摘　　要：The changes in heme (associated with hemoglobin), hemoglobin and hematin in the coelomic fluid of marine worm, Urechis unicinctus, exposed to different concentrations of sulfide, were investigated using bio- chemical techniques. When exposed to different sulfide concentrations for up to 96 h, the relative amounts of the three components changed in a regular pattern suggesting that the coelomocytes play an important role in the worm’s tolerance to sulfide. The possible roles of heme compounds in sulfide tolerance of this species are dis- cussed on the basis of our experimental data.The changes in heme （associated with hemoglobin）, hemoglobin and hematin in the coelomic fluid of marine worm, Urechis unicinctus, exposed to different concentrations of sulfide, were investigated using biochemical techniques.
