Abstract：Static chamber is commonly used to detect the release flux of gaseous pollutants from soil. In order to clarify the characteristics of volatile organic compound （VOC） release from contaminated soil in the static chamber， the effects of VOC types， VOC contents in soil， air temperature and air disturbance on VOC release flux were investigated in this study. The results showed that the VOC concentration in the static chamber tended to balance or decrease within 5 min. The VOC concentration profile by first 30s was selected to calculate the VOC release flux. The VOC release flux in the static chamber is significantly negatively correlated to its lgKow value and molecular weight. The VOC release flux will increase by the increment of VOC content in the soil. The VOC release flux was also positively correlated to the air temperature. This demonstrated that air temperature should be accounted when detecting the VOC release flux. The VOC release fluxes in the static chamber with different numbers of fans were compared and the VOC release flux when using one fan was the largest. Therefore， using one fan in the static chamber is suggested to homogenize the VOC in the chamber. This study showed effects of main influencing factors on VOC release flux from the soil in a static chamber， which can provide scientific support for evaluation of the VOC release capacity and its risk control for contaminated soils.
