目的：跟踪监测亚丁湾海域舰艇舱室空气微生物气溶胶浓度及粒径分布变化，为控制舰艇空气污染提供科学数据。方法采用安德森CA6型及CA2型撞击式空气采样仪，对舱室细菌气溶胶进行定量富集和粒径大小的分析。结果（1）调查区域细菌气溶胶浓度为102～103 CFU／m3。（2）51％～62％的舱室细菌气溶胶颗粒粒径大小为0．65～4．70μm。结论（1）所调查环境均处于相对较低的空气微生物污染水平，将粒径和某些条件致病菌一并作为评价因素，仍存在健康安全隐患。（2）应逐步建立各种舰船空气微生物环境的可接受污染阈值和评价体系，建立有效的净化消毒措施，以保证作业人员的健康。

Objective To monitor continuously the concentration and particle size distribution of bacterial aerosol in the cabins of a large vessel deployed in the Gulf of Aden , so as to provide scientific evidence for the control of ship air pollution .Methods With a CA6 and CA2 Andersen impact sampler , bacterial aerosol in the cabins was enriched quantively and particle sizes were analyzed accordingly .Results (1) The bacterial aerosol concentration in the survey areas was within the range of 102 -103 CFU/m3 .(2) The bacterial aerosol particle sizes in 51%-62%cabins were between 0.65 -4.7 μm.Conclusions (1) Although the microbial contamination levels in the survey area were relatively low , potential health and safety hazards still existed, provided particle sizes and certain conditional pathogenic bacteria were evaluated simutaneously .(2) Acceptable thresholds and evaluation systems for bacterial pollution in the cabin air of various ships , and effective purifying and disinfecting procedures should be established , so as to ensure the health of the ship crew .
