摘要：SUMMARYThe P300 component of the auditory event-related brain potential was examined in a group of 11workers exposed to low levels of organic solvents in a paint factory and 11 unexposed controls beforeand after 3 weeks of summer vacation. The P300 latency time was found to be prolonged among theexposed workers compared to the reference group before the summer vacation, and to be significantlylonger before the vacation than after in the exposed group.The P300 component was also examined in a group of 85 seamen from chemical tankers, experiencingpeak exposures to organic solvents. They were compared to a reference group of unexposedseamen. Comparing these two groups, no difference was found in the P300 latency time. No relationshipbetween the P300 latency time and exposure was found in a multiple regression analysis, includingthe variables age, alcohol consumption, smoking and cerebral concussions.The study indicates the occurrence of an acute biological effect in the nervous system related toorganic solvent exposure, expressed by prolonged P300 latency time. This was found at very lowexposure levels and should be studied further.
