| Abstract: |
| 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. |
