| What are the media concentration or exposure results? For example, what were the air concentrations used to estimate risks? What were the significant (perhaps maximum) air concentrations for HAPS without toxicological dose response values? |

|
| What are the individual cancer risk estimate results? An estimate of an individual's excess cancer risk from a lifetime of exposure are often developed using unit risk estimates (URE) that are based on a lifetime exposure of 70 years. For example, the lifetime individual risk from continuous breathing of current pollutant levels in California is estimated to be 760 in one million. These risks may be expressed as a single number, or as a range to indicate variation in exposure factors, chemical compounds, exposure location, emission rates, etc. |

 | What is the cancer risk estimate for the maximum exposed individual (MEI)? What HAPs drive the risk? MEI risks are estimated from the highest air concentration outside the facility fence line whether or not individuals reside there. |
|

|
|
| What is the maximum individual risk (MIR)? What HAPs drive the risk? MIRs are estimated from the highest air concentration outside the facility fence line where individuals reside. |

|
|
| What are the individual non-cancer risk estimates: MEI, MIR, worker? What HAPs drive the risk? |
|
|
|
| What are the target-organ specific hazard indices (TOSHI)? If they weren't developed, why not? |
|
|
|
| What are the population risk results? For both cancer and noncancer risks, the population risk is usually expressed as the number of people estimated to be at various levels of risk. Population cancer risk can also be expressed as the predicted increased incidence of cancer (that is, the number of new cases each year) for all people exposed to the pollutant. For example, the estimated population cancer risk may be the number of new cancer cases per year predicted among residents within 30 miles of a certain large source. |

| What other results were found as part of this project? An example is blood lead estimates for children's exposure to lead. |

|
| What pollutants were identified as being of concern? On what basis? What pollutants were found to contribute most to risk of adverse health effects or found in highest concentrations? |
|
| Criteria Pollutants, Greenhouse Gases, 13-Butadiene, Acrolein, Benzene- including benzene from gasoline, PAHs |
|
| What sources of pollution were identified as being of concern? For example, sources may be in the following categories: non-located area sources, located stationary sources, ambient area, road and non-road mobile sources, and diesel/gasoline sources. |
