【摘要】 目的:了解淡化海水作为饮用水水源长期饮用对人群健康可能造成的潜在危害,以及为制定干预措施和相关卫生标准提供参考依据。方法:根据《生活饮用水标准检验方法》(GB5750-2006)要求,2007年~2008年四次对嵊泗海水淡化出厂水进行了采样和检测。按照《生活饮用水卫生标准》(GB 5749-2006)要求对检测结果进行评价和分析。结果:嵊泗本岛海水淡化出厂水感官性状指标基本符合生活饮用水卫生标准;化学指标检测发现:海水最突出的高盐高渗透的问题得到有效解决,影响海水不能饮用的主要化学指标钾、钠、总硬度、溶解性总固体、氯化物、硫酸盐等均已降至卫生标准值以下,但存在普遍硼超标以及淡化海水的典型的"软水"现象。结论:淡化海水作为长期饮用水对人体健康的潜在危害值得进一步研究和探讨。更多还原

【Abstract】 Objective:To find out the potential risks to the crowds drinking treated water by reverse osmosis method for seawater desalination in long term,and to provide counter measure and foundation for the relevant hygienic standard.Methods:In accordance with the requirement of standard examination methods for drinking water(GB5750-2006),treated water samples have been detected four times in different seasons from seawater deslaination plant in Shengsi islands in 2007~2008.Results:The sensory characteristic indicator of treated water was basically in the line of Standards for Drinking Water Quality(GB 5749-2006),chemical index shew that the problem of high permeability in highly saliferous seawater has been effectively solved,the indicators of potassium,sodium,total hardness,total dissolved solids,chlorid,sulphate etc.,were reduced to standard level,but the universal phenomenon for out of limits of boron and the typical soften water were always existed.Conclution:It is worthwhile to investigate furthmore the potential risks to human body for drinking treated water by in long term in Shengsi islands.更多还原
