Abstract: Volatile organic compounds （VOCs） are currently the core atmospheric pollutants， and the emission of VOCs during the production and use of coatings has always been concerned. Through analyzing the SPECIATE database of United States Environmental Protection Agency， the application of SPECIATE database in screening the priority VOCs of coatings industry was studied. The appropriate screening principles， procedures and methods were established， and the scoring criteria and quantitative treatment methods of VOCs were proposed. 15 kinds of coating processes were selected. Taking mass fraction， odor threshold， saturated vapor pressure， ambient multimedia environmental goal and maximum incremental reactivity as evaluation parameters，7 kinds of priority VOCs in the coatings industry were identified by grading assignment and multi-parameter comprehensive evaluation. The status quo of implementation standards for priority VOCs was investigated and compared. The revised recommendations were proposed.

摘要： 挥发性有机物（VOCs）是当前核心大气污染物，而涂料的生产和使用过程中VOCs的排放一直得到关注。文中基于美国EPA的SPECIATE数据库和实际企业调研，研究了涂料行业重点VOCs的筛选原则与方法，确定VOCs的评分标准和量化处理方法；选取15个类型的涂料涂装工序，以质量分数、嗅阈值、饱和蒸气压、空气环境目标值和最大增量反应活性为评估参数，采用分级赋值和多参数综合评分筛选出7种（类）涂料行业重点VOCs。对重点VOCs的执行标准现状进行了调研比较，提出了修订的建议。
