Results from CHIE studies are used to inform the periodic review of National Ambient Air Quality Standards (NAAQS) for common pollutants, such as ozone and particulate matter (PM), and advise other policy decisions. The NAAQS process has broad health importance because it regulates the outdoor air concentrations of those pollutants.

These connections arise because in many cases the agents of concern are the same, and in many cases the sources of the agents are the same or intimately connected.For example, surface ozone is both an air pollutant and a greenhouse gas. The complex roles that ozone and aerosols play in the atmosphere provide examples of such trade-offs.

The enleanment due to oxygen in ethanol and the low volatility of the ethanol portion of the fuel blend at low temperature gives concerns that existing and planned vehicles designed for federal and California emissions test fuels will not meet their required emissions standards when operated on mid-level ethanol blends.

The largest systematic study ever conducted of human volunteers exposed to ozone air pollution has found no evidence of effects on the heart in its healthy, older participants, but did find effects on the volunteers’ ability to breathe, even at low ambient levels. Possible pathways by which ozone may cause adverse health effects.

Meanwhile, environmentalists were voicing concern—about how noisy such aircraft are taking off, about the possibility that their high-altitude emissions would erode the ozone layer, and about how disruptive the sonic booms would be. The last of these issues was perhaps the most vexing, prompting the U.S. Environmental Protection Agency.

A scholarly literature has documented this process in fields as diverse as engineering, risk reduction, management, and urban studies. The classic example of path dependence is the establishment of the conventional QWERTY keyboard standard on typewriters in the late 19th century and computers thereafter.
