[Study on monitoring index of individual exposure dose of volatile organic compounds in environment].

In order to study the monitoring index of individual exposure dose of volatile organic compounds (VOCs) in environment, the thermal desorption capillary gas chromatographic (TD-GC) analysis was used to examine the VOCs level in air and the expired breath of female workers. Headspace solid phase micro-extraction gas chromatography (SPME-GC) was applied to determine the blood concentration of VOCs in female workers. The results from epidemiological study showed clearly that concentration of 10 subtypes of VOCs in blood, environmental air and expired breath from exposure group were higher than those from control group. The findings from the study suggested that the blood concentration of VOCs was sensitive and specific and this index might be one of good indexes in assessment of individual exposure dose of VOCs.
