Abstract
The analysis for the fluoride contents of river water and industrial waste water in Seoul area has been carried out by the spectrophotometric method, from February to July, 1968. The results show that the average fluoride contamination is found to be in the range of $0.07{\pm}0.03{\sim}0.29{\pm}0.05$ mg/l. The reason for this contamination is discussed in detail.
