| Abstract: | The contents of 29 elements in surface sediments from Bohai Bay were determined by neutron activation analysis. Based on a classification scheme, we divided these elements into six geochemical groups and discussed their distributions. Elements in the same group show similar distribution pattern. The chemical data of Bohai Bay sediments were compared with those of East China sediments, Okinawa Trough sediments, crust and continental shale. The correlation or difference were discussed with reference to their source terms and geochemical processer. The REE pattern based on eight rare earth elements we determined is very similar to the REE pattern of crustal materials. The presant data indicatethat the sediments are derived from continental materials carried and discharged by rivers.Based on As and Cr data, there is no noticeable contamination of the sediments. |
