%X Influence of microorganism for polycyclic aromatic hydrocarbons (PAHs) sorption on surface sediments and soils in Yellow River Delta was studied. The results indicated that phenanthrene and benzoa]pyrene could be adsorbed or biodegraded by microorganism, and 98% phenanthrene and 85% benzoa]pyrene was eliminated by microorganism in adsorption process. Sorption isotherms of soils and sediments with and without Microorganism were described by linear isotherm equation. Adsorption capacity of samples with microorganism increased about 35 times than that of without microorganism, but benzoa]pyrene adsorption capacity decreased about 3 times. In desorption process, samples with microorganism desorbed less phenanthrene than without microorganism, but more benzoa]pyrene. Microorganism plays an important role in adsorption process.
