Based on the observations and research results in engineering seismology for many years,the influence of artificial and natural factors produced in the field sampling on the observation of Hg content in soil gas is expounded.A method for getting over the influence factors is discussed.In study of engineering seismology,rational sampling depth and volume are introduced for observing Hg content in soil gas.
