Orthogonal experimental is designed to determine using of L12 (6 * 22) orthogonal, the time is 12 hours and the temperature is 55 °C, dichloromethane amount of 200 ml to extract the best conditions, the best extraction conditions were eight of Jinan City A typical open-source Soxhlet extraction, the extract of the rotary Evaporation, chromatography purification after blowing nitrogen; using GC-MS determination of the content of polycyclic aromatic hydrocarbons. Through the eight kinds of samples of data comparison, the steel dust found in samples of the highest content of polycyclic aromatic hydrocarbons. With the strong carcinogen Dibenzo (a, h) anthracene, 16 in the highest levels of polycyclic aromatic hydrocarbons.
