Description

The content of anionic surfactants in the inland sea-water of Eastern Seto, collected at 4 sampling points June 10-13, 1975, and at 17 points on October 25, 1976, were measured by the Methylene Blue method after clean-up procedure using Amberlite XAD-2 columns. It was observed in the samples collected in 1975 that the surfactants were concentrated by partition to the dispersing residual oil (mainly due to oil flowing out of a tank at Mizushima), resulting in high levels. On the other hand, the levels in most samples collected in 1976 ranged from 3 to 6 μg/l. Effect of surfactants in the sea on the fish was discussed on the basis of TLm values of the fish.
