| 摘 要： | 根据胶州湾四个航次中水体的溶解态总砷c（AS）、溶解态三价砷c（AS（Ⅲ））、悬浮物总砷（Asp）、浮游植物总砷（Asph）、沉积物酸萃取态砷（SAsH）的调查数据，指出c（As）含量未超过国家一类海水水质标准，其高值区位于四方近岸，并由近岸向远岸浓度逐渐降低。由悬浮颗粒物、浮游植物和沉积物对水体中砷的富集因子，指出三者在砷的循环和迁移中起主导作用。

| Abstract: | This paper discusses the forms and transfer of arsenic in east Jiaozhou Bay based on the data of four cruises from Nov. 1990 to Aug. 1991. We determined the arsenic in the waters, suspended particulates, phytoplanktons and the upper sediments. The results show that the dissolved total arsenic c(As) concentration tallies with the National NO 1. Standard of Sea Water Quality, with its values higher near the coast of Sifang and gradually decreasing off the coast. The concentration factors of suspended particulate, phytoplankton and upper sediment are 196, 3320 and 777 respectively, which indicate that they pLay an important role in the cycling and transfer of arsenic in east Jiaozhou Bay. |
