摘要：The distribution of contents of sodium n-alkylbenzenesulfonate (LAS) was investigated in the sediments of the Sagami River Estuary and its adjacent sea areas to discuss the relationship between the null points of sediment and the points where LAS was detected. Further the compositions of homologous series of LAS, sodium n-decylbenzenesulfonate (C₁₀-LAS), sodium n-undecylbenzenesulfonate (C₁₁-LAS), sodium n-dodecylbenzenesulfonate (C₁₂-LAS) and sodium n-tridecylbenzenesulfonate (C₁₈-LAS), in the sediments and in the river waters were compared. The contents of LAS were determined by combined methylene blue colorimetry and infrared spectrometry, and then homologous series of LAS were determined by high-performance liquid chromatography. LAS was contained over the range of dry weight 5.5 to 17μg/g at 3 points among 10 points in the estuary, but not detected in the sea areas. The null points of sediment which were presumed from particle size distribution and from ignition loss in the estuary nearly agreed with the points where LAS was detected. In the sediments C₁₂-LAS was the most abundant among homologous series of LAS and its average percentage was 59, and C₁₀-LAS was absent. On the other hand, in the river waters C₁₁-LAS was 50% and C₁₃-LAS was not detected. These facts were considerably different from the percentage of compositions of LAS in the commercial detergent.
