“…This study also underscores the great health benefits from stringent NO x emission reductions, although O 3 concentrations may increase. In a VOC-limited region, conventional wisdom to rely on the VOCs emission control as a tool for O 3 management is experiencing great challenges due to the diversity and widespread nature of the VOCs species, and especially after the low-hanging fruit has been picked ( Gao et al, 2021 ). In the long-term strategies, the deep reduction in NO x emission and a subsequent transition to a NO x -limited regime are promising for attaining the O 3 target ( Ou et al, 2016 ).…”

“…以国家"十五"科技攻关计划、 "十一五"863 重大项目课题、大气重污染成因与治理攻关、 国家重点研发计划等项目为依托,我国学者在大气排放源分类、排放清单定量表征、排放因子 和成分谱建立、前体物组分清单构建、时间与空间分配、不确定性分析、校验与评估等方面开 展了较为系统的方法学研究,初步发展形成了区域和城市高分辨率大气污染物排放清单建立的 方法体系 [10,11] 。2013 年,中国原环境保护部按照"规范统一、科学实用、轻重缓急、循序渐进" 的原则,提出了中国排放清单编制技术指南体系构建的基本思路,并于 2014 年到 2016 年之间, 在清华大学等单位的主编下,先后发布了专门针对 PM 10 、PM 2.5 、VOCs 和 NH 3 以及道路机动车、 非道路移动源、生物质燃烧源、扬尘颗粒物和民用煤燃烧的大气污染物源排放清单编制技术指 南 [16,17] ,初步形成了我国大气污染物排放清单编制技术支撑体系。排放清单编制逐步向规范化 和业务化迈进。针对日益增长的城市空气质量精细化管理与区域联防联控需求,原环境保护部 于 2017 年组织相关研究机构进一步编制了《城市大气污染物排放清单编制技术手册》和 《 "2+26"城市大气污染防治跟踪研究工作手册》 [10,11] [18] 。清华大学 Li 等人 [12] 在 2017 年发表的综述 文章中详细总结了主要污染源本地实测排放因子进展。然而,文章也指出我国电厂 PM 2.5 排放、 工业锅炉排放、工业溶剂排放、秸秆燃烧以及农牧源的排放因子依然匮乏或者存在较高的不确 定性。因此近年来,一些学者也针对本土化不足、更新滞后或缺失排放因子的超低燃煤电厂 [19,20] 、生物质燃烧锅炉 [21] 、机动车及其 NH 3 排放 [22] [23] 、溶剂使用源 [24,25] 和船舶 [26] 源等开展了排 放因子实测工作。近年来,我国学者也开始关注天然源异戊二烯 [27] 、土壤 HONO [28] 、人为源 HONO [28][29][30] 、燃烧源 Cl [31] 以及机动车 HCHO [32] 等关键前体物组分的排放测试,其中土壤 [33] 、机 动车 [30] 、船舶 [34] 、生物质燃烧 [35] 等重点源 HONO 排放因子已经基本实现本土化。通过大量测 试和调研数据的积累,我国已初步建立了可反应本土排放特征的、覆盖重点行业的排放因子, 并逐步精细到主要子行业和关键组分,逐步实现重点行业关键前体物本土排放因子的全行业覆 盖,基本摆脱了对国外排放因子数据库的依赖。 除了排放因子,我国在 VOCs 与颗粒物(Particulate matter,PM)成分谱方面也开展了大量 的本土测试,污染源逐步覆盖了工业源、交通运输源、溶剂使用源、生物质燃烧源、扬尘源、 餐饮源等主要 VOCs 与 PM 污染源 [36] ,建立了可反映中国本土 VOCs 和 PM 重点源排放特征的 成分谱数据集。在 PM 成分谱数据集方面,Liu 等人 [37] 建立的 CSPSS (China Source Profile Shared Service)成分谱数据库收录了超过 200…”

“…In the area of indoor air quality, studies on gaseous emissions from building materials are drawing increasing attention. During the decoration process, building materials such as adhesives emit large amounts of volatile organic compounds (VOCs) [ 1 , 2 , 3 , 4 , 5 ], which are a major source of indoor air pollution. Since people spend approximately 80% of their lifetime in indoor buildings [ 6 , 7 ], long-term exposure to these VOCs can cause serious odor nuisance effects and negative health effects, leading to sick building syndrome (SBS) [ 8 , 9 , 10 , 11 ].…”
