摘要
代表旱雨季的4航次九龙江口硒的调研中，发现总溶解无机硒和Se（N）皆呈保守行为；溶解有机硒和颗粒氧化物硒则无甚规律可循。沉积物中有机硒与有机碳含量呈良好正相关关系。由流积相向上覆水体提供的溶解无机硒和有机硒的通量，分别为170和200nmol／（m2·月）。
The Se chemical behaviour ln the Jiulong Estuary has studied during 4 curises in the dryand rainy seasons- Both total dissolved inorganic Se and Se(Ⅳ ) in all the curises behavedconservatively, Dissolved organic Se and particulate oxide-Se concentrations scatter in the es tuary without any regular trend. Linear relationship of organic Se and organic carbon in sediments was observed. The dissolved inorganic and organic Se flux from the sediment to theoverlying water was estimated to be 170 and 200 n mol/(m2. month).
