal Exposures To Transportation Pollutants In Near-Road Communities Using Aermod, Mayra Consuelo Chavez

Open Access Theses & Dissertations

Traffic-related air pollution has a profound impact on human health especially for residents living in near-road communities which are constantly exposed these air pollutants. A near-road community is expected to observe significant spatial and temporal variations in pollutant concentrations, as air pollution resulting from emissions from major highways decreases rapidly from the highway. This research conducted on-site traffic and air quality measurements on four critical transportations related air pollutants, PM2.5, PM10, NO2, O3, as well as emission and air dispersion modeling of transportation emission impacts in a near-road community. Using numerical models provided by the EPA, integrated with field measurements …
