Abstract:
Objective To investigate the pollution caused by the aerosols and variations of polycyclic aromatic hydrocarbons (PAHs) in a certain submarine cabins,and analyze the pollution source of PAHs,then to evaluate the toxicology of the contaminated submarine air.Methods Andersen cascade sampler was used to collect atmospheric particulate matter samples,during 6 days of continuous submergence of the submarine.The composition and variation of PAHs were analyzed by gas chromatography-mass spectrometry (GC-MS).Research on the main pollution sources of PAHs was made by using principal component analysis.Results Aerosol pollution in various cabins of the submarine was quite serious,furthermore it displayed the feature of pollution by different particle sizes.Particle size distribution analysis revealed that the 8-man cabin,meeting room,command room,torpedo room and engine room were of a unimodal size distribution,and the galley and hot air engine room displayed 3 relatively high peaks.Total PAHs were detected,with the concentration scope from 33.1 ng/m3 to 90.8 ng/m3 and with the 3-ring and 4-ring as the primary components.Total TEQ concentration ranged from 0.077 ng/m3 to 0.251 ng/m3.Conclusions Aerosol pollution in the cabins of the submarine was serious,with the cooking mist and volatile components of fuel as the main sources of PAHs and electrical appliances and laundry detergents as secondary source of pollution.
