Aviation is a basic necessity of our world, but its contribution to air pollution is considered significant. In this paper, the contribution of air traffic to air pollution levels in the area of the three larger airports of Greece is examined through the use of EDMS (Emission and Dispersion Modeling System), a regulatory model proposed by the US EPA (United States Environmental Protection Agency). To ensure a better understanding of air traffic contribution to air quality levels, the hourly aircraft movements along with the corresponding meteorological data for a whole year, 2009, were taken into account. During this year, air traffic peaked both in Greece as a total and in each of the three airports of this work. Airport emissions calculated by EDMS are found to be in good agreement with emissions monitored at Athens International Airport as well as with emission results and published data for International Zurich Airport. Concentration results have shown that PM₁₀ and SO₂ concentrations are well below the limit values, whereas NO₂ concentrations exceeding limit value are expected in small areas under specific circumstances, when heavy air traffic coincides with meteorological conditions favoring air pollutant accumulation. Finally, the comparison of computational results with monitoring air quality data shows a good agreement, if other sources of air pollution are excluded.

航空是我们世界的基本必需品，但它对空气污染的贡献却被认为是重要的。在本文中，通过使用EDMS（排放和扩散模型系统）检查了希腊三个较大机场区域内空中交通对空气污染水平的贡献，EDMS是美国EPA（美国环境署）提出的一种监管模型。保护局）。为了确保更好地了解空中交通对空气质量水平的影响，我们考虑了2009年全年的每小时飞机起降量以及相应的气象数据。在这一年中，这项工作在希腊和三个机场中的空中交通总量达到了峰值。通过EDMS计算得出的机场排放与雅典国际机场监控的排放以及苏黎世国际机场的排放结果和公布的数据非常吻合。浓缩结果表明，PM₁₀和SO _2的浓度远低于限值，而在特定情况下，当高空交通与有利于空气污染物积累的气象条件相吻合时，在小范围内NO ₂浓度有望超过限值。最后，如果排除其他空气污染源，则将计算结果与监测的空气质量数据进行比较可以得出很好的一致性。
