新疆兵团某城市工业园区挥发性有机物污染特征及环境影响

Characteristics and Environmental Impacts of Volatile Organic Compound Pollution in an Industrial Park of a City in the Xinjiang Production and Construction Corps

摘要: 本研究系统评估了新疆兵团某典型工业园区大气VOCs的污染特征、环境效应及健康风险。结果显示，TVOCs年均浓度为(103.6 ± 92.6) μg/m³，夏季最高，OVOCs为全年主导组分(占43.5%)。VOCs年均OFP为3.81 μg/m³，主要贡献物种为丙烯和丙酮等；年均SOAFP为0.056 μg/m³，苯和甲苯贡献占比达81.0%。苯、甲苯和正己烷为O₃与PM_2.5协同控制的关键前体物。健康风险评价表明，VOCs非致癌风险较低，但萘、苯等存在潜在致癌风险，应作为优先管控物种。研究可为园区VOCs协同控制和重点物种管控提供科学依据。

Abstract: This study systematically assessed the pollution characteristics, environmental effects, and health risks of atmospheric VOCs in a typical industrial park in Xinjiang. The results show that the annual average concentration of TVOCs was (103.6 ± 92.6) μg/m³, with the highest levels in summer. OVOCs were the dominant components throughout the year (accounting for 43.5%). The annual average OFP of VOCs was 3.81 μg/m³, with propylene and acetone being the major contributing species; the annual average SOAFP was 0.056 μg/m³, with benzene and toluene contributing up to 81.0%. Benzene, toluene, and n-hexane were identified as key precursors for the coordinated control of O₃ and PM_2.5. Health risk assessment indicated a low non-carcinogenic risk from VOCs, but potential carcinogenic risks were identified for species such as naphthalene and benzene, which should be prioritized for control. This research provides a scientific basis for the coordinated control of VOCs and targeted management of key species in industrial parks.
