Abstract: Alkyl Benzene Sulfonates (ABS) are anionic surfactants in synthetic detergents.
They are resistant to biological decay in natural waters and toxic if the concentrations are too high in
rivers. This study used a steady-state, simplified, analytical mathematical model to simulate the
distribution of ABS concentrations in Hsintien River. Laboratory tests on adsorption and desorption of
ABS were carried out using sediments from Hsintien River to obtain the partition coefficient for the
model. Through model calibration and validation, favorable results were obtained from model results by
comparing it with available measured ABS data from the river. Sensitivity analyses with varying model
parameters were also carried out. Partition coefficients and streamflows were found to be sensitive
parameters in determining the distribution of ABS in Hsientien River. The simplified models shown in
this paper are very useful for the prediction and management of toxic substances in rivers.
