| 中文摘要 |
| 以现阶段国内外重点关注的挥发性化学品(VCP)使用源全挥发区间有机物(FVOC)排放为对象,建立了系统的中国VCP使用源四级分类系统和FVOC排放核算方法体系,构建了2000~2020年中国VCP使用源FVOC排放清单,揭示了其FVOC排放时空演变特征,并对VCP控制提出了方向性的对策建议. 结果表明,2000~2020年中国VCP使用源FVOC排放呈现先上升后下降的趋势,2018年达到峰值. 2020年FVOC排放量为809.6万t,相对2000年增长了359%,主要与日益增长的市场消费需求和缺乏有效的FVOC综合治理措施有关. 涂料、农药和黏合剂是FVOC贡献较大的VCP类别,贡献率分别24%~61%,8%~34%和14%~18%. 2000~2020年涂料、油墨、黏合剂和农药FVOC排放均呈现先上升后下降的趋势(峰值出现年份不同),沥青和日用消费品FVOC排放整体呈现上升的趋势. 从三级排放源看,通用防腐涂料、凹版印刷油墨、建筑和室内装饰装修、除草剂、建筑常温应用沥青和空气清洗剂分别是涂料、油墨、黏合剂、农药、沥青和日用消费品FVOC排放贡献最大的化学品. 2000~2020年,VCP使用源空间FVOC平均排放强度随时间逐渐增加,2020年排放强度约为2000年的4.6倍,VCP使用源FVOC排放空间分布随时间变化较集中,主要分布在长三角地区,珠三角地区、山东、四川、湖南和湖北地区等. 2020年江苏、山东、湖北、浙江和广东是贡献最大的5个省域,合计贡献率46.8%. 建议试行重点贡献VCP产品全面监管替代监督抽查,实行VCP“生产-流通-使用”全环节产品源头监管,以及将I/SVOC指标逐步纳入VCP管控标准. |

| This study established a systematic four-tier classification system for volatile chemical product (VCP) use sources in China and developed a comprehensive full-volatility organic compound (FVOC) emission accounting methodology, focusing on FVOC emissions across the entire volatility range from VCP use sources. Based on this framework, a detailed FVOC emission inventory for Chinese VCP use sources from 2000 to 2020 was constructed, revealing spatiotemporal characteristics and proposing directional countermeasures and suggestions. The results indicated that China's FVOC emissions from VCP use sources exhibited an initial increase followed by a decrease from 2000 to 2020. Emissions rose continuously from 2000 to 2018, peaking in 2018 before declining. By 2020, FVOC emissions reached 8 096 kt, representing a 359% increase compared to 2000 levels. Paints, pesticides, and adhesives were the major contributing VCP categories, accounting for 24%-61%, 8%-34%, and 14%-18% of total emissions, respectively. While FVOC emissions from paints, inks, adhesives, and pesticides showed trends of initial increase followed by decrease (with varying peak years), emissions from asphalt and consumer products demonstrated continuous growth. At the tertiary source level, general anti-corrosion paints, Gravure printing inks, architectural and interior decoration, herbicides, architectural asphalt (ambient application), and air fresheners were the VCP types that contributed the most to FVOC emission respectively. Spatially, the average FVOC emission intensity from VCP use sources gradually increased from 2000 to 2020, reaching approximately 4.6 times the 2000 level by 2020. Emissions exhibited a concentrated geographical distribution over time, primarily located in the Yangtze River Delta, Pearl River Delta, Shandong, Sichuan, Hunan, and Hubei regions. In 2020, Jiangsu, Shandong, Hubei, Zhejiang, and Guangdong were the top five contributing provinces, collectively accounting for 46.8% of total emissions. This study proposes a three-tiered regulatory optimization framework for volatile chemical products (VCPs): ① replacement of conventional sampling-based supervision with comprehensive monitoring systems for critical VCP commodities; ② implementation of source-to-end lifecycle regulation spanning production, distribution, and utilization phases; and ③ systematic integration of I/SVOC metrics into evolving VCP regulatory benchmarks. |
