PROBLEM TO BE SOLVED: To provide a method and an apparatus for easily and rapidly analyzing dioxin in the atmosphere, exhausted gas and soil. SOLUTION: Sample gas is introduced in a sampling tube 4, and a sampling agent filled within the sampling tube 4 adsorbs dioxins and furans contained in the sample gas, and then the sampling tube 4 is took out and heated in a heater 8, and thereby the adsorbed dioxins and furans in the sample gas are eliminated from the sampling agent and detected using a gas chromatography 9. The quantitative analysis about the quantity of the dioxins including chlorine with number seven and/or eight is carried out, and the TEQ(toxic equiponderance) of the dioxins is obtained from a calibration line prepared beforehand representing the correlation between the content of the compounds and the TEQ of all dioxins. The quantitative analysis can be carried out using particulate matters as the sampling agent having the surface area of 5-50 m2/g and being made of heat-resistant resin, carbon black or their mixture.
