An estimation of hydrocarbon emissions caused by the consumption of liquefied petroleum gas (LPG) in the Metropolitan Area of Mexico City (MAMC) is presented. On the basis of experimental measurements at all points of handling, during the distribution process, and during the consumption of LPG in industrial devices and domestic appliances, an estimated 76,414 tons/year are released to the air. The most important contribution is found during the domestic consumption of LPG (70%); this makes the control initiatives available to the consumer. By developing a control program of LPG losses, a 77% reduction in emission is expected in a 5-yr period. The calculated amounts of LPG emissions when correlated with the consumption of LPG, combined with information from air samples from the MAMC, do not point to LPG emissions as the most important factor contributing to tropospheric ozone in the air in Mexico City.
本文对墨西哥城大都市区（MAMC）液化石油气（LPG）消费所产生的碳氢化合物排放进行了估算。基于在LPG装卸、配送过程以及工业设备和家用电器使用过程中各环节的实验测量数据，估计每年有76414吨LPG排放到空气中。其中，家庭LPG消费的排放贡献最为显著（占70%）；这为消费者提供了控制措施。通过制定LPG损失控制计划，预计在5年内排放量可减少77%。将计算得出的LPG排放量与LPG消费量相关联，并结合来自MAMC的空气样本信息，结果表明LPG排放并非导致墨西哥城空气中对流层臭氧的最重要因素。
