UNASSIGNED: In-situ real-time monitoring of volatile organic compound (VOC) exposure and heart rate variability (HRV) were conducted for eight @entity18212 ( @entity18212 ) @entity1 using a VOC monitor, a Holter monitor, and a time-activity questionnaire for 24 h to identify the relationship between VOC exposure, biological effects, and subjective symptoms in actual life. The results revealed no significantly different parameters for averaged values such as VOC concentration, @entity2198 ( @entity2198 ), and @entity4365 ( @entity4365 ) to @entity2198 ratio compared with previous data from healthy subjects (Int. J. Environ. Res. Public Health 2010, 7, 4127-4138). Significant negative correlations for four subjects were observed between @entity2198 and amounts of VOC change. These results suggest that some @entity1 show inhibition of parasympathetic activities along with VOC exposure as observed in healthy subjects. Comparing the parameters during subjective symptoms and normal condition, VOC concentration and/or VOC change were high except for one subject. @entity2198 values were low for five subjects during subjective symptoms. Examining the time-series data for VOC exposure and @entity2198 of each subject showed that the subjective symptoms, VOC exposure, and @entity2198 seemed well related in some symptoms. Based on these characteristics, prevention measures of symptoms for each subject may be proposed.
