High concentrations of volatile organic compounds (VOCs) in ambient air of urban areas stress the need for the control of VOC emissions due to the toxic and carcinogenic nature of many VOCs commonly encountered in urban air. Emission inventories are an essential tool in the management of local air quality, which provide a listing of sources of air pollutant emissions within a specific area over a specified period of time. This study intended to provide a level IV emission inventory as par the United States Environmental Protection Agency (USEPA) definition for evaporative VOC emissions in the metro cities of India namely Delhi, Mumbai, Chennai, and Kolkata. The vehicular evaporative emissions are found to be the largest contributor to the total evaporative emissions of hydrocarbons followed by evaporative losses related to petrol loading and unloading activities. Besides vehicle-related activities, other major sources contributing to evaporative emissions of hydrocarbons are surface coating, dry cleaning, graphical art applications, printing (newspaper and computer), and the use of consumer products. Various specific preventive measures are also recommended for reducing the emissions.
城市环境空气中高浓度的挥发性有机化合物（VOCs）强调了控制 VOC 排放的必要性，因为城市空气中常见的许多 VOC 具有毒性和致癌性。排放清单是管理当地空气质量的重要工具，它提供了在特定时间段内特定区域内空气污染物排放源的清单。本研究旨在根据美国环境保护署（USEPA）的定义，为印度的大都市（即德里、孟买、钦奈和加尔各答）提供挥发性有机化合物排放的第四级排放清单。车辆蒸发排放被发现是总碳氢化合物蒸发排放的最大贡献者，其次是与汽油装卸活动有关的蒸发损失。除了与车辆相关的活动外，其他对碳氢化合物蒸发排放有重大贡献的主要来源是表面涂层、干洗、图形艺术应用、印刷（报纸和计算机）以及消费产品的使用。还建议采取各种具体的预防措施来减少排放。
