Porto Alegre, 8th october. Airport related emissions and impacts on air quality: Application to the Atlanta International Airport Author: Alper Unal A presentation of Cristiano Hoffmann Meireles Year 2005 The goal of this study is to quantify the impact of aircraft emissions on regional air quality, especially in regards to PM2.5 and ozone. Objectives This presentation will be approached issues related emissions and impacts caused by aircraft in area of the Hartsfield–Jackson Atlanta International Airport. Air transportation plays a substantial role in global
economic activity and in the last decade air traffic has increased dramatically: 47 percent between 1991 and
2000 . The US environmental protection agency (EPA) estimated that airport emissions in 1999 as compared to 1970 are up more than 80 percent for volatile organic carbon (VOC) and nitrogenoxide (NOX) emissions doubled. Ground Support Equipment (GSE)
Measurements for ten days Methodology 56 ppb on ozone with a 5 ppb average impact over most of the Atlanta area. 25 mgm3 on PM2.5 with a 4 mgm3 avarege impact over most of the Atlanta area. Results suggest that Hartsfield–Jackson airport can have a maximum impact of: Conclusions Regarding the crescent aviation expansion the pollution rates are increasing and tend to grow even more therefore the PM2.5 and ozone levels must be watched. Although the airport area is small, the impact that is caused by the airport and its crescent expansion in relation with the air quality around it is really big. The results were expected, analyzing the size and flow of the airport.
Ozone and PM2.5 impacts at other times may be more or less, depending on meteorology.
The results,however, still have uncertainties and are limited by application to a 10-day period.
