To investigate the pollution characteristics of VOCs in the core area of the Ili River Valley, samples were collected at three typical industrial parks during 2021–2022. The emission characteristics of volatile organic compounds (VOCs), ozone formation potential (OFP) and secondary organic aerosols formation potential (SOAFP) were analyzed, and the health risks for residents were assessed. The results showed that the average TVOCs concentrations in the ambient air of the parks were 189.9±172.1, 129.3±56.0 and 426.4±155.9 μg/m³ for spring, summer and winter. OVOCs was the major component of VOCs for spring and summer with the contribution of 35%−43% and 30%–47% respectively for three industrial parks, while alkane was the primary contributor (64%–70%) for winter. The average OFP of VOCs was 494.5 μg/m3, with OVOCs (19%–47%), aromatics (24%–28%) and isoprene (12%–29%) being the major components. Among them, isoprene, toluene, xylene and methyl methacrylate were the primary reactive species. The average yield of SOAFP was 1.9 μg/m³ and aromatics had a dominant contribution (88%−93%). Toluene, xylene, benzene and ethylbenzene are key species. A potential non-carcinogenic risk from ambient VOCs should be considered for residents living around parks, mainly caused by acrolein. The average lifetime carcinogenic risks (LCR) of benzene, chloroform, tetrachloroethane, 1,2-dichloroethane and 1,2-dibromoethane were above the acceptable level (10⁻⁶), indicating a carcinogenic risk for these species. M/p-Xylene, o-Xylene, and dodecane were key precursors for the collaborative prevention and control of PM_2.5 and O₃. 

为深入探究伊犁河谷核心区工业园区环境中的VOCs污染特征, 于2021-2022年对3个园区环境进行VOCs采样与组分分析, 并估算 VOCs对臭氧生成潜势OFP和二次有机气溶胶生成潜势SOAFP的贡献, 同时进行健康风险评估, 以便全面地评估其环境与人体健康效应。结果表明, 春、夏、冬三季园区环境空气中总挥发性有机物TVOCs的平均浓度分别为189.9±172.1, 129.3±56.0和 426.4±155.9 μg/m³。烷烃是冬季各园区TVOCs质量浓度的主要特征组分(64%∼70%), OVOCs是夏季和春季TVOCs质量浓度贡献最高的组分, 贡献率分别为35%∼43%和30%∼47%。园区的OFP均值为494.5 μg/m³, 其中OVOCs (19%∼47%)、芳香烃(24%∼28%)和异戊二烯(12%∼29%)是OFP的主要贡献组分, 主要的活性物种为异戊二烯、间/对-二甲苯和甲基丙烯酸甲酯。园区的SOAFP平均生成量为1.9 μg/m³, 以芳香烃的贡献为最大(88%∼93%), 甲苯、二甲苯、苯和乙苯等为关键物种。各园区环境 VOCs对人体存在潜在的非致癌风险主要由丙烯醛引起。苯、三氯甲烷、四氯乙烷、1,2-二氯乙烷和1,2-二溴乙烷的平均终生癌症风险(lifetime carcinogenic risk, LCR)均大于10^–6, 表明可能存在潜在的致癌风险。研究显示, 间/对-二甲苯、邻-二甲苯和十二烷是协同防控该地区PM_2.5和O₃的关键前体物。
