BAC SP #2 National Academy Of Sciences Chapter 4 Understanding Airport Air Quality And Public Health Studies 0001

Understanding Airport Air Quality and Public Health Studies Related to Airports CHAPTER 4 Health Impacts This chapter serves as a primer on understanding potential air pollutant health impacts and health risks. 4.1 Pollutant Health Impacts Overview Each of the pollutants targeted in this report can be categorized as either a criteria pollutant or a hazardous air pollutant (HAP). HAPs are also referred to as air toxics or as both criteria pollutants and HAPs (e.g., Lead, Pb, is regulated as a criteria pollutant but Pb-based compounds are on the EPA’s HAPs list). Each of these pollutants has health effects that range from mild to severe chronic and acute health effects, as well as premature death. Figure 4- 1 provides an overview of the population proportions associated with the severity of health effects–in general, the more severe the effect, the smaller the proportion of the population affected. The figure describes different degrees of health effects, and it should be understood that different poHut- ants will have different health impacts and levels of severity. The following sections describe the potential health effects of each pollutant. There are six (6) criteria pollutants. A discussion of concerns over their public health impacts follow: e Carbon monoxide (CO) is a colorless and odorless gas that can cause various physiological damages by displacing oxygen in the bloodstream. At high concentrations, CO has known health effects including dizziness, unconsciousness, and death. At lower concentrations more typical of ambient settings in the United States, individuals with cardiovascular disease are…
