The purpose of study was to evaluate and compare chemical quality of Iranian bottled drinking water reported on manufacturer's labeling and standards.
This study was a cross-sectional descriptive study and done during July to December 2008. The bottled mineral water collected from shops randomly were analyzed for all parameters address on manufacturer's labeling and the results were compared with the manufacturer's labeling data, WHO Guideline Values, USEPA Maximum Contaminant Levels and the maximum contaminant levels of drinking water imposed by the Iranian legislation. Statistical analysis on data was done with the Kolmogorov-Smirnov test for normal distribution, the paired t-test to compare the data with manufacturer's labeling and the one-sample t-test to compare with standard and MCL values at P 0.05). In addition, pH and calcium values were significantly higher than their proposed values indicated by Iranian National Legislation and international MCLs (P< 0.05).
Our results are extremely important for the health supervisory agencies such as Ministry of Health and Institute of Standards & Industrial Research of Iran to have more effective controls on bottled water industries, and to improve periodical the proposed standard values.
本研究的目的是评估和比较伊朗瓶装饮用水在制造商标签及标准中所报告的化学质量。
本研究为横断面描述性研究，于2008年7月至12月期间进行。从商店随机收集瓶装矿泉水，对制造商标签上提及的所有参数进行分析，并将结果与制造商标签数据、世界卫生组织指导值、美国环境保护局最大污染物水平以及伊朗立法规定的饮用水最大污染物水平进行比较。数据的统计分析采用Kolmogorov-Smirnov检验进行正态分布检验，采用配对t检验将数据与制造商标签进行比较，采用单样本t检验与标准值和最大污染物水平值进行比较（P<0.05）。此外，pH值和钙含量显著高于伊朗国家立法和国际最大污染物水平所建议的值（P<0.05）。
我们的结果对于伊朗卫生部和标准与工业研究机构等健康监管机构极为重要，有助于对瓶装水行业进行更有效的监管，并定期改进建议的标准值。
