Acidic precipitation: Considerations for an air quality standard

Comparison of Performances for Air-Standard Atkinson and Dual Combustion Cycles with Heat Transfer Considerations

There are heat losses during the cycle of real engine that are neglected in ideal air-standard analysis. In this paper, the effect of heat transfer on the net output work is shown and thermal efficiency of the air-standard Atkinson and the Dual combustion cycles are analyzed. Comparison of performances of the air-standard Atkinson and the Dual combustion cycles with heat transfer considerations...

Recommendation for an Ambient Air Quality Standard for Ozone

An Appropriate Theoretical Model for Developing Ambient Air Quality Standard in Iran Based on Standard Setting Approaches of Different Parts of the World

Background & objectives: Environmental standards are quantitative criteria for protecting the environment from pollution and degradation. One of the solutions to improve air quality status is to use reasonable limits to prevent excessive release of airborne contaminants from their various sources. On the other hand, these standards are effective in evaluating air pollution reduction strategies....

Special Considerations in Air Travel for Pregnant Women

Fire and Pesticides: Air Quality Considerations

The classes of primary chemical products naturally produced by the combustion of forest fuels include: carbon dioxide, water, carbon monoxide, particulate matter, methane and nonmethane hydrocarbons, polynuclear aromatic hyrocarbons, nitrogen and sulfur oxides, aldehydes, free radicals, and inorganic elements. Pesticides are a class of secondary chemical byproducts of fires that have been of so...
