Estimation the time of spill crude oil in deep soil by the detection of volatile organic compounds (VOCs)

摘要

Detection of volatile organic compounds (VOCs) was done by a large number of studies in different methods and techniques among them are passive samplers because of their unique specifications technically and economically. In this study, passive sampler technique was used for monitoring of VOCs from spill crude oils in deep soil. Mathematical equations were achieved for the determination of time spill crude oil which depends on soil moisture content, soil temperature, and wind speed. The mathematical equations were driven from monitoring VOCs during three months. The results illustrated that the concentrations of n-Pentane was inversely diffused when compared with n-Nonane.
