“女人扒尿口”纯净水不宜长女人扒尿口期饮用?质检专家表示“没那么玄乎”

  近期女人扒尿口,有关纯净水不宜长期饮用的女人扒尿口话题再度被各方热议,纯净水、矿泉水是否有高低优劣之分?纯净水是不是真的不宜长期饮用?扬子晚报记者采访了南京市质检院的专家。

  包装饮用水主要分三类

  纯净水、矿泉水、蒸馏水……货架上的包装饮用水琳琅满目,到底有什么区别?南京市质检院食品检测研发部高级工程师徐美玲介绍说,按照国家标准,我们常见的包装饮用水主要分为饮用天然矿泉水、饮用纯净水和其他饮用水。根据GB 8537-2018《食品安全国家标准 饮用天然矿泉水》的定义,饮用天然矿泉水是指:从地下深处自然涌出的或经钻井采集的,含有一定量的矿物质、微量元素或其他成分,在一定区域未受污染并采取预防措施避免污染的水。

  饮用纯净水,以符合GB 5749-2022《生活饮用水卫生标准》的可以来自公共供水系统,也可以来自非公共供水系统的地表水或地下水为原料,采用蒸馏法、电渗透法、离子交换法、反渗透法或其他适当的水净化工艺,加工制成的包装饮用水。自然来源饮用水(饮用天然水),以符合GB 5749-2022《生活饮用水卫生标准》的非公共供水系统的地表水或地下水为原料,仅通过脱气、曝气、倾析、过滤、臭氧化作用或紫外线消毒杀菌过程等有限的处理方法,不改变水的基本物理化学特征的自然来源饮用水。

  合格饮用水没有优劣之分

  饮用水市场纯净水、矿泉水之争由来已久,且有观点认为纯净水在净化的过程中,去除水中杂质的同时,也把对人体有益的钙、镁、铁、锌等物质一并去除了,长期饮用可能会对健康产生不利影响。徐美玲在接受采访时表示,人们喝水主要目的是为了补充身体所需要的水分,人体所需的各种营养物质主要还是通过膳食来摄入。

  在徐美玲看来,不管是矿泉水还是饮用纯净水,并没有高低优劣之分,只要符合国家标准要求的饮用水,都可以放心适量饮用。与其关注包装饮用水是否有“营养”,不如多关注其卫生指标。建议消费者在选购包装饮用水时,留心观察产品标签上的食品名称、配料表、食品生产许可证等信息。

  高温暴晒过的水并未变质

  对于包装饮用水,一度还有高温暴晒后会致癌的说法。对此,南京市市场监管局也进行了测试。

  质检人员选取了超市里常见的10种品牌瓶装饮用水作为测试对象,将未开封的瓶装水分别放置在车内后备箱和前排座位上,主要区别在于前者所处环境是高温避光,后者是高温且阳光直射。通过连续10天的取样检测,结果显示,各类饮用水均未检出塑化剂,微生物结果也符合食品安全国家标准限量。
