1. In the previous report, the authors found that the activity of chlorotetracycline (CTC) is reduced in the service water and suggested that the active chlorine in the water might be responsible for it. The hypothesis is tested in the present study. 2. Both iron and calcium, at their levels in the service water respectively, did not affect the activity of CTC. Since CTC was stable also in the sea water, it might be safely inferred that not only iron and calcium but the metals present in the service water do not affect CTC. 3. The use of the service water, which was previously added with some chlorine consuming substances such as vitamin C, Na-nitrite, Na-sulfite, citric acid or tartaric acid made it possible to prevent the decrease in CTC activity. Among these substances, vitamin C, Na-nitrite, Nasulfite, and Na-thiosulfate were more effective in removing the active chlorine than citric acid or tartaric acid. These acids, especially the latter is slow in the reaction with the chlorine, which needs the light-treatment.
