摘　　要：本文研究了 0 0 1 0号台风“碧利斯”影响期间及其随后的恢复期中 ,厦门港湾中九龙江口和西港海域站表层海水总溶解砷 (TDIAs)、As3 + 含量和As3 + As5+ 值的变化特征 .结果表明 ,观测期间两站TDIAs和As5+ 含量均比非台风时期呈数倍增加 ,经1 0d后仍未恢复到非台风时的水平 .As3 + 含量也有较大幅度的增加 ,但波动较大 .文中还对观测期间影响溶解无机砷含量的因素进行了初步的探讨 .The variation characteristics of total dissolved inorganic arsenic(TDIAs),pentavalent arsenate(As 5+),trivalent arsenite(As 3+) and the ratio of As 3+/As 5+ in Jiulongjiang Estuary and Western Xiamen Harbor, and its relationships with some environmental factors under the influence of Typhoon Bilis have been studied. The results showed that the contents of TDIAs and As 5+ increased largely during the Typhoon Bilis and still maintained the high value after 10 days of 'recovery'. At the same time, the Typhoon Bilis also enhanced the content of As 3+, which have greater variation than that of As 5+.
