中国工业源挥发性有机物排放清单

以工业源挥发性有机物（VOCs）为研究对象，在前期建立的工业源典型污染源分类系统基础上，对污染源系统和重要污染源排放系数进行修正和更新，采用排放系数法建立了2018年我国工业源VOCs排放清单.结果表明，2018年我国工业源VOCs排放量为12698 kt.含VOCs产品的使用环节贡献最大，占工业源排放总量的59%.工业涂装、印刷和包装印刷、基础化学原料制造、汽油储存与运输和石油炼制是排放量贡献最大的5大污染源，占工业源排放总量的54%；广东、山东、浙江和江苏是工业VOCs贡献最大的4个省份，排放总量占工业源VOCs总量的41%.海南、宁夏、西藏、黑龙江和新疆这5个省单位工业增加值VOCs排放强度最大，均超过了80 t ·（亿元）^-1.大多数省份工业VOCs排放主要来自含VOCs产品的使用环节；采用Monte Carlo模拟2018年我国工业源VOCs排放清单95%置信区间不确定度为［-32%，48%］.

Industrial Volatile Organic Compounds (VOCs) Emission Inventory in China

An industrial volatile organic compounds (VOCs) emission inventory was developed in China in 2018. It was based on the emission factors method, using a revised and updated source classification system and emission factors of key industrial sources. Results showed that the total industrial VOCs emission in China in 2018 reached as high as 12698 kt. Processes using products containing VOCs were the largest contributors, accounting for 59% of the total emission. The industrial coating industry, printing, the basic organic chemical industry, gasoline storage and transport, and the oil refinery industry were the five largest emitters, accounting for 54% of the total emission. Guangdong, Shandong, Zhejiang, and Jiangsu were the four largest emission contributors, contributing to 41% of the total emission. Hainan, Ningxia, Tibet, Heilongjiang, and Xinjiang showed the largest VOCs emission intensities, with more than 80 t·(100 million yuan)^-1. Processes using products containing VOCs were the main emission contributors in most provinces. The uncertainty for the total industrial VOCs emission in 2018, based on a Monte Carlo simulation, was-32%, 48%] at the 95% confidence interval.
