江门市人为源挥发性有机物排放清单

将江门市人为源挥发性有机物(VOCs)排放分为工业源、移动源、生活源和农业源四大类,以2014年为基准年,根据江门市的统计数据和实地调研结果,采用"自上而下"和"自下而上"结合的排放因子法建立了江门市人为源VOCs排放清单.结果显示江门市2014年人为源VOCs排放总量约为75.09 kt,工业源、移动源、农业源和生活源VOCs排放量为41.37、19.16、11.07和3.50 kt,占比分别为55.09%、25.51%、14.74%和4.65%.工业源中摩托车制造、集装箱制造、涂料、油墨、颜料及类似产品制造、印刷及包装印刷、塑料及橡胶制品、人造革制造、皮革鞣制加工、化石燃料燃烧、基础化学原料制造、电子制造、胶黏剂制造、家具制造等行业的VOCs排放量均超过1 000 t,为江门市重点VOCs排放行业.江门市蓬江区、江海区、鹤山市这3地以工业源排放为主,占比均超过50%,而恩平市、台山市等地则以农业源排放为主.各区和县级市在进行VOCs减排政策制定时要针对本土化的VOCs清单特征,进行精细化管控,才能取得较好减排效果.

Emission Inventory of Anthropogenic VOCs in Jiangmen City

Anthropogenic VOC emissions are classified into four sources:industrial, mobile, life, and agricultural. An anthropogenic VOC emission inventory in Jiangmen for 2014 was developed using both "top-down" and "bottom-up" emission factor methods, based on statistical survey data. The results showed that the total anthropogenic VOC emissions in Jiangmen were 75.09 kt. VOC emissions from the industrial, mobile, life, and agricultural sources were 41.37, 19.16, 11.07, and 3.50 kt, respectively, which contributed 55.09%, 25.51%, 14.74%, and 4.65% of the total anthropogenic VOC emissions. Motorcycle manufacturing, container manufacturing, coating, printing ink, manufacturing of paint and similar products, printing and packaging printing, plastics and rubber products, artificial leather manufacturing, leather tanning, burning of fossil fuels, manufacturing of basic chemical raw materials, electronics manufacturing, adhesives manufacturing, and furniture manufacturing are key industries in Jiangmen, each of which emit more than 1000 t of VOCs annually. The main emission sources in Pengjiang, Jianghai, and Heshan are industrial, which account for more than 50% of emissions in each of these districts, whereas the main emission sources in Enping and Taishan are agricultural. Districts and county-level cities will be able to achieve better emission reduction by using the local VOC inventory in the formulation of VOC emission reduction policies.
