2000 年 9 月至 2001 年 9 月期间，在土耳其伊兹密尔的一个石化联合体和一个炼油厂周围的三个采样点采集了空气样本，以测量环境中挥发性有机化合物 (VOC) 的浓度。 VOC 浓度比土耳其伊兹密尔郊区测得的浓度高 4-20 倍。二氯乙烷是石油精炼中使用的含铅汽油添加剂，也是石化企业氯乙烯工艺的中间产物，是最丰富的挥发性有机化合物，其次是乙醇和丙酮。基于风向的评估清楚地表明，测得的环境 VOC 浓度受到炼油厂和石化综合体排放的影响。所有采样点的 VOC 浓度均呈现季节性变化。夏季浓度最高，其次是秋季，这可能是由于气温升高导致挥发性有机化合物蒸发增加所致。 VOC浓度通常随着温度和风速的增加而增加。温度和风速共同解释了 VOC 浓度变化的 1-60%。无法用温度和风速解释的环境 VOC 浓度变化可归因于其他因素（即风向、其他 VOC 来源）的影响。 (C) 2003 Elsevier Science B.V. 保留所有权利。
Air samples were collected between September 2000 and September 2001 in Izmir, Turkey at three sampling sites located around a petrochemical complex and an oil refinery to measure ambient volatile organic compound (VOC) concentrations. VOC concentrations were 4-20-fold higher than those measured at a suburban site in Izmir, Turkey. Ethylene dichloride, a leaded gasoline additive used in petroleum refining and an intermediate product of the vinyl chloride process in the petrochemical complex, was the most abundant volatile organic compound, followed by ethyl alcohol and acetone. Evaluations based on wind direction clearly indicated that ambient VOC concentrations measured were affected by the refinery and petrochemical complex emissions. VOC concentrations showed seasonal variations at all sampling sites. Concentrations were highest in summer, followed by autumn, probably due to increased evaporation of VOCs from fugitive sources as a result of higher temperatures. VOC concentrations generally increased with temperature and wind speed. Temperature and wind speed together explained 1-60% of the variability in VOC concentrations. The variability in ambient VOC concentrations that could not be explained by temperature and wind speed can be attributed to the effect of other factors (i.e. wind direction, other VOC sources).
