  • Minerals play an important role in the body as essential nutrients. However, it is not easy to meet DRIs because food sources of minerals are limited. Recently, consumption of bottled natural water has been increasing in Korea due to water pollution and distrust of tap water. The present study was conducted to investigate mineral contents in bottled natural water and their intakes among Korean adults. We analyzed eight minerals in seven kinds of bottled natural water by ICP-spectrometry and conducted a survey on the intake status of water and bottled natural water with 400 Korean young adults. The mean contents of Ca, Mg, Fe, Zn, Cu, Mn, Se, and Mo in bottled natural water were 22.45${\pm}$22.48 mg/L, 10.59${\pm}$9.97 mg/L, 0.27${\pm}$0.18 ${\mu}g/L$, 2.06${\pm}$1.48 ${\mu}g/L$, 5.47${\pm}$0.70 ${\mu}g/L$, 1.43${\pm}$0.37 ${\mu}g/L$, 1.90${\pm}$0.96 ${\mu}g/L$, and 3.34${\pm}$0.79 ${\mu}g/L$, respectively. The mean age, height, weight, and BMI were 22.76 years, 174.94 cm, 68.64 kg, and 22.41 $kg/m^2$ for males (n=150) and 21.25 years, 162.04 cm, 51.05 kg, and 19.46 $kg/m^2$ for females (n=250), respectively. The respective daily intakes of total water and bottled natural water as water itself were 670.30 ml and 212.20 ml for males and 488.04 ml and 132.72 ml for females. The daily intakes of Ca, Mg, Fe, Zn, Cu, Mn, Se, and Mo from bottled natural water were 4.76 mg, 2.25 mg, 0.06 ${\mu}g$, 0.44 ${\mu}g$, 1.16 ${\mu}g$, 0.30 ${\mu}g$, 0.40 ${\mu}g$, and 0.71 ${\mu}g$ for males and 2.98 ${\mu}g$, 1.41 mg, 0.04 ${\mu}g$, 0.27 ${\mu}g$,0.73 ${\mu}g$, 0.19 ${\mu}g$,0.25 ${\mu}g$, and 0.44 ${\mu}g$ for females, respectively. Overall, the contents of Ca, Mg, and Se in bottled natural water were relatively high and the daily intakes of these minerals were 0.4~1.0% of the DRIs.

  • To assess possible risks from the consumption of drinking water from various sources, a survey of the microbiological quality of tap water, commercial bottled drinking water which is exploited from natural mineral water, and natural spring water was conducted. A total of 4 different brands of commercial bottled drinking water, and 4 types of spring water from different sources, and tap water from 4 private houses were tested for four index microorganisms, and the microbial quality changes of the water during the storage at room temperature or refrigerated temperature for 7 days. Aerobic plate counts of all of the initial water samples were still within 100 CFU/ml (drinking water standard of Korea). Total coliforms, fecal coliforms, and E. coli were not detected in all of the water samples at initial. However, aerobic plate counts of three types of spring water and three types of bottled drinking water stored at room temperature showed higher levels than the standards in 5 days. Total coliforms were detected in three types of spring water after one day's storage at room temperature, and in one type of bottled drinking water after 5 days' storage. These results indicate that some of the spring water surveyed are not safe to drink, and the spring water and bottled drinking water after opening the lid should not be stored at room temperature, if they are used for drinking.

  • In recent years, the sales of bottled spring water (BSW) have been drastically increasing in Korea and other countries, which accompanied great interests in conservation and reclamation of natural mineral water (NMW). In this study, management and research activities on NMW in Europe, USA, and Codex Alimentarius were reviewed. In each region, NMW is regulated with its own quality standards that differ from ordinary drinking water, and management actions are strictly implemented to protect water resources and to secure quality of NMW. Many studies on NMW were carried out for monitoring inorganic constituents including major and trace elements in national levels for bottled NMW, groundwater, and tap water in other countries. In Korea, NMW became commercialized in 1995 when BSW was legally approved as a drinking water. To further promote utilization of various types of NMW in Korea, regulations and policies for NMW need to be revised in accordance with international NMW management trends. Further, studies of NMW that compile a comprehensive set of physical and chemical parameters of NMW are also needed to properly understand occurrences, hydrogeological and geochemical processes of NMW, as well as to evaluate its potential use as a natural resource.

