采用气相液相色谱-质谱联用法测定了塔玛河表层沉积物和河水中的线性烷基苯磺酸盐（LAS）。河流沉积物中LAS同系物的组成与河流水体中LAS同系物的组成有显著差异；沉积物中C12和C13 LAS的比例高于水中，而C10和C11 LAS的比例较低。随着烷基碳数的增加，沉积物中LAS同系物与水中LAS同系物的浓度之比呈指数增长。
Linear alkylbenzene sulfonates (LAS) in the surface sediment and the river water of the Tama River were determined by combined gas liquid chromatography and mass spectrometry. The composition of LAS homologues in the river sediment was remarkably different from that in the river water; the proportions of C12 and C13 LAS in the sediment were higher than those in the water, while those of C10 and C11 LAS were lower. The ratio of the concentration of the LAS homologues in the sediment to that in the water increased exponentially with increasing the carbon number of the alkyl group.
