| 摘 要： | This paper deals with the geochemical characteristics of arsenic in sediments from Bohai Gulf. The arsenic in seawater, surface sediments and cores is determined. Also measured are other physical and chemical parameters, such as Ni, Fe, C, pH and Eh in sediments. The values of As range from 0.6 to 4.5 ppb in seawater, from 10.0 to 20.9 ppm in surface sediments and from 6.8 to 22.8 ppm in cores.The contents of As from south are higher than those from north. However the As in sediments is the element not affected by pollution.The adsorption and codeposition of Ferric oxide colloid are the major form of transference of As from seawater to sediments in Bohai Gulf.The valence state of As in sediments is HAsO42-
