TL;DR: In this article, the authors provide a comprehensive coverage of the discipline of atmospheric chemistry, starting with the fundamentals of kinetics and photochemistry, and show how the experimental techniques in these areas are applied to the study and control of chemical reactions in the troposphere.
Abstract: This book provides coverage of the discipline of atmospheric chemistry. Starting with the fundamentals of kinetics and photochemistry, it shows how the experimental techniques in these areas are applied to the study and control of chemical reactions in the troposphere. It gives detailed analysis of such major societal issues as smog, acid rain and volatile toxic organics. It also treats the seven criteria pollutants considered by the U.S. Environmental Protection Agency to be hazardous, as well as a variety of trace noncriteria pollutants, such as those cited in the Clean Air Act of 1977.

TL;DR: Most North American studies have shown that areas where low-socioeconomic-status communities dwell experience higher concentrations of criteria air pollutants, while European research has been mixed, but research in these parts of the world is limited.
Abstract: The existing reviews and meta-analyses addressing unequal exposure of environmental hazards on certain populations have focused on several environmental pollutants or on the siting of hazardous facilities. This review updates and contributes to the environmental inequality literature by focusing on ambient criteria air pollutants (including NOx), by evaluating studies related to inequality by socioeconomic status (as opposed to race/ethnicity) and by providing a more global perspective. Overall, most North American studies have shown that areas where low-socioeconomic-status (SES) communities dwell experience higher concentrations of criteria air pollutants, while European research has been mixed. Research from Asia, Africa, and other parts of the world has shown a general trend similar to that of North America, but research in these parts of the world is limited.

TL;DR: In this paper, the Clean Air Quality Standards (NAAQS) is defined in terms of six criteria pollutants, namely, particulate matter, sulfur oxides, carbon monoxide, nitrogen dioxide, lead, and photochemical oxidants (ozone).
Abstract: As part of the Clean Air Act, the federal government has established National Ambient Air Quality Standards (NAAQS) which attempt to define the desired, or permissible, maximum levels of pollutants in the air throughout the country The pollutants which are used to define the quality of air are termed the criteria pollutants, namely, particulate matter, sulfur oxides, carbon monoxide, nitrogen dioxide, lead, and photochemical oxidants (ozone), as listed in Table 3-1 Additional pollutants are regulated under the Clean Air Act; however, clean air is defined in terms of only these six criteria pollutants The NAAQS for criteria pollutants is listed in Table 3-2 along with the standard for nonmethane hydrocarbons

TL;DR: In this article, the authors present results of a comprehensive life-cycle energy, greenhouse gas emissions, and selected criteria air pollutant emissions inventory for automobiles, buses, trains, and airplanes in the US.
Abstract: To appropriately mitigate environmental impacts from transportation, it is necessary for decision makers to consider the life-cycle energy use and emissions. Most current decision-making relies on analysis at the tailpipe, ignoring vehicle production, infrastructure provision, and fuel production required for support. We present results of a comprehensive life-cycle energy, greenhouse gas emissions, and selected criteria air pollutant emissions inventory for automobiles, buses, trains, and airplanes in the US, including vehicles, infrastructure, fuel production, and supply chains. We find that total life-cycle energy inputs and greenhouse gas emissions contribute an additional 63% for onroad, 155% for rail, and 31% for air systems over vehicle tailpipe operation. Inventorying criteria air pollutants shows that vehicle non-operational components often dominate total emissions. Life-cycle criteria air pollutant emissions are between 1.1 and 800 times larger than vehicle operation. Ranges in passenger occupancy can easily change the relative performance of modes.
