Source-specific emission data were collected from fifteen representative facilities encompassing furniture manufacturing, automobile production, and chemical industries through a combination of on-site sampling and comprehensive literature review. Our results reveal distinct chemical signatures and regional variations among different source categories: furniture manufacturing emissions are dominated by alkanes (65%), chemical industries exhibit 51% alkane contribution, while automobile manufacturing demonstrates a remarkably high aromatic hydrocarbon content (64%), significantly exceeding other investigated sectors. Notably, aromatic hydrocarbons\u2014particularly benzene derivatives\u2014emitted from automotive manufacturing facilities pose potential carcinogenic and chronic health risks to both occupational workers and surrounding populations, necessitating prioritized regulatory intervention. These locally derived emission profiles fill a critical knowledge gap in regional VOC source characterization for Chongqing, providing essential scientific evidence for accurate source apportionment and formulation of sector-specific emission reduction strategies.<\/jats:p>","DOI":"10.3390\/toxics14020143","type":"journal-article","created":{"date-parts":[[2026,2,2]],"date-time":"2026-02-02T09:00:33Z","timestamp":1770022833000},"page":"143","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Source Profile Analysis of Atmospheric Volatile Organic Compounds in Chongqing"],"prefix":"10.3390","volume":"14","author":[{"given":"Anqi","family":"Zhang","sequence":"first","affiliation":[{"name":"State Key Laboratory of Environmental Criteria and Risk Assessment, Chinese Research Academy of Environmental Sciences, Beijing 100012, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xin","family":"Qi","sequence":"additional","affiliation":[{"name":"Chongqing University, Chongqing 400044, China"},{"name":"Research Center for Atmospheric Environment, Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences, Chongqing 400714, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuchun","family":"Jiang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Environmental Criteria and Risk Assessment, Chinese Research Academy of Environmental Sciences, Beijing 100012, China"},{"name":"Tianfu Yongxing Laboratory, Chengdu 610213, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hanfei","family":"Zuo","sequence":"additional","affiliation":[{"name":"Zhejiang Provincial Key Laboratory of Organic Pollution Process and Control, College of Environmental and Resource Sciences, Zhejiang University, Hangzhou 310058, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yang","family":"Chen","sequence":"additional","affiliation":[{"name":"Research Center for Atmospheric Environment, Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences, Chongqing 400714, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoqian","family":"Li","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Environmental Criteria and Risk Assessment, Chinese Research Academy of Environmental Sciences, Beijing 100012, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"26","DOI":"10.1038\/s44407-025-00020-x","article-title":"Understanding atmospheric processes: Insights from the comparison between Beijing and Hyyti\u00e4l\u00e4","volume":"1","author":"Kulmala","year":"2025","journal-title":"npj Clean Air"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"174108","DOI":"10.1016\/j.scitotenv.2024.174108","article-title":"Characterization of VOCs emissions and associated health risks inherent to the packaging and printing industries in Shandong Province, China","volume":"946","author":"Zhu","year":"2024","journal-title":"Sci.
