为探索新生产车辆车内空气中多环芳烃（polycyclic aromatic hydrocarbons, PAHs）的浓度水平及健康风险，通过使用颗粒物采样器与聚氨酯泡沫（polyurethane foam, PUF）套筒串联的方法，采集15台新生产乘用车在常温和高温光照2种工况下，车内气相和颗粒相的空气样品，通过GC-MS测定样品中16种优先控制的PAHs的含量，并进行驾乘人员健康风险评估。结果表明：16种PAHs在气相和颗粒相中的平均检出率为2.17 ~ 50.00，其中萘（Nap）、苊（Ace）和菲（Phe）在部分样车高温和常温工况下均有检出，而苊烯（Acy）在所有样车高温和常温工况下均有检出，其余物质仅在高温下检出；车内空气中PAHs的浓度在高温工况下高于常温工况，且气相中浓度高于颗粒相，整体上Nap的浓度最高；在高温工况下Nap、Ace、Phe、Acy的致癌健康风险为3.53 × 10^-11 ~ 4.54 × 10^-9，而在常温工况下为1.70 × 10^-11 ~ 5.16 × 10^-9。可见使用颗粒物采样器与聚氨酯泡沫（PUF）套筒串联采样的方法，能有效采集车内空气中气相和颗粒相中的PAHs，车辆车内空气中PAHs检出浓度较低，致癌健康风险整体<10^-6，致癌风险较低。

In order to explore the concentration level and health risks of polycyclic aromatic hydrocarbons (PAHs) in cabin of new cars, air samples of 15 newly produced passenger cars in the gaseous and particulate phases under normal temperature and high temperature conditions were collected by using particulate samplers in series with polyurethane foam (PUF) sleeves. The contents of 16 priority PAHs in the samples were determined by GC-MS, and the health risk assessment of drivers and passengers was carried out. The results show that the average detection rates of 16 PAHs in the gaseous and particulate phases is 2.17 ~ 50.00. Among them, naphthalene (Nap), phenanthrene (Ace), and phenanthrene (Phe) are detected in some sample cars under high and normal temperature conditions, while phenanthrene (Acy) is detected in all sample cars under high and normal temperature conditions, and the rest of the substances are only detected under high temperature conditions. The concentration of PAHs in cabin of cars under high temperature conditions is higher than that under normal temperature conditions, and the concentration in the gas phase is higher than that in the particulate phase. Overall, Nap exhibites the highest concentration. The carcinogenic health risks of Nap, Ace, Phe, and Acy under high temperature conditions range from 3.53 × 10^-11 to 4.54 × 10^-9, while under normal temperature conditions, they range from 1.70 × 10^-11 to 5.16 × 10^-9. It can be seen that PAHs in the gas phase and particulate phase in cabin of new cars, can be effectively collected by using particulate matter samplers in series with a polyurethane foam(PUF) sleeves for sampling. The detected concentrations of PAHs in cabin of cars, is low, the overall carcinogenic health risk is less than 10^-6, and the carcinogenic risk is low.
