本文建立了密闭舱室挥发性有机化合物（VOCs）被动式采集与非靶向测试方法。采用极性和非极性填料进行被动式采样，分析结果可互相对比且互为补充，采样方式简单、便携、稳定。运用目前先进的气相色谱-高分辨质谱（GC-HRMS）分析方法可高灵敏度、高分辨率鉴别采样中的VOCs组分，8个舱室采样位点共筛查出70种低浓度VOCs污染物。在得到的各类VOCs含量数据中，以多环芳烃（PAHs）这一类致癌性和致突变性污染物为例，根据含量热图分析获取多环芳烃在舱室中的分布规律，并推测其主要来源于机舱和设备舱中油料挥发以及厨房烹饪油烟。该方法的建立将更加高效、准确筛查舱室VOCs组分并进行污染源解析，有助于舱室大气环境质量提升和舰艇战斗力生成。
In this study, the method of passive sampling and non-target analysis for volatile organic compounds (VOCs) in closed cabins is established. Using polar and non-polar fillers for passive sampling, the analysis results can be compared with each other and complement each other. This sampling method is simple, portable and stable. Using the current advanced gas chromatography-high resolution mass spectrometry (GC-HRMS), VOC components in the sample can be identified with high sensitivity and high resolution. A total of 70 low-concentration VOC pollutants are screened out at 8 sampling sites. Among the obtained VOC content data, taking the carcinogenic and mutagenic polycyclic aromatic hydrocarbons (PAHs) as an example, the distribution of PAHs in the cabins is acquired according to the content heat map analysis, and it is speculated that PAHs mainly originate from volatile oils in engine and equipment cabins and cooking fume in kitchen. The establishment of this method will screen VOCs in the cabins and analyze the source of pollution more efficiently and accurately, which will help improve the atmospheric quality of the cabin and generate the combat effectiveness of the ship.
