Emission quantification associated with firewood usage: A case study of Mangondi village in Limpopo Province, South Africa
… is not fully combusted. A large quantity of criteria pollutants and greenhouse gas (GHG) are released to the atmosphere from such combustion which potentially contributes to global warming and climate change. The aim of this study was to quantify the emissions resulting from the use of …

Emission quantification associated with firewood usage: A case study of Mangondi village in Limpopo Province, South Africa.
… is not fully combusted. A large quantity of criteria pollutants and greenhouse gas (GHG) are present in the atmosphere causing global warming and climate change due to domestic wood combustion (DWC). The aim of this study is to quantify the use of firewood as a source of energy in Mangondi …

Technology and policy options for reducing industrial air pollutants in the Mexico City Metropolitan Area
… (MCMA). Environmental standards for most of the criteria pollutants have frequently been violated in the MCMA. Severe air pollution in the MCMA, and the roles of point and area sources, particularly industrial sector, are the prime motivating factors for this research. Industrial sources of air …

Particulate Matter Air Monitoring Network in the San Francisco Bay Area: Assessment and Management Recommendations
<p>Particulate matter is one of six criteria pollutants regulated by the U.S. EPA. The purpose of this paper is to evaluate the current particulate matter (PM<sub>10</sub> and PM<sub>2.5</sub>) air monitoring network operated by the Bay Area Air Quality Management District (BAAQMD), or Air …

Economics of air pollution: policy, mortality concentration-response, and increasing marginal benefits of abatement
… model to estimate the marginal damage caused by criteria pollutants in the United States. In the first essay, the optimal abatement policy is derived for a scenario with increasing marginal benefits of abatement and uncertainty in the marginal cost of abatement. Pollution taxes are preferred over …

Economically and ecologically sustainable adoption of stationary fuel cells in the USA
… such as carbon dioxide, sulfur oxide and other criteria pollutants. These chemicals are proven to adversely affect human health and are suspected of influencing the global climate. Consequently, there is a high potential for damages in some parts of earth but also benefits in others, …

Plantwide Control System Design for IGCC Power Plants with CO2 Capture
… such as emission penalties for CO2 or other criteria pollutants can be considered in the control system design.;The control system design is performed in two stages. In the first stage, a top-down analysis is used to generate a list of controlled, manipulated, and disturbance variables …

Capturing the impacts of land use on travel behavior : comparison of modeling approaches
… as measured through emitted grams of five criteria pollutants (C0 2, VOCs, PM10, CO and NO,). To answer this question, two different modeling techniques are employed to investigate the variables related to car ownership and travel behavior. The first analysis uses a discrete-continuous …

Unraveling atmospheric physics and chemistry of long-range transport of pollutants: Development of novel tools and methods
Long-range transport (LRT) of pollutants causes changes in background concentrations of pollutants (e.g., ozone, O3; and nitrogen dioxide, NO2) and alarming high peaks of unhealthy criteria pollutants (e.g., particulate matter, PM; and carbon monoxide, CO) in downwind regions. As the chemical …

Ambient air pollution monitoring, modelling and human health risks in Thulamela Municipality, Vhembe District of Limpopo Province, South Africa
… is a pressing global environmental concern, with pollutants from natural and anthropogenic sources contributing to deteriorating air quality. This research investigates the impact of sulfur dioxide (SO₂), nitrogen oxides (NOₓ), carbon monoxide (CO), and particulate matter (PM2.5 and PM10) on human …
