The knowledge on the migration of antimony (Sb) from PET bottles into the water is of greate concern. Antimony in all bottled water marketed in korea and in raw water was analyzed. The detection rate of antimony in total bottled water was 88 % and 100% in PET (Polyethylene terephthalate, PET), 55% in PC (Polycarbonate, PC) bottled water. 55% of raw water contained antimony. The average concentration of Sb in PET bottled water was 0.39 μg/L, higher than PC bottles (0.20 μg/L) and the raw water (0.22 μg/L). The migration of Sb into water that is stored in different conditions (room temperature, 45℃, and direct sunlight exposure) was investigated for 180 days. The migration tendency increased with the storage time and temperature. PET bottles showed a sharp increase of Sb concentration at 45℃, but there was no differences between the room temperature and sunlight exposure. The Sb migration in all simulated solution(deionized water, 4% acetic acid, and 20% ethanol) also increased with storage time and temperature. The Sb migration values ranged from 0.35 to 0.49 μg/L in all simulated solution, which was far below the permissible korean migration level of 40 μg/L. There was a tendency that the number of re-use of a bottle and the amount of leaching were in inverse proportion.

In this study, primary investigation for evaluation of abandoned metal mine effect on watershed has been done. 64 abandoned mines have been selected for primary investigation through literature and field survey. 216 soil and 90 water samples were collected and metal pollution concentrations were analyzed. 24 mines have mine water in the pits and acid water below pH 5 was not observed. Soils from 35 mines were over the soil basis of concern and 16 mines were over the soil basis of action. Arsenic average concentration was 188 times of average concentration of the natural background. Drinking water samples from 3 mines were over the drinking water standard and surface water samples from 12 mines were over the river water standard. Integrated pollution index, which was resulted from the integration of field survey, soil and water pollution concentration, showed that, abandoned metal mines had affected on watershed greatly in the order of Samgeum, Daedeok, Cheongdalgeum, Heungsin, Yeongdae and Myeongbong mines.
