| 目的 准确查明某型舰艇任务期间密闭舱室空气中挥发性有机化合物(VOCs)的浓度状况，并对多种VOCs采样方式进行对比测试研究。方法 分别采用苏码罐、Tenax TA管、DNPH管等3种采样方式对舰艇不同舱室部位的VOCs进行现场采样，在实验室回溯定量分析。结果 共检测出包括烷烃、芳香烃、烯烃、卤代烃、醇类、酯类、醛酮类等物质在内的39种VOCs组分，其中的12种具有较高浓度水平，达到102 μg/m3数量级以上。由于采样方式和原理的不同，检测出的VOCs种类数量和浓度含量存在差异，Tenax TA管和DNPH管的VOCs采样分析浓度普遍低于苏码罐，应当是由吸附过程中穿透导致。结论 在舰艇舱室环境VOCs测试研究中，需加强对检测结果的对比验证，注重多种采样分析方法的组合运用，实现采样分析能力的优势互补。 |

| This work aims to accurately determine the concentration of volatile organic compounds (VOCS) in the closed cabins during ship mission, a comparative test research was conducted on various VOCs sampling methods. The VOCs in different cabins of the ship were sampled on-site by three sampling methods of Summa canisters, Tenax TA tubes and DNPH tubes, and quantitative analysis were carried out in the laboratory. A total of 39 VOCs including alkanes, aromatic hydrocarbons, olefins, halogenated hydrocarbons, alcohols, esters, aldehydes and ketones were detected, 12 of which had higher concentration levels, reaching above the order of magnitude of 102 μg/m3. Due to the different sampling methods and mechanisms, there were differences in the number and concentration of detected VOCs. The concentration of VOCs of Tenax TA and DNPH tubes was generally lower than that of Summa canisters, which should be caused by penetration during adsorption. In the research of VOCs in ship cabin environment, it is necessary to strengthen the comparison and verification of the test results, pay attention to the combination of multiple sampling methods, and achieve the complementary advantages of sampling analysis capabilities. |
