摘　　要：目的了解淡化海水的水质特征,为制定相关饮水卫生标准提供参考。方法于2012年10月对我国某海岛地区3家淡化水厂的淡化水出厂水进行采样和检测。并采用GB 5749—2006《生活饮用水卫生标准》对淡化水的水质检测结果进行评价。结果淡化水的感官性状和一般化学指标均达标,淡化水总硬度<30 mg/L,硼的浓度为0.9～1.5 mg/L,虽超标,但低于WHO《饮水水质准则》(第4版)的指导值。其他理化指标符合饮用水卫生标准。结论淡化海水水质与传统自来水有差异,作为长期饮用水对人群健康的影响还需进一步探讨,建议制定海水淡化水的水质卫生标准。Objective To understand the quality characteristic of desalinated seawater and to provide suggestions for the relevant hygienic standards. Methods The desalinated seawater samples of three different desalinators were determined in October, 2012, and results were compared with the limits of GB 5749-2006 Standards for Drinking Water Quality. Results Total hardness of desalinated seawater was less than 30 mg/L and the boron content were 0.9-1.5 mg/L,higher than the limit value of GB 5749-2006, but lower than the guideline value of WHO Guidelines for Drinking Water Quality （the fourth edition）. Except for boron,the aesthetic and chemical indicators of desalinated water met the requirement of GB 5749-2006. Conclusion The quality of desalinated seawater is different from traditional tap water,the potential risks to human health of long-term drinking desalinated water should be further investigated and the hygienic standards need to be developed as soon as possible.
