Similarly, a cursory review of the scientific litera ture reveals a wide range of health outcomes -- cancer, pulmonary disease, cardiovascular disease, neurological effects -- in human populations exposed to environmental agents found in combustion products, singly and in mix tures. Comparable studies on laboratory animals often complement and supplement the data from human studies.

As shown in Figure 3-2, the process focuses first on research and data collection related to exposures at JBB, health effects that might result from those exposures, and health outcomes in other human populations exposed to some of the environmental agents found in ambient samples and potentially emit ted by the JBB burn pit. Based on this information, assessments are then made on potential exposures and health effects that might occur in relevant populations.

3. New study design: The exposure–response information developed in Chapters 5 and 6, combined with infor mation on the potential exposures of JBB personnel discussed in Chapter 4, provide the basis for evaluating feasibility and design issues specific to an epidemiologic study to assess health outcomes associated with exposure to burn pit emissions at JBB and other burn pit sites (see Chapter 8)

Based on the air monitoring data analyzed in Chapter 4, the committee determined the likely adverse health effects that might be associated with those chemicals found above the analytical detection limit or that otherwise were expected to pose the greatest risk to JBB personnel. To identify potential health effects from these exposures, the committee relied on published summaries from diverse sources, including IOM and NRC reports, government reports such as toxicological profiles from the Agency for Toxic Substances and Disease Registry, and established databases such as the U.S.

Populations of Interest Assessing potential future effects of exposure in a particular population such as JBB personnel depends on available information for that population together with observational data on effects in theoretically similar populations exposed under generally comparable conditions. Three occupational populations were of special interest to the committee because of their exposure to complex mixtures of combustion products potentially similar to burn pit emissions: firefighters (wildlands and urban)

The committee also considers the possible impact of co-exposure to combustion products from local and regional air pollution sources other than the JBB burn pit. NEW STUDY DESIGN The statement of task directs the committee to "examine the feasibility and design issues for an epidemiologic study of veterans exposed at the Balad burn pit." Two recent IOM reports on other military populations offer useful models.