  • In recent years, there has been an increase in consumer demand for bottled waters. There is a perception that consumption of natural mineral water represents a healthy life style and that these products are relatively safe. In this study, the microbiological quality of 39 samples of bottled water, purchased from retail store in Korea, was investigated during the 2005. Applying pour plate method, the 1 mL of water samples were analyzed for the presence and enumeration of total general bacteria and Pseudomonas spp.. Nineteen samples representing 9 brands of bottled water contained general bacteria ($1.54{\times}10^2$ CFU/mL). In addition four samples contained Pseudomonas spp. and Camamonas acidovorans. The susceptibility of the strains tested against 25 antimicrobial agents, Pseudomonas fluorescens were resistant to Lincomycin, Amoxacilin/Clavulanic acid and Cefazolin (> $100{\mu}g/mL$). Also Comamonas acidovorans were intermediate to Cephalothin and resistant to Cefoperazone.

  • Objectives: Although water is essential for life and can supply essential minerals, studies that evaluate calcium intake through drinking water are limited. The aim of this study was to assess calcium contents of natural mineral water (NMW) and its possible contribution to calcium intake in healthy adults. Methods: This study examined water consumption in 640 Korean adults with self-selected diet, analyzed the calcium content of 10 different brands of bottled NMWs sold in Korea, and assessed the amount of calcium intake from drinking water and its daily contribution to the recommended nutrient intake (RNI) of calcium. Results: Mean calcium content in 10 bottled NMWs was 20.9 mg/l. Daily water intakes from food composition database and calculated using energy intake based on 0.53 ml/kcal were 957.2 ml and 1109.8 ml for men and 848.3 ml and 951.6 ml for women, respectively, with a significant difference by gender (p<0.001). Daily drinking water intake was significantly higher among men than women (1203.9 ml vs. 1004.3 ml, respectively, p<0.001). Daily calcium intakes from foods were 564.0 mg for men and 534.2 mg for women. Daily possible calcium intakes from drinking bottled water were 25.2 mg for men and 21.0 mg for women (p<0.001). The contribution of daily calcium intake from drinking bottled water to RNI of calcium was 3.3% for men and 2.9% for women without significant difference. Conclusions: One half of the daily total water intake was consumed as drinking water, and possible calcium intake through drinking water was about 3% of RNI.

  • 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 $0.39{\mu}g/L$, higher than PC bottles ($0.20{\mu}g/L$) and the raw water ($0.22{\mu}g/L$). The migration of Sb into water that is stored in different conditions (room temperature, $45^{\circ}C$, 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 $45^{\circ}C$, 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 $0.49{\mu}g/L$ in all simulated solution, which was far below the permissible korean migration level of $40{\mu}g/L$. There was a tendency that the number of re-use of a bottle and the amount of leaching were in inverse proportion.

  • The purpose of this study was to analyze and compare the contents of minerals and ionic components in domestic commercial natural mineral waters, and to investigate the relationship between water quality and characteristics of suspended and rocks there of its source. All mineral waters tested in this study met the korean mineral water quality guideline, although chemical components varied widely depending upon the geological characteristics and degree of urbanization of the source area or physical water treatment method. The water quality of commercial bottled water was different from that of source water, especially in cationic components, and showed a tendency to become worse with time elapsed. The water quality on the bottle was also different from the measured quality.

  • Community drinking water (CDW), mostly naturally flowing groundwater, plays important roles in supplying drinking water for urban and rural residents in Korea. Over 1,600 CDW facilities are distributed throughout the country, many of them situated in the outskirts of metropolitan cities. A large proportion of Korean people have become dependent on CDW for drinking due to a distrust of piped water's quality and a strong belief in the special medicinal effects of some CDWs. However, administrative and official management and the control of CDW facilities have been inadequate when compared with the strict examination and control of commercial bottled water, which is physically treated groundwater from deep bedrock aquifers. In this study, even though signs of anthropogenic contamination were not generally found, the tested chemical compositions of selected CDWs featured high enrichment of some constituents including Ca, Mg, Na, and HCO3 with natural origins such as water-rock interactions. Careless consumption of particular CDWs, which has no scientific basis, will not guarantee health improvement. Consequently, more intensive management of CDW facilities and a long-term interdisciplinary examination of the health effects of CDWs are needed to effectively protect people's health.
