摘要

石油工业是人为挥发性有机化合物(VOCs)的重要来源,但迄今为止,其对城市 VOCs 和臭氧(O3)的确切影响仍不清楚。本研究在中国东营这个石油工业地区进行了长达一年的挥发性有机化合物观测。采用正矩阵因式分解模型识别了石油工业(油气挥发和石油化工生产)产生的挥发性有机化合物,并利用基于观测的化学箱模型定量评估了它们对 O3 形成的贡献。观测到的挥发性有机化合物年平均浓度为 68.6 ± 63.5 ppbv,最大日平均浓度为 335.3 ppbv。石油工业产生的挥发性有机化合物占总挥发性有机化合物的 66.5%,其中 54.9% 来自油气蒸发,11.6% 来自石化生产。模型结果表明,石油工业产生的挥发性有机化合物占净臭氧产生量的 31%,对 HO2+NO 和 RO2+NO 途径的影响分别为 21.3% 和 34.2%。对 RO2 途径产生较大影响的主要原因是,OH+VOC 占 RO2 主要来源的 86.9%。这项研究强调了控制石油工业产生的挥发性有机化合物在城市臭氧污染中的关键作用,尤其是那些以前被忽视的低活性烷烃。摘要通过在黄河三角洲典型城市东营市一年的挥发性有机物 (VOCs) 观测,使用正交矩阵因子分解模型和化学盒子模型定量了石油工业对 VOCs 和臭氧污染的贡献。研究发现石油工业 VOCs 对总 VOCs 的贡献达 66.5%,其中油气挥发贡献 54.9%, 石油化工生产贡献 11.6%。石油工业VOCs对O3净生成速率的贡献达31%。这些结果揭示了石油工业在VOCs和臭氧污染等方面对城市空气质量的重要影响。

Significant contributions of the petroleum industry to volatile organic compounds and ozone pollution: Insights from year-long observations in the Yellow River Delta
The petroleum industry is a significant source of anthropogenic volatile organic compounds (VOCs), but up to now, its exact impact on urban VOCs and ozone (O3) remains unclear. This study conducted year-long VOC observations in Dongying, China, a petroleum industrial region. The VOCs from the petroleum industry (oil and gas volatilization and petrochemical production) were identified by employing the positive matrix factorization model, and their contribution to O3 formation was quantitatively evaluated using an observation-based chemical box model. The observed annual average concentration of VOCs was 68.6 ± 63.5 ppbv, with a maximum daily average of 335.3 ppbv. The petroleum industry accounted for 66.5% of total VOCs, contributing 54.9% from oil and gas evaporation and 11.6% from petrochemical production. Model results indicated that VOCs from the petroleum industry contributed to 31% of net O3 production, with 21.3% and 34.2% contributions to HO2+NO and RO2+NO pathways, respectively. The larger impact on the RO2 pathway is primarily due to the fact that OH+VOCs account for 86.9% of the primary source of RO2. This study highlights the critical role of controlling VOCs from the petroleum industry in urban O3 pollution, especially those from previously overlooked low-reactivity alkanes.
