摘要

在地中海东部一个受污染严重的工业城市(希腊的Aspropyrgos),研究了PM10对每日空气质量压力指数(AQSI)的贡献。为此,我们分析了2012年至2020年期间四种污染物(SO2、NO2、O3和PM10)的小时值,结果表明,空气质量指数的主要贡献者来自PM10(占每日空气质量指数的17%至90%),其年变化幅度适中,春季出现峰值。除PM10外,空气质量指数一直保持在0.8以下。为了确定PM10峰值的大气来源,对超过阈值的47个案例应用Flextra - Air质量轨迹模型。该模型的经验结果表明,主要来自撒哈拉沙漠的沙尘输送事件对PM10的日水平有贡献,并对AQSI有贡献。

PM10 and the air quality stress index in an industrial city of Eastern Mediterranean
The contribution of PM10 to the daily Air Quality Stress Index (AQSI) was examined in a heavily affected industrial city of Eastern Mediterranean (Aspropyrgos, Greece). For this purpose, hourly values of four pollutants (SO2, NO2, O3, and PM10) were analyzed between 2012 and 2020, revealing that the main contributor to AQSI levels came from PM10 (between 17% and 90% to the daily AQSI), with a moderate annual variability and a spring peak. Excluding PM10, the AQSI always remained below the threshold of 0.8. To identify the atmospheric source of PM10 peaks, the Flextra - Air mass trajectories model was applied to 47 cases when the upper thresholds were exceeded. The empirical results of the model show that dust transport episodes, mainly from Sahara Desert, contribute to the daily levels of PM10 and, for generalization, to AQSI.
