The dismantling of electrical and electronic waste (e-waste) can release various Volatile organic compounds (VOCs), impacting the surrounding ambient environment. We investigated the spatio-temporal characteristics and health risks of the ambient VOCs emitted in a typical e-waste dismantling region by conducting multi-site sampling campaigns in four seasons. The pollution of benzene, toluene, ethylbenzene, and xylenes (BTEX) in the e-waste dismantling park has relation to e-waste dismantling by seasonal trend analysis. The highest concentrations of most VOCs occurred in winter and autumn, while the lowest levels were observed in summer and spring. The spatial distribution map revealed the e-waste dismantling park to be a hotspot of BTEX, 1,2-dichloropropane (1,2-DCP), and 1,2-dichloroethane (1,2-DCA), while two major residential areas were also the hotspots of BTEX. The e-waste emission source contributed 20.14% to the total VOCs in the e-waste dismantling park, while it was absent in the major residential and rural areas. The cancer risk assessment showed that six VOCs exceeded 1.0 × 10⁻⁶ in the e-waste dismantling park, while only three or four compounds exceeded this risk in other areas. The noncancer risks of all compounds were below the safety threshold. This study supplements the existing knowledge on VOC pollution from e-waste dismantling and expands the research scope of chemical pollution caused by e-waste.

拆除电气和电子废物（电子废物）会释放出各种挥发性有机化合物（VOC），从而影响周围的周围环境。我们通过在四个季节进行多站点采样活动，调查了典型电子废物拆解区域中排放的环境VOC的时空特征和健康风险。电子废弃物拆解园区内苯，甲苯，乙苯和二甲苯（BTEX）的污染与电子废弃物的分解之间存在季节性趋势分析。大多数挥发性有机化合物的最高浓度发生在冬季和秋季，而在夏季和春季则最低。空间分布图显示，电子废物拆解园区是BTEX，1,2-二氯丙烷（1,2-DCP）和1,2-二氯乙烷（1,2-DCA）的热点，而两个主要的居民区也是BTEX的热点。电子废物排放源占电子废物拆解园区总VOC的20.14％，而主要居民和农村地区则不存在。癌症风险评估显示，六个VOC超过1.0×10在电子废物拆解公园中，^-6，而在其他地区，只有三到四个化合物超过了这种风险。所有化合物的非癌风险均低于安全阈值。这项研究补充了现有的电子废物分解中有关VOC污染的知识，并扩大了由电子废物引起的化学污染的研究范围。
