| Abstract: | The geochemical characteristics of rare earth elements (REEs) in intertidal sediments in Tianjin coastal zone were systematically studied. The environmental behaviors of REEs in polluted river were also examined. The source of REEs in intertidal sediments was discussed on the basis of distribution pattern of REEs. The results can be summed up in the following aspects: (1) The average content of total REEs in the intertidal sediments is 164.5 mg*kg-1, and different in different sections of the coast. (2) Residual REEs in the coastal zone decrease from north to south, and Fe-Mn oxides and organic matter-bound REEs increase. Compared with those in Changjiang River, ratio between residual and carbonate REEs is obviously low. (3) Distribution patterns of REEs show that light REEs is relatively high and Eu-anomaly is slightly negative. They are similar to the patterns in coastal and inland rivers and different from those in continental shelf. |
